It holds the distinction of being the first fully purple sprouting broccoli commercially available: unlike traditional purple sprouting broccoli where only the florets carry colour, Tyrian carries its rich purple through the leaf veins, the stems and the florets all the way down. It is a Brassica oleracea italica and a summer sprouting type, meaning it does not require the long dormant overwintering period of traditional purple sprouting varieties. That makes it a significantly faster and more accessible crop, with a harvest window running from April through to October depending on sowing date. Plants grow to around 80cm tall with a neat, upright habit that makes it tidy on the plot and straightforward to harvest.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy it is good\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTyrian is not just visually striking, it is genuinely delicious. The flavour is sweet and mild, with a soft, low fibre texture in both the stems and florets that works beautifully raw, steamed, stir fried or briefly boiled. The deep purple colour, which comes from a high concentration of anthocyanins, is retained best when the shoots are steamed or stir fried quickly rather than boiled at length. Those anthocyanins are also one of the reasons purple brassicas are so nutritious: they are powerful antioxidants that make Tyrian one of the more health oriented vegetables you can grow on the plot. As a summer sprouting variety it fills a genuinely useful seasonal gap, producing harvests through late spring and summer when traditional purple sprouting broccoli is long finished and the main calabrese crop is not yet ready. Cut regularly and the plants continue producing side shoots across a long season.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGrowing performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTyrian is vigorous and grows quite straight upwards with a uniform, tidy habit that makes harvesting straightforward. It prefers a sunny position in firm, fertile, well drained soil with good organic matter worked in before planting. As with all brassicas, firm planting is important, and the soil should be prepared a few weeks in advance to allow it to settle. Space plants 60cm apart in both directions to give them room to develop fully and allow airflow around the foliage. Net with fine mesh from transplanting to protect against cabbage white butterflies and pigeons, both of which are serious problems if left unchecked. Follow a brassica rotation and do not grow in ground used for the cabbage family in the previous year. The variety is described as an excellent performer in garden trials and has demonstrated strong reliability across a range of growing conditions.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHarvest and outcome\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCut shoots from April through to October, harvesting when they are around 10 to 15cm long, using a sharp knife or scissors just above a leaf joint. Regular cutting is essential to keep the plant producing: once you stop picking, the plant shifts its energy into seed production and the harvest ends. The purple colour in both stems and florets makes it visually distinctive at the table and one of the more appealing raw vegetables for salads and crudités. When cooked, the colour softens but the sweet, tender flavour remains excellent. The stems are fully edible as well as the florets, which reduces waste and gives you more usable material per plant than many other sprouting broccoli types.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWho it is for\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTyrian suits any grower who wants something genuinely new on the plot alongside their regular brassica rotation. It is a natural choice for kitchen gardeners who value both flavour and appearance in what they grow, and for allotment growers who want to cover the seasonal gap between spring crops and summer harvest. Growers who have struggled with the long lead time of traditional purple sprouting broccoli will find the faster turnaround of a summer sprouting variety much more manageable. It is also an excellent variety for anyone cooking for people who are normally resistant to broccoli: the colour, the sweetness and the tender stems make it a more persuasive vegetable all round.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Mr Fothergill's","offers":[{"title":"Default Title","offer_id":52214984474962,"sku":"5011775438092","price":4.69,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/6260\/9746\/files\/mr-fothergills-rhs-broccoli-tyrian-f1-seeds-purple-stem-summer-sprouting-vegetable-seeds-5011775438092-5011775438092-mr-fothergills-shop-now-at-allotmate-essent-6313832.jpg?v=1777981033"},{"product_id":"rhs-brussels-sprout-igor-f1","title":"Mr Fothergills RHS Brussels Sprout Igor F1 Seeds AGM Sweet Winter Crop","description":"\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat it is\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBrussels Sprout Igor F1 is a reliable late season F1 hybrid variety from Mr Fothergill's Seeds, produced in partnership with the RHS and awarded the RHS Award of Garden Merit for its consistent performance and excellent flavour in British growing conditions. It is a Brassica oleracea var. Gemmifera, grown for its abundant crop of solid, mid-green buttons which form tightly and uniformly along the full length of the plant stem. Igor F1 is a vigorous, strong growing variety that stands well in the ground through the winter without deteriorating, making it one of the most practical and rewarding Brussels sprout varieties you can grow for a Christmas and New Year harvest that continues right through to March.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy it is good\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIgor F1 is notably sweet for a Brussels sprout, with a mild, nutty flavour that improves meaningfully after a frost, which is one of the reasons late season varieties like this are so valued by serious growers. The buttons are solid and well filled rather than loose and open, which matters both for flavour and for how they cook: tight sprouts steam, roast and stir fry far better than looser ones. Yields are impressive, with plants producing abundantly from top to bottom of the stem, and the standing ability through hard winters means you can harvest as you need rather than picking everything at once and trying to store it. It is also suitable for all soil types, which removes one of the common barriers to growing sprouts successfully on more challenging plots.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGrowing performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eBrussels sprouts are a long season crop and Igor F1 is no exception: sown indoors from February, transplanted in April or May, and not ready until December. That timeline requires some planning but the reward is a self-sustaining source of fresh, nutritious vegetables through the coldest months of the year when the rest of the plot has very little to offer. Plants grow to a medium height of around 75 to 80cm and benefit from a sunny, sheltered position in firm, fertile, well drained soil. Firm planting is important as loose soil causes plants to rock in autumn winds, which reduces sprout quality. Earth up around the stems in autumn and stake taller plants in exposed positions if needed. As with all brassicas, crop rotation is essential: do not plant in ground used for brassicas in the previous year, and net with fine mesh from transplanting to protect against cabbage white butterflies and pigeons.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHarvest and outcome\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eHarvest from December through to March, working from the bottom of the stem upwards: the lowest buttons mature first. Pick when buttons are firm, tight and around 2.5 to 4cm across, and remove the leaf below each picked sprout as you work your way up the plant. Regular picking encourages the upper buttons to develop and keeps the harvest going over a long period. Do not pick too early: buttons benefit noticeably from a few hard frosts, which convert starches to sugars and give the sprout its characteristic sweetness. Once most of the stem is harvested, the leafy top rosette of the plant, known as sprout tops, can be picked and cooked as a tender, flavourful green.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWho it is for\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"standard-markdown grid-cols-1 grid [\u0026amp;_\u0026gt;_*]:min-w-0 gap-3\"\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIgor F1 is an excellent choice for any grower who wants fresh homegrown vegetables on the table through the deepest part of winter.

Kitchen gardeners who cook regularly from December through to spring will find it one of the most productive and satisfying things they can grow. For anyone who has dismissed Brussels sprouts as difficult or bitter, Igor F1 is a genuinely convincing argument to reconsider: properly grown from seed, picked after a frost and eaten fresh from the plot, they are a completely different vegetable to the ones most people remember.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Mr Fothergill's","offers":[{"title":"Default Title","offer_id":52214984769874,"sku":"5011775325873","price":3.79,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0808\/6260\/9746\/files\/mr-fothergills-rhs-brussels-sprout-igor-f1-seeds-agm-sweet-winter-crop-vegetable-seeds-5011775325873-5011775325873-mr-fothergills-shop-now-at-allotmate-essentia-1148807.jpg?v=1777981032"},{"product_id":"rhs-cabbage-red-rookie-f1","title":"Mr Fothergills RHS Cabbage Savoy Tundra F1 Seeds AGM Winter Hardy","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhat it is\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eCabbage Savoy Tundra F1 is a modern F1 hybrid winter cabbage from Mr Fothergill's Seeds, produced in partnership with the RHS and awarded the RHS Award of Garden Merit for its outstanding reliability and performance. It is a Brassica oleracea variety that sits between two worlds: it carries the deeply crinkled, dark green savoyed foliage and exceptional frost hardiness of a traditional savoy cabbage, and combines it with the crisp, dense, well structured head of a white ball head type. The result is a winter cabbage that neither compromises on flavour nor on appearance, and which sets a genuinely high standard for what a homegrown winter brassica can be.

It is exceptionally frost hardy, capable of standing in the ground through hard British winters without deteriorating, and once mature it holds well from November right through to April. That standing ability is a significant practical advantage, effectively turning it into a living store rather than requiring you to harvest and refrigerate at a fixed point. The flavour is sweet and nutty, improved by cold weather rather than damaged by it, and the crisp texture works equally well shredded raw into coleslaw, braised in a winter stew, or simply steamed alongside a roast. It is also a quick maturing variety for a winter cabbage, typically reaching harvest around 110 days from planting.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGrowing performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTundra F1 is straightforward to grow but benefits from good soil preparation and a disciplined approach to brassica rotation. It prefers a sunny position in firm, fertile, well drained soil with a neutral to slightly alkaline pH: if your soil tends to be acidic, liming before planting is worth doing. Incorporate plenty of well rotted organic matter ahead of planting, ideally a few weeks in advance to allow the ground to settle. Space plants around 45 to 60cm apart with 60cm between rows to allow heads to develop fully and reduce the risk of disease. As with all brassicas, do not grow Tundra F1 in a spot where cabbage or other brassicas were grown the previous year. Net the crop with fine mesh from the outset to protect against cabbage white butterflies and pigeons, both of which will find it without much trouble. Feed regularly with a potassium rich fertiliser through the growing season and water consistently, especially during dry spells, as irregular watering can cause heads to split.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHarvest and outcome\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eHeads are ready from November onwards and will stand happily in the ground until April, giving you one of the longest harvest windows of any vegetable on the plot.

The dark green, crinkled outer leaves protect the inner head through cold weather, and the crisp interior holds its quality well even after prolonged hard frosts. Surplus heads can be stored in a cool, frost free place for several weeks.

The result is a winter cabbage that neither compromises on flavour nor on appearance, and which sets a genuinely high standard for what a homegrown winter brassica can be. Compact heads weigh in at around 1.25 to 2.5kg with a neat, tidy appearance that makes it as satisfying to harvest as it is to grow.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWhy it is good\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTundra F1 earns its place on the plot because it fills a gap that very few crops can cover: deep winter, when most of the veg garden has nothing left to offer. It is exceptionally frost hardy, capable of standing in the ground through hard British winters without deteriorating, and once mature it holds well from November right through to April. That standing ability is a significant practical advantage, effectively turning it into a living store rather than requiring you to harvest and refrigerate at a fixed point. The flavour is sweet and nutty, improved by cold weather rather than damaged by it, and the crisp texture works equally well shredded raw into coleslaw, braised in a winter stew, or simply steamed alongside a roast. It is also a quick maturing variety for a winter cabbage, typically reaching harvest around 110 days from planting.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eGrowing performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTundra F1 is straightforward to grow but benefits from good soil preparation and a disciplined approach to brassica rotation. It prefers a sunny position in firm, fertile, well drained soil with a neutral to slightly alkaline pH: if your soil tends to be acidic, liming before planting is worth doing. Incorporate plenty of well rotted organic matter ahead of planting, ideally a few weeks in advance to allow the ground to settle. Space plants around 45 to 60cm apart with 60cm between rows to allow heads to develop fully and reduce the risk of disease. As with all brassicas, do not grow Tundra F1 in a spot where cabbage or other brassicas were grown the previous year. Net the crop with fine mesh from the outset to protect against cabbage white butterflies and pigeons, both of which will find it without much trouble. Feed regularly with a potassium rich fertiliser through the growing season and water consistently, especially during dry spells, as irregular watering can cause heads to split.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHarvest and outcome\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eHeads are ready from November onwards and will stand happily in the ground until April, giving you one of the longest harvest windows of any vegetable on the plot. Harvest when heads feel firm and dense to the touch, cutting cleanly at the base with a sharp knife. The dark green, crinkled outer leaves protect the inner head through cold weather, and the crisp interior holds its quality well even after prolonged hard frosts. Surplus heads can be stored in a cool, frost free place for several weeks. The flavour is genuinely at its best after a frost, which intensifies the natural sweetness: worth timing at least one harvest to coincide with a cold snap if you can.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eWho it is for\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eTundra F1 is an excellent choice for any grower who wants fresh, homegrown vegetables on the table through winter without relying on a polytunnel or indoor growing setup. It suits allotment growers who plan their rotation carefully and want a reliable, high quality crop to fill the hungry gap. Kitchen gardeners who cook regularly through winter will find it one of the most useful varieties they can grow: hardy enough to ignore and versatile enough to use in almost any winter dish.
