Modern chefs have transformed this historically disliked vegetable into a much-sought-after food that is delicious deep fried, steamed, or roasted. Give them plenty of water, nutrients, and time to grow before they begin forming sprouts. Covering plants with row covers after sowing/transplanting will help exclude pests. You can leave plants in the garden into the winter, as they are hardy to 10°F; frost actually improves the flavor. The plants resemble little palm trees.
$1.99 1 gram (~140 seeds)

Botanical Name: Brassica oleracea var. gemmifera

Days to Maturity: 85–110 days

Family: Brassicaceae

Native: Europe

Hardiness: Frost-tolerant biennial; will tolerate temperatures to about 10?F.

Plant Dimensions: 20"–24" tall

Variety Information: 1"–1½", blue-green orbs that look like tiny cabbage heads, and grow tightly and densely against the main trunk of the plant. The cluster of leaves at the top of the plant give it a palm-tree-like look. 'Long Island Improved' was developed in the 1890s, quickly becoming the garden standard, and continues to be a dependable heirloom for home gardeners.

When to Sow Outside: 4 months before your average first fall frost date, when soil temperature is at least 40°F.

When to Start Inside: RECOMMENDED. 4 to 6 weeks before transplanting outside, about 4 months before your average first fall frost date so sprouts mature in cool weather. In mild climates, sow in fall for harvest in late winter and early spring. Optimal soil temperature for germination is 60°–85°F.

Days to Emerge: 5–10 days

Seed Depth: ¼"

Seed Spacing: A group of 3 seeds every 24"

Row Spacing: 24"

Thinning: When 2" tall, thin to 1 every 24"

Harvesting: Brussels sprouts start maturing from the bottom of the plant to the top. Buds should be picked when they are firm and about the size of a large cherry, between 3/4" and 1" in size. Break off the leaf just below the buds and snap or cut off the sprout. Brussels sprouts can be left in the garden through a freeze, which sweetens the flavor.

Long Island Improved Brussels Sprouts Seeds Reviews

Toughest little seedling that can survive anything!

5 out of 5 stars Jan 26, 2021
I planted some seeds in some module trays and waited for them to sprout. The day they germinated though, there was a violent windstorm which knocked over my plastic greenhouse. The plants fell over, but they handled it like champs! The plants survived, and are still growing happily in my garden. I'm amazed!

I started these by seed and they germinated great. They are huge plants, but I've seen nothing to harvest. I'm not sure I will plant again next year.

Owner Response: Hi Toni, Brussels sprouts take a long time to mature and form sprouts (85-110 in ideal conditions). They just need a little more patience to produce.

These brussels were challenging to get started and produced zero brussels sprouts. A waste of garden space.

Owner Response: Hi Teresa, We hope you know you can reach out to customer service or our horticulture at any time to get help troubleshooting growing issues. From your reviews today it seems you've had good germination, but a few issues growing this year and we are happy to help. We are glad you had good germination with these seeds. Brussel sprouts take quite a long time to produce buds. These seeds came from plants that produced sprouts which eventually flowered and produced seeds. The plants either needed more time or different environmental variables, for example, excess nitrogen can stifle flower productions (sprouts).
