About Long Island Improved Brussels Sprouts Seeds
Brassica oleracea var. gemmifera
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.

| Start Indoors | 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. |
| Direct Sow | 4 months before your average first fall frost date, when soil temperature is at least 40°F. |
| Growing & 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. |
