Long Island Improved Brussels sprouts (Brassica oleracea var. gemmifera) is the classic heirloom that produces tall stalks studded with dozens of firm, 1–1.5 inch sprouts. These Brussels sprouts seeds grow into sturdy, upright plants that yield a heavy, uniform crop of tightly packed, sweet-nutty sprouts. It’s a dependable, high-yielding variety bred for compact plants and long harvest windows.

Who it’s for

Best for patient, cool-season gardeners who want a big fall harvest of homegrown sprouts that sweeten after frost.

How & when to plant

Start seeds indoors 4–6 weeks before the last spring frost, or sow in early to midsummer for a fall crop. Plant 1/4–1/2 inch deep and transplant 18–24 inches apart in full sun with rich soil. Brussels sprouts need a long, cool season and grow well in USDA zones 3–9. A light frost improves flavor.

Harvest

Sprouts are ready in about 90–100 days. Pick from the bottom of the stalk upward once sprouts reach 1–1.5 inches and feel firm, twisting them off by hand. Harvest after a light frost for the sweetest flavor.

Benefits & uses

Roasted, sautéed, or shredded raw into slaws, these sprouts offer a sweet, nutty flavor that’s a fall and winter kitchen staple. Their firm texture holds up well to roasting and pan-searing.

FAQ

Long Island Improved is a long-season crop that needs about 90 to 100 days to mature. The sprouts develop from the bottom of the stalk upward as the season cools.
Because they need a long, cool finish, start seeds in late spring to early summer so sprouts mature in fall. A light frost actually sweetens the sprouts.
Space plants 18 to 24 inches apart in rows about 30 inches apart. They grow tall and heavy, so firm soil and occasional staking help keep them upright.
Pick sprouts from the bottom of the stalk first, once they are firm and about 1 inch across, working upward over several weeks. Removing lower leaves helps the sprouts size up.
They are rewarding but take patience because of the long season and need for cool fall weather. Timing the planting so they mature in autumn is the main key to success.
This packet contains about 950 heirloom, non-GMO seeds, more than enough for a full planting plus extras.
Cold weather converts starches to sugars, so a light frost makes the sprouts noticeably sweeter.
Brussels sprouts need a long season, typically about 90–100 days from transplant to first harvest.
