Igloo Cauliflower is a cold-hardy cultivar that matures in just 70 days, making it one of the quickest cauliflowers to reach the table. This non-GMO variety thrives in colder temperatures where other brassicas struggle, and it offers remarkable flexibility, you can harvest smaller heads by planting closer together for faster yields, or wait for larger heads if you prefer. Its ability to produce abundant cauliflower in tight spaces and short seasons makes it especially valuable for northern gardeners and those working with limited room.

Highlights
What sets Igloo apart is its genuine cold tolerance combined with genuine speed. Unlike many cauliflower varieties that sulk in cool weather, Igloo actually performs better in it, giving gardeners in short-season climates a reliable source of crisp, white heads. The flexibility to control final head size through spacing decisions means you're not locked into one harvest window, plant densely for baby cauliflowers or give plants room to develop substantial crowns. This is cauliflower that works with your climate instead of against it.
Common Uses
Igloo Cauliflower is grown primarily for fresh harvest and kitchen use. The compact heads are excellent roasted, steamed, or eaten raw in salads and vegetable platters. The variety's ability to produce smaller heads when plants are spaced closely makes it particularly suited to families who prefer bite-sized portions or home gardeners seeking multiple small harvests rather than one large head.

Care Instructions
Harvesting
Harvest Igloo Cauliflower when heads reach your desired size, typically 70 days after planting. For smaller heads, harvest as soon as they feel firm and compact; for larger crowns, allow additional time for head expansion. Cut heads at the base of the stem with a sharp knife. The flexibility to choose harvest size means you can begin picking while heads are still developing and take what you need, or wait for full maturity, either approach works with this cultivar.
