Autumn Star Kalettes Brussels Sprouts deliver a harvest of nutrient-dense mini cabbages that taste far better than their reputation suggests. These compact buds from the Brassica oleracea Gemmifera Group pack nearly 150% of your daily vitamin K requirement into just over a cup, along with exceptional levels of dietary fiber and immune-supporting compounds. Grow them in full sun with consistent moisture, spacing plants 4 inches apart in rows 18 inches wide, and you'll be harvesting firm, 1- to 1.5-inch buttons from late fall through early winter when frost actually improves their flavor.

Each tiny button delivers a concentrated dose of health-promoting indole-3-carbinol, an anti-bacterial and anti-viral agent that works as an effective immune regulator. The flavor deepens after a hard frost, making these a genuine cold-season treasure rather than a summer afterthought. You harvest from the bottom up, letting upper sprouts continue maturing on the stalk, which means a single planting delivers weeks of continuous picking rather than a one-time haul.
These mini cabbages shine roasted until their outer leaves turn crispy and caramelized, or shredded raw into slaws where their compact texture holds dressing beautifully. They're small enough to halve and serve as a single bite, making them especially useful for composed vegetable plates or as a sophisticated side dish where presentation matters. Their high nutritional density means they've become a staple for health-conscious gardeners and anyone serious about growing nutrient-rich vegetables.
No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your anticipated transplant date. This head start is essential for these Brussels sprouts to reach maturity in time for fall and early winter harvest.
Transplant outdoors once seedlings are established and ready to be hardened off. Timing matters: you want plants to mature during cool fall weather when they'll develop their best flavor and texture.
Direct sowing is not recommended for this variety; indoor starting is the reliable path to success.
Begin harvesting when the bottom sprouts reach 1 to 1.5 inches in diameter, feeling firm and well-formed. Pick from the bottom of the stalk upward, allowing upper buttons to continue maturing as you remove the lower ones; this staggered harvest extends your season over weeks. You can also harvest the entire stalk at once by cutting off the top at the growing point once sprouts are present throughout the plant and bottom sprouts measure 1/2 inch in diameter; the remaining buds will mature fully within a couple of weeks. Timing is flexible within reason, but wait until after at least one frost for the best flavor. Stop harvesting before temperatures drop below 20 degrees Fahrenheit, as prolonged exposure to extreme cold can damage the sprouts.
