Silvia Brussels Sprouts is a reliable, cool-season brassica that matures in 103 days, producing firm sprouts on plants that reach 20-24 inches tall. This variety thrives in full sun with moderate watering and prefers soil with a pH between 6.5 and 7.5. Silvia handles frost well, making it an excellent choice for fall gardens where cooler temperatures help the sprouts develop their characteristic flavor and texture.

Silvia's 103-day maturity window aligns perfectly with fall growing schedules, allowing gardeners to time plantings so harvest coincides with the first frosts that actually improve sprout quality. The compact 20-24 inch plant height makes it manageable in most garden spaces, while its frost-hardy nature means you can extend the harvest well into late autumn. This variety carries resistance to Fusarium yellows, protecting your crop from one of the most common and destructive brassica diseases.
Brussels sprouts are harvested and prepared by removing individual sprouts from the stem for roasting, sautéing, steaming, or braising. The entire plant is edible, and many gardeners also harvest the top leafy crown for cooking once the lower sprouts are picked. Silvia works equally well for fresh eating and storage.
No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your transplant date, which should be timed for 4 months before your average first fall frost date. Sow seeds 1/4 inch deep in seed-starting mix and maintain soil temperatures around 60-85°F for germination, though seeds will germinate at a minimum of 40°F. Keep soil consistently moist until seedlings emerge. In mild climates, you can also sow directly in fall for harvest in late winter and early spring.
Transplant seedlings outdoors 4 to 6 weeks after starting them indoors, timing this so plants mature during cool fall weather. Space plants 24 inches apart in rows 24 inches apart. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days before planting out.
Direct sow outdoors when soil temperature reaches at least 40°F, typically 4 months before your average first fall frost date.
Silvia reaches harvest readiness at 103 days from transplanting. Begin picking sprouts from the bottom of the stem upward once they reach about 1-1.5 inches in diameter and feel firm to the touch. Harvest by twisting or cutting individual sprouts cleanly from the stem. Continue harvesting as more sprouts develop up the plant. Frost actually improves flavor, so waiting until after the first light frosts will give you sweeter, more tender sprouts. The entire plant can be harvested once sprout production slows.
