Each plant generates up to 12 stems, multiplying your harvest and your arrangement options without requiring the deadheading or staking that traditional peonies and mums demand. The golden centers reveal themselves as blooms fully open, creating a layered visual richness. Once cut, these flowers hold up remarkably well in water, making them as reliable in a vase as they are in the garden.
Yellow Aster excels as a cut flower for spring arrangements and bouquets. The abundant stems and large blooms make it a prolific producer for both fresh-cut displays and garden color.
No timeline data available yet for this variety.
Sow seeds indoors 6-8 weeks before your last frost date. Keep soil at 70-80°F for reliable germination. Provide bright light once seedlings emerge.
Harden off seedlings over 7-10 days by gradually exposing them to outdoor conditions. Transplant after all danger of frost has passed and soil has warmed. Space plants 12-18 inches apart to allow room for the multiple stems to develop without crowding.
Cut blooms when petals are fully open and the golden yellow centers are visible, using sharp scissors or shears. Cut stems in the early morning or evening when hydration is highest. Remove flowers regularly to encourage the plant to produce more stems and blooms throughout the season.
