Asclepias cordifolia, or Heartleaf Milkweed, is a native perennial known for its heart-shaped leaves and clusters of pale pink to lavender flowers. Its intricate blossoms attract pollinators while serving as a host plant for Monarch butterfly larvae. Thriving in well-draining soil and full sun, it's drought-tolerant and adapts to various habitats. This milkweed variety adds beauty to gardens, supports local ecosystems, and contributes to Monarch conservation efforts. Zones 7-10.
Germination
To germinate Asclepias cordifolia seeds, begin by preparing a seed starting tray or small pots filled with a well-draining seed starting mix, such as a combination of peat moss and perlite. Sow the seeds on the surface of the soil and gently press them into the mix, ensuring good soil contact. Since Asclepias cordifolia seeds require light for germination, avoid covering them with additional soil. Keep the soil consistently moist but not waterlogged by misting regularly or using a gentle watering can. Place the tray or pots in a warm location with indirect sunlight, maintaining a temperature between 70-85°F (21-29°C). Germination typically occurs within 14-30 days. Once the seedlings emerge, provide adequate spacing if growing in trays, or transplant them into individual pots when they have developed a few sets of true leaves. Asclepias cordifolia prefers full sun and well-drained soil. Continue to care for the seedlings with proper watering and light as they grow into mature Asclepias cordifolia plants.
