The real appeal lies in how quickly this climber establishes itself, unfurling delicate flowers for nearly half the year across warm climates. Seeds germinate in just 10 to 20 days when kept at 65 to 70 degrees, and flowers appear reliably from June through November. Its moderate water needs and full sun preference make it straightforward to grow once established, especially in well-draining soil enriched with compost.
Sky Blue Asarina excels as a vertical accent in gardens where you need fast-growing coverage on trellises, arbors, or garden structures. The climbing habit and extended bloom window make it valuable for creating living screens or adding seasonal color to bare walls and fences in warm-season gardens.
No timeline data available yet for this variety.
Sow seeds indoors 10 to 12 weeks before your last frost date. Surface sow the seeds and press them in lightly without covering; they need light to germinate. Keep the soil at 65 to 70 degrees Fahrenheit. Seeds typically sprout in 10 to 20 days. Transplant seedlings outdoors after frost danger has passed.
Move seedlings outdoors after your last frost date when soil has warmed. Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days before planting in the garden.
In warmer climates (zones 8 and above), direct sow seeds after the last frost date. Surface sow and press seeds in lightly, keeping soil consistently moist until germination occurs.
