Description
The Swallow‑tail morning glory is an annual vine that can cover fences and obelisks with sky‑blue funnel‑shaped flowers in a single season. Each flower opens in the morning and wilts by evening, but dozens of new blooms appear daily. The seeds are toxic and should not be handled by children.
Care instructions
Sow the seeds from May (week 18) directly outdoors or start them indoors on a windowsill in April. Harden hard seeds by soaking them overnight in lukewarm water. Provide a sunny, warm spot and a trellis or string for climbing. Water evenly and fertilize sparingly; heavy feeding will produce more foliage at the expense of flowers.
