Annual. A very tenacious vine is adorned with beautiful blue flowers- but only before the sun hits them in the morning! Once the first few hours of the morning have passed, the blue flower transitions to purple, then pink, and then shrivels away just to be replaced by more blooms the following morning. Plant in an area where you do not mind a somewhat aggressive vine sprawling around. Plants require trellising for optimal growth and bloom production. Start outdoors after all danger of frost has passed. Soaking seed in warm water 12-24 hours before planting can aid in germination. 10-15 seeds per pack.
