Gardeners' Notes:

Positive Texasbloomer On Sep 18, 2005, Texasbloomer from Plano, TX wrote:

An awesome blue-bloomer! The one I planted (early May in a pot) [in our friends' yard) (darn) is 8' but now is in the ground. 20+ blooms a day, minimum since mid-Aug. Has only shot out 2 or 3 little seed pods. Blondie-seeds! I planted a few seeds in my own yard mid Aug. and they're up 3' with a couple of low-to-the-ground blooms each day just this week. What a pretty blue and pattern!

Very beautiful watercolor effect! They truly are an outstanding flower. Flower color can vary from vine to vine.

Another very large flowered Japanese Morning Glory but the same draw backs as the others. Wind and rain take a terriable tole on these beautiful flowers.
Very pretty pale blue with picotee edging..........very,very pretty.

I have been growing this for several years but am unable to collect seed due to our short growing season. It is just lovely and a color not often found in the garden.
