Gardeners' Notes:

This vine has lovely deep blue (not violet) rounded flowers and nice, soft, rounded foliage that presents well on soft tendrils. There are no thorns, and it can be easily trained. I sowed 10 seeds indoors as directed, waited 3 months, and never saw a sprout. So I tossed the tray of soil and seeds in our front garden. A month later I noticed 2 unusual and pretty seedlings in full sun beside my day lilies. Ta-da! Blue pea vine after all. I moved them to pots to take indoors soon. They look awesome next to Fuschia gartenmeister, which I also take inside and get blooms all winter on when placed by sunny south windows.

If you like growing vines, this one is a must have. It is very easy to grow and self seeds for plenty of babies the following year. I planted my vine last year and it even stayed green all winter long! The blooms are a vibrant blue that adds brilliant color to your garden.
