Pretty, but not showy. Better as a filler in the flower garden, or leaning against a Clematis or Rose. It can also be used to spill out of large containers and window boxes. Also, I think this plant needs to be grown near the path or patio as you really need to get close to fully appreciate it. It is among the bluest of flowers. Unlike Sweet Peas (odorata) it takes heat well. A small clarification,: "Azureus" is not a cultivar; rather, it is a natural variation of bloom color.

Commonly grown in China and India as a grazing crop for animals, where over 4 million acres are in cultivation. Toxic, like all other sweet peas, but researchers are working to develop strains that will be edible for humans in drought-striken countries. This one is rarely offered. Does well even in the heat of summer. Annual, low-growing 1-2' plants.

The expensive seed packet declared "a profusion blue blossoms" on this sweet pea relative. In my Cape Cod garden I have been able to grow this pleasant legume with enough blooms to entertain me, but I think "Profuse" is overstating its virtues. It has left me with enough seed pods to replant, which I have done, as it's pretty enough and harmless. I've decided that it's worth sticking seeds in my herb patch here and there to meander and blossom, and possibly improve the soil, but I'm not terribly impressed with it otherwise.
