A reminder to anyone who's gotten seeds of Blue Pea Vine (Clitoria terneata) from me the last few months...even when the pods are picked from vines bearing double flowers that are the best for eating (much more substance to them than the single flowered form that is so lovely in the garden), only a small number of seedlings, maybe 10%, become vines with double flowers. But in summer they grow rapidly, so one can pull up single flowered vines as they bloom when young. I eat the double flowered blooms raw....much like a slightly aromatic lettuce. In Malaysia the blooms are added to rice as it cooks to make it a lovely lavender color for special occasions....I did it once, it worked!
