Lathyrus sativus
I wish for a truly blue pea flower, so L. sativus Blue and Azureus I had a little go at this year.
Delighted by the flower colour but individual plants don't offer much by way of floral display.
In what density will I need to plant them to achieve pretty patch. I guess it will be impossible to deadhead throughout their season, possibly have to go about combing over the area to either remove all the seed, or leave them as a permanent patch of self seeding?
