Eat your Flowers

Same with Vinca, https://pfaf.org/user/plant.aspx?latinname=Vinca+major Not edible and its only saving grace is that the stems can be used to make baskets!!! So its days are numbered.

I retrieved a handful of stems off my rubbish compost heap (stuff that might grow again compost heap ).

not the best basket you will of ever seen. Only my second ever attempt at basket weaving. But you can definitely make baskets form vinca / periwinkle.
