Sarah and I were talking about blue foliage plants this afternoon. She’d been thinking of a blue hosta for a friend’s garden. Large blue leaves would be just the right counterpoint to her friend’s fine-textured gold spirea. Trouble is, that spot in the garden gets baking-hot sun.
The glaucous waxy coating that makes blue hostas look blue can melt in a very hot, sunny position. It certainly happened to a few of my hostas this crazy summer of 2010.
On the other hand, how’s this for blue foliage! This unknown variety of red cabbage is so blue, the leaves look almost metallic. And why not use edible plants as ornamentals, especially when they’re as ornamental as this! As long as you don’t touch the leaves (never a good idea with powder-blue leaves, as it removes the “frosting”), the cabbage blueness might be more sun-resistant than a frosted hosta.
Like the taro and rainbow “front chard” we showed you in Vivian Reiss’s garden, useful things like vegetables have their own beauty. How about it? What edible ornamentals are your favourites?
