Gardeners' Notes:

This plant requires fertile soil and plenty of room to produce big leaves. It is best harvested by cutting leaves and buds before the flowers open. The stems are very tender and buttery tasting if harvested early but once the flowers open, the stems become tough and woody. Lightly sauteed and served with balsamic vinegar, the greens are delicious.

I grew this a couple of years and it was a very beautiful plant - long purple stems, graceful purple-veined leaves. But eating-wise there just wasn't much substance or flavor to it for me. The plant is mostly rather tough stem with very little leaf. Not much to eat for the square footage it takes up. It was very quick-growing and easy though.
