The green alkanet is beautiful right now (I took these photos this morning). Unfortuantlely someone recently wrote in a major UK newspaper about its summer flowers. I wouldn't take advice from them - it flowers in the spring! It's great because it flowers before other flowers and it's wilted by the time other flowers are blooming so it's perfectly timed. Also the bees love them - and there's not much in bloom right now.
While I'm talking about misinformation, green alkanet is often misnamed as borage. I hate blog writers who do that and then have no mechanism to be contacted to let them know, ie no email address.
