Acidic fertilizer will not work on your Buddleias.....but the better the soil, the better the plant.....which may give you better looking flowers.

Black Swallowtail. Was it laying eggs? Or did it just eclose? Looks like it's on some parsely, which is a host plant.

Hmmm I haven't got any delphinium, you just added to my plant list Eric.....Isn't it neat to see them in a plant drinking nectar?

I can't remember where I bought mine, it was so long ago. It finally started dying back last year, so I dug up what was left. My husband was very sick, and I couldn't take care of my garden last spring or summer, so my vigorous passionvine, monarda and other plants overtook it. If I had weeded properly, it would probably still be growing. Still, I had it at least ten years. I Googled it and found MANY sources for it, ranging from $4.00 to $24.00. The nurseries that I do business with regularly aren't carrying it, so I can't recommend any of the nurseries. I ordered a butterfly bush called 'Inspired Violet' last year, grew it in the pot until I was sure all the butterflies liked it (they do) then planted it in its own bed. I got this one, even though I don't like the violet pink color as well as Ellen's Blue color, because it doesn't make seed. At my age, I'm trying to make gardening as easy as possible. Ellen's Blue does make seeds, you have to dead head a lot, but that's its only draw back. It's a wonderful size, and those LONG, nearly true blue blooms are to die for. Just Google Ellen's Blue butterfly bush, and take your pick, although I'd prefer to order it from a nursery as close to my home as possible, so it won't have to be in the truck too long. Sherry
