Last year at the end of the summer, we dug out most of the Rose of Sharon trees in our garden (they are nothing but a big weed if you ask me)*, and I replaced the one at the front of the yard with this deep purple Butterfly Bush. I had seen them in a light lilac colour, but this darker colour was so beautiful I couldn't resist. When we planted it, it was a tiny shrub, maybe 2 feet high and 2 feet wide. It has almost tripled in size, and the more I dead-head it, the more it blooms. And does it ever live up to its name! There are almost always at least 2 or 3 butterflies on it whenever I look, and my favourite are the big Monarchs that swoop in like birds, and seem to dance around the flowers. I can't help to take a million photos!
*My amazing mother-in-law helped a huge amount, and it was no easy task - they are more like trees than shrubs. The roots were enormous! I think in all we pulled out 3 huge bushes, which left more than enough room for this bush, plus all our vegetables and some lavender.
