The title sounds like the name of a 1960s pop group, but this is all about my plant of THIS week - Joe Pye Weed.
It's a perennial, native to eastern USA, and grows to six foot or more high, with these architectural purple stems and deep pink clusters of small flowers. It is apparently named after an Indian healer who used the plant in his potions.
And you'll have noticed that last weekend I managed to photograph a butterfly happily feeding on it, in this case Holly Blue, but I also saw Gatekeeper, Common Blue, Small Copper and Meadow Brown feeding avidly on it too.
Because of its height, it is one for the back of a border, and it will need a good, moisture-retentive soil or it will struggle in dry periods. but if you have the space, it's a real winner for Honeybees and bumblebees too.
Oh, and the Latin name if you want to find it in your garden centre? Eupatorium purpureum. And from that you might notice the link with one of my favourite native plants for wildlife. Yes, this is the American (and hence rather showier) cousin of Eupatorium cannabinum, also known as Hemp-agrimony.
It looks great and with the added extra of being beneficial to butterflies and other insects. I will try to find a space for it. I already have Hemp-agrimony which does attract loads of insects.
