A single Goatsbeard (Aruncus dioicus) goes a long way. It’s a big plant – ours grows about 5 feet tall with a 4 foot spread. It’s a perennial but looks more like a small shrub. But if you have the space in a spot that’s moist and shady, this plant has a lot to offer. It makes a frothy splash in June, after most woodland flowers are just a memory.


Goatsbeard is native to most of the Midwest and Upper South. The genus name actually means goat’s beard in Greek. Another common name is Bride’s Feathers, which makes me wonder what kind of brides wear feathers, and what kind of feathers do they wear?


Goatsbeard can get floppy after a hard rain. Some people cut it back in May to keep it more compact and upright, but I haven’t tried that yet.

The other day I saw several Dusky Azure butterflies fluttering around the Goatsbeard flowers. Turns out Goatsbeard is a host plant for Dusky Azures. I got this picture with my phone – the light’s a little off, but you can see what a Dusky Azure looks like. Tiny things but pretty. Now I’m going to have to search for their caterpillars.


Goatsbeard reminds me of the story The Three Billy Goats Gruff (“Who’s that clip-clopping across my bridge?”), which decades ago I enjoyed reading to my kids. We have a Dwarf Goatsbeard in the garden – the non-native A. aethusifolius. So I decided to get a middle-sized Billy Goat Gruff, this one in metal poking out from behind the Purple-Flowering Raspberry (Rubus odoratus).


Once we had all three Billy Goats, naturally we needed a bridge and a troll.

Have you tried growing Goatsbeard in your garden?

  1. I have the regular goat’s beard on the west side of the house, where it gets really hot. It has never gotten more than3 1/2′ high, but it’s really wide. It seeded a baby in a bad place, so that will go on the east side, where it will be under the trees and in shade pretty much all day. Be interesting to see the difference in growth habits.

    I also have the dwarf, and it’s stayed tiny. It is big enough to divide, though. It is just the cutest thing!

  2. I planted 3 goatsbeard in 2017 and they are growing nicely in a very difficult spot in my garden–about 3′ tall now. I’m so happy to learn that they are a host plant for a butterfly. I don’t think I’ve seen a Dusky Azure hovering around but I’ll watch for them now.

  3. I do love the goatsbeard, such frothy flowers. The Dusky Azure butterfly is just delightful, so delicate, I do hope you find caterpillas. I am enjoying the Billy goat grugg, the bridge and the troll, must set something like that up for grandbabe.xxx

  4. I love goatsbeard and currently have three in my garden. The one at the back of the house is partially under the dripline from the roof, and I need to stake it so that it doesn’t get bent down to the ground in heavy rain. I have one male plant and one female, and one volunteer seedling that showed up a few years ago and is currently planted in my holding area awaiting a suitable permanent place in the garden.
