Wildflower Wednesday: Eupatorium purpureum

By late August our Georgia garden tends to be rather weary from the heat, humidity and lack of rain.  Most of our summer blooming perennials are past their peak and looking a bit worn, making Eupatorium purpureum a super star this time of year.

Commonly called Joe-Pye Weed, this herbaceous perennial is not a weed at all but a wonderful wildflower that is a favorite among many gardeners. Big and bold, growing up to 10 feet tall and 6 feet wide, it is a showstopper in moist meadows, native plant gardens and along roadsides. Eupatorium purpureum enhances our late summer, Zone 8 garden and transitions us seamlessly into fall. 

Joe-Pye is a must have plant for a butterfly garden rich in native wildflower diversity. It fills the gap when many summer species are done flowering thus providing a rich food source for the many pollinators that thrive in our habitat garden. The mauve, vanilla scented flowers entice the insects to visit, luring them in to their sweet nectar. It is especially loved by swallowtail and monarch butterflies. 

From the earliest morning light until the sun sets, Joe-Pye is blanketed in butterflies. It is an amazing sight to behold! Finding a monarch amongst the swallowtails is pure happiness. Monarchs are a rare sighting for us, particularly this time of year and we delight in their presence.

Eastern Tiger Swallowtails are abundant in our garden and as two of their host plants, tulip poplar and wild cherry tree, are plentiful in our woods it is only a short journey for the adult butterflies to the woodland edge ,where they can find a stand of Joe-Pye. 

The same holds true for the spicebush butterflies (host: sassafrass and spicebush) and black swallowtails (host: Carrot family-Apiaceae) who join the party, albeit not in such large numbers as the tiger swallowtails.

Diurnal moths, like this clearwing moth (aka hummingbird moth) dive right in to drink the sweet nectar.

Native bees such as leaf-cutters, diggers and bumblebees tumble industriously around the umbles. 

Other pollinators such as bee flies and skipper butterflies also frequently feed on the flowers.

If you don't already grow Eupatorium purpureum, I highly recommend this buffet for pollinators. I have found that it prefers part shade situation when in semi-moist soils, but does equally well in our full sun rain garden, where it benefits from more moisture. If you are concerned about the size of this native wildflower then try the dwarf variety 'Little Joe' (E. dubium). 

I'm joining Wildflower Wednesday host, Gail at Clay and Limestone. Be sure to blog hop to see other fabulous wildflower growers. 


  1. This is a wonderful plant for pollinators. I massed it out in a native garden design a couple of summers ago in a semi-shaded area and it thrived! Great post and very informative!

  2. So love this one! Great critter captures. It was so dry here that the Joes folded up shop early. Happy WW.

  3. This is so interesting. Generally, you seem to be ahead of us with blooming plants, but Joe Pye is long-faded by this time of year here in S. Wis. I tried to get some established, but my garden is too shady. So, I'll enjoy it in the wild, at the Arboretum, and on your blog post. :)

  4. Love seeing all the butterflies and other pollinators!
    Happy Wildflower Wednesday!

  5. Lucky you. I have searched all over east Texas for Joe Pye. Wonder if garden catalogs carry it?

  6. Wow! So many butterflies. I would love to have one of these!
    Thanks for sharing.

  7. Once upon a time I didn't really care for Joe-pye because I thought the blooms looked strange, but I've really fallen in love with this plant over time. The pollinators love it, and I like how tall it gets. Up here in the north it can take full sun, and it makes a great statement in the garden at the end of the summer. Love all your butterfly shots!

  8. Wow, great butterfly pics. I have some of the Sweet Joe Pye Weed - I like that it is shade tolerant and generally adaptable.

  9. Little Joe sounds good for the smaller gardens I am used to. What a wonderful host of happy butterflies you have!

  10. I love Joe Pye Weed! In July I planted several variegated ones called 'Pink Frost.' They are gorgeous and have been blooming almost two months. The pollinators are very attracted to them.
