I have always loved Ageratum, but have been unable to keep it looking good for any period of time. By mid-summer, they are a mess, I cry and vow to never put myself through that ordeal again. Fool me once …
Lo and behold, one day I was googling “Ageratum” thinking I could unlock the secret to keeping this annual alive all summer and found a plant claiming to be a perennial Ageratum. What? Has someone been reading my diary?
Dreams do come true.
But it gets better. This plant prefers a wet site. And is deer resistant.
Hardy Ageratum? I’m like totally in.
- 18” x 18”
- Blooms in mid-summer, early August here in zone 6B
- Requires full sun
- Survives zone 5-8
- Deer resistant
- Very tolerant of a wet site
- Very slow to emerge in spring, one of the last to show signs of life
- Great winter interest with the spent flowers
- U.S. native
- Has recently been reclassified as Eutrochium
As mentioned above, this plant is slow to emerge in spring and I’ve actually forgotten about it until it finally emerged sometime in late April. Another reason to not cut down those perennials too soon people. The spent flowers/stems are a much needed reminder of what is what in my ever expanding jumble of a garden in spring.
I’ve noticed that my original five purchased have expanded a bit in year two as this plant appears to reseed some. It is too soon to say if it is TOC (Totally Out of Control, for those without young kids) or if the reseeding is a must because this perennial is short lived. That is what I’ll be keeping my eye on this year.
The blooms start to develop in July and are a welcome site and color, as we proceed through the dog days of summer.
Within a week or so, the blooms fully emerge and they are quite stunning in my humble opinion.
The blooms are so interesting up close that I’ve taken to capturing them on my camera phone, macro style.
But the interest in the blooms doesn’t end there. As the purple/blue flowers fade with the arrival of cooler weather, they remain interesting into the colder months.
Here in October, fluffy seed heads looking right in place with the gold and red hues of autumn.
And especially handsome when covered in frost.
