Gardeners' Notes:


On Sep 30, 2010, kentstar from Ravenna, OH (Zone 5b) wrote:

Very lovely rich purple petals with a golden center. You must pinch back mid-June to early July to delay the bloomtime until late summer/early falltime. You must also keep watering from the base if possible, and spray something like Bayer Disease Control a few times during summer to protect it against mildew and such. Otherwise, is very easy to care for, loves a moist site in full sun to part shade, and blooms it's head off! Next spring, I wil try to find some short pink annual to plant right in front of the bases of the plants, as their legs get ugly later on.

Nice color but the several I've grown get decimated late each summer by either lacebugs or mites. They manage to survive but they look pretty sad just as the blooms finish peaking. I like 'Sapphire' and 'Prof. Kippenburg' better.

MG & Nursery Owner told me that this cultivar spontaneously developed in a garden in Allentown, Pennsylvania: right here in the Lehigh Valley!
***Disclaimer: This is hearsay. I'm playing "Whisper-Down the Alley" on the internet. I think story is cool & source is decent.***

- Survived tough winter in 10" pot. Beautiful flowers. Even more beautiful with space to spread!
- Prolific seeder. Damp weather wrecks seed heads. Watch for mildew.
- Prone to root rot/wilt. Needs good drainage.
- Disliked being divided midsummer & in fall. Perhaps can only be divided early spring???

A hardy native but I've had to hide them behind other plants to mask the bottom half, which turns brown and nearly defoliates by the fall. Otherwise beautiful flowers atop a very unattractive base.

This plant was given to me by a gardening friend in CT. It was a division from her own garden. I have had it for a number of years now and have not found it to reseed itself like my tall NE asters do. But it does spread vegetatively quite well. It has been divided a number of times and passed along to friends and relatives. I also find that the bees are not attracted to it at all, compared to how they swarm the taller NE asters. Aside from that, it is wonderfully floriferous, strong growing and to me the best thing about it is that it is of shorter stature, around 24 inches in my garden, which makes it wonderful towards the front of the border/bed. I recommend it!

Originally native over a wide area of the eastern and central USA, this species is represented in cultivation by many cultivars, showing much variation in form and color of blooms. Vigorous clumps of mostly vertical, 3-5' stems are likely to lean with the weight of large, loose clusters of daisies, making staking necessary. Cultivars include the late-bloomimg, clear pink 'Harrington's Pink'; the rose-pink, mildew resistant 'Barr's Pink'; and the cerise 'September Ruby''; while 'Andenken an Alma Potschke', is a compact-growing, though 4' tall plant with bright rose pink blooms, and 'Hella Lacy'. These asters prefer a moist, rich soil in full sun.

New England Aster "Purple Dome". Grew in a container on my sixth floor balcony in Denver from three small plants planted in June 07. My photo is from 10/11/07.

ASTER PURPLE DOME - New England Aster - Medium - Plant 20" apart. - Only 18" high. Compact and free flowering. A stunning, deep purple. Disease resistant. We are happy to be able to offer these fine New England Asters. They form robust semi-woody clumps which flower from late summer into fall. And do they flower! Each arching branch is covered with blossoms. Tolerant of wet conditions .

I have it in my garden, having bought it locally in 2005. This year the wild rabbits chew alot on it, but finally left it alone and it got bigger again and bloomed. It is beautiful! I hope they leave it alone next year and it gets even more beautful with alot more blooms. I might have to sprinkle some cayenne pepper on the leaves in Spring to get them to leave it alone.


This year in Spring and early Summer, I sprinkled some cayenne pepper on the leaves (and after any rainfall), hoping the wild rabbits would leave it alone, then I pinched it every so often and it ended up looking like the photo I posted on 10/13/07.

This is my first experience with the 'Purple Dome' Aster and it's been quite a success. I started with tiny plants from mailorder that I didn't expect would grow much the first season. I ended the season with well behaved (no flopiness, here!) neat plants with close to mature spread and covered with a multitude of blooms.

The plants are growing in sandy soil in a location that gets some afternoon shade. My main problem with these particular plants is that rabbits tend to enjoy nipping off the new growth. "Rabbit-no-more" repellent worked very well as long I remembered to refresh the application after we had rain.

I was very impressed with 'Purple Dome' aster...and plan to add more to my gardens.

This aster has beautiful vivid purple daisy-like flowers that cover the plant. They are 1-2 wide with a plant width of 18-24 and a height of 18. Gprgeous!!!

It blooms in the early fall till frost and is a definite butterfly and bird attractor.

Purple Domes looks great in borders and mass plantings.
