Gardeners' Notes:

Wonder is right! A lovely, floriferous plant which has bloomed beautifully for me the first season. The daisy-like blooms are about 2" round and tidy, in a nice soft purple shade. Seems unscathed by bugs and slugs. A keeper!

Have had two plants for two years, growing right next to Aster x frikartii 'Mönch'. Still can't tell the difference between 'Wunder von Stäfa' and 'Mönch'. 'Wunder von Stäfa' is said to be taller and a little lighter in flower color. If it turns out to have all the advantages of 'Mönch', I will say it is an exceptionally good perennial.
Now position the two cultivars at the front of perennial beds. Might be a bit too much competition for them further back. Like 'Mönch', always needs staking, but with perennials like these it is well worth the effort.

This plant is great.... very floriferous and very long blooming, flowered in my area from very early summer to fall, but the magnificent show of flowers is on summer. I want some more of these. The flowers are blue-violet with small yellow eyes. It grow 36 inches tall.

Medium - Plant 20" apart - An unusual plant. Rapidly developing into an airy mound as broad as it is tall, as much as 3 by 3' in rich soil. Covered with lavender-blue daisy flowers with a yellow center from July until a hard freeze. Normally not for extreme northern gardens, but worth a try with dependalbe snow cover. Very long blooming open mound of lavender blue.

Comes back bigger and better year after year, needs very little in the way of care, mingles well with its neighbors....A really nice plant all the way around!

My asters have failed to take hold both years I've tried them. Will try to give less water and start earlier on the next attempt.
