Gardeners' Notes:

This is my second year with this plant in a sunny Colorado rock garden. The first year it had a bit of mildew coming straight out of an indoor garden center area but this year it has absolutely no issues, just beautiful, lots of blossoms, great purple color, nice size and hardy. Easy, low maintenance, great performer and very healthy! Water needs are easily satisfied, thrives without a fuzz and we had a drought this summer, record highs. I am very happy and hubby likes it too. Great purple color!

Let me start out by saying I have far from a green thumb when it comes to flower gardening however, these aster flowers - (Professor Kippenburg), are stunningly beautiful! OMGosh - they literally glow from the street. I planted the 3 of them in mid-April and by mid-September they are extremely full and lush. The petals are a light blue with a 'tinge' of purple and yellow centers. Couldn't be happier with them!

Short to Medium - Plant 16 - 18" apart. 10 - 14" in height and blooms beginning in September. Very durable and long lived. Watch for powdery mildew beginning in mid summer, but good air circulation will go a long way towards preventing disease. Pinch back and divide like mums for best display. Bright blue.
