Friday Fabulous Flower - Pale blue Aster


Amid the many SYCs of fall, a few fall flowering plants of different color are a welcome relief.  Technically this aster flowers in late summer, the first two weeks of September over the past 5 years. 
The pale blue aster, Aster laevis, is a tall (4-5 foot) plant with lots of 1 inch diameter flowering heads.  The ray flowers are that type of blue that never seems right when photographed, and the disk flowers are yellow, which are still in bud on some of these heads and have flowered or are in flower on the others.  They don't look very big but butterflies seem to love this plant, which is sort of a bonus.  It does tend to reseed itself, so unwanted seedlings must be relocated or removed in the spring.  As a tall thin plant a bit of support is necessary if not surrounded by other tall vegetation.

Friday Fabulous Flower - Smooth blue Aster


Mrs. Phactor has done pretty well at getting more fall color into her perennial flower beds. Growing together in the center of one bed are two "blue asters" that are easy to confuse with each other. This species is taller and has larger flowering heads, Aster laevis, the smooth blue aster. Is the aster smooth and blue, or is smooth blue a particular hue?  The former it would seem as the leaves and stems are hairless and sort of a bluish green.  In a mass the flower heads, only about 1" in diameter, are quite handsome. Growing to over 1 m tall, they tend to be rather floppy, but maybe they would be better if grown among other flowers and grasses of similar stature.  Missed Friday last week completely so this is late not early.
