Plant Information

"Symphyotrichum laeve (formerly Aster laevis) is a flowering plant native to Canada, the United States, and Coahuila (Mexico). It has the common names of smooth blue aster, smooth aster, smooth-leaved aster, glaucous Michaelmas-daisy and glaucous aster.

The flower heads are arranged in clusters (panicles). Each flower head has 13 to 23 ray florets with pale to dark blue or purple petals (laminae), and 19 to 33 disc florets that start out yellow and eventually turn purplish-red. The whole flowerhead measures 13 to 25 millimeters (1⁄2 to 1 in) across.

Symphyotrichum laeve varieties are native to Canada, the United States, and Coahuila (Mexico).

S. laeve grows in fields, open woods, and along roadsides in rocky or dry soil and full sun.

Symphyotrichum laeve blooms in late summer and early fall. It is pollinated by many native bees and attracts butterflies. It is a larval host for the pearl crescent butterfly (Phyciodes tharos)."

stratification code
A

A	Seed should germinate when sown in a warm location.
B	Hot water treatment: Bring water to a boil, remove from heat, pour over seeds, and soak for 24 hours.. Generally this is for seed with a thick seedcoat.
C	(# of days of cold moist stratification) Seeds germinate after a period of cold, moist stratification. Mix seeds with a handful of damp vermiculite or clean sand (moist—but not wet). Place mixture in a sealed plastic bag and store in a refrigerator, NOT the freezer.
D	Sow on the surface of the soil. Generally these seeds are very small.
E	These seeds need a 60-90 day warm, moist period followed by a 60-90 day cold, moist period.
F	These seeds need a 60-90 day cold, moist period followed by a 60-90 day warm, moist period followed by a 2nd cold, 60-90 day moist period.
G	Highest germination rate in cool soil.
H	Seeds need scarification: One way this can be achieved is to rub the seed between two sheets of sand paper. If code "C" is also called for, scarify first.
I	Legume Inoculant (more info next year).
J	Legume seeds (more info next year).
K	Parasitic species which needs a host plant.
L	Plant fresh seed or keep seed moist.
M	Best results when seed sown outdoors in the fall for a natural winter.
