Aster Purple In Plastic Pot.
Symphyotrichum patens, commonly known as late purple aster or spreading aster, is a perennial, herbaceous plant found in the eastern United States.
Planting And Care:
- The best time to put young aster plants in the ground is in mid- to late spring after danger of frost has passed.
- Or, you can plant mature, potted asters when they become available at garden centers (typically, in the late summer or early fall).
- Asters can be grown from seed, but germination can be uneven. If desired, plant seeds in the fall or start them indoors in the winter.Â
- When planting young aster plants outside in the spring, space them 1 to 3 feet apart, depending on the type and how large it’s expected to get.
- Fully-grown asters, such as those available in late summer or early fall, should be planted about 3 feet apart.
- If planting seeds, sow 1 inch deep in pots or flats and refrigerate them for 4 to 6 weeks to simulate winter dormancy. This cold period will kick-start germination.
