Product Description

Callistephus chinensis

 

 

 |100 Seeds|

 

 

Just when other flowers in the borders are about done, Aster Callistephus starts blooming in the latter part of summer and into the fall. This tall Unicom rose Aster is a lovely shade, and it grows on strong, upright plants that reach about 24 inches in height. The stems are sturdy and make these spider-like blooms great for cutting and arrangements. Blooms will last 6 - 8 days in the vase. Aster plants are not picky about soil types, but they do require full sun to partial shade to do their best. It is recommended to grow Aster flowers in a different location each summer to avoid disease.

Sow Indoors

  • Keep media moist and near saturation by watering before planting seed. Start 6-8 weeks before the last frost is expected.
  • Do not cover or bury the seed, just press lightly into the wet soil,  as Aster seeds needs light for germination.
  • Germination improves when you give the seed a cold treatment when seed is started indoors, place the seed in its seed tray outdoors at 40 degrees or in the refrigerator for 2-3 weeks. After cold treatment start indoors at a temperature of 72-76ºF. Germination should occur within 2-3 weeks.
  • If you have high lights or a greenhouse you can start 8 weeks before your last frost.
  • If you do not have high lights or a greenhouse you should start your seeds 12-14 weeks prior to your last frost.
  • You can transplant the seedlings when they have 4 true leaves 2-3 inches apart.
