Cultivar or Variety: Autumn Frost

Characteristics of Plant
12x24 inches.
Bag seedheads to capture ripening seed. Allow seedheads to dry on plants, remove and collect seeds. Properly cleaned, seed can be successfully stored.
Medium growth rate and average substance. Leaf color is medium blue-green and margin is pale yellow.
*
Hosta seedlings do not need a night time rest period, so if the lights are on 24/7, you will gain 3 ‑ 9 months of additional growth by the time they are set outside.

Germination Tips: Soil temperature plays an important role as to how long it will take the seed to sprout and whether the seed will sprout at all. Soil temperatures tend to run 5 to 10 degrees cooler than the air temperature in a room. In temperatures of 60° to 70°F (20°C), the germination time for hosta seed will be about two weeks. Cooler rooms will greatly increase the germination period.
