Germinate February to July at 20-30C (68-86F) on the surface of a good free draining, damp seed compost. Do not cover seed. Place in a propagator or seal container inside a polythene bag until after germination which usually takes 21-100 days. Do not exclude light at any stage, as this helps germination.
Transplant seedlings when large enough to handle into trays or 7.5cm (3in) pots. Grow on in cooler, well lit conditions for 10-15 days before planting out after all risk of frost, 30cm(12in) apart.

Aster Composition Height
By Alya Alvey 22-10-2013
In February 2013 I bought the package from T&M. Out of 60 seeds i have got 25 aster seedlings. They all are now flowering beautifully..Stunning display. They are all tall needing support. They are all between 70cm and 90cm tall. I wish I had some growing to 20 cm. I am looking for dwarf alpine perennial asters. if you have got them and are truly sure that they are dwarf would you please let me have some.
