May be collected as:
Collection restrictions or guidelines
Careful! Alpine plants can be delicate!
Seed germination (needs dormancy breaking?)
Seed life (can be stored, short shelf-life, long shelf-life)
Recommended seed storage conditions
Propagation recommendations (plant seeds, vegetative parts, cuttings, etc.)
Propagates easily from seed.
Soil or medium requirements (inoculum necessary?)
Needs a sandy, acidic, well drained soil.
Installation form (form, potential for successful outcomes, cost)
Best if used in a rock garden with other alpine flowering plants. While propagation from seed would be cheaper, the success of transplanting a 1gallon specimen would be better.
1 gallon - $6.99
Seed Packets $3 from http://www.hillkeep.ca/2001_seed_list.htm
Recommended planting density
No more than 16 inches, in perfect conditions P. davidsonii only will reach about a 1 ft diameter.
