recommendations (plant seeds, vegetative parts, cuttings, etc.)
Increase by
division early in spring by root cuttings or by stem cuttings taken with a bit
of rootstock at the base of the shoot.
Soil
or medium requirements (inoculum necessary?)
Open,
quick-draining, but moisture retentive soils of moderate fertility and a
neutral Ph will work fine for most mountain plants that can be found in drier
mountain slopes.
Installation form
(form, potential for successful outcomes, cost)
Unknown
Recommended
planting density
Prefers to be
planted in small crevices
Care requirements
after installed (water weekly, water once etc.)
