Cultivation:
These
mountainous plants have thick
taproots
and are
susceptible to
overwatering.
They
loves a very
permeable, coarse
mineral soil as well as to be strictly
kept dry throughout the
winter quiescent period since it is very
sensitive to any
moisture excesses, To prevent
rottenness it is also advisable to surround its
root neck by very rough
sand or
grit, this help a fast water
drainage. They requires also an appropriate
air circulation and are sometime grafted
to avoid root problems. They need to be
kept in a cool place during winter rest (at 0-10°C).
This is important for the
flowers ,as well as for their health.
Without this cool winter period,
they normally won't get any buds.
Grafted plants are very easy to grow, and
are quite frost hardy (-5° C) if kept dry.
Needs a full
sun exposure ( light shadow my be useful in the hottest summer days)
Propagation: Seed,
cutting,
grafting
