The white-throated flowers
grows up to 7 cm in diameter,
The E. pentalopus forma mostruosa
is usually found grafted on stronger stocks, but it grows quite well on its
own roots too. It needs good drainage, keep well
ventilated, as it is prone to
root rot. Protect from
freezes. Hates the full sun in summer.
Water regularly from March to October. It
should be kept in a cool place during winter rest (it
can briefly tolerate temp. as low as -7°C).
Without this cool winter period these plants normally won't get
many buds. Stems may
possibly become purple and limp in winter, but revitalize in early
spring. Feeding may not be necessary at all if the compost is fresh then, feed
in summer only if the plant hasn't been repotted recently. Do not feed
the plants from September onwards as this can cause lush growth which
can be fatal during the darker cold months.
Propagation: By vegetative propagation
grafting or stem cuttings from adult plants.
