plant to grow, but it is a winter grower that tends to produces new
leaves and stems in autumn and stops growing loosing its leaves
during the hottest and driest summer month. It is also a little low growing container
plant. As it grows, it produces side branches. Generally, give it
full sun (coastal) to light shade in well-drained soil. It enjoy more
water than others but do not over-water, drench and let dry between
waterings. Keep moderately dry in winter.
It may be grown outside in
mild climates.
