Diascias for me start off with a
distinct advantage in that they belong to the Scrofulariaceae, which has
always been one of my favorite sounding plant families.
Diascias come from South Africa, from
mainly mountainous regions. They are very valuable in the perennial
garden for their long flowering season. Only able to be grown outdoors
all year round from zone 7 upwards.
In cooler climates, Diascias can be
overwintered successfully under some protection, a cool greenhouse is
ideal, as long as they don't get frost on them.
They are exceptionally floriferous in
quantity and also in length of season. Grow in full sun and dead head
regularly, water in exceptionally dry spells. Easy to propagate from
cutting in the spring or early summer.
