Uses in landscape design

Excellent at the coast as it tolerates salt-laden wind and short periods of drought. Also good for the shrub border in areas with moderate frost. Flowers attract butterflies.

Planting instructions

Planting: Not very fussy, but will benefit from fertile soil. Dig a hole 60cm square and deep. Mix two-thirds of the topsoil with one-third compost in the bottom of the hole, add one cup of bone meal or superphosphate and mix well.

Watering and feeding: Water when dry and feed during spring with a general fertiliser for flowering plants.
Pruning: Not necessary, but it can be pruned hard to promote bushy growth close to the ground. It can also be pruned and clipped into a standard shape.
