About this plant
This makes a bright silver-grey tangle of upright and arching foliage. The leaves are large with variably-shaped leaflets standing out from the sturdy midrib. They are individually striking and could be used as a foliage component in a flower arrangement. The plant is summer-flowering with strong pink blooms. If required solely for its foliage contribution these could be removed. In the garden this solid-effect plant could be a good foil for tangy citrus tints.

Spring
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Summer
Summer - early · Outdoors
Feed a general fertiliser
Where plants have moderate needs for nutrients, they can simply be given a general feed, fairly early in the growth season so that the growth has plenty of time to harden off before the cold weather.
Give plants a general boost with the application of a general purpose fertiliser which is spread around the root area of the plant, with amounts as directed on the feed label.
