About this plant
A rather beautiful, if undisciplined plant. This has short side branches carrying small silver-green leaves with scalloped edges, densely held and frothy in their effect. The plant tends to loll, or even lie down and does best with discreet support. It has delicate flowering stems that carry tiny blue-violet flowers and which appear in late summer and autumn. The grey stems remain a feature during winter. This plant originates in Turkestan and presents a wild and appealing appearance, though not perhaps for the tidy-minded.

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.
Spring - early · Planting
Prune hard to the base
Prune back to within 30cm to 45cm of the plant base so that the year's growth will begin from this low framework. If you want the plant to grow larger, this need only be done every few years.
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.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
