About this plant
A low growing, spreading plant that has beautiful foliage. The broad leaves are a soft silvered green with a matt surface, netted by fine veins and hairy on their upper surface. They are pleasantly aromatic as well. The columnar flowering spikes a coloured pale blue with violet stems. It is by nature a plant that will sucker and could be used in a container or could cover a large bed. It is not frost hardy but can be used for summer bedding, perhaps over an area adjacent to seating where its beauty and aromatic foliage can be appreciated.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
Spring - late · Planting
Divide when too large
When the plant is too large clumps may be divided into two or more pieces. Rhizomes can be cut, whilst small bulbs or offsets are detached. The new plants can be grown in a container or planted in the ground.
