About this plant
A graceful salvia for late season colour, and a way to add airy height to sunny borders as summer begins to fade away. Fine stems are topped with clusters of blue flowers, which seem to float on the breeze. It flowers late summer through to the autumn, delighting the bees all the while. It can grow over a metre tall.

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 to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Spring - mid-late · Planting
Trim the plant
Trim the plant to give it a general tidy. This includes removing any lengthy or awkward shoots that make the plant look visually less attractive. Remove any spent flower heads at the same time.
Planting & general
Compost · Planting
Loam based compost + grit for repotting
Use a free draining loam based compost rather than one which has been modified to be 'moisture retentive'.
Alternatively prepare a compost using three parts of loam (John Innes no. 2 or 3) to one part of (horticultural) sand or fine (horticultural) grit.
