Walker's Low' has attractive colouring, the flowers being quite a deep blue-mauve, the leaves silvery and aromatic, and the stems dark. Comes into flower in early summer, and will continue into autumn if flushes are deadheaded. It is variable in habit according to growing conditions, and can make a tight mound to 60cm in height in poor soils, or in richer ground grow to 90cm and be more sprawling.
All our plants are supplied in at least 9x10cm pots. Plants in this size pot establish quickly in the garden and often outpace plants planted in bigger pots at the same time. We do not sell 'plug plants' because those need to be grown on before planting. Our potted plants can be planted immediately, unless otherwise noted, or you can leave them in their pots until you are ready to plant. We grow everything we sell ourselves, in our nursery in the Buckinghamshire countryside.
