HARDY PERENNIALS: LAMIUM

The main virtue of L. maculatum and L. galeob-dolon is that they will grow in shade, even if dry. The former makes a rapid spread 6 inches or so above ground with deadnettle leaves which are heavily spotted a paler grey-green. The flowers come on 8-9 inches stumpy spikes in spring, in white, purplish and pink, and L. ^Chequers’ is about the most colourful and compact variety. L. galeobdolon variegatum spreads quickly from runners and the leaves are in a bicolor variegation. Flowers are yellow in May, soon over, but in general these are easy plants for the more difficult places. L. garganlcum is much more choice, making a compact evergreen mound of light green and a long succession of deep pink flowers. Whilst L. orvala has erect spikes almost 2 feet high in May-June, deep pink in colour and quite showy, but dying away to a dormant slow growing root in winter. These last two species need shade, in soil that does not dry out but can be increased by division.
