or partially toothed with 1–7 teeth on each side above the centre and towards the apex. Both
leaves and stems grey-green. Flower spikes long and narrow, 7–12 cm, often interrupted. Each
cyme has 7–9(–11) flowers, bracteoles present. Bracts broadly ovate-lanceolate, tapering to 
a sharp apex and with no coloured bracts borne at apex of spike as in one parent 
L. dentata
.
Corolla shades of blue.
A sterile hybrid that originated in cultivation between 
L. dentata
and 
L. latifolia
. Flowers over
a long period June–September in the United Kingdom. Not fully hardy only surviving a few
degrees of frost. In frost-free areas it can make a good hedging plant and imposing specimen. 
A number of different clones appear to be in cultivation some of which have been named:
‘African Pride’ – common in South Africa with occasionally toothed foliage; Clone B – refers to
material from Australia with mainly toothed foliage.
