Medicinal and aromatic plants – industrial profiles

L. x heterophylla
Poir.
A hybrid originating in cultivation between 
L. dentata
and 
L. angustifolia
. Similar in general
appearance to 
L. x allardii
, but it would appear to be a less vigorous plant and with much
smaller bracteoles which are obvious as in 
L. x allardii
. Many plants grown under this name are
probably 
L. x allardii
and this cross appears to be rare in cultivation. Further work is required to
confirm the identity of 
L. x heterophylla
.
L. dentata
L.
L. lanata
Boiss.
A bushy woody shrub to 75 cm. Leaves lanceolate to obovate with a dense silver grey indumen-
tum, the leaves entire or often toothed. Flower spikes conical in shape 6–10 cm with purple
mauve flowers. Bracts diamond shape, violet coloured at least when young, more or less becom-
ing sterile near apex of the spike and forming a small tuft of bracts (a coma) present, bracteoles
2–3 mm. Corolla deep violet-blue.
The cultivar ‘Goodwin Creek Grey’ selected and bred in the United States appears to be the
only cultivar available with this parentage.
