purpurea
means purple and refers to the
most common corolla colour.
This
shrub is best characterised from its whorl and bracteoles.
The more compact plants in cultivation seem to suffer from
bad suckering and those that don’t sucker tend to be rather
lax in growing, benefiting from being grown amongst other
shrubs for support. Careful selection from the wild of a
good growing form with a good pink colour is a priority.
The species is very variable in the wild, with leaves from
green to grey and flower colour from deep purple through
pink to white. Some of the forms distributed in commerce
seem to suffer tip damage from sub-zero temperatures in
our gardens. Greatly benefits from being cut back
regularly.
Branching lax evergreen shrub to 2 m. high (more
commonly around 1 m. ). Lower leaf laminas green through
grey to khaki, ovate, lanceolate or oblong with truncate
or cordate base, entire or crenate at margin, 4-10(–14)
× 0.7-5(-6.5) cm; petiole to 5cm. Floral leaves greener
than lower leaves , lanceolate, 4-7 cm by 1-2 cm; petiole
0.5-1.2 cm. Flowering stems simple or branched, bearing
up to 5 whorls per stem, each with up to 12 flowers. Whorls
4-5 cm across. Bracteoles lanceolate or elliptic, acuminate,
10-18 × 3-5 mm, adpressed. Calyx to 16 mm, 10 veins, with
teeth to 6 mm and a mucro 2-4 mm. Corolla 23-26 mm, purple
with lower lip sometimes almost white. Nutlets hairless
or with very short glandular hairs. Hardy to -10°C.

green leaf, P. purpurea ‘Green leaf’

(Pau) Losa & Rivas Goday ex Rivas Martínez
Acta Bot. Malacitana 2:61 (1976)
Synonym: P. purpurea Linnaeus var. almeriensis
Pau Distribution in the wild: Spain (Almería, Granada).
This
subspecies has generally narrower and smaller grey leaves
(4-9 × 0.7-3 cm) than P. purpurea var. purpurea
and is found in the Almería region of Spain. Calyx teeth
with mucros to 1mm, occasionally 2mm, but much less than
in P. purpurea var. purpurea.
P. purpurea Linnaeus subsp. caballeroi (Pau) Rivas Martínez Acta
Bot. Malacitana 2:61 (1976)
Synonym:P. caballeroi Pau
Distribution in the wild: Algeria &
Morocco.
Described
as being from Almería (Spain), and also mentioned in the
province of Alicante in Spain. Rivas Goday and Rivas Martínez
(1969) began to doubt its presence in Almería. Mateu (1986)
has never found living material attributable to this taxon
in Spain.
The
descriptions say that the upper leaf surface is greenish
and almost hairless in this subspecies. Calyx mucros very
small and hidden in the indumentum.
Two
varieties of P. caballeroi, var. montana and
var. submontana have been reported by Pau and Font
Quer from Morocco.
