A hybrid between P. myrtifolia and P. oppositifolia, I've found this to be a very rewarding small shrub (up to 1.5m) for growing in the milder coastal regions of southern England.

Parentage P. myrtifolia var grandiflora x fruticosa var. cordata

Erect, rounded evergreen shrub, has ovate or lance shaped, glaucous, mid-deep green leaves 1 inch long and can be alternate or opposite on the same plant. Bears leafy, terminal racemes of light purple or deep rose pink flowers with fringed keel.

Flowers all summer and into autumn.

Minimum temperature 42F.

Needs shade from hot sun. Monthly balanced liquid fertiliser when in growth, a loamless potting compost and good ventilation is required.

Aphids and whitefly can be a problem to this plant.
