2 x 2m. A lax evergreen shrub, bearing large semi-double yellow flowers in spring and early summer - and also, surprisingly, in autumn too in the last 2 years! Best grown against a sunny wall or fence. Has survived many hard frosts over the las 15+ years against a south-facing fence here in Hampshire!!
60 x 100cm. Upright, semi-evergreen, suckering shrub. Pretty pale violet flowers with yellow throats and purple spots in summer. Fertile, well-drained soil in part sun. Protect with a mulch in colder areas.
