Prime White has been selected from seedlings of Hydrangea paniculata 'Dharuma'. Flowering on the previous year's growth, the shrub is very early flowering from the end of May or June (depending on the region), producing elegant white, slightly flat flower panicles. The abundant sterile flowers have large sepals which start cream-coloured then turn white. In good conditions a second flowering prolongs its decorative interest in August - September..
This small plant with fine grey-green wood, pale green foliage and very red stalks remains small. Well branched, it has a more regular shape and better growth characteristics than its parent plant.
The different varieties of the Hydrangea paniculata range go well in a shrub border together with perennials or in a pot.
