This evergreen makes a large shrub or small tree. It is a hybrid of H. angustifolia & probably lyallii. It has very dainty leaves & forms an elegant slender plant. From mid summer it hangs with masses of round white flowers.
It should be more widely grown as it thrives in any good soil, in sun or part shade.
Tip: use for an unusual hedge, plant 1m apart. Trim after flowering.
