Hydrangea involucrata 'Plena'

Bracted Hyrdangea

Plant Type:


Hydrangea involucrata 'Plena' – Serrated petals on this double green-pink form – each floret with pink-tinted double sepals upon flowering mature with an increasing infusion of green over a long period, from July to October. Each inflorescence is delicate and lovely. In an odd way they remind me of those spinning carnival rides of gated seats up in the air built for two going round and round and round. When at peak there is a purity in the flower of pristine white blending with a refined pastel pink that is just so delicate and beautiful. Bold opposite foliage is dark green to blue-green in a very fine fuzzy, almost feeling felted, in a matte finish. This is a really beautiful plant. Fertile, humus enriched soil is a requirement for all Bracted Hydrangeas. Site in part shade. Cutting grown. Best suited for warmer climates. For the northern zones where it may thrive spring planting is strongly advised.
