Mountain Hydrangea

'Tuff Stuff Top Fun' hydrangea’s bold lacecap blooms are supported by bright burgundy stems. Each flower is filled with soft green fertile florets at the center and purple or pink infertile florets around the edges. Lacecap hydrangeas are very inviting to pollinators and make lovely cut flowers. It is a strong bloomer with flowers produced all summer long, first on old wood and later on new wood. Bloom colour will depend on soil chemistry.

Growing and Maintenance Tips

Serrata amd mactophylla type hydrangeas should be planted in moist well drained soil with the addition of lots of organic material. A mulch to conserve moisture is recommended. They need direct sun but prefer protection from hot mid day sun and can burn in hot dry conditions.  Pruning is not necessary and will affect flowering. although dead or damaged branches should be removed in the spring. The "default" colour for big-leaf hydrangeas tends to the pink/red tones, and that is the color they will display in neutral (pH 7.0) or higher soil. The soil must be acidic for the blue color to develop. Aluminum sulfate can be applied in late winter or early spring to acidify the sil if desired.
