    Ruby-red smooth hydrangea!

    The dark burgundy red flower buds of Invincibelle Ruby open to a two-toned combination of bright ruby red and silvery pink. The foliage is extra dark and stems are strong, making this new hydrangea a gem in any garden. It is a strong rebloomer that will be an excellent addition to any garden. Like other smooth hydrangeas, it flowers on new growth and so blooms every year without fail.

    Maintenance Notes: 

    For the biggest, most abundant blooms and strongest stems, plant where it gets at least six hours of sun each day (warmer climates can get away with a bit less). A good layer of shredded bark mulch helps minimize water loss.

    As for pruning, cut the entire plant back by about one-third its total height each spring, just as the new growth begins to emerge on stems. This serves to build up a strong, supportive, woody base while also encouraging abundant new growth for plenty of flowers.

    If you wish to fertilize, an application of a rose fertilizer in early spring, once the soil has thawed, is sufficient.
