Hydrangea arborescens 'Invincibelle Sublime™' (PP34,418 'SMNHRL')
Hydrangea arborescens / Smooth Hydrangea is a versatile and resilient shrub that brings elegant blooms to your landscape with stunning summer and autumn color. They excel as mass plantings or individual specimens in partial shade in mixed borders, woodland settings, as a low hedge, or as backdrop for perennial gardens. Their blooms offer winter interest when left on and make excellent cut or dried flowers for indoor arrangements.
For Hydrangea arborescens, a minimum of four hours of sun is recommended for best flower color and stem strength. Can grow in full sun in cooler climates, but afternoon shade is recommended in hot areas. In all areas, a good 2-3" layer of shredded bark mulch is recommended to keep the roots cool and growing vigorously. Prune in early spring, just as the new growth begins to emerge. Cut back by no more than one-third the total height. Cutting back more may hinder the development of strong stems. Can also be pruned in fall, once the plant has gone completely dormant. Deadheading is not necessary for continued bloom. Cut blooms to enjoy indoors.
Our plants are grown in 3.5x3.5x4” plantable pots. Made from 100% biodegradable coconut husk fibers (coir), these pots have tremendous advantages over plastic pots. With better air exchange, this "breathable" pot fosters robust root growth and reduces transplant shock since you can plant the pots directly in the ground. The pot naturally becomes part of the soil on its own over time—no composting required—and since they're made from a renewable resource that requires very little energy, they're earth-friendly too!
