Invincibelle Wee White® Hydrangea is the first dwarf ‘Annabelle’ type hydrangea! Pure white mop-head flowers bloom from summer to fall, aging to shades of lime and pink atop sturdy stems. This shrub naturally grows as tidy, rounded mounded, and is a great plant where space is restricted!
Invincibelle Wee White® Hydrangea is a compact selection of Hydrangea arborescens that works well where large, showy flowers are desired. Low shrub borders, informal hedges, and foundation plantings are excellent areas where this plant can be massed. The long lasting blooms make great cut flowers and will maintain interest throughout the season.
The flower heads of Invincibelle Wee White® Hydrangea are not especially attractive to pollinators, especially when sited in shaded environments. For a hydrangea that will attract butterflies, consider using one that has more lacecap flowers like Quickfire® Hydrangea or Twist-n-Shout® Hydrangea.
Invincibelle Wee White® Hydrangea should receive annual Heading Cuts in spring once established. Remove a third of the plant with each pruning, cutting back to a lateral bud. If the plant is overgrowing its space, you can use Rejuvenative Pruning to maintain its compact habit.
This shrub is a rebloomer and does not require deadheading to encourage a second flush of flowers. However, spent flowers can be removed if you do not like their appearance.
Like all hydrangeas, Invincibelle Wee White® Hydrangea has shallow roots and does well with a maintained mulch layer in its bed. Stone mulch or shallow bark mulch will not protect these roots and make the plant more susceptible to injury. In periods of low rainfall, this shrub should receive supplemental watering to avoid scorch/scald when sited in full sun.
Invincibelle Wee White® Hydrangea has no serious insect or disease issues. In highly alkaline soils the leaves may develop chlorosis, but the plant is adaptable to a wide range of soil pH and texture. In periods of drought, the leaves may drop if the shrub is not given supplemental watering.
Occasionally, the shrub may develop bud blight, wilt, leaf spot, rust, or powdery mildew. These issues are usually minor and often resolve within a year. If foliar diseases are problematic, you can prune the affected stems. Make sure you dispose of cuttings away from the plant to avoid reinfection.
Aphids, mites, and scale are also known to attack the plant. While these pests are not of major concern, heavy infestations can reduce plant vigor. Aphids and mites can be treated with an insecticidal soap that kills the insects on contact. Scale insects should be managed using a dormant oil that will suffocate the juvenile insects when they are active.
Invincibelle Wee White® Hydrangea is a compact selection of Annabelle Hydrangea, known for its massive white mop head flowers. Where Annabelle is too large, Invincibelle Wee White® Hydrangea is an excellent substitute and will succeed in a variety of landscape uses. Its compact habit reduces the likelihood for the heavy flowers to flop and generally does not need staking. While this shrub will tolerate partial shade, the sturdiest stems are produced when the shrub is sited in full sun. The flowers take on shades of pink and lime green as they age, but this coloration is not as pronounced as Hydrangea macrophylla and Hydrangea paniculata cultivars.
Invincebelle Wee White® Hydrangea is a selection of Hydrangea arborescens, a species native to the eastern and southern United States. It is known by the common names Smooth Hydrangea, Wild Hydrangea, and Sevenbark, which comes from the shrub’s exfoliating bark. In the wild, Sevenbark is found on wooded slopes or streambanks. Occasionally the shrub can grow to a height of 10 feet in its native range.
Invincibelle Wee White® Hydrangea can be paired with Invincibelle Mini Mauvette® Hydrangea for varied blooms. Use perennials and shrubs of varying textures and colors to contrast the form of Invincibelle Wee White® Hydrangea. In sun, use Little Devil™ Ninebark or St. John’s Wort. With less sunny sites, use shrubs like Yuki Cherry Blossom® Deutzia or Jewell Bush-honeysuckle.
