Hydrangea 'Incrediball’, the Tree Hydrangea (also known as Strong Annabelle), produces amazing and enormous colour-changing blooms that change from Lime Green to Pure White then fade to Green again, to make the most amazing displays in your garden and your home. It is unbelievable but true.

This is an entirely different species and variety than the traditional pink and blue plants you are probably more familiar with. The stems are incredibly strong to enable the support for this amazing flower, and they are tolerant of rain and wind hence the name, 'Incrediball'. Also known as 'Strong Annabelle', this has been bred to supersede Hydrangea 'Annabelle', which suffered from weaker stems in wind and rain.

Displays will be all summer long whatever the weather and will produce flowers up to 30cm or 12 inches in diameter. They can be cut and used as dried flowers too - this will preserve the natural colouration or spray them gold or silver for spectacular Christmas decorations.

The Tree hydrangea is a form of Hydrangea that is quick-growing, forming an upright shrub. Unlike the bushy hydrangeas, these shrubs provide later blooms for added garden colour. Growing as a shrub with multiple stems, tree hydrangeas can be pruned to look like trees, hence their name.

Supplied as an established plant in a 3L pot, for real Summer impact in your garden, the Tree Hydrangea 'Incrediball' is a winner.

Top Tips

Hydrangeas do not like to dry out. In dry weather, if your plant wilts, soak the roots with a hose and the plant will usually recover, and in any case, water regularly until plants are fully established.

Care Information

Planting Advice for Hydrangea Incrediball:

  • Really low maintenance, Incrediball prefers compost-enriched soil that stays moist. It can be planted in sun or light shade.
  • Shrub roots generally tend to spread out rather than down, so dig a planting hole 3 x wider than the roots of the shrub you're planting and mix some well-rotted compost or manure with the soil from the hole and use this to re-fill one the shrub is in place.
  • We've found that a square hole is better than a round one as the new roots, once they reach the edges tend to grow in a circle round the circumference of the hole whereas when they reach the corners of a square hole, they find it easier to grow through.
  • Before planting soak container-grown shrubs thoroughly and allow to drain.
  • Remove the plant from its pot and tease out a few of the roots.
  • Add Mycorrhizal fungi to the roots when planting to help plants establish quicker.
  • Place your shrub in the hole at the same level at the pot.
  • Refill the hole with the earth removed (backfilling) and firm in the soil with your heel, avoiding the root ball, then water well.
  • Mulch around the base of the plant with a collar, compost, gravel, bark etc.
  • If you're planting into pots, place some old rocks, stones or gravel in the bottom of the pot for drainage and ballast. Use the best compost you can buy and some sand or grit for drainage.

Care Advice for your tree hydrangea:

  • Because the flowers are white, they are unaffected by soil type.
  • Feed-in spring to encourage flowering, our Hydrangea feed is ideal.
  • Keep well-watered through the year.

 Pruning Advice for tree Hydrangea Incrediball:

  • As these hydrangea flowers on new wood, you can leave the faded hydrangea flower heads in place until the new buds begin to swell in spring – this also protects the new growth from frost damage.
  • Just cut back the stems to a strong pair of buds. Remove any branches that are damaged or dead as well as any that are misplaced.
  • After pruning hydrangeas, apply a mulch of well-rotted manure or compost around the base of the plant.
  • Once established, you can remove up to a third of the shoots to the base of the plant to encourage new stems.
