Hydrangea arborescens Incrediball® 'Stormproof'®
sevenbark
Big, bold flower heads are the star of the show here, but it’s the sturdy growth that makes this hydrangea particularly useful. Hydrangea arborescens 'Stormproof' forms a more compact, well-branched shrub, with exceptionally strong stems at maturity that help keep its impressive blooms upright through summer weather.
From early summer, huge rounded flower heads emerge with a fresh green tinge before gradually turning clean white, creating a striking display against the foliage. Packed with nectar-rich florets, the blooms are also useful to pollinators, while the robust habit means there’s far less need for staking.
An excellent and weather-resisitant choice for borders where you want plenty of flower power without a shrub that takes over.

How to care for Hydrangea arborescens Incrediball® Stormproof®:
Choose a spot with partial shade to full sun, though at hotter, sunnier times of the year, partial shade is preferable to protect the blooms and avoid the plant wilting after planting. The soil should be well-drained, rich, and consistently moist, but not waterlogged.
Dig a hole twice the width of the root ball and just as deep, then mix in plenty of organic matter such as compost or well-rotted manure. Place the plant in the hole, backfill with the enriched soil, and water thoroughly. Mulch around the base to retain moisture and keep the roots cool, but keep the mulch away from the stem to prevent rot.
Regular watering is important, especially during dry spells, to ensure the plant establishes well and produces abundant blooms - hydrangeas do not like to dry out. Remove faded flowerheads in spring after the danger of frosts, cutting back the flowered stems to a strong pair of buds. Take out misplaced or diseased shoots.
Once established, remove a quarter to a third of the shoots to the base of the plant.
