In the garden
Hydrangea macrophylla Hi Tornado ('Hitor'PBR) belongs to the Hydrangeaceae and traces its ancestry to the bigleaf hydrangeas of Japan. As a deciduous shrub it produces the large, rounded flowerheads associated with H. macrophylla, with blooms that present in pink or blue tones and appear during the period June to September. Site the plant in full sun or partial shade; morning sun with afternoon shade suits many UK gardens. It prefers loam or clay soils that remain moist but are well drained and will tolerate acidic, neutral or alkaline pH. Hi Tornado can be placed on north-, south- or west-facing aspects and will tolerate both sheltered and exposed positions, but its H1a hardiness rating means it should be treated as tender — protect from severe winter cold. Use this cultivar at the front of mixed borders where its summer blooms can be seen at eye level, or grow it in a container for patios and terraces. In containers, move the pot to a frost-protected location or wrap the rootball in cold weather to reduce winter damage and help ensure June–September flowering in following seasons.
