Hydrangea paniculata ‚LC NO27‘ GROUNDBREAKER® RUBY panicle hydrangea

GROUNDBREAKER® is the world’s first series of groundcover panicle hydrangeas. The variety GROUNDBREAKER® RUBY produces flower clusters 15–20 cm tall, which open in July in creamy white and soon turn to a cherry‑red shade, while new blossoms continue to appear on the shrub in pure white. This creates a fresh, multi‑coloured effect throughout the summer. The plants reach only about 30–40 cm in height and about twice as much in spread, forming a very dense habit that perfectly covers the ground beneath them. For this reason, they are used as groundcover shrubs, as low and compact specimens in small gardens, or as edging along paths and borders of flower beds. They bloom from early July and stay beautiful until mid‑autumn, when the flowers gradually begin to dry. There is no need to cut them back immediately – they look very attractive even through winter, especially when touched by hoar frost. The deciduous leaves are oval to ovate, medium green, and healthy. The shrub becomes rich and offers sturdy branches and large flowers if it is pruned radically every spring before budding (March), leaving about 10 cm of previous year’s branches. It flowers on new wood.

Panicle hydrangeas grow best in full sun, though they can tolerate light partial shade. They are not particularly fussy about soil type but thrive in rich, well-drained conditions. Once established, they cope well with brief summer droughts, though consistent moisture helps keep them healthier. They respond well to fertilization, producing larger blooms and bushier plants. They adapt to any exposure and soil pH. Hardy down to –34 °C (USDA zone 4) and suitable for outdoor planters where they’ll simply need more frequent watering.
