Hydrangea paniculata Diamant Rouge ('Rendia') (PBR)
hydrangea
When they first appear, the petal-like sepals of Hydrangea paniculata Diamant Rouge are white, but they soon start to change colour, first to pink and then a deeper shade of rich raspberry red. These flowerheads appear in profusion on strong stems and can grow up to 35cm (14in) in length. The flower colour may vary slightly depending on the exposure and soil type, but the overall effect is quite dramatic when the plant is in full bloom.
How to care for Hydrangea paniculata Diamant Rouge ('Rendia') (PBR):
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.
Once established, to enhance flowering prune hard in late winter/early spring cutting back the previous season's shoots to within a few buds of the permanent, woody framework of the plant.
