Hydrangea arborescens Lime Rickey ('Smnhalr') (PBR)
- Position: full sun or partial shade
- Soil: moist, well-drained, moderately fertile, humus-rich soil
- Rate of growth: average
- Flowering period: July to September
- Hardiness: fully hardy
The large domed flowerheads emerge a fresh lime green in midsummer but gradually fade to white as the season progresses. Their cool colouring provides a good contrast to richer purples and plums, but they will also add a bit of depth to more monochrome schemes. An easy to grow deciduous shrub that offers a lot of bang for the buck, and the flowers last for ages and are great for cutting and can be used in both fresh or dried arrangements.
- Garden care: Hydrangeas do not like to dry out. In dry weather, soak the roots with a hose and the plant will usually recover. 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. Mulch young plants with a well-rotted manure or compost in spring. Once established, remove a quarter to a third of the shoots to the base of the plant.
