This compact hydrangea cultivar stands out with its impressive floral display and sturdy growth habit. 'Sublime Annabelle' produces large, cloud-like mophead flowers that emerge in a striking deep lime green hue, gradually transitioning to a soft white-green as they mature. Despite its dwarf stature, the plant boasts exceptionally strong branches that effortlessly support the abundant, oversized blooms, creating the illusion of floral clouds hovering above the foliage. One of its most remarkable features is its long flowering interest throughout the growing season with the spent blooms still providing colour well into autumn. The combination of its compact size, robust structure, and prolific blooming make this hydrangea an excellent choice for small gardens, mixed borders, or as a low-maintenance focal point in garden designs.
How to care for Hydrangea arborescens Sublime Annabelle ('SMNHRL') (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 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.
