Gardeners seeking long-lasting summer color without the fuss of peonies are being urged to consider hardy hibiscus as a low-maintenance alternative. According to Ideal Home, the hardy hibiscus, most commonly Hibiscus syriacus, extends color well beyond the peak of summer, flowering from late summer into early autumn.
Why Hibiscus Outperforms Peonies
Dr Russell Sharp, founder of Eutrema, explained that peonies are a "shorter season plant" that provide "a strong but relatively brief display in the late spring to early summer." In contrast, hardy hibiscus keeps borders looking active when many earlier flowering plants fade. "That difference in timing is often the deciding factor if the aim is to maintain interest in the garden for longer rather than concentrating colour into a single moment," he said.
Low-Maintenance Blooms
Unlike peonies, which require precise planting depth and drainage to avoid underperforming for years, hibiscus can thrive even with imperfect care. However, some basic maintenance is still needed. Richard Barker, horticultural expert and commercial director from LBS Horticulture, advises feeding outdoor hibiscus annually in spring with a slow-release fertiliser high in potassium, such as rose feed.
Pruning and Winter Care
If hard frosts cause the plant to die back in autumn, cut the dead stems back to a few centimetres above ground level. Barker added: "Once your hibiscus has reached around 1.5m in height, you should begin pruning annually to help the plant keep its shape. Prune after flowering, cutting back each branch to just above a leaf node and removing old wood from the middle of the plant to improve air circulation."
