Description
Hibiscus syriacus ‘Pink Chiffon’ is late-summer magic in shrub form—just when so many borders begin to soften, it steps in with a long, generous run of soft pink, semi-double flowers that look like they’ve been made from layers of tissue-thin silk.
Each bloom has that signature “chiffon” look: delicate, ruffled petals with a deeper pink eye, opening day after day from mid-summer into early autumn. It’s a brilliant shrub for bringing colour to the garden when you need it most, and it has a calm, elegant presence that works beautifully in both modern and cottage-style planting.
‘Pink Chiffon’ is hardy, easy to grow, and surprisingly unfussy once established. Give it sun, a reasonably free-draining soil, and a little patience in spring (hibiscus can be slow to leaf up), and it will reward you with years of reliable late-season flowering.
Caragh Garden Notebook
Planting:
Plant in spring or autumn. Choose a warm, sunny, sheltered spot for best flowering—against a wall or fence is ideal in cooler or exposed gardens. Dig a generous hole and improve the soil with compost. Plant at the same depth as in the pot, firm in gently, water well, and mulch to conserve moisture.

Soil Preparation:
Prefers moist, well-drained soil, but it’s adaptable once established. Improve heavy clay with compost (and a little grit if needed) to prevent winter wet. In very light soils, add organic matter to hold moisture.

Watering:
Water regularly in the first year, especially during dry spells. Once established, it’s fairly drought-tolerant, but it will flower more generously if it doesn’t dry out completely in summer.

Pruning:
Flowers are produced on new growth, so prune in late winter/early spring.

- Remove dead or weak stems.
- Shorten last year’s growth to 2–3 buds to encourage strong flowering shoots.
Don’t worry if it’s slow to start in spring—hibiscus often wakes up later than other shrubs.
Pests & Problems:
Generally trouble-free. Aphids can appear on soft new growth; usually managed with a gentle hose-down or by encouraging garden predators. In very exposed spots, buds can drop if the plant is stressed—sun, shelter, and steady moisture help.

Design Notes:
Perfect for late-summer colour in mixed borders, as a flowering screen, or as a specimen shrub. Looks beautiful with ornamental grasses, lavender, perovskia, salvias, echinacea, and other sun-lovers. Great for pollinators too.
