Hibiscus 'Red Heart'

Rose of Sharon 'Red Heart' (Hibiscus syriacus 'Red Heart'). Hibiscus syriacus 'Red Heart' is a vigorous and highly contrasting ornamental shrub, renowned for its large, bright white flowers adorned with a distinct dark red heart. This classic variety offers abundant and long-lasting summer blooms, bringing brightness and structure to the garden. Its upright and robust habit makes it an excellent choice for tall flowering hedges, screens, or as a specimen plant. The deciduous dark green foliage perfectly highlights the blooms and supports regular and sustained growth.

To plant Rose of Sharon 'Red Heart', choose a suitable exposure: full sun. The recommended soil is: ordinary to rich, well-drained. Water the root ball before planting and ensure water can drain after planting. During establishment, check the soil moisture by hand before watering again. Spread mulch around the base, leaving the root collar clear. Avoid systematic fertilizer applications without considering soil richness. In Quebec, choose a period when the ground is thawed and easy to work.

Allow a width of 2–3 m (6–10 ft) to plan the placement of this plant in the garden. The indicated height of 3–4 m (10–13 ft) helps choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Pair this variety with plants that have compatible light and water needs. If you are considering a container, first check that its volume and drainage are suitable for root development. Potted roots are more exposed to cold than those planted in the ground.
