Hibiscus syriacus is a species of flowering plant in the mallow family Malvaceae, native to India and Asia. It was given the epithet syriacus because it had been collected from gardens in Syria.
Common name : Rose Of Sharon
Scientific name : Hibiscus syriacus
Family : Malvaceae
Category : Shrubs
Type of plant : Perennial
Hibiscus syriacus is a hardy deciduous shrub, upright and vase-shaped, reaching 2–4 m (7–13 ft) in height, bearing large trumpet-shaped flowers with prominent yellow-tipped white stamens. The flowers are often pink in color, but can also be dark or light pink, or even white. It thrives on a moist but well-drained mixture of sand, clay, chalk, and loam but is highly tolerant of air pollution, heat, humidity, poor soil and drought. The species has naturalized very well in many suburban areas, and might even be termed slightly invasive, so frequently it does seed around.

Identify my rose of sharon
Rose of Sharon is an upright deciduous shrub with leaves 8 cm long, with three slightly toothed lobes.
The flowers appear in the axils of the leaves, measure 5 cm on average, and have a funnel shape with 5 petals.
Plant my rose of sharon
In open ground, plant preferably in autumn, or possibly in early spring, outside freezing periods.
Find a sunny spot in humus soil, cool and drained, neutral or alkaline. Plan that your rose of Sharon will measure 3x2m, so keep a meter between each plant unless you want to prune it a lot later.
When planting, make a hole 1/3 wider than the root ball, possibly soak it, plant without burying the root collar, that is the limit between roots and branches. Water copiously.
In pots, plant in a mixture of garden soil and mature compost, in a large pot - 20L minimum - provided with a cup. Water and mulch.
Water my rose of sharon
Water regularly and generously for several weeks after planting or sowing, especially if you did it late in the season. After, you only have to worry about watering if your plant is potted. Outside of these conditions, it will manage on its own.
Repot my rose of sharon
If you keep your rose of Sharon in pots, plan for a replacment of the topsoil every 2 to 3 years.
Prune my rose of sharon
The althea blossoms on the wood of the year, so you can prune it in early spring but just remove entangled stems, and "aerate" the heart of the shrub.
Mulch my rose of sharon
Renew the mulching in the fall at the foot of your rose of Sharon.
