Hibiscus syriacus ‘Rwoods5’ Magenta Chiffon® gives the second half of summer a colour that feels deep, velvety and almost electric. Broad magenta petals surround a rich centre of petaloid staminodes, like a small rosette folded inside the corolla. Against the upright dark-green crown, every flower gains a clear outline and supplies intensity just as spring-flowering shrubs have quietened.
As a vertical accent in a sunny border, flowering hedge or large container, it supplies height without dense evergreen weight. Late bloom links summer with autumn and creates a second peak among ornamental grasses and long-season perennials.
Plantarium Silver Medal 2016 — verified for MAGENTA CHIFFON® ‘Rwoods5’.
Three distinct details explain the horticultural value of Magenta Chiffon®.
Petaloid stamens fill the centre without hiding the flower’s elegant funnel.
New growth continues setting buds after many spring shrubs have finished.
Its vase-shaped crown supplies vertical structure while leaving room for lower planting at the base.
Why you will love it: Deep magenta and an almost double chiffon centre give late-season flowering unusual saturation and texture.
Use at the rear of a sunny border or as a bold late-season note in a flowering hedge, with air around the upright crown and enough width for the deep magenta flowers to remain distinct from neighbouring shrubs.
Salvia yangii, Pennisetum alopecuroides and Echinacea ‘White Swan’ enjoy sun and drainage; silver haze, moving seedheads and white discs allow the double magenta flowers to dominate.
Full sun for dense growth and plentiful buds; morning sun is useful in extreme heat.
Provide moderate but deep water once established. Avoid both chronic drought and heavy saturated soil.
Hardy to roughly −20 °C or below depending on site and clone; late spring emergence is entirely normal.
An ornamental cultivar, not intended for consumption.
Full sun for dense growth and plentiful buds; morning sun is useful in extreme heat.
Provide moderate but deep water once established. Avoid both chronic drought and heavy saturated soil.
Fertile, well-drained soil from slightly acid to alkaline. A warm sheltered site ripens the wood more effectively.
Apply compost and a balanced feed as new growth starts; avoid excess nitrogen that produces length rather than flowers.
It flowers on new growth. In late winter thin weak stems and shorten the framework to improve branching.
It loses its leaves and remains woody. Do not assume the bare plant is dead before its characteristically late spring growth.
The first season builds roots and a woody base even when spring emergence appears slow. Current-season shoots will carry the late flowers, so there is no reason to remove them prematurely.
The upright woody crown rises and branches before filling in late summer with almost double magenta corollas.
At full maturity the crown reaches about 2.4–3.7 m in height and 1.8–3 m in spread. Final planting distance must follow that scale rather than the plant’s current young volume.
Side elevation: An indicative natural silhouette using published mature dimensions, not the plant’s current delivery size.
The seasonal cycle of Hibiscus syriacus ‘Rwoods5’ MAGENTA CHIFFON® is a deciduous hardy woody shrub; its bare winter form is natural.
Within Dr Roderick Ian Woods’ Norfolk programme, seed for ‘Rwoods5’ came from a planned 2006 cross using proprietary selection 7060 as the seed parent and 5954 as the pollen parent. The objective was a fuller flower with a clear, intense magenta colour.
An interesting seedling was identified in September 2008 and final selection followed in 2011. Grafting and softwood cuttings confirmed that the fully double RHS Red-Purple 71B flower, vigorous growth and good branching repeated true to type. The cultivar was later protected under USPP29683.
Proven Winners introduced it into the Chiffon Series as MAGENTA CHIFFON®. A Plantarium silver medal in 2016 recognised a genuine expansion of the series: not another pastel variation, but a deep magenta, almost fully double expression of its characteristic chiffon structure.
In ‘Rwoods5’, the identity shift within the male floral whorl is extensive: many stamens develop as broad petaloid staminodes that fill the centre. Magenta Chiffon® therefore approaches a double rather than the usual semi-double form.
Cyanidin-type anthocyanins absorb green wavelengths and return red-violet light to the eye. Concentration, vacuolar pH and co-pigments shift the result toward the deep magenta seen in ‘Rwoods5’.
Six exact answers about placement, watering, pruning and seasonal behaviour for Magenta Chiffon®.
It can grow in a very large pot, but a mature scale of 2.4–3.7 m × 1.8–3 m makes open ground the better long-term choice. In a pot, monitor moisture and root space more frequently.
Full sun for dense growth and plentiful buds; morning sun is useful in extreme heat. Keep an open visual field around its mature 1.8–3 m spread so the cultivar’s particular crown remains clearly legible.
Provide moderate but deep water once established. Avoid both chronic drought and heavy saturated soil.
Magenta Chiffon® flowers on current-season shoots. Wait for buds to swell in late winter or early spring, then remove dead, weak or crossing wood.
‘Rwoods5’ is described as nearly to fully double because many stamens have developmentally transformed into petaloid organs filling the centre.
Magenta Chiffon® is deciduous and remains outdoors. A bare crown is normal and spring emergence is late; assess stem life when buds begin to swell.
