About Souvenir de la Malmaison Rose

Rosa 'Souvenir de la Malmaison' · also called Souvenir de la Malmaison, Queen of Beauty and Fragrance · flowering

Souvenir de la Malmaison is a classic Bourbon rose from 1843, prized for large, flat, quartered blush-pink blooms packed with petals and a rich, spicy old-rose fragrance. Repeat-flowering and available as bush or climbing forms, it performs best in warm, dry climates because its full flowers ball and spoil in persistent rain. Often nicknamed the Queen of Beauty and Fragrance.

Mature size: Bush form about 1.2-1.5 m (4-5 ft) tall and wide; the climbing sport reaches 2.5-3.5 m (8-12 ft).

Watch for — Balling in rain: The densely petalled blooms trap rain, fail to open and rot brown; site in a warm, dry, sheltered spot and remove spoiled flowers promptly.

Indoor size vs how big it gets in the wild

Souvenir de la Malmaison Rose is a garden shrub whose final size is set more by your secateurs than by the plant — pruning, not luck, decides how big it gets. Indoors and in a pot, expect bush form about 1.2-1.5 m (4-5 ft) tall and wide. In the ground with no restriction it is a completely different plant — the climbing sport reaches 2.5-3.5 m (8-12 ft). — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Left unpruned it builds a woody framework that gets taller and wider every year; with annual pruning you hold it at whatever size suits the space.

Growth rate and years to mature

Its feeding profile backs this up: feed with a balanced rose fertiliser in early spring and again after the first flush, with an annual mulch of rotted manure. it resents hard pruning, so feed to sustain growth rather than cutting back severely.

How to keep souvenir de la malmaison rose smaller

You are not stuck with the maximum size. For souvenir de la malmaison rose specifically, these are the levers, in order of impact:

Prune souvenir de la malmaison rose annually at the right time for its type — this is the primary, expected way to control its size.
Remove the oldest, thickest stems at the base each year to keep it open and within bounds.
Growing it in a large container rather than open ground naturally restricts the ultimate size.
Avoid heavy feeding if you want to limit growth — rich soil and lots of nitrogen drive bigger, faster shrubs.

The keep-it-smaller method, step by step

Prune at the right time. Time the cut to souvenir de la malmaison rose's type (after flowering for many spring shrubs, late winter for summer-flowering ones) so you do not lose the next display.
Take out the oldest stems. Remove up to a third of the oldest, thickest stems at the base to renew the shrub and contain it.
Shorten the rest. Cut the remaining stems back to an outward-facing bud at the height and width you want.
Restrict the roots. For a permanent size cap, grow it in a large container rather than open ground.
