About Compassion Rose

Rosa 'Compassion' · also called Compassion, Harquest · flowering

Compassion is an outstanding repeat-flowering climber bred by Harkness in 1972 and holder of the RHS Award of Garden Merit. Its fully double, salmon-pink blooms flushed with apricot reach about 10 cm across and carry a strong, sweet fragrance. Upright and vigorous with glossy dark foliage and good disease resistance, it suits walls, arches and pillars.

Mature size: About 3 m (10 ft) tall and 1.8-2.4 m (6-8 ft) wide when trained on a support.

Watch for — Bare base: Climbers trained too vertically flower only at the top; bend and tie canes horizontally to break apical dominance and bloom lower down.

Indoor size vs how big it gets in the wild

Compassion 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 about 3 m (10 ft) tall and 1.8-2.4 m (6-8 ft) wide when trained on a support.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

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

Compassion Rose is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: feed with a balanced rose fertiliser in early spring and again after the first flush, mulching annually with compost or rotted manure. stop feeding in late summer so new wood hardens before winter.

Want this turned into the right next pot at the right moment? The pot size calculator and the compassion rose repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast compassion rose grows.

How to keep compassion rose smaller

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

Prune compassion 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 compassion 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.

How to grow compassion rose bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for compassion rose the accelerators are:

Plant it in open ground in good soil — far more vigorous than a container-restricted plant.
Full sun (which it wants) plus an annual mulch and feed gives the strongest growth.
Water well through the first establishment years; a settled root system drives the fastest size gain.

Light is almost always the ceiling. The compassion rose light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When compassion rose outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for compassion rose:

It shades or crowds neighbouring plants, or blocks a path it used to clear.
Bare, woody, unproductive centres with growth only on the outside — a sign it needs renovation pruning.
It has clearly exceeded the space you allotted and an annual trim no longer holds it.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the compassion rose repotting guide. If you want more of this plant instead of a bigger one, the compassion rose propagation guide turns prunings into new plants.

How big does compassion rose get?

Compassion Rose reaches about 3 m (10 ft) tall and 1.8-2.4 m (6-8 ft) wide when trained on a support. when grown indoors. 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.

Is compassion rose slow or fast growing?

Compassion Rose is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Compassion 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.

How long does compassion rose take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.
