Rosa ‘Royal Occasion’ is a classic floribunda that creates a clear red mass rather than one formal show bloom. Upright shoots carry clusters of five to ten bright-red, semi-double cup-shaped flowers above dense dark foliage. Its vigorous compact structure repeats the display and quickly fills a sunny border with steady colour, without demanding the volume of a large shrub rose.
Plant it in a group of three for one red wave, or as an upright central mass behind lower soft foliage, with enough room for air around each shrub.
New Zealand Rose Trials Certificate of Merit 1976 · former 1974 ADR, later withdrawn.
Three elements define this exact cultivar’s form and presence.
Inflorescences gather several semi-double corollas at the top of each strong shoot.
Fewer than about twenty-five petals leave part of the stamens visible as the bloom opens.
Several basal canes create a compact vertical mass suited to group planting.
Why you will love it: because bright-red clusters flower on a sturdy upright floribunda crown, delivering clear colour without a heavy dark effect.
Allow 50–75 cm of width in full sun, with fertile free-draining soil and clear air movement between shrubs.
Keep the flower colour clear with blue, silver or yellow accents from plants sharing full sun, airflow and free-draining soil.
Full sun, ideally at least six hours, with air moving around the foliage.
Water deeply when the upper 3–4 cm have dried; avoid small daily amounts.
A hardy deciduous plant; protect the pot from prolonged hard frost and drying wind.
Not intended for eating. Wear gloves around prickly canes and keep treated plant parts away from children and animals.
Full sun, ideally at least six hours, with air moving around the foliage.
Water deeply when the upper 3–4 cm have dried; avoid small daily amounts.
Deep fertile but free-draining soil with organic matter and no standing water around roots.
Balanced feed at growth onset and a second light application after the first flush, always on moist soil.
Prune in late winter according to the natural habit, removing dead, weak or crossing canes. Prune in late winter at staggered heights above outward buds and remove one old or weak cane from the base.
Water at the root, clear fallen leaves and inspect young shoots for aphids or fungal spotting.
After planting it develops a few strong upright basal canes and its first flower clusters on young tips.
Each annual renewal adds flowering laterals, distributing clusters of five to ten blooms across more levels.
At maturity it reaches 70–95 cm high and 50–75 cm wide, forming a compact upright floribunda with repeated bright-red flushes.
The deciduous shrub settles at 70–95 cm high and 50–75 cm wide without losing its natural branching.
Both drawings show the same natural architecture as foliage, flowers and active growth change.
What to expect after planting: Retain three to five strong basal canes and remove weak inner growth so the upright crown stays airy without losing substance.
‘Royal Occasion’, also known as ‘Montana’, was bred in Germany by Mathias Tantau Jr. The cross ‘Walzertraum’ × ‘Europeana’ produced the selection introduced in 1974 as a vigorous red floribunda.
The cultivar was recorded and distributed internationally under both names. It received ADR recognition in 1974, but that historic certification was later withdrawn; in 1976 it gained a Certificate of Merit at the New Zealand Rose Trials. The old ADR is retained only as a historical fact, not as a current award mark.
Lateral flowering axes end in corymb-like clusters, allowing several flowers to open close together and form one mass of colour.
If a fertilised flower is retained, the fleshy outer hip develops mainly from the floral receptacle enclosing many small achenes.
Six practical answers covering position, water, seasonality, pruning, mature scale and safety.
Full sun, ideally at least six hours, with air moving around the foliage.
Water deeply when the upper 3–4 cm have dried; avoid small daily amounts.
Yes; it needs a deep 40–50 cm pot, full sun and steady feeding so the upright canes can support successive flower clusters.
Prune in late winter according to the natural habit, removing dead, weak or crossing canes.
At maturity it reaches about 70–95 cm high and 50–75 cm wide, with a natural upright compact dense deciduous floribunda shrub.
