About Jasminum beesianum

Jasminum beesianum · also called red jasmine, Bees' jasmine · flowering

Bees' jasmine is an unusual semi-evergreen to deciduous twining climber from western China bearing small, fragrant, deep rose-pink to red flowers in early summer, followed by shiny black berries. Hardier than many jasmines, it suits a sunny or part-shaded wall in well-drained fertile soil. True Jasminum species are listed by the ASPCA as non-toxic to cats and dogs.

Cold limit: USDA 7-9 (outdoor garden climber in mild temperate areas) · RHS H5 (hardy in most places throughout the UK even in severe winters) (-10 to 25°C)

What jasminum beesianum's hardiness rating actually means

Yes — jasminum beesianum is genuinely cold hardy. Rated RHS H5 and USDA 7-9 (outdoor garden climber in mild temperate areas), it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H5 means: Hardy in most of the UK and in cold winters. On the US scale that maps to USDA 7-9 (outdoor garden climber in mild temperate areas) — the zones where it can be left outdoors year-round.

New to these scales? The USDA hardiness zone map explained covers how the zone numbers work, and you can find your own zone with the zone finder.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −15 to −10 °C. Jasminum beesianum is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for jasminum beesianum as it gets too cold:

It tolerates winter lows to about −15 to −10 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can jasminum beesianum go outside or overwinter — and where?

Plant it out within USDA 7-9 (outdoor garden climber in mild temperate areas) and it overwinters with little or no help.
It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when jasminum beesianum can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H5 figure above.

Frost protection for borderline jasminum beesianum

Jasminum beesianum is right on a hardiness edge in many gardens, so if you are pushing it, these measures buy it the margin it needs:

At the cold edge of its range, mulch the root zone in late autumn to buffer the deepest freezes.
Protect container specimens — pots freeze through far faster than open ground, costing roughly a zone of hardiness.
Shelter new growth from late spring frosts with fleece if a hard night is forecast.

Jasminum beesianum hardiness — frequently asked questions

Is jasminum beesianum cold hardy?

Yes — jasminum beesianum is genuinely cold hardy. Rated RHS H5 and USDA 7-9 (outdoor garden climber in mild temperate areas), it lives outdoors all year and needs winter cold rather than protection from it. An outdoor plant. Jasminum beesianum is hardy across USDA 7-9 (outdoor garden climber in mild temperate areas); it belongs in the ground or a frost-proof container, not on a windowsill, and many types actively need a cold winter to perform.

What is the minimum temperature jasminum beesianum can survive?

Minimum survivable temperature is roughly about −15 to −10 °C. Jasminum beesianum is built for winter — once established it takes hard frost and snow in its stride.

What hardiness zone is jasminum beesianum?

Jasminum beesianum is rated USDA 7-9 (outdoor garden climber in mild temperate areas) and RHS H5 — Hardy in most of the UK and in cold winters.

Can jasminum beesianum survive winter outside?

Plant it out within USDA 7-9 (outdoor garden climber in mild temperate areas) and it overwinters with little or no help. It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy. The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.

How do I protect jasminum beesianum from frost?

At the cold edge of its range, mulch the root zone in late autumn to buffer the deepest freezes. Protect container specimens — pots freeze through far faster than open ground, costing roughly a zone of hardiness. Shelter new growth from late spring frosts with fleece if a hard night is forecast.
