About Bisset's Bamboo

Phyllostachys bissetii · also called Bisset's Bamboo, David Bisset Bamboo · tropical

Bisset's Bamboo is a cold-hardy, medium-sized running bamboo widely used for screens and hedges in temperate climates. It produces dense, dark-green foliage on upright olive-green culms and tolerates wind, pollution, and brief periods of drought. One of the most reliable screening bamboos for UK and northern US gardens.

Cold limit: USDA 5-9 · RHS H6 (-20 to 35°C)

What bisset's bamboo's hardiness rating actually means

Yes — bisset's bamboo is genuinely cold hardy. Rated RHS H6 and USDA 5-9, it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H6 means: Hardy throughout the UK and northern Europe. On the US scale that maps to USDA 5-9 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −20 to −15 °C. Bisset's Bamboo is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for bisset's bamboo as it gets too cold:

It tolerates winter lows to about −20 to −15 °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 bisset's bamboo go outside or overwinter — and where?

Plant it out within USDA 5-9 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 bisset's bamboo can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H6 figure above.
