About Ogeechee Tupelo

Nyssa ogeche · also called Ogeechee Tupelo, Ogeechee Lime · edible

A small to medium deciduous tree native to the swamps of Georgia and northern Florida, famed as the source of the prized Tupelo honey — one of the rarest, most expensive honeys in the world. Its large, cream-white flowers are immensely attractive to bees in spring, and the tart red drupes (ogeechee limes) were historically used as a citrus substitute for flavoring. Highly flood-tolerant.

Cold limit: USDA 6-9 · RHS H4 (-12 to 40°C)

Watch for — Extremely limited range / cold hardiness: Nyssa ogeche is naturally confined to a small area of Georgia and Florida and is marginal in hardiness outside USDA zones 7–9. In zone 6 it may suffer winter dieback; plant in a sheltered, south-facing position or provide winter protection.

What ogeechee tupelo's hardiness rating actually means

Yes — ogeechee tupelo is genuinely cold hardy. Rated RHS H4 and USDA 6-9, it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H4 means: Hardy in an average winter across much of the temperate world. On the US scale that maps to USDA 6-9 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −10 to −5 °C. Ogeechee Tupelo is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for ogeechee tupelo as it gets too cold:

It tolerates winter lows to about −10 to −5 °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 ogeechee tupelo go outside or overwinter — and where?

Plant it out within USDA 6-9 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 ogeechee tupelo can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H4 figure above.
