About Pecan 'Elliot'

Carya illinoinensis 'Elliot' · also called Elliot pecan, scab-resistant pecan · edible

'Elliot' is a smaller-nutted Southeastern pecan prized above all for excellent pecan-scab resistance, making it a backbone cultivar in the humid Deep South. The kernels are small but richly flavoured with high oil content. A Type II (protogynous) cultivar, it pollinates well with protandrous types like 'Pawnee' or 'Desirable'.

Cold limit: USDA 6-9 (well suited to the humid Southeast) · RHS H5 (-15 to 38°C)

What pecan 'elliot''s hardiness rating actually means

Yes — pecan 'elliot' is genuinely cold hardy. Rated RHS H5 and USDA 6-9 (well suited to the humid Southeast), 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 6-9 (well suited to the humid Southeast) — 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. Pecan 'Elliot' is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for pecan 'elliot' 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 pecan 'elliot' go outside or overwinter — and where?

Plant it out within USDA 6-9 (well suited to the humid Southeast) 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 pecan 'elliot' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H5 figure above.
