About Davidia involucrata

Davidia involucrata · also called Dove Tree, Handkerchief Tree · flowering

The dove tree is a striking deciduous tree famed for its spring display, when small flower heads are flanked by two large white bracts that flutter like handkerchiefs or doves. It prefers a sheltered spot in sun or part shade with moist, fertile, well-drained soil, and takes about a decade to begin flowering.

Cold limit: USDA 6-8 · RHS H5 (-20 to 30°C)

Watch for — Wind and late-frost damage: Exposed sites cause scorched foliage and damaged bracts; late spring frosts can brown the flower display. Plant in a sheltered position.

What davidia involucrata's hardiness rating actually means

Minimum temperature — and what happens below it

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

Concretely, for davidia involucrata 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 davidia involucrata go outside or overwinter — and where?

Plant it out within USDA 6-8 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 davidia involucrata can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H5 figure above.
