Minimum temperature — and what happens below it

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

It tolerates winter lows to about −20 to −15 °C once established.

First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can tulipa 'flaming parrot' go outside or overwinter — and where?

Plant it out within USDA 3-8 (winter-chill bulb; pre-chill or lift in zones 9-10) 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 tulipa 'flaming parrot' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H6 figure above.
