About Pagoda Fawn Lily

Erythronium 'Pagoda' · also called Pagoda Fawn Lily, Pagoda Dogtooth Violet · flowering

Erythronium 'Pagoda' is one of the finest spring-flowering bulbs for the garden, a vigorous hybrid producing multiple sulphur-yellow, nodding flowers with reflexed petals and attractively mottled foliage in mid spring. An AGM-winning cultivar developed from Erythronium tuolumnense, it naturalises far more vigorously than most species and is ideal for bold woodland drifts or shaded borders. Long-lived and rewarding.

Minimum temperature — and what happens below it

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 pagoda fawn lily go outside or overwinter — and where?

Plant it out within USDA 4–9 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.
