About Spanish Lavender

Lavandula stoechas · also called Butterfly Lavender, Topped Lavender · herb

Spanish lavender is a compact Mediterranean subshrub prized for its pineapple-shaped flower heads topped with showy rabbit-ear bracts.

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 spanish lavender go outside or overwinter — and where?

Plant it out within USDA 8-9 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.
