Garden & Ecology Notes

Minimum Light:

Part Sun

Best Light:

Full Sun

Habitat:

Rocky outcrop, Montane, Grassland, Alpine

Wildlife Value:

bees, butterflies

Deer Resistant:

Yes

Ecology:

An alpine calciphile characteristic of limestone screes, cliffs, and rocky pastures in European mountain ranges. The dense, shaggy white hairs on foliage and stems reduce moisture loss and reflect intense ultraviolet radiation in high-altitude environments.

Soil Requirements

Soil:

limestone

pH:

alkaline

Drainage:

well-drained

Moisture:

dry to moderate

Notes:

Obligate calcicole found on rocky, shallow substrates derived from limestone and dolomite, including scree, gravelly debris, and rock crevices.

Propagation & Germination

Notes:

Seeds germinate readily at 18-22°C within 2 to 4 weeks; light may aid germination, so surface sow or cover very lightly.
