Androsace carnea
Androsace carnea

General Information:

This species is native to the western Alps and eastern Pyrenees, growing in alpine habitats at elevations up to 1900 m. It generally grows on granitic rock. Plants form evergreen rosettes of small, narrow leaves. The flowers are produced in umbels on stems 5-15 cm tall. Flowers, 5-9 mm in diameter, are pink or white, with yellow eyes. There are several subspecies available including rosea (halleri), laggeri (deep pink) and brigitanica (white). In the wild, it generally blooms in June.

Cultivation:

This is perhaps the easiest Androsace to grow so is recommended for beginners. It may be short-lived so saving seed is suggested. Unlike many Androsace, this species prefers acidic soil rather than alkaline. Full sun and well-drained soil are essential. It is an ideal species for growing in crevice gardens or alpine troughs. Zone 5-8.

Bloom Period:

As early as April in mild areas or as late as June in cooler areas.

Seed:

Seeds need light for germination. They also require 6-8 weeks of stratification. Some growers provide them with 6 weeks of 20 C first, followed by the stratification period. Once stratification is complete, germinate them cool, 10-15 C. This will keep them more compact.
