Adonis pyrenaica is a clump forming perennial native to the Pyrenees of Spain and France, and a few isolated locations in the Maritime Alps. Plants grow in moist rocky pastures and on coarse settled scree at elevations between 1300-2500m. The leaves form on stems that usually range from 20-50cm high, although their height can vary depending on local conditions. Adonis pyrenaica is one of the standouts in its native region for its large bright yellow flowers and its ability to form colonies.
Cultivating Pyrenean pheasant's eye out of its native range is challenging but can be done successfully if the proper precautions are taken. The seeds have a very short period of viability, and therefore obtaining fresh seeds is very important (which can be a difficult task - check specialist alpine gardening nurseries). Plants should be grown in moist soil that won't dry out. It is recommended that a few large rocks be placed in the bed. The roots apparently grow deeply, so deep soil must also be provided.
