Aquilegia chaplinei - my own attribution

Rare. Well I think it is. It breeds true and is a short stature columbine perfect for rock gardens. Hardy and evergreen, looking more like a tiny thalictrum with ferny foliage. The leaves are glaucous and so very pretty with darker stems that are almost red. Lemon flowers in summer.  Extremely hardy and tough.  See wikipedia's info which is fascinating. 20-40cm

Native to the arid Guadalupe and Sacramento Mountains of West Texas and southeastern New Mexico in the West South Central United States. A. chaplinei is characterized as a dwarf version of its close relative Aquilegia chrysantha and is sometimes considered a variant of this species under the name Aquilegia chrysantha var. chaplinei.

The plant has been the subject of conservation protections, including a New Mexican law prohibiting the collection of seeds from wild examples. In 2017, as it was under threat due to human threats of dams and disturbance.

Most interesting is that the plant is monoecious through its unisexual flowers often a sign that the plant is rare and isolated and is an evolutionary advantage allowing them to reproduce successfully even without a second plant of the same species.
