Description:
Rock-Daisy is a tough, wiry plant that clings to rocky terrain. It has small, daisy-like yellow flowers with narrow petals and toothed, green leaves. The plant grows in clumps or mats from crevices and cracks, often looking like it's growing straight out of bare rock. It's well adapted to dry, rugged conditions.
Uses:
Mainly valued for erosion control and native habitat support. It attracts native pollinators like bees and beetles. Not traditionally used for food or medicine, but plays a quiet, steady role in desert ecosystems.
Note:
Rock-Daisy lives up to its name—small, bright flowers growing from harsh places. It’s a desert survivor that adds a splash of yellow to rocky, unforgiving landscapes.
