Maintenance

Drought Tolerant. Fern acacia will go dormant or die to the ground in Winter, but grows back quickly in Spring. In frost-free zones this plant can become a tall shrub. Trim dead foliage before Spring growth. Good as a ground cover and in prairie restoration. Plant on north or east slope, but can also take full sun on a south slope with some supplemental water. Propagation: Seed, Softwood cuttings,
