What are the horticulural aspects of Ursinia anthemoides?

Ursinia anthemoides grow in a variety of conditions, from full sun to partial shade, and can tolerate a range of soils, including clay, loam, and sand. It is drought-tolerant but performs best with regular watering. Annuals thrive in temperatures between 15-25°C.

Plant silver daisy seeds in fall or early spring, about 2-3 mm deep, in well-draining soil. Transplant seedlings 30-40 cm apart after 8-10 weeks. Deadhead regularly to encourage more blooms. Prune the plant back after flowering to maintain shape and promote new growth.

Harvest silver daisy flowers in the morning, when petals are fully open. Cut the stems at an angle, and remove any lower leaves to prevent water from collecting in the leaf axils. Hang the stems upside down to dry, or use a desiccant to preserve the flowers for arrangements.
