A drought-tolerant southwestern shrub with delicate pink or white flowers that typically open in late afternoon. Best suited for arid and semi-arid gardens with minimal water requirements.

Why grow it

Wishbone bush offers reliable performance in low-water landscapes where many ornamental shrubs struggle, making it a practical choice for water-conscious gardeners in arid regions. Unlike some drought-tolerant alternatives, it provides consistent afternoon flowering over an extended season, adding visual interest during peak heat when many plants are dormant. Its modest size and open growth habit make it useful for understory positions or accent plantings without requiring significant pruning or maintenance.

Watch out for

In areas with regular summer irrigation or high humidity, the plant may become leggy or prone to fungal issues, so site selection and soil drainage matter more than in its native range. Young plants benefit from consistent moisture during establishment, despite their ultimate drought tolerance. The plant's self-seeding tendency can become prolific in ideal conditions, requiring occasional management if spread is not desired.
