El Niño Desert Orchid Thrives Despite Heat and Drought

El Niño desert orchid is a unique hybrid shrub that brings fragrant pink flowers to the garden even in times of drought and hot weather.

El Niño desert orchid (Chitalpa 'NCXC1') is a unique shrub that grows quickly and blooms in summer, with fragrant pink flowers. Highly heat- and drought-tolerant, it performed exceedingly well in plant trials at Louisiana State University. While drought killed most of the trial plants in 2023, El Nino was noted to be “living in an alternate universe,” putting on several feet of growth after spring planting, blooming well and remaining attractive through the summer. This intergeneric hybrid also resists deer.

El Niño desert orchid, a large shrub, combines genetics of desert willow and catalpa. Its leaves resemble those of the former while its flowers are reminiscent of catalpa, only pink.
