Purpleleaf Sand Cherry Unsuitable for Central California

Zone Mismatch

Prunus × cistena is rated Zones 3–7. Central CA (Zone 9, 100°F+ summers) exceeds its heat tolerance. It may survive a few years but will likely suffer dieback, borers, and premature death.

Better Alternatives for Zone 9

Prunus cerasifera 'Krauter Vesuvius' (purple leaf, heat tolerant)
Lagerstroemia (crape myrtle) cultivars with burgundy foliage
Cercis canadensis 'Forest Pansy' (redbud, Zone 9 adaptable)
