Perfect for moonlit gardens. From spring through late summer it produces masses of huge white flowers that open in the late afternoon. They close in the morning as temperatures heat up, fading to pink. The fragrant flowers are at least 4 inches in diameter, and stand out against the large dark green leaves. Excellent addition to your wildlife habitat attracting the nighttime pollinators. Needs excellent drainage.

Growing Plants in the Desert — Important Information

The information presented here is, to the best of my knowledge, accurate and based on my research from reliable sources, observations I have made of plants growing in my, and other gardens I have visited, and observations of the plants in their native habitats. I would appreciate your feedback and experience to help me educate others! 


Cacti: In my experience, cacti are much happier in the filtered shade here in the low desert of the Coachella Valley. Colors are more vibrant and they bloom more profusely, especially the non-native varieties. If you pay attention to how our native barrel and beavertail opuntia grow in the wild, it is frequently tucked in the rocks under creosote or another shrub.


Light Requirements: I have found that in our desert (Sonoran/Colorado) “full sun” plants can take and appreciate the late afternoon filtered sun, especially in the hot summer months.
