Trumpet Flower Cactus
Full Sun; Filtered Sun
The Tricholobivia hyb., commonly known as Trumpet Flower Cactus is a cross between two families. It is a compact cactus growing 1 foot tall and 6 inches wide in either rounded or columnar form. The ribs run vertically along the green stem and it's covered in short spines. The hybridization combines huge flowers with brilliant colors of red, yellow, pink, orange or white and the normally night-blooming cactus now becomes a day-bloomer, spring through fall. It is a hardy cactus able to withstand temperatures into the single digits. Prefers full sun with fertile well draining soil.
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.
