About three years ago I purchased a cutting of Cereus comarapanus from a fellow gardener in San Diego area. Last night, the first flower showed up. This cactus produces red fleshed fruit, and I really looking forward to the fruit. However, the only other cactus pollen I had last night was from Lobivia silvestris flower. Let's hope C. comarapanus is self-fetrile, or can make fruit with L. sivestris pollen.
And the same flower this morning
