Origin and Habitat: Arizona, Mexico.
Is a solitary barrel cactus
Flowers: Reddish outside, brilliant red inside
F. emoryi produce nectar in the nectaries at the top of the cactus that feed the ants that live around its base. In turn, the ants are very territorial and seem to protect the plants from other insects that might try to walk up the stem and damage the fresh, delicate cells at the growing apex or steal nectar or pollen from the flowers. This strategy is useful to not only to protect the plant from small herbivores but also to promote outcrossing pollination because the only bugs that can successfully visit the flowers without being attacked by the ants are flying pollinator insects like butterflies and bees that carry pollen from other individuals and other populations, in turn increasing the genetic diversity of the species.
It grows up to about 150cm high and 50cm thick. It has about 21 ribs and the central spines are more erect and very long.
Cultivation and Propagation: Slow growing to start but does well under cultivation. Use very draining soil, water during the aestival growth cycle (this plant need plenty of water) But needs to be avoided wetting the bodies of these plants while they are in sunlight.A wet cactus in the sun light can cause sun burning which can lead to scars or even fungal infections or even fungal infections and death.
Needs full sun. Keep dry at 10°C in winter, but can tolerate sporadic light frost.
