Description: X Ferobergia is a horticultural intergeneric hybrid, made by crossing of Ferocactus fordiiSN|12330]]SN|12330]] as a female and Leuchtenbergia principisSN|12924]]SN|12924]] as a male. F2 hybrid means the plant of second generation is derived from cross-pollination among F1 hybrids. These have unpredictable characteristics and produce offsprings unlike themselves. It produces drops of nectar from areolar glands like Ferocactus.
Blooming season: May-September

Cultivation and Propagation: Ferobergias grow easily from seed in cultivation. Despite being revered by many collectors, they are not too difficult to cultivate.
Soil: Use a very quick-draining mineral mix.
Water: Water just enough, if possible from below. Water carefully. Lack of water will make the tip of the tubercles yellow. Too much water will make it rot.
Repotting: Container grown plants should be re-potted every other year for good growth when new growth starts in the spring. The Ferobergia has a strong tap root, and should have a deep pot to accommodate it. This can complicate things as a deeper pot dries out more slowly.
Hardiness: Keep dry at minimum temperature of 5° C in winter, although it will tolerate brief periods down to -5 degrees.
Exposure: It should be grown in full sun to light shade.
Propagation: Seeds or graft, occasional offsets and even cuttings of tubercles (but with little success).
