In the case of M. streckeri the cephalium is much better defined and consists of dense wool and long bristles. From this cephalic zone emerge a great abundance of flowers. These are diurnal, very small in size and tubular in shape. They are brightly colored in shades of red, orange, yellow, pink and purple and have no discernible fragrance. Plants of Micranthocereus are readily propagated from seed, although cuttings are easily rooted.
All species are desirable.
All species seem to grow best in very bright light conditions, in fact, I have found container grown plants to be quite tolerant of the brutal summer heat and unrelenting sunshine of southern Arizona. The stem flowering zone has the aspect of a loose and open lateral cephalium. It branches quite freely from the base, and soon makes a nice clustered specimen. This species is particularly well adapted to growing in small containers. M. polyanthus is similar in appearance and growth habit to M. densiflorus , but the spines are straw to golden yellow with copious white wool and the flowers are a delicate pale pink with white margins.
