Stenocereus alamosensis has 5 to 8 sinuous ribs, areoles are 1.-1/4" to 2-1/2" apart or (3-4 cm). Spines average 1 to 8 centrals up to 1-1/4" inch long or (3 cm) with 11-18 radials that are reddish at first in color later turning greenish. Easy to grow if planted in a frost free location. Almost no water use once established. The bright red flowers will attract many hummingbirds to the cactus garden.

More Info. : Stenocereus alamosensis is viviparous meaning that the seeds will germinate before leaving the parent plant, apparently this is an adaptation to living in coastal plains areas which are prone to flooding.
Care : Stenocereus alamosensis is very drought tolerant once well established. Takes full sun and average to semi-rich good draining soil. Give some protection from full sun for small seedlings. Can be frost tender especially small plants so give protection in frost prone areas. Hardy to 32 degrees for only very brief periods if well established plants. Keep 1 to 2 year olds at 50 degrees or higher. Although not required to survive you can water more often in mid-summer to speed up growth. If you are located in a cold climate this species adapts very well to a warm and brightly lighted greenhouse.
