Pachycereus marginatus "Mexican Fence Post"
Specimen Size: 7.5"; tall by 3" in diameter.
Cactus species Pachycereus Marginatus AKA The Mexican Fence Post is the one of the most attractive and cleanest looking cacti available. The tall robust blue-green stems branch out from the cactus base to form a fence-like cluster of tall, cylindrical "posts", usually with 5 or 6 pronounced ridges. Along these ridges run symmetrical rows of small white thorns that make the Mexican Fence Post look striped from a distance. Stem growth averages 6 to 8" diameter by 20'+ feet tall.The Mexican Fence Post also produces a wonderful pink to light-red flower that adds great seasonal color to your drought tolerant cacti landscape. Because it is native to the sub-tropical areas of Mexico, the Mexican Fence Post requires a bit more irrigation than most cacti, usually weekly, during hot Southern California summers to perform its best. Fast grower!
