Title: Fasciation on Texas Mountain Laurel
Answered by: Nan Hampton

QUESTION:

Do Texas Mountain Laurel normally have a staghorn looking growth hanging on them after blooming in addition to the seed pod clusters or could this be a mutation?

ANSWER:

The staghorn growth you are seeing on the Sophora secundiflora (Texas mountain laurel) is called a fasciation.  Fasciation is a plant developmental anomaly in which it appears that stems, flowers, leaves and/or fruits have been fused. It is uncertain whether it is genetically determined or caused by disease or some other sort of trauma to the plant. It does appear that there may be an inheritable tendency toward fasciation that may be triggered by environmental conditions such as temperature, crowding, insect attack, disease or wounding of the plant. Texas Mountain Laurel seems especially susceptible to fasciation.  Here are photos photos of fasciated plants and more information from Purdue University Extension and Colorado State Extension and some photos of fasciated, or cristated, cactus (cristation is a synonym for fasciation).

Below are photos of fasciated stems of Texas Mountain Laurel and a fasciated blossom of Lupinus texensis (Texas bluebonnet).
