World of CitrusHenderson Grapefruit
Rouse, Wutscher & Youtsey (2001) report that an employee of Sam Henderson, Jr. noticed a limb with stronger red blush and deeper flesh color in 1973 in a 1945-planted Everhard Nursery Ruby Red-strain orchard near Edinburg. Their account says the color persisted into April and May. This is one retrospective account; cited histories differ on the source-tree lineage, which remains unresolved.
After the Henderson mutation was recognized in 1973, Sam Henderson, Jr. granted McAllen nurseryman W. V. Ausmus the right to propagate it. Ausmus began selling Henderson grapefruit trees before the selection was brought to local research institutions.
