Stanhopea shuttleworhtii x grandiflora

A new primary hybrid, which has also been oryzalin-treated in the lab for potential tetraploid conversion. In other words, we are trying to make already large flowers even larger! Big, showy, and fragrant is the goal with this cross.

These are established seedlings in 4-inch production pots and are expected to reach blooming size in 2027–2028. The hanging baskets, however, have the potential to bloom as early as the summer or fall of 2026.
