Den. Regal Vista
(Den. Regal Gillieston x speciosum)
This is a hybrid between two Austrailian-type dendrobiums. Dendrobium Regal Gilleston produces creamy yellow flowers with a blush of red and a solid red lip. Dendrobium speciosum typically is recessive for color, letting the other flower color come through.
