Dendrobium Illusion is a hybrid of Dendrobium cuthbersonii and Dendrobium lawesii. It is only 12 cm tall and has 3 cm flowers. I have three plants of this cross and this plant has the largest and most open flowers. They are also orange where the other plants have flowers that are red or red-orange.The plant is much easier to grow than either parent and tolerates warmer temperatures than Dendrobium cuthbertsonii. It is almost always in flower.
