Hoyas form a twining plant with succulent, waxy, dark green leaves. The fragrant, starlike flowers, white or pink with a red center, are borne in thick clusters. When they drop, a spur is left behind. This should not be pruned off, since new blooms will appear at the same spot in following years.
Hoyas only begin to bloom when they are well-established in their pots, which may take two or three years. After that, they bloom faithfully each summer.
