CRISPATE: Curled or rippled at the edge such as the leaves of Pittosporum eugenioides. Also crisped.
CROCKS: Broken pieces of clay pot, used to cover drainage holes of pots in order to provide free drainage and air circulation to the root system and to prevent the medium (i.e. soil) from washing down the holes.
CROSS: 1. To produce a hybrid plant by cross-fertilizing individuals of different varieties or species. 2. A hybrid produced by cross-fertilization.
CROSS-FERTILIZATION: The fertilization of the ovules of one flower by the pollen of another, either between plants of the same species or between individuals of different species, resulting in the production of a hybrid.
