Nopalxochia phyllanthoides or Pond-Lily cactus is an epiphytic cactus native to Southern Mexico. It has flat, saw-edged stems that will reach 18 inches in height with a 2 foot spread in hanging baskets. It is one of the easiest of the jungle cacti to grow.
Blooming Time: Late winter - early spring. The flowers emerge from the teeth of the stem and resemble water lilies when they are open.
Culture: Nopalxochia phyllanthoides need warm temperatures and bright light, but not direct sunlight. We grow ours under 52% shade all year. Suitable compost consists of 1 part peat moss to 1 part pine bark to 1 part sand or perlite. It needs regular watering from May - October and should be fertilized on a monthly basis during this time. Winter temperatures should be kept at 50° for flower development. Water sparingly in the winter months. When the flower buds are 1 inch long, move the plant to a warmer environment for a spectacular flower show. Water and fertilizer should resume at this time. Re-pot into a slightly larger pot after flowering.
Propagation: Nopalxochia phyllanthoides are propagated from stem cuttings taken in May after flowering.
