How to Know When the Seeds in a Peace Lily Are Ripe

Although the peace lily (Spathiphyllum) likes tropical heat, it doesn't do well in the sun. The plant thrives indoors or in a shady spot outside as long as the air is moist and warm. The dark green and lustrous peace lily foliage sprouts from the ground without a stem and can reach 5 feet tall in ideal condition. Numerous tiny flowers grow on a spike called a "spadix." A white petal-like structure, known as a bract or spathe, develops around the spadix and is commonly referred to as the peace lily flower. Once pollinated, the plant also produces a fruit resembling a desiccated berry, which holds the seeds.

Instructions

- 1
  Observe the spadix every day to determine when pollination is occurring. The flowers along the spike will develop a shine and release some fluid. Touch them. If they feel sticky, they are about to be pollinated. Just before the pollen is released, the flowers become dry and brown. Peace lilies produce bisexual flowers. Fertilization occurs without pollinators or another plant's presence.
- 2
  Count four months from the day you notice pollen, a yellow powdery substance, on the flowers. Pollination lasts three to four days on this plant. The peace lily fruit and its seeds ripen four to six months after pollination.
- 3
  Consider the peace lily seeds ripe when the plant's spadix, originally a stiff structure, becomes soft and yellow.
