Western Least Moonwort

Botrychium simplex var. compositum

Western Least Moonwort (Botrychium simplex var. compositum) is a delicate fern that grows wild in moist grasslands, woodlands, and meadows of western North America. It has light green leaves that form a circular pattern resembling the shape of a crescent moon. Its flowers bloom in late summer and contain powdery orange spores used for reproduction. The plant is a very small species with a variable shape and height, generally between 2 and 10 centimeters. Western Least Moonwort is an endangered species due to changing environments and over-harvesting. It can easily be distinguished by its distinctive shape and size as well as its striking color.

watering

Little Grape Ferns should be watered when the soil feels dry to the touch about 1-2 inches beneath the surface. During the growing season, it is best to water lightly but consistently, providing just enough moisture to keep the soil damp but not soggy. In colder months, watering can be reduced to once a month. Avoid over-watering ferns, as too much moisture can cause the roots to rot.

sunlight

Little Grape Fern (Botrychium simplex) benefits from bright indirect sunlight, which means it should be placed near a window in an east- or west-facing room. This species will do best in areas where it's exposed to approximately 2-4 hours of sunlight daily. When kept indoors, you should make sure to rotate the plant every 4-6 weeks for even growth. It’s also important to note that the plant should be kept away from any direct sunlight to avoid burning its delicate foliage.

pruning

Little Grape Fern (Botrychium simplex) should only be lightly pruned, if necessary, around late summer or early fall. Pruning should include removing dead or damaged foliage, as well as removing any fronds that are too large and crowding the other ferns. Avoid cutting the fronds too close to the main stem, as this can cause damage. If the ferns begin to overgrow their location, divide them and replant into smaller pots or fresh soil.
