Scalloped Moonwort

Botrychium crenulatum

Also Known As - Wavy Moonwort
Scalloped Moonwort (Botrychium crenulatum) is an uncommon species of fern-like plant. It is smaller than most other ferns and grows only up to 8cm tall with thin leaves that can have either 3 to 9 fronds or leaflets. Its lacy, scalloped leaflets grow off of blade-like stems and the plant produces an insignificant yellowish-brown flower in early summer. Its habitat consists of grassy mountain meadows and lowland hillsides, and prefers damp, shaded soil and partial sunlight. It is a rare species that is threatened by human development and thus is considered endangered in some areas.

watering

Boreal Moonwort (Botrychium boreale) is best kept moist and should be watered deeply, approximately twice a month. During the summer months, it is important to avoid over-watering, as excessive water can result in the plant's cells becoming waterlogged and the roots drowning. During the dry season, ensure that the soil remains adequately moist, but not overly wet. Water once in a while, making sure the soil is allowed to dry out in between waterings. In the wintertime, the frequency of watering should be drastically reduced. The Boreal Moonwort is a drought-tolerant species that can survive with less water, so only water when the soil has completely dried out, about once every 3-4 weeks.

sunlight

Boreal Moonwort thrives in dappled shade, preferring bright indirect light. It will tolerate exposure to direct morning sun, but no more than an hour per day, and should be protected from the hottest midday sun. This plant species requires 8-10 hours of sunlight daily during the growing season and prefers morning sun during the summer months. During colder months, it should be given 5-6 hours of sunlight each day. Unfortunately, it will not tolerate very long days of continuous light and shading may be necessary.

pruning

Pruning is rarely necessary for this species, since it is so low-maintenance. However, if desired, selective pruning can be done in late spring (April/May) to remove any dead, diseased, or damaged stems. Any pruning should be minimal – only remove stems when absolutely necessary. Over-pruning can result in thin, sparse foliage which can reduce the plant’s health.
