Western Moonwort

Botrychium hesperium

Also Known As - Grapefern
Western Moonwort (Botrychium hesperium) is a species of fern native to Western North America. It grows to about 7 inches in height with several light-green, divided fronds per stem. The short, erect rhizomes are covered in brown scales. Its pale yellow to pinkish spore-producing sporangia appear in early summer and are arranged in a fan-shape along the margins of the leaflets. The stems and foliage of this small plant are prone to drying out under drought conditions. Western Moonwort prefers moist, shaded areas near rivers and streams and is a popular choice for shady gardens.

watering

Scalloped Moonwort requires minimal water to survive. It's important to keep the soil slightly moist, never allowing it to become waterlogged or overly dry. It's best to water your plant about once every 5-7 days, allowing the soil to dry out between waterings. If the soil looks dry, then add the appropriate amount of water - usually approximately 1/2 cup - until the top 1-2 inches of soil are moist. Drain any standing water that has accumulated in the saucer. During dry periods, it's best to increase watering frequency slightly, but without letting the soil become soggy.

sunlight

Scalloped Moonwort is an alpine species of plant that prefers moist, cool soil in partial shade to light shade. It requires medium to low levels of sunlight, so no more than 4-6 hours per day. Exposure to more intense or direct sunlight can cause the leaves to become scorched and the plant to dry. When grown in sunny locations, it is important to provide adequate moisture, such as through consistent watering or a layer of mulch.

pruning

Scalloped Moonwort (Botrychium crenulatum) does not require pruning to maintain its form. This type of fern does not produce vertical growth and instead spreads steadily outward, making pruning unnecessary for controlling size and shape. However, periodic pruning can help rid the plant of dead or diseased fronds. Therefore, it is recommended to prune Scalloped Moonwort only as needed, usually in late winter when the plant is dormant.
