Sorbus americana aka Mountain Ash

Taxonomy

The American mountain-ash, scientifically known as Sorbus americana, is a deciduous perennial tree native to eastern North America. It is commonly referred to as the American mountain-ash or rowan tree, which is also used to describe related species like the European mountain-ash (Sorbus aucuparia). This slow-growing tree features a rounded crown and light green leaves composed of up to 15 leaflets that turn red or yellow in the autumn. In late spring and early summer, it produces dense clusters of small white flowers, followed by orange-red berries. The American mountain-ash typically reaches heights of 15-30 feet and has smooth, gray bark that becomes scaly with age. Its attractive form, white spring flowers, serrated compound-pinnate leaves, and bright orange-red fall fruit make it a visually appealing choice. The berries, although too acidic for human consumption, are enjoyed by birds and animals and can be used to make jellies. Despite their name, mountain ashes are part of the rose family and not related to true ashes.

How to care for Mountain Ash

Difficulty

Mountain Ash presents a moderate level of care, which allows plant enthusiasts with some experience to expand their skills and knowledge.

Water

Mountain Ash should be watered regularly, allowing the soil to dry out between waterings.

Soil

Mountain Ash loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

Lighting

Mountain Ash thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Dogberry.

Toxicity

Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.

Fertilizer

The growth of Mountain Ash is gradual and it doesn't necessitate any additional fertilizers. Replacing the soil in its pot once a year should suffice to provide the plant with sufficient nutrition. It's important to keep in mind that plants derive their energy from the sun's rays, not fertilizers.

Region of origin

Mountain Ash’s native range is Eastern N. America - Newfoundland to N. Carolina, west to Illinois and Manitoba.
