Fraxinus pennsylvanica aka Green Ash

Taxonomy

Genus Fraxinus Family Oleaceae Order Lamiales Class Magnoliopsida Phylum Tracheophyta
Fraxinus pennsylvanica, also known as green ash or red ash, is a fast-growing, deciduous tree native to eastern and central North America. It can be found from Nova Scotia to Alberta and Colorado, and southward to Florida, Oklahoma, and Texas. This adaptable tree has also become naturalized in the western United States and parts of Europe. Other less common names for Fraxinus pennsylvanica include downy ash, swamp ash, and water ash. When young, this tree has a narrow habit, but it can grow up to 18 meters tall. It features downy shoots and green leaves that emerge late in spring. The leaves turn vibrant shades of yellow, red, and burgundy in autumn and persist on the tree longer than other selections. In spring, it produces inconspicuous, pale, petalless flowers, but does not produce fruit. Green ash trees are highly resilient and adaptable, making them popular choices for urban landscapes. However, they are now susceptible to the devastating emerald ash borer (EAB) infestation, which spreads rapidly. Before introducing a new green ash to an area, it is essential to check local regulations and consider the potential consequences. In some cases, the tree may need to be removed to prevent the spread of the disease to nearby trees.

Common names

Green Ash, Red Ash, Downy Ash, Northern Red Ash

How to care for Green Ash

Difficulty

Green Ash requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Water

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

Soil

Green 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

Green Ash requires abundant, bright and direct light. Placing it less than one foot from a window is the best way to make sure the plant receives enough light to survive and thrive. Depending on your region, however, the current weather can affect the placement of the plant in your home. For example, in some areas the sun may be too direct and intense, so it's best to place it farther away from the window. You may also need to adjust your placement according to the season as the sunlight can change intensity over the course of the year. If you live in a region with significant temperature fluctuations, such as a desert, you may need to place the plant a bit farther away from the window to avoid extreme heat or cold. With some care and attention, your Green Ash will be sure to bring you many years of beauty and enjoyment.

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 Green Ash should be transferred to a new pot once it has increased in size two-fold, or on an annual basis, whichever occurs earlier. Replacing the soil with fresh potting soil containing all the necessary nutrients, is sufficient enough to support the growth of the plant, thus avoiding the need to use fertilizer. It's important to note that plants derive their energy from the sun and not fertilizer.

Growth-pattern

New growth will sprout from the top of the plant as it grows upwards.

Region of origin

Green Ash’s native range is Eastern N. America - Nova Scotia to Alberta, south to Florida and Texas.
