Bay Willow Salix pentandra
ABOUT
Salix pentandra, also commonly known as the bay willow, is a plant distinguished by its shiny, dark green leaves that exude a fragrant aroma reminiscent of bay leaves. The leaves are lance-shaped with finely serrated margins and a glossy, almost leathery texture. Bay willow produces catkins, which are spike-like clusters of flowers with no petals. These catkins appear in late spring and early summer. The male catkins are typically yellow due to the presence of pollen, while the female catkins are greener and will eventually develop into small capsules containing the seeds. Bay willow is also recognized for its attractive bark which is smooth and gray when the plant is young but gradually develops deep furrows with age. The branches are often flexible and have a yellowish or brownish tint. Overall, bay willow presents a lush, dense canopy of foliage that can provide a rich, verdant appearance in the landscape.

- Toxicity
To humans
Bay willow, which is the most common common name for Salix pentandra, is not generally considered toxic to humans. The ingestion of parts of this plant typically does not result in poisoning and significant symptoms are not common. Salix species, in general, have been used medicinally and contain salicin, which is related to aspirin, but the use of bay willow specifically for such purposes is less well documented. As with any plant, individual allergies or sensitivities might exist, and consuming parts of the plant not typically meant for ingestion, such as wood or bark, might cause mild stomach upset, but significant toxicity or severe consequences are not commonly associated with this species.
To pets
Bay willow is also not generally known to be toxic to pets such as dogs and cats. Similar to humans, ingestion of parts of Salix pentandra is unlikely to cause significant poisoning in household pets. Some animals might experience mild gastrointestinal upset if they consume large quantities of leaves, stems, or bark due to the fibrous plant material rather than specific toxic compounds. Nevertheless, it's always prudent to monitor your pets around plants and discourage them from chewing on any that aren't explicitly safe, as individual animals could have unique reactions.

- Water
The Bay Willow, commonly known as Salix pentandra, thrives in moist conditions and requires regular watering. To keep the soil consistently moist, water the plant with about 1 gallon of water once or twice a week during dry periods. During the growing season, particularly in hot summer months, you might need to water the plant more frequently to maintain soil moisture. In contrast, during the dormant winter season, reduce watering to when the soil feels dry to the touch to avoid waterlogging. Always check the top few inches of soil for dryness before watering.
- Light
The Bay Willow does best in full sunlight where it can receive at least six hours of direct sunlight daily. An ideal spot would be an open area away from taller structures or trees that might create significant shade. However, it can tolerate partial shade, particularly in hotter climates where some relief from the intense afternoon sun can be beneficial.
- Temperature
For the Bay Willow, the ideal temperature range is between 35°F and 75°F. The plant can survive in temperatures as low as -30°F and as high as 90°F, but extreme temperatures may stress the tree. This hardy species is adaptable to a wide range of climate conditions but performs best when conditions are within the aforementioned ideal range.
- Pruning
Pruning the Bay Willow is primarily done to maintain shape, remove damaged limbs, and encourage healthy growth. The best time to prune is late winter to early spring, before new growth begins. Aim to thin out overcrowded branches and remove any dead or diseased wood annually. Severe pruning should be spaced out over multiple years to avoid stressing the tree.
- Cleaning
As needed
- Soil
Bay willow thrives in moist, well-drained loamy soil with a pH between 5.5 and 8.0. A mix of garden soil, peat, and sand in equal parts is ideal to ensure proper drainage and fertility.
- Repotting
Bay willow, being a large tree, is not commonly repotted. It's typically planted directly in the ground where it has space to grow. If grown in a container, upgrade to a larger pot when the root system outgrows the current one, which may be every 2-3 years.
- Humidity & Misting
Bay willow prefers high humidity levels but is adaptable to a variety of humidity conditions typical of outdoor environments. Aim for 50-70% relative humidity if grown in a controlled indoor setting.
- Suitable locations
Indoor
Grow Bay willow in large containers with ample light and water.
Outdoor
Plant in moist, well-drained soil; full sun to partial shade.
Hardiness zone
4-8 USDA
- Life cycle
Salix pentandra, commonly known as bay willow, begins its life cycle when its tiny seeds, which are dispersed by wind or water, germinate in moist soil during spring. The seedlings go through a juvenile phase, developing a root system and a stem while leaves start to photosynthesize to provide energy for growth. As the plant matures, it enters the vegetative growth stage, forming a shrubby or treelike structure with glossy, lance-shaped leaves. Bay willow is dioecious, meaning individual plants are either male or female; it reaches reproductive maturity after several years, producing catkins (flowers) in late spring which are pollinated by insects. After pollination, the female catkins develop into tiny capsules that release seeds, completing the reproductive cycle. The bay willow, being a perennial, can live for many years, continually growing and producing new seeds annually.
- Propogation
Propogation time
Spring
The Salix pentandra, commonly known as Bay Willow, is often propagated through hardwood cuttings. This method is popular for its simplicity and effectiveness. For optimal results, the cuttings are usually taken during the plant's dormant season, which is late fall or winter. Branches of Bay Willow are selected—preferably those that are about one year old and have reached a diameter of roughly 1/4 to 1/2 inch (approximately 6 to 12 mm). Cuttings about 6 to 8 inches (15 to 20 cm) in length are then snipped off and planted directly into moist soil where they will readily root. It is crucial to keep the soil consistently moist until the cuttings develop strong root systems and start to show new growth, indicating successful propagation.
