Gro-Low Sumac (Rhus aromatica 'Gro-Low') - Pollination Info

The Gro-Low Sumac, scientifically known as Rhus aromatica 'Gro-Low', is a low-growing deciduous shrub native to North America. It produces small yellow flowers in early spring, which are key in attracting pollinators. Here is some detailed information about its pollination:

Pollination Mechanism

The flowers of Gro-Low Sumac are primarily pollinated by insects, especially bees and butterflies. These insects are attracted to the nectar and pollen of the flowers. As they land on the flowers to feed, they inadvertently transfer pollen from the male reproductive parts (stamens) to the female reproductive parts (pistils) of the same or different flowers, leading to fertilization.

Flowering Time

Gro-Low Sumac typically blooms in early spring, usually between March and May, depending on the region and climate. The flowering period lasts for several weeks, providing ample opportunity for pollinators to visit and effectively transfer pollen.

Pollinator Attraction

The bright yellow flowers of Gro-Low Sumac are highly attractive to a wide range of pollinators. Bees, including honeybees and native solitary bees, are particularly fond of the nectar and pollinate the flowers while foraging. Butterflies, such as swallowtails and hairstreaks, also visit the flowers, sipping nectar and inadvertently aiding in pollination.

Pollen Dispersal

The pollen of Gro-Low Sumac is dry, powdery, and easily dispersed by wind. However, since the flowers are primarily insect-pollinated, pollen transfer by wind is thought to be less significant compared to insect-mediated pollination.

Importance for Wildlife

In addition to supporting pollinators, Gro-Low Sumac also provides attractive fruits for birds. After successful pollination, the flowers develop into small, reddish drupes that persist through the summer and into fall, serving as an important food source for birds during migration and winter. The fruits are rich in nutrients and are consumed by various bird species.

Pollination Requirements

Gro-Low Sumac is a self-compatible plant, meaning it can produce fertile seeds even without cross-pollination from other plants. However, cross-pollination between individual shrubs can enhance genetic diversity and seed production. To ensure optimal pollination and fruit set, it is recommended to have multiple Gro-Low Sumac plants in close proximity.

Pollinator-Friendly Practices

To further support pollinators and maximize pollination success for Gro-Low Sumac, consider implementing pollinator-friendly practices in your garden. These can include providing additional nectar sources such as other flowering plants, avoiding or minimizing pesticide use, and creating habitat features like shelter and water sources for pollinators.

FAQ for Gro-Low Sumac (Rhus aromatica 'Gro-Low')

1. What is Gro-Low Sumac?

   Gro-Low Sumac (Rhus aromatica 'Gro-Low') is a low-growing shrub that belongs to the Anacardiaceae family. It is a cultivar of the Fragrant Sumac. It is known for its dense spreading growth habit and aromatic foliage.

2. What are the characteristics of Gro-Low Sumac?

   Gro-Low Sumac typically reaches a height of 2 to 3 feet and spreads up to 6 to 8 feet. Its branches are densely covered with trifoliate leaves that turn attractive shades of orange, red, and purple in the fall. It produces small clusters of greenish-yellow flowers in spring, followed by red fruits that persist into winter.

3. Where can I plant Gro-Low Sumac?

   Gro-Low Sumac thrives in full sun to partial shade conditions. It prefers well-drained soils but can tolerate a wide range of soil types, including clay and sandy soils. It is fairly drought-tolerant once established and can withstand harsh environmental conditions.

4. How do I care for Gro-Low Sumac?

   Gro-Low Sumac is a relatively low-maintenance plant. Here are some care tips:

   • Water regularly during the first year to help establish a strong root system.
   • Apply a layer of organic mulch around the base of the plant to help retain moisture.
   • Prune dead or damaged branches in late winter or early spring before new growth begins.
   • Fertilization is usually unnecessary, but a general-purpose, balanced fertilizer can be applied in early spring if desired.
   • Keep an eye out for any signs of pests or diseases and take appropriate action if necessary.

5. Can Gro-Low Sumac be used as a groundcover?

   Yes, Gro-Low Sumac is often used as a groundcover due to its low-growing, spreading nature. Its dense growth habit helps to suppress weeds, and its attractive foliage adds visual interest to the landscape.

6. Is Gro-Low Sumac deer resistant?

   Yes, Gro-Low Sumac is considered to be deer resistant. Its foliage contains compounds that are unpalatable to deer, reducing the likelihood of deer damage.

7. Can Gro-Low Sumac be propagated?

   Yes, Gro-Low Sumac can be propagated through softwood or hardwood cuttings. Softwood cuttings are best taken in early summer, while hardwood cuttings are taken in late winter or early spring. It can also be propagated through division or by layering.

Gro-Low Sumac (Rhus aromatica 'Gro-Low')

The Gro-Low Sumac, also known as Rhus aromatica 'Gro-Low', is a low-growing shrub that thrives in various soil conditions and is known for its vibrant fall foliage. Here are some planting and care tips to ensure the healthy growth of your Gro-Low Sumac:

Planting:

• Choose a sunny or partially shaded location for planting.
• Ensure the soil is well-draining to prevent waterlogging.
• Dig a hole that is slightly larger and deeper than the root ball of the plant.
• Place the Gro-Low Sumac in the hole, making sure it is at the same level as the surrounding soil.
• Backfill the hole with soil, gently firming it around the base of the plant.
• Water thoroughly after planting to help settle the soil.

Care:

• Water regularly during the first year to establish the plant. Afterward, the Gro-Low Sumac is drought-tolerant and only requires watering during prolonged dry periods.
• Apply a layer of organic mulch around the base of the plant to help retain moisture and suppress weed growth.
• Prune the Gro-Low Sumac in late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing branches to maintain a healthy shape.
• Fertilizer is generally not necessary for this plant. However, if desired, a slow-release balanced fertilizer can be applied in early spring.
• Monitor for common pests such as scale insects or aphids. Treat any infestations promptly using appropriate methods.
• In areas with harsh winters, protect young plants from frost or freezing temperatures by applying a layer of mulch around the base.
• Enjoy the beautiful fall color of the Gro-Low Sumac, which turns vibrant shades of red, orange, and yellow.

By following these planting and care instructions, you can ensure the healthy growth and beautiful appearance of your Gro-Low Sumac.
