Odora

Porophyllum gracile

Porophyllum gracile, commonly known as slender poreleaf, slenderleaf poreleaf, and odora, is a beautiful and unique addition to any low desert pollinator garden. This plant is native to the southwestern United States and northern Mexico and blooms in the late summer and early fall, providing a late-season nectar source for pollinators.

Slender poreleaf is part of the Asteraceae family and can grow up to 2 feet tall and 3 feet wide, making it a great choice for adding structure and volume to a garden bed. This plant thrives in full sun and well-drained soil, making it a perfect fit for the hot and dry conditions of the low desert.

One of the benefits of Porophyllum gracile is its low watering needs. This plant is drought-tolerant and can survive on minimal watering once established, making it an excellent choice for water-wise gardens. However, it is still recommended to water this plant every 1-2 weeks during the growing season to ensure its health and blooming success.

In addition to its ornamental value, Porophyllum gracile also provides numerous benefits to wildlife. Its small, daisy-like flowers attract a variety of pollinators, including bees and butterflies, and its foliage can serve as a host plant for caterpillars.

When planning a low desert pollinator garden, it’s important to include a variety of plants that bloom throughout the growing season. With its late-season blooms, drought-tolerant nature, and wildlife benefits, Porophyllum gracile is an excellent choice for any garden looking to attract and support pollinators.
