Garden of the Month: September 2023

Posted on by

623 Prim Street

Elysian Graham and Lou Martinez bought the handsome house at 623 Prim Street in 2020 and promptly set about re-imagining the front landscape.  This is the Ashland Garden Club’s Garden of the month for September 2023.

They hired Banyan Tree Landscaping and landscape architect Lucretia Weems to do the job.  Among their primary goals were to achieve easy maintenance for their steep yard, conserve water, and be deer resistant.  They also wanted a subtle color palette, but color and interest all year, and to be pollinator-friendly.  They have achieved all this and more.

Only the large sweet gum tree on the left side of the garden and the thicket on the far right side, which is seasonally favored by deer, remain from the original yard.  Overhead sprinklers were replaced by a drip irrigation system.  The rock retaining walls and graceful stairs were added.

Ornamental grasses are highlights at this time of year and on through the winter.  As the homeowners and designers of this garden have done, the Ashland Garden Club urges gardeners to take care in choosing ornamental grasses that are not fire-prone, and to remove dead and dry growth.

The couple handle all the maintenance themselves and, as busy professionals, they are grateful that their yard is so easy-care.  Elysian particularly likes the guara and Lou likes the Japanese maple.

The Oregon Gardens

Posted on by
After years of hearing about the Oregon Gardens from garden club members, my husband and I finally visited this garden located in the charming town of Silverton, 12 miles NE of Salem, Oregon. The Oregon Gardens is a lovely 80-acre botanical garden featuring twenty themed gardens, many with water features and sculptures and it has a historic Frank Lloyd Wright house, called The Gordon House. When we arrived we first took the narrated tram tour. The driver told us the garden’s history and pointed out each featured garden and interesting facts. She explained that the wetland area in the gardens is used to cool the City of Silverton’s effluent water.  The water moves through a series of pools and is used to irrigate the gardens before it’s returned to the local river. We were impressed! After the tram tour, we purchased iced chai-tea from the Little Leaf Café in the visitor’s center, and then walked through the gardens using a brochure map to guide us.  The Conifer Garden was grand and we could have stayed here for hours, but we still had to visit: the Bosque Grove, the Sensory Garden, the Rose Garden, the Children’s Garden, the Medicinal Garden, the Garden Market Garden, the Tropical Greenhouse, and the water features. Picnicking is encouraged at the gardens, so we ate our lunch at a picnic table surrounded by trees and flowers. The garden is pet-friendly, too, there’s even a pet-friendly demonstration garden. I couldn’t leave without purchasing a plant from the retail nursery, so I bought a Dicliptera suberecta also known as a firecracker plant or hummingbird plant. This plant is a deer-resistant drought-tolerant herbaceous perennial with felty blueish-grey leaves that blooms early summer into fall. It has   clusters of tubular orange flowers that are a hummingbird’s delight!  It’s winter hardy in USDA Zone 8-10, and needs full sun. Visit the Oregon Gardens, you’ll love it. ~Carlotta Lucas Read more about the Oregon Gardens https://www.oregongarden.org/about/
