Pieris Japonica

Posted on by

This is a Pieris Japonica I bought at the Jackson County Master Garden Fair in a one gallon container about 7 or 8 years ago. The new growth is always this stunning pink color. At first, when I saw it I thought it was a cross between a Pieris and an Azalea. ~ Jeanne Arago, AGC Member

April 2020: Garden of the Month:

Posted on by

467 Scenic Drive

The lovely garden at 467 Scenic Drive is the Ashland Garden Club’s Garden of the Month for April. It is a work-in-progress by homeowners Elaine Yates and Michael Costello who have had this property for 3.5 years. Although the yard had good bones, with handsome hardscape and fruit trees, the garden had been greatly neglected in recent years. They removed several diseased or dead trees which has opened things up for new additions with an emphasis on blooming plants.

 Elaine is the primary gardener and designer, but Michael contributes. He rebuilt an impressive set of raised beds for edibles in the side yard as well as choosing and placing a new wisteria. Having moved to Ashland from the Bay area, Elaine has had a steep learning curve with new weather patterns to understand and more aggressive deer than she was accustomed to. On the plus side, she has been happy to discover the multitude of bees and other pollinators and the wonderful profusion of blooming plants that thrive here. She spends anywhere from three to five hours per week in the slow season (Winter) to ten to twelve hours per week the rest of the year.

 Heathers, grape hyacinths, forsythia, azaleas (in the deer-proof back yard), and rosemary are the stars right now but soon the rhododendrons will burst forth so Elaine encourages readers to delay until late in the month or early next month visiting to admire the garden from the street.
