Proven Perennials for any Garden!
June 2009

Perennials make a great addition to any type of garden. Whether you have a hillside or a low area where water collects, a dry sunny bed or a shady spot, perennials are a perfect solution! Perennials return year after year bringing color, texture and form to your garden

(Plants subject to availability)

Perennials that work on hillsides
If you have a steep hill and have problems with erosion or are just tired of mowing, perennials are your answer!

There are many choices for a sunny hillside. Sedum is easily grown in average, dry to medium, well-drained soils in full sun. They will tolerate some light shade as well as drought and heat. Sedum thrives in sandy to gravelly soils of moderate to low fertility. They prefer good soil drainage to perform well. Plants will naturalize over time.

There are dozens of species that range from large garden flower hybrids to tiny species that creep along the ground. Each has some variation of color and texture. Try a combination of the various sedums for texture, color and low maintenance.

Consider some of the Stepables such as Archers Gold, Creeping or Wooly Thyme, Creeping Jenny or Mazus reptens for a sunny hill. Try some of the lower growing grasses such as Black Mondo Grass or variegated Liriope for low maintenance and a stunning look.

For a shady hill mix wild Canadian Ginger, a lovely low ground cover with the 2009 Plant of the year, Hakonechola macra 'Aurela,' Ajuga or any of the many wonderful Hostas.

Love flowers, but don't want the high maintenance? Use Native Plants or Xeriscaping
Using native plants for lower maintenance gardening and water conservation. By using native plants in good healthy soil, you will eliminate the need for fertilizers and pesticides. By reducing the amount of turf grass, you will save money and fuel! And, you will create a habitat for local wildlife.

Almost any landscaping style can be achieved using xeriscaping. The principles can be applied to all or part of a yard, in any geographic region.

We suggest some of the following grasses and perennials for a native landscape in a sunny area:
