USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).

Details

The water-cleansing Rain Garden Pre-Planned Garden is both colorful and functional. By planting a colorful mix of durable perennial flowers and ornamental grasses in a depression that collects water, their roots and foliage help to filter and clean the water that percolates into the soil and recharges our aquifers. Rain gardens are a great low-tech way to take water that flows from our roofs and other hard surfaces and allows it to be slowly absorbed by the soil. This helps reduce the destructive flow of dirty storm water run-off into our streams and rivers and creates beneficial habitat using native plants. The Rain Gardens come with a planting diagram and plant care guide to create and maintain a professionally designed garden.


The large pre-planned Rain Garden covers approx. 100 sq. ft. and includes the following perennials: (3) each of Asclepias incarnata, Monarda fistulosa and Physostegia virginiana 'Crystal Peak White', (2) each of Phlox paniculata Jeana, Ratibida pinnata, Solidago rugosa 'Fireworks' and Muhlenbergia reverchonii and (1) Panicum virgatum 'Shenandoah' for a total of 18 plants.


The small pre-planned Rain Garden covers approximately 50 sq. ft. and includes the following perennials: (2) Asclepias incarnata and (1) each of Monarda fistulosa, Physostegia virginiana 'Crystal Peak White', Phlox paniculata Jeana, Ratibida pinnata, Solidago rugosa 'Fireworks', Muhlenbergia reverchonii and Panicum virgatum 'Shenandoah' for a total of 9 plants.

Rain Garden Planting Tips

Here are a few basics to help you understand the process. (See our Buliding A Rain Garden article for more detailed information.)

To create a rain garden, your perennials will be planted in a shallow depression (8 to 12 inches deep) into which run-off water drains from a roof, driveway or other hard surfaces. Test the planting area for drainage by digging a 12” wide by 12" deep hole and filling with water to saturate soil; refill in a few hours after water drains. After filling the hole a second time, the water should completely drain within 12 hours. If not, this indicates poor drainage that will require moving the garden to another site to avoid long-term standing water.

Size the rain garden's area (sq. footage) to match the sq. footage of the roof area (or other hard surfaces) that will drain into it. Be sure the depression will hold more than 1" of rainfall so it will hold enough to hold several days of rain. Here are some useful metrics to help size the rain garden depression.

Rain Garden Soil Preparation

  • Excavate the rain garden to a depth of approximately 8 to 12 inches in depth. Be sure not to leave a vertical edge, but rather a gentle slope down to the bottom.
  • Take the soil from the depression and use it to mound up the edge and create a gentle slope that slants away from the edge.
  • Rototill the bottom of the depression to a depth of 8 to 10 inches to mix in a combination of compost (1/2 to 1 cu. yd. per 100 sq. ft.) and Yum Yum Mix (4 lbs. per 100 sq. ft.) before planting.
