Title: Plants for the north side of the house in Norborne MO
Answered by: Barbara Medford


What perennials, plants, flowers, are best suited for north side of house?


In questions about the orientation of a garden, the important consideration is the sun exposure to the area. If the plantings are out in the open, away from where they would be shaded by the house, other structures or trees, it really wouldn't matter, as long as the plants were native to the area and therefore accustomed to the climate, soils and rainfall. In the Northern Hemisphere, in the winter, the sun has dropped down toward the southern horizon, which means that plants close to the house will be in shade a good part of the year. The best way to make a decision on the amount of sun in an area is to keep records on what parts of the garden are in sun, how much sun and what times of the year. You likely don't want to wait to get such a thing done, so you need to make a judgment based on how close your plants would be to something that makes shade in the winter. In the summer, when the sun is more nearly overhead, a building will not cast much shade, although a wing, fence or garage could cause shade, even then.  If you have been on the property for a while, you probably already have a good idea. Our definition of "sun" is 6 hours or more of sun a day, "part shade" is 2 to 6 hours a day, and "shade" is less than 2 hours a day. 

Once you have defined for yourself which are your sun, part shade and shade areas, you can select plants native to your area of Carroll County, knowing that they will already be adapted to the environment, as long as their light requirements are met.  We will demonstrate how to do this by going to our Native Plant Database, Recommended Species, click on Missouri on the map. From there we will make separate searches on General Appearance, "herb" (herbaceous flowering plants,) with Light Requirements successively of sun, part shade and shade. Following the same procedure, we will select shrubs, trees and grasses. You can repeat this process, inserting indications of your Soil Moisture as well. We will check that each plant we select is native to your area. It probably will help you, when you are selecting plants, to make a rough sketch of the area, indicating sun, part shade and shade areas. When you read the list we are making, follow the links to the page on each individual plant to learn expected size, whether it is annual or perennial, evergreen or deciduous, growing conditions and propagation instructions.
