Landscapes, and the plants we find in them, are evolving milieus that reflect the changes in atmospheric and ground temperatures, duration of daylight, and amount of precipitation among other things. This becomes most evident to us as the seasons change, and natural things begin to ready themselves for the months ahead. The gardens at the New Norris House all serve an ecological function, whether it is to filter rainwater, remediate greywater, or reduce heat island effects. However, plants were chosen not only for their functionality, but also for their year-round beauty. The planting design reflects this as different species were grouped and located in relation to each other based on when they bloom or have interesting foliage.
The uppermost image shows the changes in the landscape palette at a conceptual level, while the above chart provides a monthly sequence of interest. An example, the below image shows two native grasses. While both grasses have a cool green to blueish tint in the spring and summer, Panicum virgatum 'Shenandoah' (in backgorund) develops burgundy streaks in the fall. When Schizachyrium scoparium 'The Blues' (foreground) is planted next to Panicum its airy, golden blooms form a fantastic complimentary relationship that is only evident in the fall.
Anyone want to go on a plant walk?
The grasses in the parking court bed are my favorite plant around the house right now. Their colorful glow is beautiful!
