Ideas for a long hedge
This is regarding a property in the DFW area. We have a 50' + retaining wall (grey color) along a red brick house. It gets morning sun and afternoon shade. I'm trying to decide between the following options.
(1) single plant (hydrangeas)
(2) triple layer (ornamental grass like Karl Forester in the back, hydrangeas in the middle, another ornamental grass like blonde ambition in the front)
(3) repeat group plantings
(4) create multiple rooms, say 10' for ornamental grass followed by 10' of hydrangeas, followed by 10' of salvias, etc)
What do you recommend for maximum visual impact? Also, any plant recommendations are welcome, suitable for morning son and afternoon shade, minimum upkeep, perennial, and Texas proof.
