I have an area with North East exposure with morning and late afternoon sun. What would be the best Flowering shrub for this area bearing in mind that I need a height of about 6 feet.
Sounds like a great planting situation! Since I'm not sure of your growing zone, I would suggest a visit to your local garden center. They will have shrubs and plants that are suited to your neighborhood!
You can also contact your local County Extension Office for a list of suitable shrubs.
This is a great time of year to make selections and get them into your landscape!
