Compact fragrant shrubs for urban garden
We live in a DC semi-detached rowhouse. Southfacing back yard with heavily shaded side yard. We are starting to develop a planting plan and I am looking for recommendations for the most fragrant (and space efficient)shrubs---both full sun and shade-loving. Recommendations for good urban-space cultivars of lilac, sweet laurel daphne, holly (?), mock orange (will it winter in DC?)and any other ideas much appreciated.
Would like to design a sequential planting plan that ensures that some fragrant shrub is always in bloom starting in spring through the fall.
