Light: Performs well in areas that get 4 or more hours of direct light. At the warmer end of its zone range, it does appreciate getting shade in the afternoon. This will give it the healthiest, most vibrant looking foliage.
Soil: Will grow well in most soil types, it just needs good drainage to thrive.
Water: Has average water needs. It does not respond well to any period of extended sogginess, like overwatering or heavy continuous rain events. After it is established, it would much prefer to be too dry than too wet.
Fertilizing: Nothing special is required. If desired, you may apply a granular fertilizer formulated for flowering woody plants in late winter/early spring when the soil is workable.
Pruning: Regular pruning is not recommended. It has an elegant, arching habit that is best left to grow naturally. However, periodic rejuvenation pruning every 3 to 5 years can be helpful to keep the plant flowering well. This is the process of removing the oldest, thickest branches all the way back to the ground. This promotes juvenile growth which will flower most prolifically.
Other: It’s related to popular plants Weigela and Diervilla. You might see a connection between these plants in their arching habits.
