Add composted cow manure and organic peat moss (or top soil) to the hole when you plant. Trim lightly for shape as needed and do a hard pruning in spring (late March or early April) for size and/or to encourage new growth. This plant needs a regular drink of water, though it likes the area where it's planted to drain well. Fertilize 3 times a year - in spring, summer, and autumn - with a quality granular fertilizer.
- Light Needs: Partial sun
- Watering Needs: Water regularly to maintain evenly moist soil - weekly, or more often.
This shrub is a vigorous grower with a sprawling form that often gives the plant an attractive, somewhat weepy appearance. The leaves are small and pretty for an overall fine-textured look. It blossoms with velvety flowers all year, more in warmer months. 'King's Mantle' has a rich, dark purple flower with a yellow throat. The color tends to be stronger in sun and look more blue in a bit more shade.
