Landscape Attributes
Dark Knight Caryopteris is an open multi-stemmed deciduous shrub with an upright spreading habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance shrub, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting birds and butterflies to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Planting & Growing
Dark Knight Caryopteris will grow to be about 3 feet tall at maturity, with a spread of 3 feet. It tends to fill out right to the ground and therefore doesn’t necessarily require facer plants in front. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This particular variety is an interspecific hybrid.

Dark Knight Caryopteris makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a ‘thriller’ in the ‘spiller-thriller-filler’ container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag – this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden. Be aware that in our climate, this plant may be too tender to survive the winter if left outdoors in a container. Contact our experts for more information on how to protect it over the winter months.

Want more info on sizes?
IndyPlants sells landscape size plant material. These often come in black nursery containers and are classified in sizes such as #2, #3, #5, etc. This correlates to the volume of the container, 2 gallon, 3, gallon, 5 gallon, etc. The bigger the number, the larger the pot, and the larger the plant. You’ll also see larger sizes such as 2” BB, 2.5” BB, 3” BB, etc. This stands for ‘Balled & Burlapped’. These plants are usually much larger and are not transported in black nursery pots. The sizing correlates to the diameter of the trunk of the tree.
