Is Caryopteris Dark Knight a perennial?
Caryopteris x clandonensis ‘Dark Knight’ Plant Description: This is a nice 2-3 ft tall and wide perennial/shrub. It is best treated as a perennial along the Wasatch by being cut back each year. Caryopteris can be propagated by cuttings taken during spring or early summer. Find non-flowered shoots 5-10cm long and snip off the plant. Put them in a plastic bag straight away to prevent drying out. Fill a container with a compost mix which is at least 50% perlite (or if you prefer, as we do, 100% perlite).One of the most significant advantages of Caryopteris plants is that they are low-maintenance and easy to care for. They require minimal pruning and can survive drought conditions. In early spring, prune back any damaged or dead branches.Caryopteris is fast growing. Once established, it can grow about 18′ – 30′ a year, though it usually tops off at about 3′ in height. Older stems will become woody, giving it a little structure. The signature blue blooms will only occur on new growth, so pruning is necessary.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.Plant Caryopteris in a sunny, well-drained spot—it’s not tolerant of wet or heavy soils, especially in winter. Improve drainage before planting if needed by adding grit or organic matter. These small, deciduous shrubs prefer a sheltered site and do best against a warm wall or in a border that gets plenty of sun.
Is a Caryopteris a perennial or shrub?
Hardiness: Hardy in USDA zones 5 through 9, Caryopteris are soft-wooded shrubs or subshrubs that behave more like herbaceous perennials than like woody shrubs. Caryopteris × clandonensis, commonly called bluebeard, blue spirea or blue mist, is a low-mounded, deciduous shrub that is valued for its aromatic foliage and late summer flowers which are said to resemble clouds of blue smoke or mist.
Is Caryopteris short-lived?
It may develop some woodiness however it grows from the ground up each spring and blooms in late summer on new softwood growth. What is the lifespan of a Caryopteris? This is a short-lived plant lasting from three to five years before replacement is needed. Caryopteris are easy to propagate. In the spring, you can divide the offshoots from the main bush or you can take soft wood cuttings. I have also read that it disperses seeds, but I have never seen seedlings.Caryopteris should be pruned every spring to keep them compact and flowering strongly. They can also be pruned lightly after flowering.Prune caryopteris in spring. As it flowers on the current year’s stems, cut back hard in spring to encourage new growth. Wait for the first signs of leaves emerging, and then cut back to pairs of strong buds on the woody frame.
