Caryopteris x clandonensis Beyond Midnight® Bluebeard

Beyond Midnight® is the trade name for Caryopteris × clandonensis ‘CT-9-12’, bred by Gavriel Danziger. The Canadian variety record identifies the exact trade name and denomination, and U.S. Plant Patent 27,426 documents the cultivar’s compact growth and shiny leaves. ## Form and flowering Spring Meadow describes this cultivar as an upright, compact bluebeard with deep blue flowers in the late-summer garden. Its page also identifies bees, butterflies, and hummingbirds visiting the flowers. The [patent](https://patentimages.storage.googleapis.com/7d/3c/cf/0a539fd38670a3/USPP27426.pdf) reports 64 cm height and 92 cm spread in 2–3-year-old plants under its trial conditions; Spring Meadow lists mature height and spread of 24–30 inches. The catalog’s existing 24–30 inch dimensions are retained because these published measurements vary by age and setting. ## Siting Use the shrub in a sunny border or pollinator planting with well-drained soil. The [CFIA record](https://active.inspection.gc.ca/english/plaveg/pbrpov/cropreport/blueb/app00009738e.shtml?wbdisable=true) confirms the selection code and finds it narrower than Dark Knight in a comparative trial. ## Mature size The breeder’s garden guidance is 24–30 inches tall and wide; the patent’s container-grown measurements describe older plants in a different setting. Allow room for its upright stems and rounded spread. ## Maintenance Water new plantings until established. Spring Meadow describes drought tolerance after establishment and recommends well-drained soil; no cultivar-specific pruning date is given in the reviewed sources.
