Caryopteris x clandonensis (Blue Mist Shrub) [15 Seeds]
Germination Information: If you are looking for a blue mist shrub with a specific flowering trait or growth habit, you’re better off purchasing a plant of a named cultivar. If you’re okay with a bit of color and size variation, though, growing from seed can produce good-looking plants too. I recommend these seeds for experienced seed-starters only, however, because they may require some patience.
The easiest approach is to purchase and surface-sow (do not cover) the seeds in a pot fall to early winter, setting them outdoors in a spot protected from mice so they can get a chilling period and then germinate when conditions are right in spring.
If you sow after January, consider giving the pot an artificial chilling period of 2 to 3 months.
It is possible that these seeds could germinate if you sow them in warm, moist, bright conditions. But if you try that and no seedlings appear within 3 to 4 weeks, then try the artificial chilling period.
Note that this information will not appear on the seed packet you receive.

Blue mist shrub (Caryopteris x clandonensis) produces bushy plants typically 3 to 4 feet tall and wide, with aromatic, gray-green leaves and whorls of blue flowers that bloom in late summer to early fall. Commonly grown as a perennial but technically a deciduous shrub, it is a favorite with bees, butterflies, and other pollinators. The seedheads are somewhat interesting too, and if you leave them on the plant into the winter, you’re likely to find some self-sown seedlings in future years. I suggest cutting all of the stems back to about 1 foot soon after you notice new growth appearing in spring to keep established plants neat and bushy. Full sun. Zones 5 to 9.
2021-collected seeds sold out. I hope to collect again in October 2022. At least 15 seeds.
