Cryptomeria japonica 'Black Dragon' / black dragon Japanese cedar

Cryptomeria japonica 'Black Dragon' gets its name from its dark green needles that, in shade, almost look black. It has a dense, irregular pyramidal shape that, to some onlookers, after a some warm saki, might resemble a rearing dragon.

New growth in spring is light green, typical of the species, but quickly darkens up by midsummer. When its growth habit leaves openings to the trunk you'll see orange-ish brown exfoliating bark. It doesn't like strong winds (hot or cold) so it needs some protection but be sure to give it adequate air circulation to prevent prolonged wet needles which lead to fungal disease.

After 10 years of growth, a mature specimen will measure 6 feet (2 m) tall and 3 feet (1 m) wide, an annual growth rate of 6 to 8 inches (15 - 20 cm).

This cultivar originated as a seedling selecting in the mid-1980s by Iseli Nursery, Boring, Oregon, USA. Time has proven 'Black Dragon' to be one of the most popular dwarf conifers in the trade. At this link is Iseli nursery's description of this conifer with more pictures.

I purchased a Cryptomeria japonica 'Black Dragon' (dwarf Japanese cedar. I live in the coastal town of San Clemente, CA (zone 10). We are 1/2 mile from the beach. I am wondering if this will survive and what the root system is like? I want to plant in the ground but the location is near sprinklers and plumbing. Not sure if I should plant it in a large pot? Help.... thank you.

I have two in 9b in Sonoma County CA and they are doing very well, despite my dry summer air. They are native to Japan, which is humid in summer, so I am mindful of keeping them well-mulched and with reasonable irrigation. I doubt that their roots will disturb your plumbing. However, I think that it would work fine in a container, just don't pick one that is too small, make sure that your planting medium is well-draining (I use cactus soil when I plant conifers in containers) and you'll have to fertilize sporadically.

My black dragon is completely brown ?dead on one side the other side is green what do i do and why did this happen ( its 2-3 yrs old)

Hi Carolyn ... lots of things could have happened:
► sun scorch
► got too dry
► got too wet
► dog peed on it
► mechanical damage.

Bottom line, if the branches are dead, they won't come back. Trim them off and hope for the best.
