Mushroom Japanese Cedar

Availability: Out of stock

So unique, the Mushroom Japanese Cedar (Cryptomeria japonica 'Mushroom') is a curious mounded, almost perfectly rounded evergreen that sweeps the ground! The bright green new growth darkens for the summer before transforming into gorgeous bronzy purple winter foliage! 

The airy soft foliage is a delight to have in the landscape! But it's that umbrella-shaped growing form that really takes the cake! Barely needing any maintenance to keep it in its tidy, formal mound, Mushroom is so easy to care for while delivering formal and whimsical garden décor without taking up much space or blocking views)!

Spring brings unique yellowish bottlebrush pollen at the ends of your branches which become unique little round cones in the fall for added interest! Japanese Cedars are heat and humidity tolerant throughout USDA growing zones 6 to 9 and only grow to a neat and tidy 3-4 feet in height and width. The arching, cascading growth rambles and spills over itself into a compact ball that sweeps the ground!

Planting and Application:

Mushroom Japanese Cedar is a gorgeous dwarf form with such whimsy to how it grows that we’re sure you'll want to make room for it in many locations around the garden! Seldom bothered by deer and tolerant of sun and part shade, there are few areas you can’t use a few of these curious plants! Even a large planter or patio pot will contain the genuine beauty of this dwarf evergreen tree! Mix and match with other Cryptomeria for a unique rounded and surreal garden border!

More shrub-like in appearance due to the smaller form and rounded canopy, use these accents and focal points around formal and informal garden beds and borders. This is a classic specimen in an Asian-inspired garden and Rock Garden! Or as evenly spaced accents along a path or walkway. Use in show-stopping groups in a mixed border or to highlight your foundation plantings with evergreen year-round appeal!

#ProPlantTips for Care:

Japanese Cedars thrive in full sun and partial shade so long as they are planted in well-drained soil with moderate moisture availability. The slower growth will never outgrow its environment or make you work for all this unique character! Can be pruned as needed to keep a more uniform shape, or could be allowed to grow more naturally and free-form. Should you need to do any pruning, wait until very early spring to nip out crossing/rubbing branches or clean up the interior for air circulation. Water well going into winter, this is especially important in the colder zones where the soil freezes. Protect from drying winter winds in the colder zones.

  • Full Sun & Partial Shade
  • Moderate, Consistent Moisture Needs
  • Any Rich Well-Drained Soil
  • Slow-Growing = Low Maintenance!
  • Prune If Needed In Late Winter/Early Spring
