Japanese cedar is a particularly lovely, variable, and neglected conifer that gives a lot enchantment within the panorama. Not an precise cedar in any respect, Japanese cedar is within the genus Cryptomeria, which is within the household Taxodiaceae—the identical household that features bald cypress (Taxodium spp. and cvs., Zones 5–11). Cryptomeria japonica can attain 50 to 60 ft tall in cultivation and 80 ft tall within the wild. It may be saved extra compact with cautious pruning, however correct cultivar choice can eradicate the necessity to prune totally. Japanese cedars are drought tolerant as soon as established, they usually additionally tolerate the humidity of southeastern gardens. Over 100 cultivars of Japanese cedar can be found in america, together with 12-inch dwarf kinds.
‘Globosa Nana’ has lengthy been my favourite cultivar. Because the title suggests, it kinds a pure globular, billowy form with out pruning. Its delicate needles make you wish to pet it, and it jiggles once you hug it! The spirally organized needles are shiny inexperienced in summer season and deepen to darkish inexperienced in winter. In colder, extra uncovered websites, foliage might develop enticing tones of bronze and even gold. Some cultivars of Japanese cedars produce an overabundance of male cones that may take away from a plant’s total look, however ‘Globosa Nana’ shouldn’t be a type of. It requires little care and grows properly with common moisture in good, well-drained backyard soil in full solar to dappled shade.
In 10 years, ‘Globosa Nana’ can attain 4 ft tall and broad. A 30-year-old specimen on the Nationwide Arboretum in Washington, D.C., is 8 ft tall and broad. It makes a superb substitute for boxwoods (Buxus spp. and cvs., Zones 5–9), dwarf yaupon hollies (Ilex vomitoria cvs., Zones 7–11), Japanese hollies (I. crenata and cvs., Zones 5–7), and different frequent basis crops. If the necessity arises to prune ‘Globosa Nana’, I like to take action in November and December, after I could make use of its delicate foliage in vacation decorations. It really works properly in tabletop preparations and makes glorious vacation wreaths. I’ve 20 rising at my farm only for use as lower greenery.
In the event you’re in search of dwarf Japanese cedars which might be even smaller, think about Dragon Warrior™ (C. japonica ‘sPg-3-005’), which reaches 3 to 4 ft tall and a pair of to three ft broad in 10 years, and Dragon Prince™ (C. japonica ‘sPg-3-014’), which will get 2 to three ft tall and three to 4 ft broad in 10 years. With its blue-green foliage, Chapel View™ (C. japonica ‘PIICJ-I’) can also be a notable choice; it reaches 7 to eight ft tall and 5 to six ft broad in 10 years.
