It ’s extremely common in USDA Hardiness Zones 4 to 9 because it ’s rattling – if you opt to grow one of your own , you wo n’t be disappointed .
Cultivation and History
‘ Spartan ’ is a cultivar of Taiwanese juniper ( Juniperus chinensis ) , a species that hail from parts of north and east Asia . If you ’re queer about this broader group of plant life , you might be interested in ourcomprehensive usher to the specie .
In 1950 , ‘ Spartan ’ was a seedling selected by Monrovia Nursery , Co. , a caller base in California . Monrovia sent a few film editing from the seedling to Thomsen ’s Nursery in Denmark and they dub the plant ‘ Helle , ’ a distaff variant of the name Helge .
Monrovia officially named the plant ‘ ascetical ’ in 1961 and today it ’s one of the most democratic junipers on the food market .
It ’s a low - maintenance , drouth - liberal tree diagram that extend to about 15 feet grandiloquent within about 10 year and has a spread of about five feet . And it grows fairly chop-chop – especially for a juniper . Juvenile ‘ austere ’ plants can get over an in a calendar month .
The trees by nature have a columnar , pyramidic material body with a wider base and a tapered top . The plant also produces attractive blue berries , which are in reality small cone .
Propagation
It ’s technically possible to circularise your own from seed , but it ’s difficult , takes year , and has a modest achiever pace . Stick with the easier methods for home finish .
From Air Layering
I know this method and find it to be exceedingly reliable . This involve cutting off a strip of bark from a branch and tamp down moss around it , allowing raw root to develop while it ’s still sequester to the parent plant .
Read more about air layer in ourgeneral guide to juniper care .
From Cuttings
In the early fountain , slap on those glovesand grab a clean pair of pruner . It ’s clip to take carving if you have access to a fledged works .
Before you lead out , mix in one part sand with two parts potting soil and fulfill a six - inch pot with dear drain . Make a mess in the marrow of the soil using a pencil or your digit .
Look for goodish hardwood that is at least a quartern - column inch in diam and cut a ft - long length . Snip the bottom of the cutting off at a 45 - degree angle and dispatch any farewell from the bottom half or so .
Dip the cut of meat conclusion in rooting hormone and stick the cutting into the mess you made in the potting grunge . Firm the soil up around it and give the soil a squeamish drink of water . You need it to be moist but not soggy .
Place the pot in an area with bright , indirect lightness and keep the soil moist . Within about two calendar month , roots should form . There ’s no motivation to labor into the soil to be certain , just give the plant a little tug . It should resist .
Once you see new maturation beginning , it ’s ready for transplantation . Keep the plant indoors until the last predicted icing date in your domain . A few week before the last frost date , start hardening off your cutting .
Take it outside for a visit to a protected spotlight with some Lord’s Day and leave it there for half an hour . Bring it back at heart . The next day add another 30 minute , then another 30 minutes on the third daytime . Keep doing this until you could leave the plant outside all day .
Just remember to bring it in if there is any profound wind , Baron Snow of Leicester , immobilise atmospheric condition , or other coarse condition . you may return to hardening off when the weather meliorate .

Once it ’s in the primer coat in a berth with full Dominicus , keep an eye on the soil moisture level for the first few geezerhood . Once it ’s established , you’re able to be a flake lazier about watering .
Chinese junipers be given to need more moisture than other species of junipers , but ‘ Spartan ’ is notably drouth - broad .
For the first year or two , piddle when the top half inch to inch of ground has dried out . After that , add H2O only when the top two in of soil feel dry .
An inch or so of well - rot compost applied at the base as a mulch will never go unwelcome . Mulch prevents green goddess from popping up and it help the soil retain water .
