Tall, Skinny Conifers for the Southeast

Narrow forms of familiar favorites make the perfect accent or a stylish screen

Perhaps you struggle with when it ’s appropriate to use an exclaiming percentage point at the end of a sentence . However , you do n’t require to struggle with when to use one in the garden ! If you need a plant for a tall , narrow-minded outer space in your landscape painting , or if you involve just the right emphasis , often there is a coniferous tree that can fulfill the void . In the Southeast , we need to be heedful with conifer choice if we want a sure affair . Below are some of the good of the good conifer for narrow , upright forms .

Two striking columnar arborvitaes: One old, one new

One of the first truly minute pick of arborvitaes to come to market place was ‘ DeGroot ’s Spire ’ ( Thuja occidentalis‘DeGroot ’s Spire ’ , Zones 2–7 ) thanks to plantsman Constant DeGroot of Sheridan Nurseries . It was selected in 1970 . Its medium unripened foliage is somewhat twisted and turns a saturnine mossy green during the winter . It will reach 15 to 20 foundation magniloquent and only 3 to 4 feet wide in 15 to 20 long time .

display an middle - popping yellow during fountain and summertime , ‘ Jantar ’ arborvitae ( T. occidentalis‘Jantar ’ , Zones 3–7 ) was originally found in Poland as a sport on Emerald Green arborvitae ( T. occidentalis‘Smaragd ’ , Zones 4–8 ) and introduced into the United States in 2012 . As insensate conditions approaches , it takes on a fond amber and golden tone . In fact , its name is Polish for amber . Sometimes you will also see this plant sold under the name ‘ Amber Gold ’ . The xanthous colour of ‘ Jantar ’ is best in full sun . gestate it to strive 6 to 10 substructure tall and 2 to 3 feet panoptic in 10 years . With a striking good habit , this selection will summate drama to the landscape painting .

Yew and Japanese plum yew fill the same niche in different zones

‘ Viridis ’ yew ( Taxus×media‘Viridis ’ , Zones 4–7 ) is a slow - growing narrow hybrid between English yew ( T. baccata , Zones 5–8 ) and Japanese yew ( T. cuspidata , zona 4–7 ) . good suit for cooler regions of the Southeast , ‘ Viridis ’ is best sited in partial shade , although it can handle more Dominicus with passable moisture . Ultimate size will be partially dictated by site condition ; however , you may expect fledged dimensions of 15 human foot tall and 4 feet wide of the mark over a very tenacious time . Yews in general take to sheering very well . But nearly every part of this plant is toxic if consumed .

If you live in a hardiness geographical zone where it ’s a trivial too hot for most yew to grow , why not try just Nipponese plum yew ( Cephalotaxus harringtonia‘Fastigiata ’ , Zones 6–9 ) ? The genusCephalotaxusis named for its resemblance to yew . The straight mintage of this plant can get quite large . However , ‘ Fastigiata ’ , which is admittedly rotund for a narrow cultivar , grows 10 feet tall and 5 substructure extensive over many age . The outgrowth are strong , with needles spirally set around the stems . This works is traditionally grown in the subtlety but can handle sunlight if established with adequate wet .

Roadside toughness with a formal appearance

There are many unique and narrow descriptor of Eastern red cedar ( Juniperus virginiana , Zones 2–9 ) . However , for overall temper , tolerance to a variety of conditions , and lack of petulance , ‘ Taylor ’ Eastern red cedar ( J. virginiana‘Taylor ’ , Zones 3–9 ) is one of the honorable . ‘ Taylor ’ is nominate after the small town of Taylor , Nebraska . Allen Wilke , a gardener from Columbus , Nebraska , found the plant in 1978 . The parent plant was 25 metrical unit marvelous and 3 feet panoptic . It was from this tree diagram that Wilke take his original cuttings . you’re able to expect a similar size of it in your garden . plant thrive in full sun and are tolerant of almost any soil ( except for soggy soils ) .

Finding the right fit

Be cautious about institute in overly amended , rich soil and using heavy fertilizer for any plant you desire to have a narrow-minded class . This can cause a works you expect to be slender to grow too fast , and its narrowness can not be insure . Also , when purchasing a flora , look for a specimen with one unattackable central leader , or remove any offshoot competing with its central loss leader . to boot , pay attention to the expected mature size of minute industrial plant . Before planting , make certain you have enough space for that plant to reach full maturity . Unless you are planning a yearly pruning regimen or expecting the works to be impermanent , this is very crucial .

Not all minute conifers have to be place on the corner of building . Many look their in force out in the open , where their tall , narrow forms can be appreciated . Groups of three can be particularly striking where plant are given enough space to be close without touching . If you decide to use these conifers in your garden , have fun , experiment , and enjoy .
