While junipers can be a nice feature in the landscape, many that would be commonly used up north just do not do well in our Southwest Florida climate in regard to pest and environment pressures. The native juniper, the red cedar is a great adaptable landscape tree, but it does not have many forms other than large, upright growth. Groundcover type junipers are a little touchy about the heat and humidity and sometimes decline over time. I have been watching a groundcover-type juniper used at our Centennial Park facility that has done pretty well since it was installed in 2019. This juniper, the Parson’s Juniper, or Juniperus davurica expansa ‘Parsonii’, is flourishing and looking very ornamentally useful especially around the perimeter of the building.
Parson’s juniper is low, spreading juniper with blue/gray-green needled foliage. Growing generally no more than two-foot tall, it can spread over four-foot wide – even up to eight feet over time! As such, the benefit of this shrub as a groundcover is in full display when given enough room between plants – five feet on center will allow sufficient room for them to become mature and grow together. Parson’s, like many junipers, is a bit prickly to the touch, so wear gloves when handling. Growing best in full sun, it can tolerate some shade in well-drained soil. Once established, Parson’s will not need much supplemental watering and will benefit from not having irrigation that wets the foliage from overhead sprinklers.
Parson’s juniper also does well in slightly sloped areas and looks particularly nice with landscape plant s such as podocarpus, dwarf schefflera, or silver buttonwood as a backdrop. Mulch with two to three inches of your favorite organic mulch keeping it away from the trunks – this will help suppress weeds and retain moisture. Although Parson’s may be considered a “groundcover” it does not mean that you should walk on it – it is not tolerant of foot traffic. I have seen Parson’s planted in parking lot islands where people have walked over them so many times that branches broke and the individual junipers were damaged and in decline.
Certainly cold-tolerant in regard to winter freezes, Parson’s does not like overly wet soils or low areas prone to flooding – root rots can develop when soils are not well-drained. Overhead irrigation can also promote wet foliage which is the perfect environment for fungal infections and blights. Mites can also be a problem during the dry season with telltale webbing and browning needles. One of the most serious insect pests can be bagworms. Loss of foliage and large dangling bags made of silk and twigs encasing the hungry caterpillars will indicate an infestation.
Bottom-line, Parson’s juniper seems to be one of the better low-growing juniper selections for our area. Their evergreen nature, great texture, and sustainable constitution make them a great choice for any landscape.
