The Privet family includes multiple species, cultivars, and hybrids of privets that
are often planted ornamentally but have a tendency to escape into natural habitats.
KISMA focuses mainly on the border privet (Ligustrum obtusifolium), amur privet (Ligustrum amurense), and hybrids of the two. Common identifying characteristics include:
woody shrub that grows around 10 feet tall with multiple stems
opposite leaves are usually oblong to ovate in shape, and around 1.5 inches long
stems, petioles, and leaves are often pubescent in varying amounts depending on the
white to cream flowers grow in clumps at the end of branches and bloom around June
Note: Differentiating between privet species can be challenging especially due to
the likelihood of hybridization.
Invasive privets are capable of escaping gardens and establishing thick understory
thickets in natural areas, making them a KISMA species of concern. An early infestation
of invasive privet on the Tech Trails was identified and removed by KISMA in 2021.
Although now removed, there are likely satellite populations elsewhere. Report any
instances of invasive privets found in natural habitats to KISMA, as we are currently
keeping an eye out for more occurrences of this species.
