Invasive Species: Lonicera fragrantissima, Sweet Breath of Spring
Sweet breath of spring is a multi-stemmed, upright, deciduous (evergreen in the South) invasive shrub. It grows from 6 to 10 ft (1.8 to 3 m) tall. The stems are hollow with stringy, tan bark and often are purple when young. Leaves are opposite, round, 1 to 3 in. (2.5 to 7.6 cm) long, and wide and usually persist into winter. Flowering occurs in the late winter, when the flowers develop in pairs in the leaf axils. The flowers are fragrant, tubular, 0.5 in. (1.5 cm) long, white to red or yellow, and thin-petaled. The abundant berries are 1/3 in. (8.5 mm) in diameter, ripen to orange or red in the mid-summer, and often persist throughout winter. Several species of exotic bush honeysuckles occur, and distinguishing species can be difficult. However, all have similar effects. Sweet breath of spring readily invades open woodlands, old fields, and other disturbed sites. Its rapid spread is attributed to dispersion of seeds by birds and mammals. It can form a dense understory thicket that can restrict native plant growth and tree seedling establishment. Sweet breath of spring is native to eastern Asia and was introduced in North America in the late 1800s. It has been planted widely as an ornamental shrub and for wildlife food and cover.
