Description
English Ivy is a vigorous, evergreen climbing or ground-creeping woody vine. It climbs effortlessly up trees, walls, and fences using aerial rootlets, creating dense green carpets or blankets. It features two distinct growth phases: a juvenile climbing/creeping phase with lobed leaves, and a mature adult flowering phase with unlobed, ovate leaves and umbels of greenish flowers followed by dark berries.
Habitat
Thrives in temperate forests, woodlands, rocky slopes, coastal cliffs, and urban environments. Highly adaptable to shade, poor soil, and various moisture levels.
Native Range
Native to most of Europe and western Asia. Widely introduced, naturalized, and often considered invasive across North America, Australia, and New Zealand.
