Whitetop - Cardaria spp.
Family: Brassicaceae

THIS PAGE IS UNDER CONSTRUCTION.

Description

Cardaria spp. are erect perennial herbs, usually pubescent, which spread by horizontal rootstocks. Basal leaves are petiolate, lyrate when young. Upper leaves are sessile, elliptical to lanceolate, with auriculate or sagittate bases which clasp the stem. The flowers are perfect and produced in numerous dense racemes. The petals are white to cream colored and clawed. The 3 Cardaria species are distinguished by their texture and the shape of their fruits.

Species Surface Shape of fruit

C. pubescens pubescent inflated, subreniform to obovate

C. draba glabrous compressed, cordate

C. chalepensis glabrous compressed, subreniform to obovate

Interesting facts

Cardaria spp. are aggressive perennials that can reproduce by seeds or rhizomes. They are common in fields, pastures, roadsides, and waste areas.

The aggressive nature of the plants allows them to outcompete and displace native species.
