(Helunthetuum canadense or Crocanthe mum canadense), a North American plant of the rock-rose family (Cistaceae), native to dry rocky places and sandy soils from Maine to Ontario and Wisconsin southward to North Carolina and Missouri. It is a slender, sparsely branched, slightly woody peren nial, with small, narrow, nearly stalkless leaves and showy yellow flowers, 4, in. to 1 d in. across, usually borne singly or rarely two together, the petals soon falling. These are followed later by small short clusters of cleistogamous flowers, without petals, borne in the axils of the leaves. The plant is remarkable in that late in autumn crystals of ice sometimes shoot from the fissured bark at the base of the stem, whence the popular name. The hoary frost-weed (H. majus or C. tnajus), a similar species but of more western and southern range, exhibits the same peculiarity.
