D. moroides is a straggly perennial shrub, usually flowering and fruiting when less than 3 m (10 ft) tall, but it may reach up to 10 m (33 ft) in height. It is superficially similar to Dendrocnide cordifolia, with the most obvious difference being the point of attachment of the petiole to the leaf blade—where D. moroides is peltate, i.e. the stalk attaches to the underside of the leaf and ...

Individual trees can live for over 300 years. [ 4 ] The leaves are thick with a waxy texture, elliptical, 7 to 15 cm ( 2 + 3 ⁄ 4 to 6 in) long and 4 to 8 cm ( 1 + 1 ⁄ 2 to 3 + 1 ⁄ 4 in) broad, arranged spirally; they are glossy dark green above and a lighter, more grayish green beneath, with an entire margin.
In good conditions, bald cypress grows fairly fast when young, then more slowly with age. Trees have been measured to reach 3 m in five years, 21 m in 41 years, and 36 m in height in 96 years; height growth has largely ceased by the time the trees are 200 years old. Some individuals can live over 1,000 years.
However, when these commercial varieties turn green, even they can approach solanine concentrations of 1000 mg/kg (1000 ppmw). The U.S. National Toxicology Program suggests that the average American consume no more than 12.5 mg/day of solanine from potatoes (the toxic dose is several times this, depending on body weight).

Imidacloprid also exhibits excellent translaminar movement in plants and can penetrate the leaf cuticle and move readily into leaf tissue. [ 29 ] Since imidacloprid is effective at very low levels (nanogram and picogram), it can be applied at much lower concentrations (e.g., 0.05–0.125 lb/acre or 55–140 g/ha) than other insecticides.
