Species of plant

Drosera peltata, commonly called the shield sundew or pale sundew, is a climbing or scrambling perennial tuberous species in the carnivorous plant genus Drosera. Among the tuberous sundews, D. peltata has the largest distribution, which includes eastern and western Australia, New Zealand, India, and most of Southeast Asia including the Philippines. The specific epithet is Latin for "shield shaped", a reference to the shape of the cauline leaves. Tuberous sundews are species of the genus Drosera that have evolved to live in summer drought conditions and aestivate as a dormant underground tuber. While many tuberous sundews are ground hugging rosettes, D. peltata is an upright species with a simple or branching inflorescence.

Drosera peltata is a perennial tuberous herb. Its underground tuber is generally found 4 – 6 cm under the soil surface, and its aerial parts range from 5 – 50 cm in height, with wide differentiation into several forms. The subspecies D. peltata subsp. auriculata is often the most robust, reaching up to 50 cm in height, whereas the form known informally as D. foliosa tends to be the shortest, often only 5–10 cm. Drosera peltata generally has an evident rosette of leaves at the soil surface, which is most pronounced in D. foliosa and in contrast often reduced to scales in mature plants of D. peltata subsp. auriculata. The aerial stem is simple or slightly branched in the nominal form of D. peltata, as well as in D. peltata subsp. auriculata, and the form informally known as D. gracilis. Subspecies auriculata is still considered a valid and separate species by some authorities. The major difference between the subspecies involve seed shape and sepal pubescence. D. peltata subsp. peltata has ovate (egg shaped) seeds and the sepals are hairy or pubescent, whereas D. peltata subsp. auriculata has linear seeds and glabrous sepals. Although demoted to synonyms of D. peltata by Marchant in 1982, the formerly recognised species Drosera foliosa and Drosera gracilis are again treated as separate species by the Tasmanian Herbarium and the Australian Plant Name Index. Drosera foliosa differs from the nominal form of D. peltata in having a well defined basal rosette of large, light green lunate leaves, and multi branched shorter stems. By contrast the nominal form of D. peltata has a less prominent basal rosette, and a single stem. It is mostly restricted to grasslands, herbfields and open woodland with grassy understorey. Drosera gracilis is similar to the nominal form of D. peltata but smaller and with distinctly red stems and leaves. In Tasmania it is restricted to wet peaty areas, and unlike the winter and spring growers D. peltata and D. foliosa, it grows in late spring and late into the summer.

Drosera peltata is one of the easiest tuberous Drosera to cultivate, a characteristic that is attributed to its forgiving nature when it comes to water and temperature. The tuberous Drosera typically require wet, cool winters, which is their active growing season, and warmer, nearly bone dry summers or the dormant tubers will rot. Drosera peltata can withstand wetter summers.
