Larger plants to right are D. x fontinalis; to left are D. tomentosa.
Range: Chapada Diamantina, Chapada do Veadeiros, and Serra do Cabral Mountains of Bahia, Goias, and Minas Gerais, Brazil
An unusually common hybrid sundew from the south-central plateau of Brazil, this plant is the offspring of D. (grantsaui x tomentosa), and is common in very wet seepage areas (it is named after its habit of growing near permanent flowing springs), often in sphagnum or sandy peat soils. It grows to around 4 cm across, developing on a short stem often only a few mm long and in a semi-erect fashion with lanceolate leaves bearing elongate roughly parallel petioles and the lamina being typically narrowly spatulate to elongate ovular and equal to or up to twice the length of the petiole. Color can be green to bright scarlet, or even wine red, with red tentacles. Inflorescences are often longer than either parent species, up to 36 cm in length, and bear sparse glands along their length. Flowers may be up to 1.5 cm across, with wedge-shaped or ovular petals colored in shades of light pink to lilac lavender. The hybrid is readily distinguished from its parent species (especially the typically more similar D. tomentosa) by the size of the inflorescence, distinct narrower petiole with obovate lamina, and short stem-forming habit.
Cultivation: grow in a soil of either aerated sphagnum or 1:1 peat/sand, kept very moist and humid and preferably with aerated flowing water in the root system, with temps of 65-85°F day, 50-60°F, year round. Sow seeds on soil surface, and grow in strong artificial light to full sun.
Lifespan and reproduction: perennial. Reproductively sterile, but may propagate naturally via division or root budding and can be grown through cuttings.
