Drosera intermedia is a small sundew with an unusually wide range of seasonal behaviour. A plant from a northern bog may spend winter as a tight resting bud, while a tropical accession can remain leafy in a suitable enclosure. Its spoon-shaped traps are attractive, but the most useful information on a collection label is often the origin written beneath the name.
Recognising the plant
The accepted species name is Drosera intermedia Hayne. Older literature may use D. americana. The Flora of North America describes young rosettes that can develop an obvious leafy stem, together with a flower stalk that curves outward near its base before rising. Flowers are usually white, sometimes tinged pink, and the reddish-brown seeds have a finely bumpy surface. Flora of North America.
The stem character in this regional flora distinguishes it from the other species covered there. It should not be expanded into the incorrect worldwide claim that no other sundew makes a stem: many tropical and Australian species do.
For identification photographs, include the attachment of the flower stalk and several complete leaves. The combination is more informative than a red rosette photographed from directly above. Colour alone cannot reliably distinguish this species from other small sundews.
A plant of very wet ground
Its distribution includes eastern North America, Europe and parts of the Caribbean and South America. The North American flora records plants in shallow standing water, wetland margins and peatlands; stems can lengthen in deeper water. Some plants produce vegetative plantlets in place of flower parts. These observations help explain why one individual may look like a compact rosette while another becomes taller.
North Carolina State Extension describes a plant suitable for moist, low-nutrient container culture, using rainwater or distilled water. It recommends strong light, with some shade tolerated, and lists seed, division and cuttings among propagation routes. This is practical regional guidance rather than proof that every geographical form has the same winter tolerance. NC State growing account.
In a collection, preserve reliable moisture while keeping the crown observable. A report of shallow water in the wild does not require burying every purchased plant underwater. Establish the accession under a stable regime first, then use its growth to assess any gradual adjustment.
Choosing the appropriate seasonal treatment
The ICPS distinguishes temperate accessions needing a winter rest from Cuban and South American material suitable for continued growth under protected conditions. Its account also notes differences among tropical plants, including a tendency for some Cuban material to flower heavily and decline. “Tropical intermedia” is therefore useful information, but not a complete life-history description. ICPS cultivation guide.
Before buying a plant for a permanent indoor display, obtain whatever provenance and seasonal history the grower actually knows. If neither is available, keep the uncertainty on the label and observe its cycle. Do not invent a locality from a similar photograph.
For temperate material, a sound resting bud should be recognised as a seasonal structure. For an actively growing tropical plant, sudden crown collapse needs investigation rather than an automatic dormancy diagnosis. The condition of the newest growth, changes in the growing environment and the accession's previous behaviour should guide the response.
Propagation and a documented cultivar
Seed creates new individuals; a successful vegetative cutting preserves the identity of its parent. Keep these routes separate in the propagation record, particularly when plants flower together and an unplanned cross is possible. Any plantlet forming on an inflorescence should be allowed to develop enough structure to handle before separation.
The cultivar Drosera intermedia ‘Éclat’ was published by Arnaud Schram in 2015 after a plant lacking the usual red coloration appeared in cultivation. His original account reports propagation through both seed and leaf cuttings. The name refers to the brightness of the mucilage. A temporarily green plant grown in weak light is not automatically that cultivar; the supplied identity and defining trait must be retained. Original cultivar publication.
For growers, the lasting appeal of D. intermedia is this combination of a recognisable small trap and a remarkably varied life cycle. Give the name, origin and seasonal observations equal attention, and its care becomes much easier to explain and repeat.
