Drosera paradoxa is familiar in cultivation as a sundew with rounded sticky blades on narrow petioles. Yet that familiar appearance covers a history of uncertain names and different accessions. Understanding the species requires distinguishing its original description from later horticultural use of “paradoxa” for similar plants.
The original species concept
Allen Lowrie described D. paradoxa in 1997 from northern Australia. His diagnostic key emphasised a perennial erect stem with a terminal rosette and especially narrow petioles, contrasting it with the clump-forming habit described for D. petiolaris. The published account allowed tall mature stems, while noting that young plants need not yet show that form. Original publication
A young rosette alone therefore cannot demonstrate either identity or misidentification. Keep the accession source, mature habit and flowers together in the record.
A Northern Territory field example
Boaz Ng’s 2026 account documents a Northern Territory form in sandstone creek and seepage habitats around the Arnhem Escarpment. It has elongated stems, narrow hairy petioles and a terminal crown of rounded blades. He describes plants persisting in habitats subject to wet-season flooding, while also observing many individuals completing their lives within one season. The relationship between regional forms remains qualified in his account. Northern Territory field observations
These observations illustrate why “perennial species” does not guarantee that every individual survives indefinitely. Equally, a plant dying after one season does not automatically establish that every accession must be grown as an annual.
Recent taxonomy changes the label problem
The description of D. actinioides recognises a distinct orange-flowered member of the broader paradoxa complex. That creates a reason to re-examine relevant old labels, but not to rename every orange-flowered or small-stemmed plant without checking the diagnostic treatment and provenance. Description of D. actinioides
Preserve informal locality names and “aff.” qualifications alongside any updated determination. They can retain distinctions that a single familiar species name has obscured.
Growing an identified accession
Carlton Carnivores’ account separates its “Type Form” from plants historically distributed under the name. It recommends strong light, warmth, a sandy peat or loose sphagnum-based medium, and moist to wet conditions while active. It reduces watering if a plant develops a resting state. Its listed propagation methods include seed, leaf pullings and crown division. Grower’s accession and cultivation account
These observations are a starting point for a documented plant, not evidence that every related taxon tolerates the same conditions. Record the temperature near the roots, how quickly water is used, and the rate at which new leaves replace old ones.
A stem acquiring an old leaf skirt is different from a softening crown. Assess the newest growth before stripping older material or making abrupt changes to water. If the plant has recently travelled or been repotted, include that history when interpreting a temporary slowdown.
What a useful propagation record contains
For a vegetative copy, retain the parent accession and method. For seed, retain both known parents and the date. If pollination was uncontrolled among related sundews, keep that uncertainty visible until the offspring can be assessed.
The value of this species in a collection increases when its label is supported by a sequence of images: juvenile rosette, mature stem, flower and fruiting stalk. Those images allow both its horticultural performance and its changing botanical interpretation to be examined over time.
