Drosera nivea belongs to a closely compared group of small Western Australian sundews. Its name and familiar white flowers can suggest a simple colour distinction, but the botanical evidence is more nuanced.
Name and rank
Kew accepts D. nivea Lowrie & Carlquist as a south-western Australian species. It records the earlier combination D. citrina var. nivea as a synonym. Kew treatment
A plant with the varietal label should retain that name in its accession history. Updating the working name need not erase a traceable connection to older cultivation records.
Identification
The 2020 revision retains D. nivea separately from D. citrina. Orange pollen and a usually pale red ovary are useful characters; petal colour alone is unreliable. Taxonomic comparison
For a photographic record, focus on the flower centre and preserve a whole-plant image alongside it. A colour label without those details can make an uncertain identification appear more definite than it is.
Cultivation evidence and its limits
An experienced-grower discussion includes D. nivea among summer-sensitive pygmies. One contributor describes keeping such plants drained in summer and periodically moistening the lower substrate rather than leaving the whole pot saturated. The discussion also records differences between growers’ results. First-hand cultivation discussion
That is useful experience, not a measured species-wide optimum. The important practical distinction is between reducing moisture and allowing a small container to become dry throughout. Record what happened in the actual pot, including whether growth continued or a resting stage developed.
Keeping a reliable collection
Use the pygmy-sundew chapters for the wider growing and propagation framework. Keep separately sourced plants distinct, retain their original labels and document flowers before changing an identification.
A careful D. nivea record connects older names, diagnostic flower structures and observed cultivation outcomes. That is more useful than treating every white-flowered pygmy as the same plant.
