"pleniflorus" 'Flore Pleno', had appeared by 1703, when it was illustrated in "The Duchess of Beaufort's Book". It spread (and was spread) rapidly through northern Europe (by vegetative means, as it sets no seed). With 3–5 outer segments and 12–21 inner segments, which are often misshapen, the flowers may be less attractive to the eye of the purist than single-flowered or neater double cultivars, but they are good value in the garden as the bulbs spread rapidly and the large flowers show up well.

Chlamydomonas nivalis become one of the most well-studied snow algae. Although its taxonomy is still being settled, the life cycle of this snow algae is now much better understood. The historical disputes about the classification and misclassification of specimens have resulted in a number of names from older publications that all mean to refer to "C. nivalis". These are: "Uredo nivalis", "Sphaerella nivalis", "Protococcus nivalis", and "Haematococcus nivalis". "C. nivalis" has been reported worldwide in mountainous regions, polar regions, or snowfields of every continent. It is the most abundant snow algae and typically composes the majority of cells identified in specimens taken
