Galanthus nivalis York State, Michigan, Utah, New Jersey, Ohio, Pennsylvania, Maryland, Virginia and North Carolina). Although often thought of as a British native wild flower, or to have been brought to the British Isles by the Romans, it is now thought that it was probably introduced much later, perhaps around the early sixteenth century. "Galanthus nivalis" grows to around 7–15 cm tall, flowering between January and April in the northern temperate zone (January–May in the wild). They are perennial, herbaceous plants which grow from bulbs. Each bulb generally produces two linear, or very narrowly lanceolate, greyish-green leaves and an erect, leafless scape
Chlamydomonas nivalis temperatures rise above 30 °C. It is a true snow alga because it performs better in low temperatures than warm temperatures. Due to "C. nivalis"’ ability to perform photosynthesis well from cold to moderate temperatures, this species is considered a cryotolerant mesophile rather than a cryophile. This organism is also very resilient as they can also survive in warm soil for weeks. They can also tolerate dryness and room temperature for as long as 6 months. Fungi, worms, bacteria, and viruses have been found to associate with or live in the same environment as "C. nivalis". Encapsulated rod-shaped gram-negative bacteria
