Crocus chrysanthus aka Golden Crocus

Crocus chrysanthus is known as snow crocus or golden crocus. It belongs to the iris family, Iridaceae. Its native range runs from southeastern Europe to Türkiye. This includes Greece and Bulgaria. It is not native to Britain or Ireland. This small plant grows from a corm and forms tufts. It loses its leaves each year and rests underground.

Garden plants reach about 0.33–0.5 feet [0.10–0.15 metres] tall. Their spread falls within much the same range. RHS gives smaller sizes than Missouri Botanical Garden. Narrow, greyish leaves emerge with the flowers. The blooms stand upright and form small cups. Their colour ranges from deep yellow to yellow-orange. Some have maroon marks on the outside. The flowers have a light scent like honey. They bloom from February to March, spanning late winter and early spring. Snow crocus flowers around the same time as snowdrops. It blooms before the popular Dutch hybrid crocuses.

Grow this crocus in full sun or partial shade. It needs soil that drains well, with moderate moisture. Sandy or gritty soil suits it well. Heavy clay can lead to poor growth. RHS accepts acid, neutral and alkaline soils. Poor to moderately fertile soil is suitable. Plant corms in autumn, about 0.25–0.33 feet [0.08–0.10 metres] deep. Space them 0.25–0.5 feet [0.08–0.15 metres] apart. It is hardy in USDA zones 3–8 and RHS zone H6. Plants reach their full size in two to five years.

Use groups in lawns, rock gardens or beneath trees. It also suits sunny woodland, paths and shrub borders. Pots and gravel gardens offer other places to grow it. Plants spread through offsets and self-sown seed, forming broad patches. Leave lawn foliage uncut until it turns yellow. This takes about six weeks after flowering. Plants become dormant by late spring and need no pruning. Sow ripe seed in pots in a cold frame. Separate small corms while the plants are dormant.

Serious insect and disease problems are uncommon. Stored corms can rot, and birds may cause damage. Squirrels, mice and other rodents may dig up corms. Deer tend to leave the plants alone. Missouri Botanical Garden also reports tolerance of black walnut. RHS warns that people and pets must not eat the corms. Wear gloves and other protective gear when handling them.
