Cup crocus Fuscotinctus is characterized by its brilliant yellow flowers that sometimes have dark streaks or spots on the outside of the petals. The flowers are bowl-shaped and open wide on sunny days, while they remain more closed in cloudy or chilly weather. The plant grows to about 8-10 cm tall and has narrow, grass-like leaves with a silvery midline, creating a nice contrast to the bright yellow flowers.
Cup crocus Fuscotinctus is one of the first flowers to appear in spring, often as early as February or March depending on the climate. Its early flowering time makes it an important source of pollen for bees and other early pollinators.
