As a houseplant, Autumn Crocus requires regular watering and does best in long-lasting, direct light less than 1 foot from a window. The plant prefers well-draining soil and typically does not require added fertilizers if repotted each time it doubles in size. Overall, Autumn Crocus is a rare and beautiful addition to any garden or indoor space.

Water

Soil
