Sieber's crocus

Sieber's crocus should be watered deeply yet infrequently for optimal growth. Water should not be allowed to accumulate in the soil; soak the soil until it is saturated and wait for the top soil to dry before watering again. On average, it is recommended that Sieber's crocus be watered every 1 to 2 weeks during spring and summer growing seasons, when temperatures are consistently above 40°F (4°C). Water less frequently in the fall and winter months, about once every 2 to 4 weeks.

Sieber's crocus (Crocus sieberi subsp. atticus 'Firefly') requires at least 6 hours of direct sunlight per day in order to bloom. It is best to place the plant in a south- or east-facing window or outdoor area that will receive plenty of sunlight throughout the day. Avoid positioning the plant in direct, unfiltered midday sun during the summer months as this could scorch the foliage. Sunlight requirements may depend on the environment and season- hours of direct sunlight may need to be reduced during especially hot or cold summer and winter months. Additionally, partial shade may be best for Sieber's Crocus in areas with very intense sun.

Sieber's crocus should be pruned once the blooms have faded. This species usually blooms in the late winter and early spring, so pruning should occur in late spring or early summer. Deadheading, or the removal of faded blooms, should be done by snipping off the flower heads close to the base. Do not use scissors or shears that may damage the foliage. Pruning can be done annually to promote health and vigor in the plant.
