  • water dropWater

    Winter aconite should be watered moderately without letting the soil become waterlogged. During the growing season, ensure the soil is consistently moist by watering once or twice a week. Approximately 1 inch of water each week is ideal as these plants do not tolerate drought well. Reduce watering once the foliage begins to yellow and die back after flowering, as the plant goes dormant during the summer.

  • sunLight

    Winter aconite thrives best in partial shade to full sun. An ideal spot for this plant is under deciduous trees, where it can receive sunlight in the winter and spring before the trees leaf out and provide shade during the summer months. Avoid placing winter aconite in deeply shaded areas as this could affect its blooming.

  • thermometerTemperature

    Winter aconite can survive winter temperatures down to -20°F as it is cold-hardy. They prefer the cooler end of the temperature spectrum and do well in spring temperatures ranging between 35°F and 65°F. To flourish, this plant's ideal temperature conditions are cool to moderate, as prolonged heat and humidity can lead to dormancy or decline.

  • scissorsPruning

    Winter aconite does not require regular pruning, but spent flowers can be deadheaded to maintain appearance. Pruning is typically not needed; however, after flowering, foliage should be allowed to die back naturally to provide the bulbs with energy for the next season. The best time for any cleaning around the plant would be after the foliage has yellowed and wilted.

  • circleLife cycle

    Eranthis hyemalis 'Schwefelglanz', commonly known as winter aconite, begins its life cycle with seed germination, typically occurring in late spring or early summer. The seeds develop into small corms, which lie dormant underground during the summer. In autumn, the corms produce roots and shoot tips in preparation for the cold months. Winter aconite enters its most visible stage in late winter or early spring when it produces a rosette of leaves and bright yellow flowers that can push through the snow. Following pollination, the flowers develop into fruiting bodies containing seeds, which are then dispersed to give rise to the next generation of plants. As the temperatures rise in late spring, the above-ground parts of the plant die back, and the corms enter a period of dormancy until the next autumn.

    • Propogation time

      Early spring

    • Eranthis hyemalis 'Schwefelglanz', commonly known as winter aconite, is typically propagated by dividing its tubers. The best time to carry out this propagation method is after the plant has finished flowering and the foliage has died back, which is usually in late spring to early summer. To propagate by division, carefully dig up the clump of tubers and gently separate them, ensuring that each section has at least one growth point. Replant the divisions promptly at the same depth they were originally growing, which is typically about 2 to 3 inches (5 to 7.5 centimeters) deep, and water them well. This division allows the plant to rejuvenate and also increases the number of plants in your garden. It is the most popular method because it is simple and effective for increasing your stock of winter aconite.
