Always check the top few inches of soil for dryness before watering to avoid overwatering. During the winter dormancy period, reduce watering significantly to prevent root rot, only providing water to keep the soil from completely drying out.

  • circleLife cycle

    Crocosmia 'Severn Sunrise' begins its life cycle when its corms (underground storage organs) are planted in late winter to early spring. After planting, corms sprout and produce long, slender leaves, followed by stems that bear a succession of tubular to funnel-shaped flowers showcasing a blend of orange, pink, and yellow hues throughout summer. As the flowering season ends, the plant enters a period of dormancy in late autumn to winter, during which the foliage dies back. During this dormant period, the corms rest and survive below the frost line. In spring, new growth emerges from the corms, often with additional cormlets which can be divided to propagate new plants. Finally, the life cycle repeats annually as established plants continue to grow, bloom, and enter dormancy in a perennial rhythm.

      Late spring to early summer

    • The Crocosmia 'Severn Sunrise', often known as falling stars or coppertips, is generally propagated by dividing the corms, the small bulb-like structures that reside underground. This process is done in the spring just before new growth begins. To propagate, gardeners dig up the clumps of corms and gently separate them, making sure that each new section has at least one growing point or shoot. These divided corms can then be replanted immediately at a depth of approximately 3 to 5 inches (about 7.5 to 12.5 cm), spaced about 6 to 8 inches (15 to 20 cm) apart to allow sufficient room for growth. With proper care and favorable conditions, these new plantings will develop into flowering plants that will enhance gardens with their vibrant orange and red hues.
