Rain Flowers, with their crocus-like blooms, bring a soft, enchanting beauty to your garden. Native to marshlands and riverbanks of South America, these bulb-grown perennials thrive in warm climates. Ideal for rock gardens, patio containers, or narrow borders along walkways, they add a pop of color wherever space is limited. In colder regions, bulbs can be lifted and stored after the first frost, ready to replant in spring.
