Diascia spp., commonly known as Red Diascia, is a vibrant, free-flowering perennial that produces an abundance of rich red blooms from spring through autumn. The colourful flowers are held above neat, bright green foliage, creating a stunning display that brightens garden beds, borders, hanging baskets, and containers. Its compact, gently spreading habit makes it an excellent choice for adding long-lasting colour to both small and large garden spaces.
Renowned for its easy-care nature and extended flowering season, Red Diascia thrives in sunny to partly shaded positions and attracts bees and other beneficial pollinators. Its versatility and reliable performance make it perfect for cottage gardens, mixed perennial plantings, and decorative pots. Whether used as a border plant or cascading from containers, Red Diascia delivers continuous colour and charm with minimal maintenance.
