About Natal lily
Gladiolus dalenii, commonly known as Cornflag, is a perennial cormous plant from the Iridaceae family, valued for its striking spikes of funnel-shaped flowers. Its blooms, ranging in colors from orange and red to yellow and cream, open sequentially along the stem, creating a vibrant display. It is ideal for flower beds, borders, and as a cut flower, adding an exotic and vertical touch to the garden.
Native range
Sub-Saharan Africa, from Ethiopia and Sudan to South Africa
Care tips
It prefers full sun for optimal flowering, although it tolerates some partial shade in very hot climates. Watering should be regular during the growing and flowering season, keeping the substrate moist but not waterlogged. It requires well-drained soil rich in organic matter. A common mistake is planting the corms too late in the season, which can result in poor or no flowering.
How to save a dying Natal lily
- Warning signs
- Yellowing or browning leaves, general wilting, sparse or no flowering. Indicates water or nutritional stress.
- First aid
- Check watering (moist but not waterlogged soil), provide balanced fertilizer if not done, ensure full sun.
- What kills it
- Overwatering rotting the corm, complete lack of sun, or poor, undrained soil. They are susceptible to root asphyxia.
