Gladioli are commonly used in floral arrangements and are also popular in gardens for their dramatic appearance and vibrant, colourful blooms. Generally low maintenance, they are a great choice for busy gardeners.
Fun Facts
Symbolising strength, integrity and remembrance. They are also known as ‘sword lilies’, gaining their name from the sword-like leaves and have a rich history symbolising victory, being thrown into the arena to celebrate a Roman Gladiators win.
Traditionally, they are known as the 40th Wedding Anniversary flower and are the birth flower of August.
How to grow
They prefer well-drained soils in full sun, where they will thrive and provide the best blooms, often lasting for several weeks in summer.
Plant the corms 12-15cm deep and space them apart 10-20cm. Popular with pollinators, they help support local ecosystems and enhance biodiversity.
