Tall, straight and formal
Red gladioli are a favourite in big arrangements. The spike is tall and straight, with flowers opening from the bottom upwards, so you get a natural gradient of fully open flowers, half-open ones and tightly closed buds at the tip. That is why one stem is enough for a narrow vase, and three to five make a dramatic, formal display.
Styling red
Red gladioli suit green foliage, white flowers or a plain jar placed on a hall table. They also hold their own with hot-coloured native plants such as kangaroo paw, which have a similar upright form. Avoid pairing with too many other reds, since the stems are already imposing.
What a red gladiolus traditionally says
Red is linked with passion and energy, and the gladiolus with strength and sincerity. Together they make a flower that says respect or devotion rather than a soft romantic note. Many people searching for "red gladiolus" are looking for a gift or a garden plant, and both work.
In your own garden
Red varieties are no harder to grow than other colours, but they do like a sunny, sheltered position.
- Set corms in spring, 10 to 15 cm deep and about 15 cm apart.
- Stake in windy sites, and tie the spike loosely.
- Water in dry spells, because dry soil causes short spikes.
- Check regularly for thrips, a common pest in Australian gardens.
In humid Brisbane, plant in autumn to avoid summer heat and storm damage. In Melbourne, plant from September to December for flowers over summer.
Poison note for pet owners
The ASPCA classes gladiolus as poisonous to dogs, cats and horses. Drooling, vomiting and diarrhoea are among the signs. Call a vet if you are worried.
