Wild Iris 140MM

Dietes grandiflora

I am Wild Iris. My family originated from South Africa.

Habit Strappy - Ideal for mass planting
Plant family Iridaceae
I am a hardy strappy perennial producing white, iris-like flowers with lilac centres and yellow and brown highlights on long stems are throughout spring and summer. I will thrive in almost all soils including damp and boggy conditions. Hardy I cope with extremes of temperature and dry conditions. I am a good choice for locations where many other plants may struggle such as public spaces like car parks and along road sides. I am one tough customer outcompeting many weeds. I require almost no maintenance to keep me looking at my best.
I am popular and will make you happy because...
My strappy foliage and long flowering white and lilac blooms adds structure and colour to the garden
Hardy I am ideal for windy areas, exposed locations and coastal planting
I am suitable for containers, borders, mass planting and low maintenance gardens

Height: 1m Width: 1m(Size at point of sale approx. 40cm including pot)
Water needs: Low (once established)I need minimal water once established

Frost tolerance: High
