Ixia viridiflora is one of the most striking and unusual of winter rainfall bulbous plants. It is a winter-growing, summer-dormant, deciduous perennial.
It is one of the taller ixias, with upright, narrow, grass-like leaves, 400- 550 mm long. The inflorescence is a lax, many-flowered spike with 12 to 20 flowers per spike, on a slender stem, 500 - 950 mm long. Each flower is a brilliant turquoise-green with a conspicuous purple-black circular stain or 'eye' in the middle. The green color is not produced by green pigment but is due to the effects of light being refracted from striations in the cell wall and granules embedded in the pale blue cell sap. The green ixia is particularly showy, a number of flowers on the spike open together and persist for several days without fading or falling off. The flowers need sun and warmth to open, and are at their best on hot still days.
The basic requirements for growing this ixia are: sandy soil with good drainage, a sunny location, and a completely dry, dormant period in summer.
