info
Water this plant regularly, when the top inch or so of soil feels dry. If you establish this pattern over several years, then you can cut back to watering every week or two (or less) in dry weather. Use drippers, emitters, or a slow stream of water so that it doesn’t run off; allow the water to trickle all the way down through the deepest layers of soil. In a pot slowly water the entire surface until water comes out of the bottom of your pot.

Plants grown in cool coastal climates and in shade will require less water.

Growing Notes

Superior to the ubiquitous gas-station plant, this dietes is a reliable, clean-looking “iris” with a full, somewhat grassy look, and showy flowers. Perfect mixed with finer grasslike plants or among succulents, as well as in pots.
Use as a grass-like element that happens to flower, rather than as a flower feature.
Pull dead leaves from the base. Do not crop.
Remarkable tolerance of shade or sun. Plants in sun will bloom more.
