Nursery contributed plant descriptions

Some Moraeas can be a challenge to grow – but not this one! In fact, this this plant almost couldn't be easier! Our trials have shown this species to be very drought tolerant, long blooming, vigorous, & it returns bigger & stronger every year! Large 3”, simple & elegant iris-like lavender flowers with yellow nectar guides appear atop 2' stems. Each bloom is ephemeral, but successive flowers appear over a long period – 6 to 8 weeks. When not in bloom, the grass like leaves are inconspicuous, & will disappear during drought. Ordinarily this species is only supposed to be Fall blooming, but for us it blooms twice – once in late Spring, & again in October. Widespread in both Summer & Winter rainfall areas of South Africa, so can thrive in both dry gardens & with irrigation. Rich soil would be good, but it's not required.
