Irises--the rainbow flower

'Each spring, as the tightly rolled buds on the irises in Billie Adams's garden begin to unfurl, a smile spreads across her face. ... she's remembering her dear friend Mary Shields, who offered her a few clumps of these hardy perennials more than 25 years ago...'

A beautifully illustrated introduction stressing irises for mild climates (the book was originally published in New Zealand), with descriptions of important species, information on soil & cultivation requirements, discussions of propagation, pests, & diseases, & suggestions for using irises in the landscape.
     

Take a close look at an iris and you will see three sets of three petal-like parts. The lower set, called the falls, flares out and hangs down. The upper parts, known as standards, curve up into a dome. The three upright petals and three drooping sepals of an iris are symbols for faith, valor, and wisdom.

Bearded iris are those with the thick falls. Beardless irises, originally native to Asia, often bloom after many of the bearded. Aril irises, often grown in warmer climates, have been hybridized with bearded irises to produce taller plants with large blooms.
