Growing Notes

As an Iris pumila cultivar, 'Boo' carries the genes of one of the most cold-hardy and adaptable iris species. Native to the steppes of Eastern Europe and Central Asia, I. pumila thrives in harsh conditions—extreme cold, heat, and drought. This makes 'Boo' an exceptionally tough garden plant, ideal for challenging sites where other perennials struggle. The standard dwarf bearded class (8-16 inches) bridges the gap between miniature dwarfs and intermediates, offering a longer bloom season when planted with both. Plant in full sun with sharp drainage. The species' natural tolerance for alkaline soils makes it a good choice for difficult sites.
