![]() This adaptation means Beardless rhizomes can be buried under a thick mulch to retain moisture without the concern of rot – a problem for Bearded varieties. The rhizome is smaller than that of Bearded varieties, and looks more like a large corm with long, fibrous roots below. These types typically enjoy areas with a high water table, such as beside bogs, creeks, and marshes. Beardlessīeardless varieties comprise a number of different species native to Asia, Europe, and North America. To improve drainage and heat retention, raised beds are often used for growing Arils and arilbreds. Popular arilbreds include cultivars like ‘Kalifa’s Joy’ and ‘Refiner’s Fire.’ Not as widely used in home gardens as the other two groups, arilbreds can be found at online bulb houses and plant specialty sites. Known as “arilbreds” they are suitable for growing in most regions and typically flower in May and June. However, cross breeding with Bearded varieties has produced many attractive hybrid cultivars. Highly fussy about their location, Arils demand excellent drainage, full sun, and thrive in hot locations.Īril species are difficult to grow in all but the driest and hottest regions. Miniature Dwarf Bearded (MDB) types are adorable early spring bloomers that flower in late March to early May and measure up to eight inches tall. Some reblooming cultivars flower first in spring with a second flush from late summer into early fall. The Bearded category has six groups based on shared characteristics such as size and flowering time. The shortest plants flower first, followed by intermediates, and the tallest are the last to bloom. ![]() ![]() They require humus-rich, well-draining soil in a full sun location and are typically hardy in Zones 3-9. These plants have thick, fleshy rhizomes that grow with the tops of these exposed to the sun and air. The beard is a small mat of soft, short hairs that may be the same color as the petals or contrasting – a little soul patch for attracting pollinators! The showy, full-petaled flowers have a sweet, floral fragrance and are marked by a beard at the base of the lower petals (falls). germanica, a species native to southern Europe and the Mediterranean. The highly popular Bearded category all derive from I. According to the American Iris Society (AIS), plants fall into three main groups: Bearded, Aril, and Beardless. ![]()
