In the World of Iris, U.S. gardeners are highly partial to planting Siberian (Iris sibirica) and German (I. germanica) irises. Currently, in recent years there has been a sway to our native species called “flag irises”. Top of the list is Crested iris (I. cristata), a low-growing, rapidly spreading species that typically 3-6 inches tall. […]

Roof iris (Iris tectorum) is indigenous to China. This beardless iris is part of the crested iris group. Leaves stand 15 inches tall, fanned at the base and are ribbed. The clean green fan-like leaves remain mostly blemish-free most of the growing season. Plants give rise to purple-blue flowers with white and darker purple flecks starting […]

Most perennials demand well-drained soil. They perform poorly or die out when in ground that is constantly wet and soggy. However, a small number of perennials tolerate and even thrive in moist soils. Most plants listed here are all hardy within zones 5-8, and grow best in moist, humus-rich, well-drained soil. Most are okay getting their feet (roots and crown) wet for […]

Tall bearded (Iris x hybrida), Japanese iris (I. ensata), Siberian irises (I. sibirica) are very popular with U.S. gardeners and are favorites in my spring flower garden (USDA hardiness zones 3-9). The period from late August through mid-October is the ideal time to plant and/or divide irises. Don’t procrastinate…the earlier the better. Give plants enough […]

Siberian iris (called beadless iris) are favorites of gardeners and landscapers. Why? – ease of maintenance, plant longevity, and trouble free. Their flowers are smaller than the bearded iris blooms, but their grass-like foliage stays attractive all season long. They are more cold hardier. Siberian irises are mostly hybrids of two southwest Asian species, I. sibirica […]

Before purchasing and planting perennials, here are ten helpful tips to assist you in garden planning: Perennials die back to the ground in fall or winter and regrow from plant crowns or roots the following spring. Most perennials should be divided when they are dormant: Spring bloomers in the fall and Fall bloomers in the […]

Deadheading, the practice of removing the old spent flowers from perennials, is a way to improve a garden’s appearance and reduce overcrowding. Secondarily, many (not all) will rebloom after deadheading. Not all perennials respond to deadheading by reblooming. Most daylilies (Hemerocallis x.), coralbells (Heuchera spp.), and hostas (Hosta spp.) are prime examples of perennials that do not […]

Re-bloomers are specific cultivars that bring on a repeat floral show – two and sometimes three in one season. In my garden re-blooming iris and re-blooming daylilies return for another round of bloom in late summer and fall. Also, deadheading some perennials will cause them to flower again. You, the gardener, must supply needed […]

Irises (Iris spp.) are beloved spring flowering perennials. Perhaps some fans and clumps flowered poorly this spring. There are several reasons for this, including: old clumps in need of dividing, weather issues, poorly drained soil, inadequate nutrition, too much nitrogen fertilizer, heavy shade, and pest and disease problems. Irises do not compete well for space […]

Posted by Hugh on April 6th, 2012
Gardeners who desire more flowering from garden iris (Iris spp.) should be planting re-blooming types. Some cultivars may re-bloom up to three times in one growing season. The re-blooming trait is found both in bearded and beardless irises (I. germanica). Re-bloomers need to be well established for one year, sometimes two, to bloom multi-seasonly. Some […]
