Do Iris reticulata come back each year?
If you hope for them to come back year-after-year they should be planted in well-drained soil that dries out in summer. This is because the original Iris reticulata hail from Turkey, Iran, Iraq and the Caucasus, where they might typically be found flowering along the snowline on a remote mountainside. Mid-summer, from mid-July to early-September, is the best time to divide and move iris, after plants have bloomed. This ensures adequate root growth and establishment before winter. So if your iris bed has become too thick or is producing fewer flowers, then plan to divide and conquer!Iris will grow in deep shade, but probably not flower. Provide your irises with good drainage. A raised bed or planting on a slope are ideal places to plant iris.Ensure these plants receive a minimum of 6 hours of sunlight daily; check annually for any changes in their sun exposure. Irises need at least 6 hours of sun per day if they are to flower to their fullest potential, and you should evaluate their location every year to ensure this demand is met.As with most Spring Bulbs, Reticulata Irises do great in pots. Make sure your pot is at least 20cm deep, and has good drainage holes. Select a good quality potting mix, and add a little compost in.Some species of iris are valuable high water problem solvers. These are actually semiaquatic, and although they can live in dry soil, they thrive in saturated, poorly drained conditions. Most will grow far larger in wet ground than in drier soil.
Is Iris reticulata a perennial?
Iris reticulata, commonly called reticulated iris, is a bulbous perennial iris that is native to Turkey, the Caucasus, Northern Iraq and Iran. It is a low-growing purple-flowered reticulate or netted iris that blooms in March to early April in the St. Irises – Perfect For Fall Planting! With looks to rival the beauty of the rainbow-riding Greek messenger of the gods it’s named after, and a spectrum of colors to dwarf the rainbow itself, the iris flower is a quintessential ornamental and an obvious garden favorite. Irises are very reliable, hardy and easy to grow.Irises require at least a half-day (6-8 hours) of direct sunlight. Some afternoon shade is beneficial in extremely hot climates, but in general irises do best in full sun.

Their late spring and early summer blooms are elegant and regal, their sweet fragrance is reminiscent of grape soda or root beer, and their ability to multiply rapidly has made them the ultimate “pass-along” plant.Dividing irises helps to rejuvenate the plants and increases the floriferousness (amount of flowers) for the following year. These fast multiplying rhizomes—the bulb portion of the iris is called a rhizome— create large clumps in your flower bed in just a few years.
What to do with iris reticulata after flowering?
Leave the bulbs planted in the ground throughout the year. After flowering, allow the leaves and stem to fully die back or turn yellow before removing it, as this is feeding the bulb for next year. As the leaves are very fine, they may not need removing at all unless they look untidy. Bloom season is over – now what? Remove spent bloom stalks by cutting them off close to the base. This can be done as soon as all blooms on the stalks have withered. Healthy green leaves can be left alone but remove any diseased or browned outer leaves.
What is the best month to plant iris?
Late July through mid August is the best time to plant, move or divide iris. Iris is one of the most popular perennials in the garden and easy to grow. While bearded irises are beautiful, they do require moderate levels of maintenance. One important chore is to divide bearded irises. If not divided, the plants become overcrowded and flower production decreases. Crowded plants are also more prone to foliar diseases.To see the second bloom, the conditions must be right, with full sun and rich, well-draining soil conditions. Bearded Iris prefer at least 6-8 hours of sunlight a day.Generally, bearded irises are planted 12-18 inches apart, with the fan of leaves facing the same direction. If you have multiple cultivars, plant the different types in groups of three to seven rhizomes. After planting, water your iris and keep the soil moist (but not too wet) until new leaves begin to emerge.Bearded iris, Iris germanica, is one of the most easy and rewarding perennials you can grow. They can survive in xeric gardens with as little as 10 inches of rainfall a year, and will grow and bloom without care as long as they get plenty of sun. Multiplying perpetually, there is no limit on a bearded iris’ lifespan.Border irises are not hungry plants – just apply a layer of well-rotted garden compost around the irises, not over the crowns or rhizomes in early spring.
Do Iris reticulata spread?
When iris reticulata bulbs are happy where they are growing, they will multiply and it’s possible for them to become overcrowded. If this happens, the quality of the flowers may begin to suffer. To divide the bulbs, dig them up in late summer and split them apart. While bearded irises are beautiful, they do require moderate levels of maintenance. One important chore is to divide bearded irises. If not divided, the plants become overcrowded and flower production decreases. Crowded plants are also more prone to foliar diseases.In dry-summer climates they’re highly resistant to disease. They’re able to push back and hold their own against aggressive weeds and groundcovers, without ever becoming invasive themselves, since a clump of irises only creeps outward by about 3-4 inches per year.Poor rhizomes or bulbs are often the cause of no flowers. If these are mushy, rotten, small, and under formed, then the result is stunted plants with few or no blooms. Also, the plant needs well-drained soil in full sun for flowers to be produced. Irises in shady locations may fail to form blooms.If Iris are allowed to become too crowded the bloom will suffer, some varieties may crowd others out and disease problems may be aggravated. Depending on your location, July through September is the time to divide and transplant Bearded Iris.Evergreen boughs or straw make a good winter protection for Iris, particularly in areas with especially harsh winters. Apply after freeze-up. Heaving of the soil, caused by freeze-thaw patterns, can result in the dislodging of the rhizome.
How to grow iris harmony?
Iris reticulata Harmony bulbs should be planted 5 (12cm) deep and 2-4 (5-10cm) apart in well-drained, rich gritty soil in full sun and probably best in a raised bed or 15 bulbs will nicely fill a 9 (20cm) pot. Top dress the soil with grit so the flowers are not splashed with dirt in the rain. Plant the bulbs at 7cm (3in) apart and 7cm (3in) deep. Iris reticulata and Iris histrioides are lovely growing in shallow bulb trays topped with foraged moss – a pretty display for the doorstep.Easily grown in average, medium, well-drained soil in full sun to part shade. Soil needs to stay relatively dry in summer in order for the bulbs to set buds for the following year. Plant bulbs 3-4” deep and space 3-4” apart in fall.Height: 15cm (6). Plant Iris reticulata bulbs in late autumn, at a depth of approximately twice their own height. Choose a position in full sun in moist, free draining soil.In dry-summer climates they’re highly resistant to disease. They’re able to push back and hold their own against aggressive weeds and groundcovers, without ever becoming invasive themselves, since a clump of irises only creeps outward by about 3-4 inches per year.
Can you leave iris in the ground over winter?
Iris is cold hardy enough to be left in the ground all winter long as long as the soil has excellent drainage and no seasonal flooding during the colder months. If you have seasonal drainage issues, the rhizome of the bearded iris can be extracted and stored after the plant loses all of its top growth in the fall. That being said, you should still trim off spent iris flower stalks to keep the plants looking tidy and prevent botrytis and other diseases. The right time to remove the flower stalks is a few days after all the blooms have faded. While the flowers are beautiful, the dead flower stalks are not.During July and August the growth of iris slows. It is during this period that the clump is most easily and successfully trimmed back, dug, divided and transplanted. For the best display of flowers, iris that are growing in good conditions need to be divided every three to four years.Although irises can be transplanted at any time, they do best when established in the landscape from August to mid-October, said University of Missouri Extension horticulturist David Trinklein.Plant reblooming iris in a spot with full sun and late afternoon shade. Make sure they aren’t overshadowed by other plants that prevent them from getting the light they need. Reblooming iris thrives when given its own spot, away from other flowers. Some varieties won’t start reblooming for a couple of years.
