SPU - Spuria Irises
Very easy, resistant and problem-free irises suitable for any sunny garden. They are undemanding to the soil, but grow best in neutral to slightly alkaline soils. The soil can be moist, but plants must not stand in water. Spuria irises love warm habitats in full sun. They are quite strong plants 80 to 140 cm high, flowering just after tall bearded irises, usually at the end of June. Plants are of tufted growth with upright, approx. 2 cm wide and 60-100 cm long reed-like leaves. The stems are the same length or about 1/3 longer than the tops of the leaves. The flowers are quite large, about 12 cm in diameter, inflorescences very suitable for cutting. The unripe fruit-stems are also decorative, well suited for drying. Spuria irises can be planted solitary or in mixed perennial beds. Of course, they could also be excellently used in urban plantings, e.g. due to their tolerance to salinity. Rhizomes should be planted 7-10 cm deep, preferably in autumn (September-October), but the plants offered here are potted in 4 liter containers, so you can plant them to the garden at any time of the year. The recommended distance between plants is 60 to 80 cm.
A significant part of the assortment of plants offered here is the result of more than 30 years of ongoing selections by Milan Blažek (Průhonice, ČR). Spuria irises are almost unknown to the public, however they would certainly deserve greater distribution and popularity not only because of the beauty of their flowers, but also due to their overall resistance and durability, which can be compared to peonies... Just another ideal plant for lazy gardeners.. ..
We accept orders all year round, plants are shipped either as bareroot (from October to the end of March) or potted (from October to May). Spuria irises will preferably be shipped as bareroot, if you want potted plants, please write a note to the order form. Once the plants start to grow in the spring, we will only ship them as potted, until they are 40 cm tall. Then it will no longer be possible to send them. Personal pick up all year round.
