Tiarella (lat. Tiarella) - long-term decorative culture; genus of the family Saxifrage. The genus includes only 6 species, of which 5 species are naturally found in the humid forests of North America, and one species in the mountainous regions of Korea, China and Japan. Externally, the flowers of tiarella are very similar to small turbans, which is why the plants were given this name.
Characteristics of culture
Tiarella is represented by herbaceous evergreen or semi-evergreen plants with a weak root system and a growing rosette of leaves. The leaves are five-lobed, pubescent, with contrasting patterns or spots along the veins. Outwardly, tiarella looks very impressive, like an openwork coverlet, above which flower stalks about 10-15 cm long, bearing whitish-cream or light cream inflorescences, rise.
Tiarella is a genus worthy of the attention of gardeners and florists, despite the small number of species, there are many varieties that differ in the color of the foliage and the size of the bush. Tiarella is durable and highly decorative, with age it becomes more attractive and lush. She is able to decorate not only flower beds, but also the sides of paths and unsightly areas in the tree-trunk circles. She is tolerant of the shade, and after all, not all soil plants, to which the genus in question belong, can boast of such a characteristic.
Views
* Tiarella polyphylla (lat. Tiarella polyphylla) - the species is represented by herbaceous soil plants with pink flowers, collected in inflorescences, rising above the mass of leaves to a height of 50 cm. Non-frost-resistant species.
* Tiarella unifoliate (Latin Tiarella unofoliata) - the species is represented by large bushes reaching a height of 40-45 cm. The species is actively used by Russian gardeners.
* Heart-leaved tiarella (lat. Tiarella cordifolia) - the species is represented by plants up to 20 cm high with rounded heart-shaped foliage with bronze or reddish-brown veins and star-shaped pale cream or white flowers, collected in racemose inflorescences.
* Three-leafed tiarella (Latin Tiarella trifoliata) - the species is represented by plants with three-lobed leaves and pink flowers (sometimes of a different color). Relatively winter hardy species.
* Tiarella Verri (Latin Tiarella wherryi) - the species is represented by small bushes up to 30 cm high with white or pink star-shaped flowers, collected in racemose inflorescences.
It should be noted that tiarella is best planted separately from other crops, as it grows quickly and fills large areas. Therefore, it is often planted under the crowns of trees, in this form it looks like a kind of lawn. There are many varieties and hybrids on the market today that are attractive due to the unusual shape of the foliage and its color. But nevertheless, the most popular among gardeners is heart-leaved tiarella, it is distinguished by high winter-hardy properties and decorativeness from early spring to late autumn.
Growing features
Tiarella cannot be called a whimsical culture, it can develop normally in shady areas, but a sunny location will not harm her, however, with shading at noon hours. In sunny areas, tiarella foliage will be more saturated, and abundant flowering can be expected. Soils for growing crops are preferably loose, drained, moderately moist, permeable, processed, slightly alkaline or neutral. Too porous substrates are undesirable, especially if the plants are planted in an area open to the sun.
Care
There is nothing remarkable about caring for tiarella. It is important to provide feeding twice a year - in the spring and after flowering. Watering as needed, overflow is undesirable. Plants should be hilled annually, this procedure plays an important role in the decorativeness of the culture and its active growth. The same procedure is very important for relatives in the family - Heycherella and Heychera. Some species, as already mentioned, are winter-hardy, but in cold regions it is advisable to cover the bushes with dry fallen leaves. You can also use non-woven fabric. With the onset of spring, the shelter is removed, but not immediately, but only after the soil has warmed up. You should remove the shelter gradually, and it is better in cloudy weather.
