Tiarella polyphylla (lat. Tiarella polyphylla) - decorative culture; a representative of the genus Tiarella of the Saxifrage family. It is a native of the subtropical forests of eastern countries, including Japan and China. The species is not winter-hardy enough, but under the condition of good shelter it winters even in regions with cold winters.
Characteristics of culture
Tiarella multifoliate is presented in the form of herbaceous low-growing plants with lobed leaves, rounded in outline and pink flowers, collected in graceful racemose inflorescences, developing at a height of 40-50 cm. The rosettes of leaves themselves do not exceed 20 cm in height. Tiarella multifoliate is one of the shade-tolerant plants that can decorate any inconspicuous corner of the garden. She is unpretentious, caring for her does not take much time.
Tiarella is ideal for those gardeners and florists who do not have much gardening experience and do not have enough time to care for their garden dwellers. After all, thiarella is unpretentious and resistant to diseases and pests, and its lush rosettes can suppress the growth of weeds and retain moisture in the soil for a longer period.
Thiarella is also undemanding to soil conditions, but nevertheless it develops better on moisture-consuming, loose, drained, permeable, neutral, slightly alkaline or slightly acidic soils. On porous and sandy soils, plants feel defective without enough moisture. Lack of moisture will affect the development of culture and flowering. In addition to watering, periodic hilling is important for tiarella. The fact is that as it grows, the base of the outlet is exposed, as a result, the bushes lose their decorative effect.
As already mentioned, the multifoliate thiarella cannot be called a frost-resistant crop; it should be covered for the winter. In the spring, the shelter in the form of a thick layer of dry foliage or peat is removed, but not immediately, because during the melting of the snow, the foliage of the plants begins to intensively evaporate moisture, which leads to dehydration, and subsequently to death. If you shade the plants for this time and regularly water, this problem can be avoided.
Reproduction
Thiarella multifoliate is propagated by seeds and vegetatively, the second method is used most often, especially since the rosettes of leaves grow strongly by 4-5 years and need to be divided. One bush is divided into 3-4 parts, the division is carried out with a sharp knife, pre-treated with a disinfecting solution.
The plots are immediately transplanted into planting pits measuring 20/30 * 20/30 cm, at the bottom of which a small hill is formed from a mixture made up of excavated soil, wood ash, compost and complex fertilizer. In the future, mineral fertilizers do not need to be applied, organic matter - once a year.
It is important to remember that division should be done before flowering. During flowering, this procedure cannot be carried out. The seed method is also effective, only it is used infrequently. Seeds are sown in open ground in April-May under the film. Seed preparation is not required. Since the seeds of tiarella are very small, they are mixed with washed river sand before sowing. So the seeds are distributed more evenly over the soil surface.
Use in the garden
Tiarella multifoliate, like heart-shaped tiarella, is used in ornamental gardening. She is good in both single and group plantings. It can be safely planted under the crowns of trees and large shrubs in alliance with heathers, bells, incense and cereals. Since thiarella is hygrophilous and does not tolerate drought, it is recommended to use it to decorate the shores of an artificial reservoir.
It will also be appropriate in rock gardens, rockeries and borders in compositions with heuchera, heycherella, ferns, hosts and astilbe. Tiarella will look great in conjunction with conifers. Thiarella is shade-loving and can be used for landscaping shady areas, such as behind tall buildings where there is very little sunlight. It should be noted that thiarella is durable, it is enough to carry out constant division, then the plants will delight with their beauty for decades.

Many-leaved Kalmia (lat.Kalmia polifolia) - an evergreen plant with a compact and dense crown from the Kalmia genus, which is listed in the Heather family (Latin Ericaceae). Unlike many species of the genus Kalmia, which prefer well-drained soils, which guarantee the absence of destructive dampness, the multifoliate Kalmia chose the cold swamps of North America for its life.
Lupine Multifoliate
Lupine multifoliate (lat.Lupinus polyphyllus) - the most spectacular species among the plants of the genus Lupine (lat. Lupinus), which is part of the legume family (lat. Fabaceae). In addition, compared to many species that are annual plants, Perennial Lupine is a perennial plant.
Tiarella
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.
Mary Multifoliate
Mary multifoliate (lat.Chenopodium foliosum) - one of the most interesting representatives of the Mar genus of the Amaranth family. Often the species is called vines jminda, rod-shaped jminda, strawberry spinach. The homeland of the plant is considered to be European countries, to be more precise, those located in the south.
Multifoliate Clover
Multifoliate clover (Latin Trifolium polyphyllum) - a herbaceous perennial plant from the genus Clover (Latin Trifolium), belonging to the legume family (Latin Fabaceae). This species changed the traditions of most species of the genus, replacing the trefoil with a complex leaf with numerous leaves on one petiole.
