Tiarella trifoliata (lat. Tiarella trifoliata) - decorative culture; a representative of the genus Tiarella of the Saxifragaceae family. A species common in the humid forests of western North America. It has several varieties and varieties that are very similar in appearance to Heykherells.
Characteristics of culture
Three-leafed tiarella is represented by small herbaceous plants with simple or three-leafed leaves, sitting on short petioles. Plants are equipped with stem and root leaves, the first can be in a single copy or up to four pieces. The leaves are relatively large, up to 15 cm long.
The flowers are equipped with lobular bracts, a bell-shaped glandular-pubescent receptacle, an actinomorphic corolla, linear or subulate petals, and a calyx with folded sepals. The flowers are collected in paniculate inflorescences, towering above the foliage on peduncle stems. Flowers sit on glandular-pubescent whitish pedicels. The fruit is a small capsule containing 2-6 ovoid seeds.
Three varieties of tiarella three-leafed have been identified:
* Tiarella trifoliata var. laciniata - this variety of thiarella is represented by low plants with three-leafed leaves, the leaves of which are divided into lobes, and the leaf located in the middle is serrated;
* Tiarella trifoliata var. unifoliata - this variety of tiarella is represented by plants with simple leaves, less often divided into three lobes;
* Tiarella trifoliata var. trifoliata - This variety of thiarella is represented by plants with three-leafed leaves, divided into shallow lobes.
There are also many varieties on the market, some of which are deep pink in color, such as the Incarnadine variety. The rest of the varieties are difficult to distinguish from Heycherell.
Use in the garden
Tiarella three-leafed is a shade-loving crop. Most often it is used to decorate shady areas and areas under the crowns of trees and shrubs. Like Heycherella, Heuchera and Hosta, three-leafed tiarella becomes more lush and attractive with age, however, at the age of five, the bushes are divided into 2-3 parts and transplanted. This procedure is required to improve the ornamental properties of plants, because by the age of five the rosettes fall apart, and their center is exposed.
Because thiarella trifoliate is tolerant of almost any soil, it can be grown in heather gardens. Acidic soil will not harm plants. Also, the culture goes well with various perennials and ornamental shrubs, for example, ferns, astilbes, hosts, heycherells, heucheras, brunners, mahonia, barberry, spirea, rhododendrons, etc. Tiarella will decorate the borders and edges of garden paths. In autumn, the foliage of tiarella three-leafed becomes copper, brown and bronze, which makes it look even more interesting.
Even without fragrant buds, the plants look very attractive. And most importantly, nothing can spoil this beauty, because the culture is resistant to diseases and pests. And she also does not need special care, enough watering and periodic hilling. Three-leafed tiarella is relatively winter-hardy, but it can suffer from severe frosts, therefore it is very important to mulch the plants with peat or a thick layer of dry fallen leaves before the onset of persistent cold weather.
Landing features
There is nothing difficult in planting and transplanting an unpretentious three-leafed thiarella. It can be planted in any area, however, moist, loose, drained, permeable, loamy soils are welcome. The culture will not put up with compacted and dry soils, it will look defective on them. But acidic and infertile soils are quite acceptable, although the introduction of organic matter in the form of compost or humus is desirable.
It is enough to carry out the feeding procedure once every 1-2 years. Thiarella is planted in pre-prepared holes, which are filled with soil mixed with humus and wood ash. Immediately after planting, the soil is watered abundantly. In general, the first 2 weeks of watering are very important for plants, they will speed up their survival in a new place.
