Plant characteristics and classification of heucherella
Plant order, origin and occurrence of heucherella
The heucherella (Heucherella tiarelloides) is a plant that does not exist in nature. It is the result of the crossing of an alumroot (Heuchera) with a foamflower (Tiarella). Both plant genera are native to North America and both belong to the saxifrage family (Saxifragaceae). Horticulturists quickly recognized the high potential of these plants, as they hybridize very easily, i.e. they produce offspring with specimens that are foreign to the species. To combine the best of the two genera Heuchera and Tiarella, they crossed them and the result was x Heucherella tiarelloides. The x in front of the species name means that it is a genus hybrid. Also, the name heucherella is a combination of the two parent species Heuchera and Tiarella.
Characteristics of heucherella
Heucherella cultivars form compact, wintergreen leaf clusters, from which the upright, 20 to 60 centimeter (8 to 24 in) high flower stems grow during the flowering period. In spring, they sprout fresh again.
Like the name, also the leaves of the heucherella reflect the combination of the two genera. The intense coloration of the leaves is an inheritance of the Heuchera parent, while the dark veined leaf patterns were adopted from the Tiarella parent. They are also deeply lobed, similar to these. Outside the flowering period, the leaves make up the great ornamental value of these perennials. They are especially colorful after new shoots in spring and autumn.
Usually the flowers of the heucherella appear between May and July in grape-like inflorescences, so-called racemes, at the end of thin, upright stems. The individual flowers are tiny bells in white or pink.
Heucherella cultivars are sterile and do not produce fruits and seeds.
Heucherella – cultivation and care
The heucherella thrives best in partially shady areas. Shady places are still more likely to be tolerated than too sunny places.
Any normal, nutrient-rich garden soil is suitable for the cultivation of Heucherella. Good water permeability is important, because the perennials do not tolerate waterlogging.
The best planting times for heucherella are spring and autumn. Heavy soils should definitely be made more permeable with sand or gravel. In the weeks following planting, please ensure that the soil has an even moisture content. As planting distance 25 centimeters (10 in) are recommended, when used in a large area, 15 plants per square meter (10 sq ft) are expected.
Only in cases of persistent dryness, water must be added to prevent the soil from drying out. The rootstock tends to push itself out of the soil over time. Therefore, it should be heaped up with bark humus or compost in spring. Then it is also time to remove the dried leaves from the previous year to make room for new shoots. After flowering the stems should be cut off close to the ground.
In order to maintain the vitality of the perennials, it is advisable to divide heucherellas every three to four years. To do this, dig out the rootstocks after flowering or in autumn and divide them with the spade leaf.
The easiest way to propagate Heucherella tiarelloides is to divide the root ball.
Diseases and pests
Root rot can occur on soils that are wet from stagnation. Like the parents, the heucherella is quite resistant to snails, but is unfortunately attacked by the vine weevil more often. Above all its larvae damage the roots.
Above all rough situations and dryness can cause problems for Heucherella-breedings. Therefore, a brushwood cover is suitable. Please make sure that the soil does not dry out completely. Potted specimens should be placed in a protected corner during the cold season.
Use in the garden
Heucherellas are leafy ground-covers under loosely planted shrubs. Good partners are hostas, ferns, astilbe, bleedingheart, Jacob’s Ladder, lungwort and Solomon’s-seal. Planters can also be varied with the compact perennials.
