The study of some species and cultivars of Heuchera growing in Iaşi conditions

Abstract

The genus Heuchera (fam. Saxifragaceae) includes over 53 species of perennial herbaceous plants with persistent leaves. Plants of this genus form globular bushes with heights between 15 - 25 cm and the diameter between 15- 50 cm. Although the main ornamental part of the species and cultivars of Heuchera is represented by leaves, because of their shape and color, the decorative value of the flowers can not be neglected. In this paper were studied some morphological characters that give ornamental value to Heuchera plants (bush diameter, leaf size, number and size of flowers and inflorescences). Observations were made on five Heuchera cultivars grown in the field, in conditions of Iasi (H. sanguinea 'Coral Forest', H. hybrida 'Mini Monster', H. hybrida 'Venus', H. hybrida 'Marmalade' and H. hybrida 'Pewter Purple'). The highest number of leaves and most compact bushes stands out 'Mini Monster', and the best flowering capacity had 'Mini Monster' and 'Venus', while 'Marmelade' has formed fewest inflorescences.
