The ivy alia (× Fatshedera lizei ) is a hybrid of the indoor aralia ( Fatsia japonica ) and the common ivy ( Hedera helix ). It was created in 1912 and has been cultivated as a houseplant since 1926 .
description
The ivy alia is a climbing shrub that grows up to 1.2 meters high. The shoot axes remain brownish, are weak and often hang down; young stems have rust-colored flowers. If the plant is tied up, it can reach a height of 3 to 5 meters as a climbing plant . Unlike ivy, however, the ivy alia does not climb without help.
The leaves are three to five-lobed and about 20 centimeters long and up to 30 centimeters wide. The petiole measures between 5 and 20 centimeters and has three horn-like extensions at the base. The color of the leaves varies depending on the cultivated form from dark green to the white or yellow spotted variegata form . They are slightly hairy .
The inflorescences are umbrella-like, spherical umbels . The pale green flowers are about one centimeter in diameter. No fruits are formed.
The number of chromosomes in ivy varies between 2n = 72 and 2n = 98, with many aneuploid forms in between . The number of chromosomes in common ivy is 2n = 48 in common ivy. It is therefore assumed that Fatshedera lizei is an unstable tetraploid form, and thus an addition bastard .
Origin and system
The ivy plant originated in a nursery in Nantes in 1912 and was presented by Lizé Frères at an exhibition that same year . He stated that the hybrid came about by chance from Fatsia japonica 'Moderi' as the seed plant (mother) and Hedera helix var. Hibernica , the Irish ivy, as the pollen plant (father). When the plant was shown again at the Génèrale d'Horticulture Exposition in Paris in 1923 , however, there were contradicting statements as to whether the hybrid was accidental or artificial.
In the same year, the hybrid was first described by André Guillaumin under the name Fatshedera lizei . The name is derived from the names of the parent plants. The plant was not spread in culture until 1926.
Cross-genus hybrids are very rare among the seed plants , with the exception of the orchid family (Orchidaceae). For this reason, the genesis of the hybrid was repeatedly rejected. Francis Ballard in particular had doubts about the status of the hybrid. Micromophological and cytological studies have now confirmed the status as a hybrid of Fatsia japonica and Hedera helix .
use
The ivy alia is often planted as an ornamental plant in gardens or indoors.
