Fatshedera lizei

Lobed leaves of a variegated variety of Efeuaralie ( × Fatshedera lizei ).

The Efeuaralie ( × Fatshedera lizei ) is a hybrid of the Zimmeraralie ( Fatsia japonica ) and the commons ivy (Hedera helix). It is created in 1912 and since 1926 as a houseplant in culture.

Description

The Efeuaralie is reached up to 1.2 meters a rank growth of shrub heights. The Stems remain brownish, are weak and often hanging down; young stems are beflaumt rust. If the plant is tied up, they may reach a climber a height of 3 to 5 meters. However, unlike the ivy climbs Efeuaralie not without help.

The leaves are three-to five-lobed and are about 20 inches long and up to 30 inches wide. The petiole measuring 5-20 cm and carries at the base of the three horn -like extensions. The color of the leaves varies depending on the breed form from dark green to white or yellow spotted Variegata form. They are slightly hairy.

The inflorescences are umbrella-like, globular umbels. The pale - green flowers have a diameter of about one centimeter. There shall be no fruit.

The chromosome number of 2n = Efeuralie varies between 72 and 2n = 98, with many intermediate aneuploid forms. When Ivy Commons, as well as in the Zimmeraralie, is the chromosome number 2n = 48 It is believed, therefore, that it is Fatshedera lizei an unstable tetraploid form, and thus to an addition bastard is.

Origin and systematics

The Efeuaralie was established in 1912 in a nursery in Nantes and was introduced in the same year of Lizé Frères at an exhibition. He stated that the hybrids randomly from Fatsia japonica ' Moderi ' as seed parent (mother) and Hedera helix var hibernica, the Irish ivy, as pollen parent (father) was created. When the plant was shown in 1923 at the Exposition générale d' Horticulture in Paris again, but there was conflicting information about whether the hybrid was developed randomly or artificially.

In the same year, the hybrids of André Guillaumin was first described under the name Fatshedera lizei. The name is derived from the respective names of the parent plants. The plant was only in 1926 circulated in culture.

Cross- species hybrids are very rare in the seed plants, except the orchid family ( Orchidaceae). For this reason, the history of the hybrids was repeatedly rejected. In particular, Francis Ballard doubted the status of the hybrids. Mikromophologische and cytological studies confirm now but its status as a hybrid between Fatsia japonica and Hedera helix.

Use

The Efeuaralie is often planted as an ornamental plant in gardens or in the house.
