Description
(Biarum tenuifolium ssp. arundanum according to some)
Rounded but quite narrow leaves on short stalks with very upright growth. There is also a short stalk below the inflorescence which is deep purple-black, as is the protruding spadix, although this can also be an olive colour, or olive-purple with a darker (or lighter!) base. There is simply a degree of natural variability. At the base of the spadix, the lower sterile flowers in the species are supposed to be in whorls.
This is a summer-flowering species which is proving to be a good bulb-frame subject. It can also be grown in a pot if kept frost-free, since a pot is easily frozen through regardless of species. B. arundanum may even survive outside in the UK in a south-facing, sunny, well-drained spot with deep planting.
A Spanish species from the area around Ronda, in the south of the country, the home of many, fabulous endemic plants and these are vegetative propagations from plants first found many years ago in the Serrania de Ronda.
For those interested it appears than the species is normally diploid with 2n=22.
