Eranthis cilicica.

Eranthis cilicica.

 I have much more success with Eranthis cilicica than Eranthis hyemalis. It is such a joy to me when they push their noses through the soil and unfurl their ruff, with these lovely bright yellow flowers on top. Its feels like I have never seen them before, I'm sure gardeners know what I am saying.  I grow them in a trough with Hepatica japonica and Hacquetia epipactis Thor, their leaves shading them in summer, they are watered all through the months of summer.
Eranthis cilicica leaves have many divisions, sometimes tinged with bronze as you can see on the last photo. Coming from Turkey, Iraq to Afghanistan in a variety of habitats, in alpine pastures, hill slopes and the outskirts of woodland areas. Many botanists consider E. cilicica to be a synonym E. hyemalis, but it is separated by the more finely divided foliage, shorter stature and larger flowers. The hybrid between Eranthis hyemalis and Eranthis cilicica is Eranthis x tubergenii. We would not have Eranthis x tubergenii at all if we didn't have E. cilicica and E. hyemalis these two species hybridise to produce Eranthis x tubergenii with large flowers and it is scarce as propagation is only by division.
It dates from before 1924 when the great plantsman E.A. Bowles called it Eranthis 'Tubergen' for C.G. van Tubergen  who first introduced this interspecific cross about 1923.
I do not think Eranthis x tubergenii is in Australia.
