Wow, something very unusual...From a fat, fleshy rootstock grow tufted rosettes of shallow to deeply toothed, reniform leaves. The erect to decumbent stems have smaller, short-stalked, lanceolate leaves and are 2-4” inches long. Tight, globular heads of 20 or more flowers, each to 1” inch long, are held at the ends of each stem, and each flower is a delicate object in itself. A pale lilac inflated flask or club-like base that, as it tapers to a very thin neck, changes color to a deep or almost blackish purple. From the end of the thin neck protrudes the deep purple forked and twisted stigma.
It grows in narrow, lofty crevices of limestone cliffs in the southern Alps and the Dolomites to around 2000 m, where the roots creep through any narrow cracks and anchor the plant firmly to the rocks. There is no humus in the crevices, but a very sandy substratum. It prefers to grow on shady, damp, limey rocks and does not like low winter temperatures nor dry, hot summers, but a humid and cool climate. Very rarely white forms or red colored may occur. Zones 5-8.
This is not an easy plant to grow. It needs slug protection and is best placed in a crevice or containers.
