The old genus Scilla consists of plants grouped together only because they were mostly small and blue. Many are not actually closely related and around 16 new genera have emerged from a re-examination of Scilla. The differences that define the new genera may sound insignificant to the gardener and not all botanists agree with it, though it does seem sensible.
Schnarfia commemorates Karl Schnarf, a distinguished Austrian Embryologist, with a special interest in Scilla. It is totally European and it contains just 2 species, S. messeniaca (which is NOT Scilla messeniaca) and S. albanica.
Schnarfia scapes are semi-terete and floppy in fruit and it makes several scapes per bulb each season, which is valuable from a gardenerís point of view. The bracts and bracteoles are small. The seed capsules are succulent and the seeds are a distinctive glossy, yellow-brown with a solid appendage.
(Scilla makes one scape per bulb, terete stems which flop over in fruit, small (or no) bracts, no bracteoles. Scilla capsules are only slightly succulent, the seeds are glossy, (yellowish to) black with a soft appendage.
