Ledebouria grandifolia

The flowers appear Ledebouria-like to me, albeit more showy than usual. An
internet search shows very well an isotype of H. grandifolius, with the
broad leaf blades abruptly narrowed to a slender petiole, closely
resembling some eriospermums. Haemanthus leaves are broad and truncate at
the base (leaf pairs forming a 'seam') although Balfour was likely
referring to what we now call Scadoxus, which have leaf blades attenuated
at the base. Harry Jans's lovely photo taken in Oct/Nov would be at the
beginning of the (main) winter rainy season, with leaves just emerging.
Flowers may also appear, perhaps more typically, before the leaves (like
Haemanthus). Therefore it is not surprising that the type gathering was
sterile (no flowers or fruits) and it was thought to be a Haemanthus rather
than a squill.

By all accounts L. grandifolia is a difficult plant to maintain in
cultivation. Bulbs collected by John Lavranos on the 1967
inter-disciplinary expedition to Socotra reportedly withered away over a
period of years. My own experience is that it will remain dormant for 2-4
years at a time, even with coaxing by autumn watering, producing a leaf or
two when it is in the mood and not otherwise.
