Pasithea caerulea

Description:

An obscure monocot from Chile, got from Cotswold's a few years back. I haven't checked with recent studies but the last I remember was that this species was quite isolated, phylogenetically. It looks a lot like it might be a member of the Anthericaceae (if that family still stands) which I think includes things like Arthropodium, Chlorophytum and Paradisea (and Anthericum of course) but looks are very deceptive in this part of the Monocot family tree.Can anyone give me an update?It's a jolly nice blue incidentally - more intense than this photo suggests, and growing in the very poor dry soil at the foot of the south-facing wall at Pool Meadow. It's been there three years and this is its first flowering.
