This was the Ornithogalum a month ago – here it is today:
It continued blooming while I was away (cared for by my next door neighbour) and I’m guessing it will last a few more weeks! Amazing.
It’s a bulb so I’ll try to keep the foliage going for a bit before letting the plant die back. If I’m lucky, the bulbs will survive till next fall when I’ll replant them and see if I can encourage them to bloom.
