I planted a few freesia corms a couple of years ago, and they seem to enjoy the lack of care they are getting here. The only problems I have is that they are often in bloom early in spring before I come to Greece. This year we were here for Easter, and they were very colourful. Don't ask me which species, I got the corms at the local marked. Anemone coronaria also does well here, and this spring I saw they they had spread themselves to the field around the house, they were in bloom at the same time as the freesias. Another spring flowering bulbous plant doing well here is a Gladiolus, which has found its way from the wild and into our garden, they grow abundantly in the wild here. I am not quite sure which species it is, Oron says it is probably G. communis, but it might also be G. imbricatus, I would be very happy if anybody had anything to add here, see photos.
At the moment there are lots of cannas everywhere, also in pots, they are very colourful, but I suppose they need some water. I planted a couple this summer, I am interested to see if they will survive the period when we are not here
