How are the two forms of I. unfuicularis different? Cathy Craig President PBS Maritime zone 9b Iris unguicularis has a fairly wide distribution from N Africa to SW Turkey Greece and Crete. The N African forms are most often cultivated and have the largest flowers and long leaves to 75cm. Ssp cretensis, the Cretan form, is very much dwarfer with very narrow leaves to 20cm long (often less) and aller flowers. The larger forms provide buds on tubes long enough to be picked, an attractive centrepiece on the Christmas table if you are lucky. The very dwarf form has almost stemless flowers and is suitable for a sunny, sheltered, well drained rock garden. I believe that the Greek forms are intermediate in size. Tony Goode. Norwich UK.
