Here is a delicate beauty: Autumn Crocus (Crocus speciosus). The advice from Shipton Bulbs is to grow in grass that will not be mown. I planted a handful in just such a spot; I will plant some more next year seeing how lovely they are at a time when not much else is in flower.

 Said to have bluish flowers but these are on the violet spectrum to my eye. Strongly resembles the paler forms of Crocus tommasinianus which flowers in very early spring. They are near neighbours in their natural habitat which might explain their similarity?

C. speciosus hails from Crimea/Iran/Turkey and C. tommasinianus is native to Hungary/Bulgaria.
