Ipheions originate in South America but seem hardy enough, certainly providing invaluable early colour. They have a garlic smell when bruised that is not unpleasant. I have a number of varieties. They do not like over rich soil, getting rather leafy and failing to support the flower. I shall grow mine in a more gritty soil in future, cutting back on the feeding. They certainly increase quickly. To show the various colours, here is 'Charlotte Bishop', 'Froyle Mill' and 'Wisley Blue', the middle one just showing colour.
