These grow wild and prolifically in this area. They are found in masses growing in shady but dry limestone outcroppings. Their delicate flowers are most spectacular up close, and in mass. Relatively easy in culture, mine was roughly transplanted from the crevice of a rock.

Mostly they are propagated by seeds, but every so often it will divide. Mine has a division, this is it's second season and the division still doesn't bloom.

Seed - best sown as soon as it is ripe in a shady position in a cold frame. Water lightly in summer, it should germinate in autumn or winter. Stored seed requires a period of cold stratification. Sow as early in spring as possible in a cold frame. Sow the seed thinly so that it will not be necessary to prick them out for their first year of growth. Give an occasional liquid feed to the seedlings to make sure that they do not become nutrient deficient. When the plants are dormant, pot up the small bulbs putting 2 - 3 bulbs in each pot. Grow them on in a shady position in the greenhouse for another 2 3 years and then plant them out into their permanent positions when they are dormant in late summer. Division of the bulbs in the summer as the leaves die down. Larger bulbs can be replanted imm... read more
