How to Grow Mountain Lily, Tartar lily and other Ixiolirion Plants in the Garden

The bulbs of tartar lilies (Ixiolirion Plants) should be buried about 5 cm deep and at 10 cm apart in the spring; into a sunny part of the garden.

Ideally the soil should be dry and sandy. If you are growing Tartar lilies and other Ixiolirion species members from seed then sow on the surface and lightly cover the seed; this should be done before the last frost of spring.

If you are first planning to grow Ixiolirion indoors then they should be started about two to two and a half months before putting out (following the last frost of spring). Tartar lilies will take from one to three months to germinate at a temperature of 10 degrees centigrade.

Caring for Tartar lily and other Ixiolirion Genus Members

Once growing it is necessary to apply a top dressing of manure in the spring. In very cold areas bring the bulbs of Ixiolirion indoors and store in a cool dry place through the winter.
