How to Grow Giant Lily (Cardiocrinum)

When growing Cardiocrinum outdoors, the bulb should be planted in the autumn. Its tip should be at the same level as the soil.

If you have seeds make sure that they are fresh, and sow them out under a light soil cover, in north facing flats, covered with glass in the autumn.

Once the temperature drops below 10°C (50°F) the flats should be brought indoors, and then returned outside again in the spring (once a temperature of 10°C (50°F) has been maintained).

Throughout the process, the flats should be watered to keep moist.

Germination can take as little as three months, but it is more likely to take longer; sometimes as long as two years.
