Seed Raising Advice

Allium hollandicum seeds need a period of moisture and cold to break dormancy, before they will germinate.
The period of dormancy can be provided by placing the moistened seed in a refrigerator. Put the seed into one fold of a moistened paper kitchen towel, folded into 4 ,and which has been gently squeezed to eliminate most of the water, seal the paper towel & seeds in a plastic bag and leave in the refrigerator door at around 4 to 5°C for 2-3 months. Inspect from time to time, and if any have sprouted lift them out carefully, pot up, and propagate at 5-12 deg. C. After this time remove to 5-12 degrees for 2-3 months. Repeat the  cold and hot process if there is no germination.

Germination is often erratic and may take some time.
