    they can, but they are usually grown from the existing bulbs. They will die down to leave a bulb in the soil for next year.

    I think I have posted this on here before, but I will do it again to save searching.

    I have grown dozens of varieties of Alliums from seed over the last cough cough years. It is reasonably easy, but the bigger the bulb the longer the wait for flowers. So here goes
    Sow the seed fresh. It germinates better straight from the plant rather than being dried off.
    Cover lightly with grit, gravel or whatever rather than compost.
    Sow in a deep pot rather than a seed tray (reasons later).
    Leave exposed to weather. They need a period of cold followed by warmth to initiate germination.
    When (if?) they germinate do not be in a hurry to p rick them out. This is the reason for deep pot rather than seed tray. They have only one root to begin with and if it is damage, it dies and a new one has to be produced from the base of the seedling. usually they die.
    Feed the seed pot with dilute Baby Bio type stuff, until the leaves go yellow then allow the pot to dry off.
    Repotting may be done when they are dormant. Some types never really go dormant so be careful.
    I often do not repot until they have had another seasons growth. Remember many of them actually grow in late winter/early spring.
    Cannot think of anything else for the moment.
    Not as hard as it seems. Oh and since they are almost always self pollenated you get what you sow, no variations. UNLESS you have been given some Allium flavum hybrids in which case.................

    hi, thanks for the response,is now the right time to try this?

    The seeds are black when they are ripe and that is the time to sow. Mine are still green so not ready yet.
