Tips on growing alliums (purple sensation) from seed?

Hi all. I have recently hung a couple of seed heads in a paper bag and shaken the dried seeds into a paper envelope for storing over the winter.
Any advice from otgers that have grown these from seed before would be much appreciated. I'm guesding i sow tgem in pots in spring and transplant out when developed / frost has passed? Will tgey flower in tgeir 1st year, or 2nd year?
All good growing tips appreciated!

    As flowers come from bulbs, it will take 3/5 years for a flower to appear

    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 damaged, 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.

    I leave the flower heads in the border and every year it's covered with small Allium seedlings.
