Allium

I had a fantastic show of Alliums this season from beautiful majestic flowers to when all the plant turned brown and the stalk of the plant could be lightly removed. This time I have kept all of the seeds from the flower head. My question is m can I re plant these seeds next year and in doing so create more beautiful Alliums

    Alliums grow easily from seed but the fancy named cultivars will not seed true. Sow them now (or just let them seed). It takes from 2-5 years from seed to flower, the small ones are quick, the larger ones take longer

    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.
