Was just wondering, planted some alliums in bulb form and would like to know how from growing from seed it then turns into a bulb.
From seed they take a few years to develop into a viable bulb Tina. Sowing in a seed bed is the usual way of raising them from seed. Different varieties take differing time periods to fully develop so it's often easier to buy in mature bulbs, unless you have free space to let them get on with it.
If I understand your question correctly Tina you're asking how it does it.
When the seed germinates it put a shoot up and a root down. A bulb is the expanded base of the leaves and it grows layer by layer over a few years til it's big enough to flower
Thanks loads for your response, so it will take a lot longer to form a flower,
Planted some alliums that are the size of tennis balls, well impressed. It will be a nice challenge to produce some more from the two I have.
If you have any of the cultivars what you get from seed won't be quite the same but a lot of them are near enough to make a good show
