I planted some Allium Hollandicum "purple sensation" last year and they are just coming into bloom. Can anyone tell me if these plants are edible?
Why would you want to?
Try onion or garlic.
Wild garlic is delicious and I was hoping that it might be possible to use other alliums in the same way, in salads, soups etc
I don't think any Alliums are poisonous [that is to humans, we are unusual as they are very poisonous to most mammals including cats and dogs] but I think there is a very good reason our ancestors chose onions, leeks and garlic to eat - they taste better.
You can sprinkle the flower heads in salads, but I use chive flowers for that. The leaves are already going over. Given the cost of purple sensation, I would let the leaves die down to make the bulbs stronger for next year.. They make good cut flowers for the house if you have excess.
