There are many ornamental alliums that look and smell a lot like leeks. Even though I've grown several varieties of edible garden leeks, I can not tell if that is what you have. Also, I don't know if the ornamentals are edible or dangerous. So don't eat them unless you know for sure what you have.

Garden leeks will also grow large lovely flowers, usually white. They are on tall hollow stalks that often flop over if not staked. All of this is similar to many decorative varieties. At least let yours grow and find out about the flowers and size before you make a decision.

And the best choice might be to use some of your planting space to sow some seeds from known leek varieties and get leeks you know are safe.

Agreed. To me they look like leeks but then for some reason they also look a bit off. Best not to try them at this point.

Thanks for your replies! I'll wait for them to bloom and see what happens. They are near some old defunct shaded garden beds that I bet had food once, and their distribution pattern looks more like they went to seed than were spread by division/squirrels, so they could just be runaway volunteers. But I'd rather not poison myself! Hopefully these actually will bloom, unlike the mystery bulbs at my old house >:(

Chances are they are ornamental alliums. If so the display should be fantastic. As I understand it all true alliums are more or less edible, but some taste much better than others.

Well, update on my mystery plants. They are certainly getting bigger... A LOT bigger. No sign of a bloom yet!

They sure have grown some! Very few true alliums are actually poisonous, but some will cause gastro-intestinal distress, which some folks are more susceptible to than others. Some of the ornamentals can actually also be eaten and are in some places. Most wild alliums in fact were collected for eating by which ever local peoples were around them; so it is no accident that we have quite a variety of alliums in our edible gardens.

Yeah, I'm curious to see if I get any blooms. I did find an old buried tag for some tomatoes over there, so someone had a veggie garden at some point, but I'd hate to eat them if they're gonna put on a show!

Please let me know what you found out about the Leeks??? or what every you found.
