I moved into a new home in July. There were about 15 of these growing outside around a pole. They stand about 2 feet tall and have thin leaves all the way down the stem. They smell wonderful, too. I have been trying to figure out what they are with no luck. Someone said Allium, but I don't think so. At least not what I have saw online. I read Allium smells like onion when you break the stalk.....this one doesn't. I love them and want more. If someone knows please let me know. And if you know, how do I get the seeds to replant some? Thanks a bunch!
