Last summer I was given some Day Lilies by my father's wife from their garden. They grow all over the place and seem to be spreading quite madly. I didn't have a suitable spot for them when I got home so I planted them in a big pot. They are now doing very well and have laves that are almost 2 dm. If I plant them in my borders, will the take over or will that take years before they spread too far.
Are Day Lilies invasive?Jump to latest post
