I bought five fennel plants to (hopefully) act as hosts for swallowtail caterpillars. But - and I have absolutely no idea why I thought this - I thought they grew to be about eight inches tall. I thought they would make a nice little border for my rock garden.
Four feet. They get four feet tall and four feet wide. So now I have to dig them up from the two square feet I planted them in and find twenty feet of garden space somewhere else. Whoops!
