I planted some Hubam on March 14th. Right now It is between 2 and 4 inches tall. This seems a little bit slow for a plant that is supposed to be an annual and can get over five feet tall. For those of you who have experience with Hubam does this seem about normal? Does it just all the sudden take off and grow really fast. If it doesn't grow any faster than it is right now it won't reach two feet tall. I don't have any doubt that what I planted is sweet clover, but I'm starting to wonder if it is Hubam
