I just bought 'Feelin Blue' which is a dwarf conifer with an expected height of 1'. I added some info to the database and noted that it is classified as a tree. I didn't propose a change to a shrub, which is what I think of it as, and am wondering if all dwarf conifers are considered to be very short trees? Interesting if so. Which then begs the question: how does one differentiate a shrub from a tree?
