Baby Dragon Hardy Citrus. Without a doubt, this contorted dwarf hardy citrus is the most contorted plant I have ever seen. The stems almost tie themselves in knots. It is truly a collector's plant as it would have very little place in the landscape except as a novelty, but it is bound to be subject of a lot of conversations. It's leaves are so tiny that they are hardly apparent, so it is obvious that it gets most of its food from the chlorophyll in its stems. And since it is so cold hardy, it will be a great pot plant that won't have to be brought in at every frost.
