right here..... lol. Gabriel, as a rule SDB's have smaller rhizomes than TB's. However if I get an SDB from a company that has TB's the size of my head then their dwarfs are going to look like an average TB rhizome. If I have leftovers from a planting and cannot id the immature TB rhizomes from the mature SDB rhizomes I can tell which is which in the spring long before bloom time by the foliage. All of the median foliage is smaller than the TB's and most of the leaves are narrower. My tiniest rhizomes are the MDB's. Some of these never get bigger than my little finger and some of the blooms will not exceed the size of a quarter. The older dwarfs have leaves growing upwards and are around 14 - 16 inches high. The newer ones have short wide fans and the are usually 10-12 inches high. They range down to 8 inches before they get shorter and are classified as Miniature Dwarfs or MDB's. When yours start growing and blooming you are going to quickly become an expert. smiles
