Intermediate Bearded stand from 41 cm (16 inches) to 70 cm (27 1/2 inches) high, with their bloom season overlapping the SBDs and the TBs. Although the IBs show their dwarf ancestry in early bloom season and very interesting color patterns, they are large enough that their individual stalks may be nicely branched, forming an elegant bouquet. Some varieties are nicest in clumps, where they present a large amount of color (like the SDBs), while others are showiest in specimen plantings, where the stalks and individual blooms may be seen to best advantage. The highest award given is the Hans & Jacob Sass Medal.
