Miniature dwarfs don't have branching, but I believe they do typically have two buds per stem. Standard dwarfs generally do have branching and may have 4 or more buds per stem.

Both MDB and SDB tend to be very vigorous growers, quickly forming tight circular clumps with numerous bloom stalks. The longevity of each individual bloom can vary from a few hours to a few days, depending on climatic conditions (just like any other iris). Also, like any other iris, they provide only one bloom stalk per rhizome.

A mature clump of MDB or SDB may be covered with blooms for several days, with lighter bloom prior to and continuing after the peak flush. Some MDB and SDB clumps bloom more sequentially over a longer period without ever having a visual peak.

In general, both MDB and SDB provide brilliant displays of color in early spring before any other beardeds start blooming. Due to their short stature, they should be placed at the front of a border, iris bed, or rock garden.

You'll love them! I couldn't get through the winter/spring transition without my MDBs and SDBs to lead the way.

Thank you Laurie -- that's exactly what I wanted to know! I'm placing my order tomorrow. I can hardly wait for spring!

Some of the newer varieties will also put up more than one bloom stalk per rhizome. Either at the same time, or as a rebloom stalk.
