Captured Spirit is a standard dwarf bearded (SDB) iris hybridized by Hooker Nichols (in Texas) and registered in 1980 as an early bloomer. Registered height for this variety is 13 inches, but mine rarely grows taller than six or seven inches. This may simply be the difference between growing in Texas as opposed to growing in Wisconsin.
If you make sure Captured Spirit gets six to eight hours of sun, has average, well-drained soil and some water it will reward you every spring. It is cold hardy to US Zone 3 (-40 °F to -35).
