This is my first year with MDB's, and I am finding some nice surprises with these, the smallest of irises. First I find them to be very hardy, having endured their first winter at their new home away from Oregon. I also noticed their willingness to bloom after less than 10 months in the soil! Alpine Lake bloomed today with four open flowers! That is remarkable, since I sometimes wait two years for a new TB to bloom. The following is from the American Iris Society's Checklist data base: (A. & D. Willott, R. 1980). Sdlg. 78-51. MDB 6" 115 cm) M-L. "S. white, slightly tinged blue; F. light blue (RHS 104D); pale blue beard. 74-46: (Carousel Princess x Gunga Din) X Greenlee GX-11., Willott 1981."

Most miniature dwarf beardeds (MDBs) do quite well in my growing conditions. This northern MN zone 3b climate inflicts severe, extended cold during the winter months, often with little snow cover for insulation. The summer growing season is short with temps that sometimes exceed 90 degrees F. My soil is very heavy, compacted clay with a slightly acid pH, though I grow my irises in well-amended, raised beds or windrows with improved friability and drainage. A large local deer population frequently tramples and sometimes grazes on my irises in early spring and late fall. Iris borers are present but managed successfully with a granular systemic grub control product. Weeds are abundant and only occasionally beaten back by an admittedly lazy gardener (yours truly). Fertilization is inconsistent, when provided at all. Different beds range from full sun to barely 5-6 hrs of sun a day.

ALPINE LAKE is a beautiful little flower, abundant bloomer, and prolific increaser. My flowers, however, tend to color break heavily. I have yet to determine whether the color breaking (which I personally find very attractive) is a result of mosaic virus or simply a reaction to the numerous late freezes to which the MDBs are always subjected in my garden. Regardless, I highly recommend this cultivar.
