Louisa's Song

(Blyth 99 Aust) EM 42"

One of the loveliest tall bearded Iris that we have raised. Standards are lilac-orchid. Falls are red-lavender to orchid-lavender with 1/4in blended lilac edge. Beards are bright tangerine. Huge blooms with lace and ruffles galore. Fine branching with at least four flowering points. Superb parent with many varieties registered from its seedlings.
