'Indian Hills' [(Pioneer) x (Cardinal)] Grant 1935 TB-EM-34'' First Featured by Schriener's in 1937. this is a very lovely velvety dark royal purple. We just recieved this one last summer from Stoney Creek Farm in Pennsylvania.
'Indian Hills' was created by Louisville, Kentucky Dentist: Dr. Henry Lee Grant, who also created the lovely lavender and gold toned iris 'Duet'. Anyone interested in learning more about Grant's irises, should know that Dave's Garden now has ALL of the Grant irises in Plantfiles! you just have to go to Specific Search and do a Hybridizer search for 'Grant' and a complete list will be yours. no other internet sites currently have this list. Only DG!
