Gardeners' Notes:

Positive pollyk On May 19, 2009, pollyk from Hannibal, NY (Zone 6a) wrote:

The real Imperial Magic is a beautiful iris. The picture from Lilypon courtesy Ensata Gardens is the real thing.

Unfortunately, this is one of the JIs that has become mixed up in commerce due to Dutch growers buying cast off seedlings from Japan, and giving them names like Pink Beauty, Imperial Magic, etc. Many of the Imperial Magic from some of the large retail stores are plain purple, or speckled purple, and these are not Imperial Magic.

Do not trade these as Imperial Magic unless they match the picture of the one from Ensata. Buy from true iris growers, and they will be true to name.

Here is the registered description of Imperial Magic from the Society For Japanese Iris:
"IMPERIAL MAGIC Marx, Louise Reg. 1960 60-11 45in 114cm E 3 S. deep lilac, edged white; F. white, soft purple veins; violet styles. From two Marhigh sdlgs. Marx Gardens 1961 Available "
