A group of hybrids developed by B. Y. Morrison at Pass Christian, Mississippi following his retirement from the U.S. Dept. of Agriculture. Clones were first introduced in 1964 and registered 1964-65.

The breeding work is largely an extension of work with the Glenn Dale Hybrids based on a continuing interest in late blooming and double flowering clones. 124 flats of seedlings were moved from Maryland to Morrison s home, Back Acres, in Mississippi in 1951. Over 500 crosses were made with 370 numbered clones selected for testing and evaluation. Many of the unnamed numbered clones are still being grown and evaluated by collectors and friends.

Foliage is of heavy texture and tolerant of high air temperatures. The flowers are of equally heavy texture and generally appear in mid to late midseason. The plants with a few exceptions are as cold resistant as the Glenn Dale Hybrids-zone 7a, but the flowers are not as cold resistant.
