Pyramid Magnolia (Magnolia pyramidata)

Description
  • Global Rank: G4 - Apparently Secure
  • Legal Status: N/A
  • Family: Magnoliaceae
  • State: TX, AL, AR, FL, GA, KY, LA, MS, SC
  • Nature Serve ID: 129936
  • Date Inducted in National Collection: 01/01/1985

Magnolia pyramidata, known so for its pyramid shaped crown, is one of the rarest magnolias in North America and has potential for a landscape tree due to its compact crown and beautiful creamy-white flowers. This rare tree first became known in Europe when brought to England by Bartram in 1806 (Harrar and Harrar 1962, Radford et al. 1968, Godfrey 1988, Dir 1998). It closely resembles Magnolia fraseri, but has an overall smaller stature than this more common species, growing only to 3-7 m (10-20 ft) in height . Leaves are also smaller and are of a peculiar shape: "kitelike".

Merkle and Watson-Pauley (1994) found that by transferring germinants directly into potting soil, plantlets were more likely to survive and were considered more vigorous.

Populations need to be identified and monitored. Understanding this species general biology and ecology would be useful in conservation efforts.

M. pyramidata is rarely cultivated because propagation is difficult. No cultivars have been selected or hybrids made.
