Q. Who is Mr. Smarty Plants?

Answered by: Nan Hampton

QUESTION:

I bought a magnolia "ann". Will it hurt my horses to eat any part of it?

ANSWER:

According the U. S. National Arboretum, Magnolia 'Ann' is a hybrid of Magnolia liliflora 'Nigra' x Magnolia stellata 'Rosea'.  M. liliflora is a native of China and M. stellata is a native of Japan.
