Has been very hardy here in zone 5 without any protection. Semi-evergreen, nice foliage. Does not grow good in hot dry conditions and does not like chalky soils. Needs acidic soil or will get leaf chlorosis. I love this Magnolia, even better than Henry Hicks. Nice to have a Magnolia I don't have to treat for Magnolia Scale.

Past its big and long initial bloom of the season there are always a flower or two to provide some fragrance in the yard. The foliage is lustrous and looks almost tropical. This tree is semievergreen here and holds most of its leaves into january when you seem to need it the most then they begin to shed as you cross from mid winter to late winter. A few leaves on the end of branches always remain luckily to last until spring. The fruit cones can be ornamental can as well. After many weeks of ... read more
