Dr. Merrill Magnolia

Magnolia x loebneri 'Dr. Merrill'

This plant is not available at this time through Bower & Branch. Bower & Branch provides this information for reference only. Please click here to be placed on a waiting list. See below for other selections.

Dr. Merrill Magnolia’s joyful display of sweet-smelling, bright white flowers comes as a relief, because it can only mean one thing:  spring has arrived!  After a long, cold winter, a Merrill Magnolia in your yard will lift your spirits and put a smile on the face of everyone who passes by.  For maximum impact, plant this medium-sized accent tree in front of dark green evergreens, such as Norway Spruce or Arborvitae.  Our low-branched, multi-stemmed Merrill Magnolias do double-duty as specimens and as dense, leafy privacy screens during the growing season.  Our single-stem Merrills have more of a traditional tree shape, with clearance below for planting early bulbs like daffodils and hyacinths.  Let the springtime begin!

The Story

Dr. Merrill Magnolia is a hybrid of two magnolia species which retains the best qualities of both parents:  it flowers at a young age, and it grows vigorously.  A student at Harvard University made the cross in 1939, but the honors of the naming went instead to Dr. Elmer Merrill, a former director of the arboretum there.  Dr. Merrill possessed a vast knowledge of plants from all over the world; during WWII, he published a survival guide identifying edible and poisonous plants for our troops in the South Pacific.

The Details

Dr. Merrill…paging Dr. Merrill…you need some heart jumping excitement in your garden - stat! This flowering Magnolia will give you a boost with an abundance of fragrant white flowers. Dr. Merrill's crisp white star-like flowers cover the bare branches of this dense, low-branching tree in early spring.

How to Grow

Dr. Merrill isn’t difficult to grow, and is cold-hardy to Maine.  With sunshine and regular water, it will flourish.  The only problem with these early-blooming magnolias (early March in our southernmost states, late April in the North) is that every few years, a late frost zaps the blossoms, turning them the color of toasted marshmallows.  There isn’t much you can do about it.  For many, the glory of the “good years” outweighs the risk of a bad one.  It all depends upon whether you see the glass as half-empty or half-full!
