Overview of the Ann Magnolia

The Ann magnolia (Magnolia x ‘Ann’) is a deciduous hybrid between the lily magnolia (M. liliflora) and purple star magnolia (M. stellata ‘Rosea’). It was bred by the U.S. National Arboretum in the mid-1950s to combine the best traits of its parents.

This magnolia is named after Ann Kosar, who registered the cultivar It’s known for its incredibly showy reddish-purple blooms that open in early to mid spring The flowers resemble tulips, with six petal-like tepals arranged in a cup shape. They emerge a soft rosy pink then darken as they mature.

Ann magnolias are hardy in USDA zones 4-8. When full grown, they reach heights of 8-10 feet tall and spread 8-10 feet wide. Their oval leaves emerge with a bronze tinge then turn green. In fall, the foliage transitions to golden yellow.

The Allure of a Full Grown Specimen

While Ann magnolias are beautiful at any age, a full grown, mature tree in peak bloom is a spectacular sight. Here are some of the standout features of these trees at maturity:

  • Abundant floral display – A mature Ann magnolia can produce hundreds of vivid reddish-purple blooms that blanket the bare branches in spring. Few flowering trees can match this colorful floral show

  • Powerful fragrance – The cup-shaped blooms have a strong, spicy scent that perfumes the air. On a warm spring day, the fragrance carries on the breeze.

  • Greater hardiness – As Ann magnolias mature, they gain cold hardiness and can better tolerate freezing temperatures. Full grown trees flower reliably even after spring frosts.

  • Added ornamental interest – Mature Ann magnolias have character and form that enhance their beauty. The picturesque branching structure and furrowed gray bark also provide winter interest.

  • Minimal care – Once established, these magnolias are low maintenance and quite trouble free. They require little pruning or upkeep to continue thriving.

Ideal Growing Conditions

Ann magnolias are adaptable and relatively easy to grow. Here are their recommended growing conditions:

  • Sun exposure – Full sun to partial shade. Morning sun is ideal for the most prolific flowering.

  • Soil – Moist, well-draining loamy soil is best. But Ann magnolias tolerate a range of soil types including sandy, clay, acidic, and alkaline soils.

  • Climate – Hardy in zones 4-8. Prefers humid climates but tolerates drier areas if supplemental water is provided.

  • Watering – Requires regular watering when young. Mature trees are moderately drought tolerant once established.

  • Pruning – Only requires occasional pruning to shape or remove dead branches. Avoid heavy pruning which can reduce flowering.

When provided with proper growing conditions and care, Ann magnolias will flourish for decades. Their hardy nature and ornamental qualities make them ideal specimen trees.

  • Select a planting spot with full sun to partial shade and well-draining soil.

  • Dig a hole 2-3 times wider than the root ball but no deeper. The top of the root flare should be level with the soil surface.

  • Score the root ball sides and loosen any tangled roots before placing in the hole.

  • Backfill with native soil, tamp down gently, and water thoroughly.

  • Mulch around the base, leaving a 3-4 inch gap near the trunk. Avoid volcano mulching.

  • Stake the tree initially if needed to prevent wind tipping of top-heavy young trees.

  • Water weekly the first year and provide regular deep watering during dry periods.
