Say hello to one of the most spellbinding magnolias you've probably never heard of—Aashild Kalleberg Magnolia. A rare hybrid of M. hypoleuca and M. sieboldii, this small deciduous tree pulls off an exceptional garden performance with ease. During early to midsummer, its large, egg-shaped flower buds open to reveal intoxicatingly fragrant, creamy white blooms up to 10 inches wide—with bold crimson-purple stamens at the heart. Imagine a peeled egg in an eggcup, then give it perfume and petals.

Its massive paddle-like foliage only adds to the drama. With leaves reaching up to 17 inches long, the tree boasts a broad, tropical flair that feels exotic yet grounded in a hardy package. Despite its grandeur, Aashild Kalleberg Magnolia is refreshingly low-maintenance. Deer leave it alone, pests rarely bother it, and it performs well in dappled sun or morning sun with afternoon shade. Whether you prune it into a formal tree or let it grow as a multi-stemmed specimen, it always steals the show.

Rated to be cold hardy in USDA Zones 5–9 and adaptable to many soil types (as long as they're well-draining), this magnolia doesn't ask for much—just a bit of admiration and some summer space to shine. If you're seeking a rare, sweetly-scented ornamental tree that combines tropical looks with northern toughness, Aashild Kalleberg Magnolia belongs in your garden story.

AASHILD KALLEBERG MAGNOLIA Homeowner Growing & Maintenance Tips

  • Recommended Soil:
    • Prefers rich, humus-rich, well-drained soils.
    • Tolerates loam, sandy loam, and light clay when not waterlogged.
    • Mulch annually to preserve moisture and enrich the soil.

  • Sun Exposure:
    • Thrives in full sun to part shade.
    • Morning sun is ideal with filtered or dappled afternoon light, especially in hot summer zones.
    • Too much afternoon sun can scorch the large leaves.

  • Irrigation Needs:
    • Moderate to regular watering, especially in the first 2–3 years.
    • Keep soil evenly moist during dry spells.
    • Deep watering encourages a strong root system.

  • Feeding & Nutrients:
    • Feed in early spring with a slow-release balanced fertilizer.
    • Organic compost or leaf mold makes an excellent soil amendment.
    • Avoid over-fertilizing, which can reduce flowering.

  • Pruning & Maintenance:
    • Little pruning is needed beyond shaping or removing suckers at the base.
    • Can be trained into a multi-stem shrub or a single-stem tree form.
    • Best pruned right after flowering if needed — avoid pruning in late fall or winter.

Interesting Notes About AASHILD KALLEBERG MAGNOLIA

  • Egg-cellent Blooms: The flower buds famously resemble peeled eggs in an eggcup — a playful nod to its Oyama Magnolia parent, Magnolia sieboldii.
  • Fragrance First: Among the most fragrant magnolias in cultivation, its blooms release a sweet, citrusy perfume that drifts through summer air.
  • Scandinavian Roots: This special hybrid was introduced by Norwegian plantsman Olav Kalleberg, and named for his wife — making it a true labor of love.
  • Leaf It to Me: Leaves up to 17 inches long give this tree a bold, tropical texture rarely seen in temperate gardens — excellent for contrast.
  • Summer's Encore: Unlike most magnolias that bloom in spring, 'Aashild Kalleberg' opens its showy blossoms in early summer and sometimes repeats in late summer.
