Louisa Crabapple

Malus 'Louisa'

The Story

Plant Bio

Crabapple trees are small to medium-sized deciduous trees, highly valued in landscaping for their spectacular spring flower display, attractive form, and often colorful, persistent autumn fruit.

'Louisa' is a beautiful weeping crabapple, forming a graceful, umbrella-like canopy with branches that cascade to the ground. It features true pink blossoms in spring followed by small, persistent, golden-yellow fruit that birds love.

Uses & Benefits:

Its strongly weeping form creates a stunning, year-round architectural feature. In spring, it is completely enveloped in pink blossoms, followed by attractive foliage and then bright yellow fruit that persists into early winter, providing multiple seasons of beauty.

The small stature and graceful habit make it an ideal tree for smaller landscapes, courtyards, or as a focal point in a garden bed where a larger tree would be overwhelming.

The spring blossoms are an important early-season pollen and nectar source for bees and other pollinators. The small, persistent fruits provide a vital food source for songbirds like cedar waxwings and robins in the fall and winter.

Planting

How to Grow

Plant in a location with full sun for best flowering and fruiting
Choose well-drained, loamy soil with a slightly acidic pH
Dig a hole two to three times wider than the root ball
Set the tree so the top of the root ball is level with the ground
Backfill with soil, water thoroughly to remove air pockets
Apply a 2-3 inch layer of mulch around the base

Pro Tip

Avoid pruning the tips of the weeping branches to allow them to cascade naturally; only remove branches that are out of place or crossing.
