Betty Magnolia and Other Little Girl Magnolia Varieties Compared

Choosing a magnolia for a small space means exploring the Little Girl series, a collection of compact hybrid cultivars bred at the U.S. National Arboretum. These shrubs combine hardiness with spectacular spring color, but each variety has distinct traits. If you're torn between Betty Magnolia and its siblings in the series, this guide breaks down what sets each one apart and which fits your garden.

Understanding the Little Girl Magnolia Series

The Little Girl series consists of eight hybrid cultivars, each crossed from Magnolia liliiflora (native to China) and Magnolia stellata (native to Japan). The program at the National Arboretum in Washington, D.C. aimed to produce compact, hardy magnolias with reliable bloom and cold tolerance. All eight cultivars share common traits: they're deciduous shrubs suitable for USDA zones 4 through 8, they bloom in mid-to-late spring, and they remain small enough for residential landscapes. Beyond that, they diverge in bloom color, exact size, and growth habit.

The series includes Betty, Ann, Jane, Judy, Pinkie, Randy, Ricki, and Susan. Betty is one of the earlier releases and remains among the most widely available in nurseries.

Betty Magnolia: The Specifications

Betty Magnolia (Magnolia 'Betty') matures to 10 to 15 feet tall and 8 to 15 feet wide, with a slow to moderate growth rate of roughly 6 to 12 inches per year. The plant reaches blooming age within 3 to 5 years of planting and lives 50 to 100 years with good care.

Bloom time is one of Betty's defining features. The flowers appear in mid-to-late spring, which means buds face less risk from late frosts compared to earlier-blooming magnolias like star magnolia and saucer magnolia. The blooms themselves are distinctive: reddish-purple to wine-red on the outside, white to pale pink on the inside. They release a light, sweet fragrance. The plant may produce sporadic rebloom in summer under favorable conditions.

Betty prefers full sun to part shade, with best flowering in full sun. It grows in moist, well-drained, organically rich soil and tolerates clay if drainage is adequate. The plant prefers acidic to neutral soil (roughly 5.0 to 6.5 pH) and can develop chlorosis in very alkaline conditions. Once established, it has low to moderate drought tolerance and poor salt tolerance.

Other Little Girl Varieties at a Glance

While all eight cultivars share the same parent species and general hardiness range, they differ in bloom presentation and mature size.

Magnolia 'Ann' produces deep red or reddish-purple flowers and tends toward a more compact form than some of its siblings. It is frequently compared to Betty and is one of the most commonly confused pairings in this series.

Magnolia 'Jane' features purple flowers and is another cultivar often seen alongside Betty in garden centers. Like Ann, Jane is compact and widely available.

Magnolia 'Susan' produces flowers that are typically pink or rose-tinted and blooms later in the spring season.

Magnolia 'Judy', 'Pinkie', 'Randy', and 'Ricki' round out the remaining cultivars, each with its own distinct bloom color and growth tendency. Check with your local nursery or extension service for their specific sizes and bloom characteristics in your region, as these details can vary based on growing conditions and climate.

Betty Magnolia vs. Ann Magnolia: The Key Differences

Betty and Ann are the pair most often confused at nurseries. Both have deep red exterior flowers, both are hardy to zone 4, and both grow to similar sizes. The main distinction lies in their precise bloom color and slightly different growth habits.

Betty blooms with reddish-purple to wine-red petals on the outside and white to pale pink on the inside, creating a two-tone effect. Ann's flowers are typically deeper red throughout. Some gardeners report that Ann tends to maintain a slightly tighter, more columnar habit than Betty, though this is subtle and depends on growing conditions and pruning.

If you stand blooms from both side by side, Ann appears more uniformly red, while Betty shows more dramatic color contrast. For a gardener who loves a strong red statement, Ann may be the pick. For one who prefers the softer pink-and-red combination, Betty wins.

Bloom Time, Color, and Size Comparison

Cultivar	Bloom Color	Mature Height	Mature Width	Growth Rate	Best Feature
Betty	Reddish-purple exterior, white-to-pale-pink interior	10-15 ft	8-15 ft	6-12 in/year	Later bloom reduces frost damage; two-tone flowers
Ann	Deep red throughout	Compact	Compact	Slow to moderate	Uniformly deep red blooms; dense habit
Jane	Purple	Compact	Compact	Slow to moderate	Purple tone; widely available
Susan	Pink to rose	Compact	Compact	Slow to moderate	Latest bloom timing; softer pink color
Judy, Pinkie, Randy, Ricki	Varies (pink, red, magenta tones)	Compact to small	Compact to small	Slow to moderate	Variety of color options; specialty cultivars

Note: Specific mature heights and widths for cultivars other than Betty may vary by region and growing conditions. Check with your local extension service or nursery for details on the variety you're considering.

Pros and Cons: Betty Magnolia vs. the Rest

Betty Magnolia

Pros:

• Mid-to-late spring bloom reduces frost damage to flower buds
• Two-tone flower color (wine-red outside, pale pink inside) adds visual interest
• Tolerates zones 4 through 8, including cold climates
• Moderate growth rate (6 to 12 inches per year) allows for planning and pruning
• Widely available at nurseries
• May produce sporadic summer rebloom

Cons:

• Larger (10 to 15 feet tall) than some compact Little Girl varieties
• Prefers acidic to neutral soil; can develop chlorosis in alkaline soil
• Low to moderate drought tolerance requires regular water until established
• Two-tone blooms may be less dramatic than solid deep-red or vivid pink options

Ann Magnolia

Pros:

• Deeper, more uniform red blooms
• Tends toward a very compact form, ideal for tight spaces
• Cold hardy; same zone range as Betty
• Lower maintenance due to dense growth habit

Cons:

• Earlier bloom timing means higher frost risk in cold climates
• Less widely available than Betty in some regions

Susan Magnolia

Pros:

• Later bloom timing offers maximum frost protection
• Pink-to-rose color is softer and distinctive
• Very compact size suits small gardens

Cons:

• Less common; may be harder to source
• Smallest of the series, limiting landscape presence

Which Little Girl Magnolia is Right for You?

Choose Betty Magnolia if:

• You want reliable, mid-to-late spring blooms with less frost risk
• You prefer a plant that reaches 10 to 15 feet and creates a visible focal point
• You like the contrast of reddish-purple and pale pink flowers
• You live in zones 4 through 8 and want a proven performer
• You want easy availability and nursery selection

Choose Ann Magnolia if:

• You prefer deep, solid red blooms
• You have a very small space and need maximum compactness
• You accept earlier bloom timing and late-frost risk as a trade-off for darker color

Choose Susan or other specialized cultivars if:

• You want the absolute latest bloom timing for maximum frost protection
• You prefer pink or rose tones over red or purple
• You're willing to hunt for specialty nurseries or mail-order sources
• You're building a collection and want variety within the Little Girl series

Soil, Hardiness, and Care Across the Series

All Little Girl magnolias thrive in moist, well-drained, organically rich soil. They prefer acidic to neutral pH (roughly 5.0 to 6.5) and may show chlorosis in very alkaline conditions. Full sun produces the most reliable blooming, though all tolerate part shade.

Once established, they need moderate water and benefit from a light annual feeding in early spring with a balanced or acid-forming fertilizer. Pruning is minimal. If shaping is needed, do it immediately after flowering since buds for next year set soon after bloom.
