Magnolia (Magnolia 'Randy')
Magnolia 'Randy' is a late-blooming, reddish-purple flowering deciduous shrub hardy in zones 4-8.
Complete Plant Information
Overview
Magnolia ‘Randy’ is a prized cultivar, part of the celebrated Little Girl series of hybrid magnolias developed at the National Arboretum. Its primary appeal lies in its reliable spring color, featuring star-shaped, reddish-purple flowers that bloom later than many other early spring bloomers, significantly reducing the risk of frost damage. This slow-growing, multi-stemmed beauty provides excellent structure and a fragrant display, establishing itself as a focal point in the landscape.
As a deciduous shrub or small tree, Magnolia ‘Randy’ offers substantial visual interest from its bloom time in April to May through to its attractive fall foliage coloration. Gardeners value this specific Magnolia for its manageable size, reaching 10 to 15 feet tall, making it suitable for smaller gardens where larger Magnolia species might overwhelm the space. Proper siting is key to ensuring this Magnolia thrives for years as a stunning specimen.
The flowers of Magnolia ‘Randy’ are both showy and fragrant, marking a clear highlight in the early season landscape. Its eventual form is broadly round, offering dense coverage excellent for screening or as an informal hedge. Selecting a cultivar known for reliable performance, like Magnolia ‘Randy’, brings a touch of drama and timeless elegance to any garden design needing a substantial, colorful feature.

How to Grow
For optimal establishment, plant Magnolia ‘Randy’ in the spring or fall when temperatures are cooler. Select a location carefully, as this Magnolia has a fleshy root system that is easily damaged during transplanting; once sited, it prefers to be left undisturbed. The soil should be organically rich, neutral to slightly acidic, medium in moisture, and well-drained.
Consistent moisture is vital, especially during the establishment period; aim for medium watering. Apply a root-zone mulch to help retain this necessary soil moisture and regulate soil temperature. It is highly recommended to site your Magnolia ‘Randy’ where it is protected from harsh winds, and crucially, avoid warm southern exposures which can trick the buds into opening prematurely, making them susceptible to spring frosts.
Pruning for Magnolia ‘Randy’ should be kept minimal; generally, only remove dead or damaged branches. Perform any necessary pruning immediately after the main flowering period concludes in late spring. Because this hybrid blooms later than many others, it is naturally more resilient against late spring freezes, but avoid heavy summer pruning that could encourage tender new growth before winter.
Landscape Uses
Magnolia ‘Randy’ excels as a beautiful specimen flowering shrub, providing a vibrant focal point on lawns or near entryways. Its multi-stemmed, broadly round habit also makes it an effective choice for informal hedges or as a screen near property lines where a taller, flowering barrier is desired. Consider planting it near foundations, ensuring enough space for its 8- to 12-foot spread to develop naturally.
When considering companion plants, pair Magnolia ‘Randy’ with acid-loving evergreens like Rhododendrons or Azaleas, which share similar soil preferences but offer foliage contrast when the Magnolia is bare. For underplanting beneath its canopy, use shade-tolerant perennials that do not require aggressive root disturbance, keeping in mind the shallow roots of the Magnolia. As a standout flowering tree, it deserves a spot where its mid-spring reddish-purple blooms can be appreciated up close.

Noteworthy Characteristics
The Magnolia genus encompasses about 100 species of deciduous or evergreen trees and shrubs, often recognized for large leaves and prominent flowers. Magnolia ‘Randy’ specifically is a cross between M. Liliiflora ‘Nigra’ and M. Stellata ‘Rosea’, part of the Little Girl series bred for late blooming. Its star-shaped, reddish-purple flowers, sometimes showing pink-white tones inside, bloom just before the leaves emerge, and sporadic reblooming may occur mid-summer.

Potential Problems
Potential issues for this Magnolia primarily involve fungal diseases and common garden pests. Fungal diseases gardeners might encounter include leaf spots, anthracnose, canker, dieback, and powdery mildew, often encouraged by overly humid conditions or poor air circulation. To manage these, ensure good air movement throughout the shrub and maintain consistent cultural practices regarding soil moisture.
Insect pests such as weevils, snails, scale, and thrips can sometimes plague the foliage or developing buds of Magnolia ‘Randy’. Routine scouting, especially during the growing season, allows for early intervention. Healthy plants in correctly sited locations are naturally more resilient to pest or disease outbreaks.

Companion Planting
When selecting companions for Magnolia ‘Randy’, prioritizing plants with similar soil acidity and moisture needs is crucial. Acid-loving shrubs like Camellias or Azaleas thrive alongside magnolias, providing evergreen structure during the winter months when the deciduous shrub is bare. These plants also enjoy the well-drained, slightly acidic soil preferred by the Magnolia.
Consider deciduous natives for mid-layer planting that benefit from afternoon shade offered by the developing canopy of the Magnolia. Hostas or Astilbes work well as groundcovers, provided you keep mulch deep around the Magnolia’s root zone to prevent competition and root disturbance. This layered approach helps create a cohesive woodland garden aesthetic.
Seasonal Care Calendar
Gardeners should note that the growing season for this Magnolia requires specific attention to watering and clean-up. In late spring immediately following the bloom, apply any necessary maintenance pruning, removing only spent or damaged wood, as hard pruning can reduce next year’s flower buds. Apply a substantial layer of organic mulch across the root zone to stabilize soil temperatures and retain medium moisture levels.
During the heat of summer, monitor water needs closely; although adaptable, a medium watering schedule means deep, infrequent waterings are better than light daily sprinkles, especially in full sun exposures. Fall foliage turns yellow to bronze-copper, offering late-season color interest before the plant enters dormancy. Minimal winter preparation is needed outside of ensuring the plant is well-hydrated before the ground freezes solid.
