Plum Passion Nandina

Basic Information

Common Name: Plum Passion Nandina

Scientific Name: Nandina domestica ‘Plum Passion’

Native Habitat: Japan, China, and Korea (for Nandina domestica species)

History / Discovery / Cultivator

Nandina domestica, commonly known as heavenly bamboo, is a popular ornamental plant native to eastern Asia. While the species itself has been cultivated for centuries in Asia, particularly in Japan and China where it holds cultural significance, the ‘Plum Passion’ cultivar is a more recent introduction. The exact origins and cultivator of ‘Plum Passion’ are not widely documented in readily available sources. It is likely a selection from a nursery specializing in Nandina varieties, bred for its intense foliage color and compact growth habit.

The Nandina genus belongs to the Berberidaceae family. In its native range, Nandina domestica thrives in woodlands and along stream banks, often found growing in shaded or partially shaded environments. The plant’s introduction to western gardens began in the early 19th century, and it quickly gained popularity for its attractive foliage, berries, and adaptability to various growing conditions. Over time, breeders have developed numerous cultivars, each with unique characteristics, such as different leaf colors, plant sizes, and fruiting habits.

‘Plum Passion’ distinguishes itself from the standard Nandina domestica with its vibrant plum-colored new growth. This characteristic color is most pronounced during the cooler months of the year, adding a splash of color to winter landscapes. The intensity of the plum color depends on factors such as sunlight exposure, temperature, and soil conditions. In warmer months, the foliage may transition to a more greenish hue, but the new growth typically retains some degree of plum coloration.

The ‘Plum Passion’ cultivar offers gardeners a compact and colorful alternative to the traditional Nandina domestica. Its smaller size makes it well-suited for containers, small gardens, and foundation plantings. Furthermore, its vibrant foliage adds visual interest throughout the year, making it a valuable addition to any landscape design. While the specific details surrounding its creation remain somewhat elusive, ‘Plum Passion’ has undoubtedly earned its place as a favored Nandina cultivar among gardening enthusiasts due to its unique characteristics and ornamental appeal. The selection process for this cultivar likely involved careful observation and propagation of plants exhibiting the desired plum-colored foliage, followed by rigorous testing to ensure its stability and adaptability. The enduring popularity of ‘Plum Passion’ stands as a testament to the skill and dedication of plant breeders in creating new and improved varieties of beloved garden plants.

Plant Care Summary

Botanical Insights

Adaptations

Nandina domestica ‘Plum Passion’ showcases several adaptations that contribute to its survival and appeal. Its evergreen foliage allows it to photosynthesize year-round in suitable climates. The plant’s tolerance for both sun and partial shade enables it to thrive in a range of light conditions. Its compact size makes it suitable for various garden settings, including small spaces and containers. The ‘Plum Passion’ cultivar’s vibrant foliage color, particularly the plum hues, are thought to provide some level of protection against intense sunlight due to the increased concentration of protective pigments like anthocyanins. These anthocyanins also act as antioxidants, helping the plant to cope with environmental stresses such as pollution and drought. Its drought tolerance, once established, makes it relatively low-maintenance in appropriate climates. The bright red berries, while toxic, serve as a visual attraction for birds, aiding in seed dispersal in the wild species, though ‘Plum Passion’ is often propagated vegetatively to maintain its characteristics.

Propagation Methods

The most common and effective propagation methods for Nandina domestica ‘Plum Passion’ include:

* Stem Cuttings: Take semi-hardwood cuttings in late spring or early summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix. Keep the soil moist and provide indirect light until roots develop.
* Division: Mature plants can be divided in early spring or late fall. Carefully dig up the plant and separate the root ball into smaller sections, each with its own stems and roots. Replant the divisions in prepared soil.

Toxicology

Nandina domestica ‘Plum Passion’ contains cyanogenic glycosides, primarily in its berries and leaves. Ingestion of these plant parts can be toxic to humans and pets, including cats and dogs. The severity of the reaction depends on the amount ingested. Symptoms in humans may include nausea, vomiting, diarrhea, abdominal pain, and difficulty breathing. In pets, symptoms are similar and may also include lethargy, loss of appetite, and incoordination. If ingestion is suspected, immediate veterinary or medical attention should be sought. Keep this plant out of reach of children and pets, or consider planting it in areas where access is restricted.

Common Problems

Pests:

* Spider mites
* Scale
* Aphids

Diseases:

* Leaf spot
* Root rot (in poorly draining soil)

Other:

* Leaf scorch: Can occur in hot, sunny locations, especially with insufficient watering.
* Poor color development: Insufficient sunlight can result in less vibrant plum foliage.
* Berry production: ‘Plum Passion’ may produce fewer berries than other Nandina varieties.

Rarity & Value

Rarity:

‘Plum Passion’ Nandina is not considered particularly rare, as it is widely available in nurseries and garden centers. However, some variegated or unique specimens exhibiting unusual growth habits or exceptionally intense coloration might command a higher price. The plant’s availability can fluctuate based on seasonal demand and nursery propagation efforts. Certain regional shortages can temporarily increase its perceived rarity.

Value:

The value of a ‘Plum Passion’ Nandina specimen is influenced by several factors. A larger, more mature plant will typically be more valuable than a smaller, younger one. The intensity and uniformity of the plum foliage color are crucial; plants with vibrant, consistent coloration command higher prices. The overall health and vigor of the plant are also important considerations. Container-grown specimens may be priced differently than those grown in the ground. Current market trends and consumer demand also play a role, with popularity increasing during specific seasons or landscaping trends. Finally, plants from reputable nurseries or those with a proven track record of quality may command a premium.
