Obsession™ Nandina

Nandina Obsession (Nandina domestica 'Seika') is not considered invasive, unlike some other varieties of Nandina domestica. One of the key reasons that Obsession Nandina is non-invasive is that it does not produce the abundant clusters of berries commonly associated with older nandina varieties, which are responsible for the spread of the species into natural areas. The lack of significant berry production makes Obsession a safer choice for landscapes, as it does not pose the same ecological risks of spreading and crowding out native plants. As a result, gardeners can enjoy the beauty and vibrant color of Obsession Nandina without the concern of it becoming an invasive issue in the environment.

In many areas, the heavily fruiting varieties of nandina have become problematic because birds spread the seeds, causing the plants to establish in natural habitats where they compete with native species. Obsession Nandina, however, has been bred to focus on its colorful foliage rather than fruit production, significantly reducing its invasiveness. This makes it a great choice for those who want to include nandina in their garden but are concerned about potential impacts on local ecosystems. Obsession Nandina offers the beautiful, year-round color and compact form of traditional nandinas without the invasive tendencies, making it a responsible and attractive choice for both residential and commercial landscapes.

Nandina Obsession has a moderate growth rate, typically adding around 6 to 12 inches per year under optimal growing conditions. This steady growth rate makes Obsession Nandina ideal for gardeners seeking a low-maintenance shrub that will gradually fill in garden beds or borders without overwhelming the landscape. When planted in full sun to partial shade with well-drained, slightly acidic soil, Obsession Nandina will develop into a dense, compact shrub that reaches a mature height and spread of 3 to 4 feet. To encourage healthy growth, be sure to water consistently during the first growing season and apply a balanced, slow-release fertilizer in early spring to support lush foliage development.

The moderate growth rate of Nandina Obsession also means it is easy to control, making it an excellent choice for creating low hedges, foundation plantings, or for use in containers. Its controlled growth ensures that the shrub remains well-behaved, keeping its compact, rounded form without requiring constant pruning or maintenance. Although it may take a few years for Obsession Nandina to reach its full size, the reward is a beautifully colored, evergreen shrub that offers year-round interest with minimal care. Its new red growth in spring and fall contrasts strikingly with the mature green leaves, creating a dynamic and colorful display that enhances any garden space over time.

Yes, you can create a hedge with Nandina Obsession, as its compact size, dense growth, and vibrant year-round color make it an ideal choice for low hedges and borders. Obsession Nandina grows to a height of 3 to 4 feet, with a similar spread, making it perfect for creating a hedge that provides a natural barrier without overwhelming the landscape. The stunning red new growth that turns to dark green adds color and texture, ensuring that the hedge remains attractive throughout the year. To create a successful hedge, space each Obsession Nandina 2 to 3 feet apart, which will allow them to grow into a continuous line while maintaining the compact, bushy form that characterizes this cultivar.

In addition to being visually appealing, Obsession Nandina is a low-maintenance choice for hedges, as it is both drought-tolerant and heat-tolerant once established. Its deer-resistant foliage means the hedge will remain undisturbed in areas prone to deer activity, ensuring that your planting retains its attractive appearance. For best results, plant Obsession Nandina in full sun to partial shade, as this will encourage the richest foliage color and the best overall growth. Prune lightly in late winter or early spring to maintain the desired height and shape of the hedge, removing any dead or damaged branches as needed. With proper care, an Obsession Nandina hedge will provide a colorful, textural backdrop or a defined border that enhances the visual appeal of your garden year-round.

Obsession Nandina has a compact size, reaching a mature height of 3 to 4 feet, which makes it perfectly suited for container gardening. When planting in a pot, choose a container that is at least 12 to 18 inches wide and has good drainage holes to prevent water from sitting at the bottom and causing root rot. Fill the pot with high-quality, well-draining potting soil, and place your Nandina Obsession in a spot that receives full sun to partial shade for the best foliage color and growth.

To keep your potted Nandina Obsession healthy, water it regularly, especially during hot weather when pots tend to dry out more quickly. Make sure the soil remains consistently moist but not waterlogged. Adding a layer of organic mulch around the base of the plant can help retain moisture and keep the roots cool during warmer months. Fertilize in early spring with a balanced, slow-release fertilizer to provide the nutrients needed for lush, vibrant growth. The stunning red new growth and green mature leaves make Obsession Nandina a beautiful focal point in a container, and its drought tolerance and low maintenance needs make it a perfect choice for those who want to add year-round beauty to small spaces without constant upkeep.
