Nandina 'Seika' is a low-maintenance architectural shrub with attractive colour-changing foliage.
Despite its common name, Nandina isn't related to bamboo - this non-invasive alternative does have similar, delicate bamboo-like foliage but remains compact and produces the most wonderful red young leaves in spring. This low-maintenance evergreen shrub provides colour and structure to a sunny spot all year round, with foliage emerging bright red in spring and slowly changing to green during summer, before developing a purplish hue for autumn and winter. Attractive clusters of white flowers appear during the summer for added interest. This reliable variety has a neat, bushy shape and is perfectly well suited to growing in patio containers or mixed borders where it will provide a long season of fuss-free colour. Nandina 'Seika' makes a great backdrop for flowering plants, but looks just as flashy as a feature in its own right.
Whether you have a large garden or just a small terraced space, this neat little plant is a great way to inject a long season of colour.

Nandina domestica prefers a sheltered position to an exposed or windy site. It needs a sunny location, close to a south or west-facing wall would provide the perfect conditions.
This variety thrives in most soils, but prefers a rich soil which retains a bit of moisture. To improve your growing conditions, you can mix a good dose of compost into the planting hole prior to planting. If planting in a container, use a heavier soil-based compost rather than multipurpose.
Water regularly during its first season to help it to anchor itself into the soil. Once established in a border, it can usually source water from the soil itself. Shrubs planted in containers require regular watering during the summer months, particularly frequently when the weather is hot.
To improve the overall health of your plant, feed it occasionally during spring and summer with an all-purpose liquid feed, especially if it's planted in a pot where nutrients can quickly diminish.
Lightly clip this shrub to shape after flowering in summer. This is a fairly compact shrub so shouldn't get out of hand, but a yearly trim will help keep it bushy.
