COMPACT UPRIGHT NANDINA · BERBERIDACEAE · VIVID RED NEW GROWTH

Nandina domestica ‘Seika’ Obsessed®

Family: Berberidaceae · Pot diameter: 15 cm · Current height: 25 cm

Red new growth
Narrow upright habit
Evergreen seasonal structure
Plantarium Silver 2011

Nandina domestica ‘Seika’ Obsessed® is a compact upright nandina producing vivid red new growth above deeper green older foliage. Numerous fine stems arise from the base and form a narrow clean mass without a heavy woody trunk. As compound leaves mature, the palette moves from red to green and returns to warmer tones in cool weather.

Use it as a narrow vertical colour accent by an entrance, repeated along a path or in a pot where red tips show above lower textures.

Silver award, Plantarium 2011.

What makes it distinctive

Three elements define this exact cultivar’s form and presence.

Red upper growth

Each new flush opens with vivid red pigment above mature foliage.

Many basal axes

The habit is built from separate fine stems rather than one central trunk.

Narrow scale

Upright growth provides colour without occupying a broad area.

Why you will love it: because red upper growth gains a clear presence on a compact narrow upright shrub, without excessive styling.

In the garden & on the terracePlacement & plant combinationsAllow roughly 50–60 cm of width and give sun or light partial shade, retaining space at the base for new stem renewal.

Planting position

Ideal position

Allow roughly 50–60 cm of width and give sun or light partial shade, retaining space at the base for new stem renewal.

Colour & compatibility

Compatible combinations

Pair the red tones with gold, dark or blue-green foliage in plants for sun or light shade and free-draining soil.

Loropetalum chinense ‘Black Pearl’ — deep-purple evergreen foliage makes red tips appear brighter
Carex buchananii — fine copper blades continue the upright movement at a lower level
Hebe ‘Wiri Mist’ — the small blue-green crown provides a cool stable counterweight to the changing nandina

Care at a glance

Light

Sun to light partial shade; good light strengthens red tones without drying the root.

Watering

Maintain even moisture while establishing, then water again when the surface dries.

Climate & resilience

A hardy evergreen shrub; protect container roots from prolonged frost and freezing wind.

Safety

Not edible and contains cyanogenic compounds. Prevent children and animals from chewing leaves or any fruit.

Detailed careComplete care guideLight, watering, soil, feeding, pruning and problem prevention.

Position & light

Sun to light partial shade; good light strengthens red tones without drying the root.

Watering & drainage

Maintain even moisture while establishing, then water again when the surface dries.

Soil & repotting

Free-draining organic soil from slightly acidic to neutral; strong alkalinity can cause chlorosis.

Feeding

Use a small dose of balanced feed in spring; excess loosens the compact habit.

Pruning & habit

Remove old or disproportionately tall stems at the base without shearing the top horizontally. Renew one old stem at the base when needed and do not cut every red tip to a horizontal line.

Problem prevention

Watch for chlorosis in lime-rich soil and root stress when water remains in the saucer.

Development through timeFrom establishment to mature habitFrom first establishment to the exact plant’s natural mature habit.

First season

During the first season it directs energy into root establishment and a few strong new shoots rather than filling its final space immediately.

Establishment

New tips fill gaps in the woody framework and the natural crown becomes denser without changing its basic growth type.

Mature scale

With long-term growth it reaches about 60–75 cm in height and 50–60 cm in width, forming a compact narrow upright shrub.

Mature habit & dimensions

about 3 years

Height 60–75 cmWidth 50–60 cmcompact narrow upright shrub

At maturity it forms a compact narrow upright shrub, about 60–75 cm × 50–60 cm.

Form through time

Seasonal cycle

Evergreen structurecompact narrow upright shrubTwo truthful states

Spring–summerRed young leaflets open at the top of many upright stems.

Autumn–winterThe same narrow crown develops deeper red and copper tones.

Both drawings show the same natural architecture as foliage, flowers and active growth change.

What to expect after planting: The final habit develops gradually; retain the natural framework and assess growth over a complete season.

History & originCultivar originThe documented history of the exact cultivar and the limits of what is known.

‘Seika’ arose as a naturally occurring whole-plant mutation of Nandina domestica ‘Gulf Stream’. April Herring and Adriana Garza found it around July 2005 among young plants in a 72-cell tray in a greenhouse at Magnolia Gardens Nursery, Magnolia, Texas.

The selection was retained for its compact upright habit and deep-red young growth that holds colour for longer, then reproduced asexually by micropropagation at Magnolia Gardens Nursery.

The US plant-patent application was filed on 9 March 2010 and USPP21,891 was granted on 3 May 2011. ‘Seika’ is marketed as Obsessed®, protected in Europe under EU 36059 and received a silver award at Plantarium 2011.

Greenleaf for Plant NerdsScience nobody asked forBotanical detail for anyone who wants to know what lies behind the plant’s appearance

Repeatedly divided compound leaf

The visible unit is a repeatedly divided compound leaf, not a cluster of independent small leaves.

Red protection in young tissue

Anthocyanins can reduce photo-oxidative stress while young chloroplasts mature.

Frequently asked questions

Six practical answers covering position, water, seasonality, pruning, mature scale and safety.

01How much light does it need?

Sun to light partial shade; good light strengthens red tones without drying the root.

02When should it be watered?

Maintain even moisture while establishing, then water again when the surface dries.

03Can it stay permanently in a pot?

Yes, in a container matched to its final scale, with open drainage holes and the upper compost refreshed each spring.

04When and how should it be pruned?

Remove old or disproportionately tall stems at the base without shearing the top horizontally.

05How large does it become?

At maturity it reaches about 60–75 cm high and 50–60 cm wide, with a natural compact narrow upright shrub.

06Is it safe to eat or for pets?

Not edible and contains cyanogenic compounds. Prevent children and animals from chewing leaves or any fruit.
