How to grow Nandina, common name Heavenly Bamboo

Nandina is one of the best evergreen garden shrubs with all year round interest. It's common names Heavenly or Sacred Bamboo, but it isn't in any way related to a Bamboo. It is safe to grow and not a garden thug or invasive, in fact its appearance it is quite delicate. It is known as Heavenly Bamboo because it has religious associations in China where it is used to decorate alters and it is also very popular in Japan.

I am always surprised that Nandina is not more widely grown as it is a lovely, well-behaved shrub. It makes a great addition to the garden;  it has a lovely light form, delicate  pointed leaves on branches with an arching habit. It looks a little like a bamboo in that the stems are bamboo like in appearance.

One of the best things about growing Heavenly Bamboo is it's all year round colour and interest. When the leaves open they take a red tint, which deepens to a ruby read in the autumn. Nandina like it hot and in a good summer with some heat they will produce white flowers as in the image top left, and profusely if the shrub is in good growing conditions followed by bright red berries as in the centre image. The colourful nature of the shrub is shown in the image far right. Nandina has a lot going for it and not a difficult shrub to grow, despite its delicate appearance. 

One of the real benefits of growing Nandina, the heavenly bamboo, is that when it has lovely autumn colour, it keeps its leaves as an evergreen. So many shrubs which are attractive in the autumn, such as Acers, drop their leaves. Although classified as an evergreen, it may lose some leaves in a cold winter.

Nandina originates from the mountain valleys of Japan, China and India and it is fully hardy to H5. Although fully hardy  Nandina grows best in a sheltered spot away from cold winds and on well-drained soil. Nandina is happy on most soils, which are neither too wet nor too dry, and prefers soil on the acid side.

Nandina are attractive shrubs and I would recommend planting in an area with some space around it to enable the shrub to stand out.  I have one growing alongside a couple of other shrubs and I rather regret it as the Nandina gets overshadowed. If I was planting again, or planting another, I would give it more space to be admired. 

It is a low maintenance shrub which does not require feeding or pruning. If it does become overgrown, it should be pruned in April or May, or after flowering.

Be aware the berries are toxic to cats, although safe and loved by birds.

There is quite some variance in the Nandinas commonly offered for sale from large shrubs to compact small shrubs. 

One of the most popular varieties to grow is Nandina domestica 'Fire power' which as the name suggests has strong autumn/winter colour and a largish shrub which will reach 1.5m . To get berries the shrub needs a good amount of sun and warmth and so performs better during good summers.

Not all Nandina produce berries, some N. domestica varieties do, and in particular 'Richmond' which has the AGM reputedly for more reliably producing berries and grows to around 2m. N.'Fire Power' is widely grown in the UK which has good colour but not so good on the berry front.

There are also varieties where the foliage colour tends to be more bronzed than red such as N. 'Seika'  a compact variety growing up to .6m and which needs winter protection and 'Sunset' with purple tinges to the foliage. There are smaller varieties suitable for growing in containers such as 'Tuscan Flame' which grows to around 35 cms.
