(Camera Canon EOS 550D - Sheffield, Ballito, KwaZulu Natal, South Africa)

The Natal Wild Banana (Strelitzia nicolai) grows up to 12m high and 4m wide. It is an evergreen tree with multi-stems that form dense clumps.

The stem is woody and smooth in texture. It is light to dark grey and marked with old leaf scars. Attached to the stem by long, thick leaf stalks are the enormous, opposite leaves that are shiny and grey-green, with blades capable of reaching up to 2m in length. These tear in the wind and come to resemble giant feathers.

The inflorescence is composed of a dark blue bract, white sepals and a bluish-purple "tongue". The entire flower can be as much as 18 cm (7.1 in) high by 45 cm (18 in) long and is typically held just above the point where the leaf fan emerges from the stem. Flowers are followed by triangular seed capsules.

The flower of the Natal Wild Banana is a typical Crane Flower inflorescence, up to 500 mm long. The flowers of this tree have white sepals with blue petals and consist of 5 purplish blue, boat-shape sheaths.The whole flower resembles the head of the bird, with a white crest and purple beak. The tree flowers throughout the year with a peak in spring-summer. The inflorescence is compound (more than one flower).

The seeds are black in colour, with a tuft of a bright orange woolly aril on the lobe. They are produced mostly in autumn and winter, March to July. The easiest way to propagate this tree is from root suckers, but it will also grow from seed.

Restricted to evergreen coastal forest and thicket of eastern South Africa from the Great Fish River northwards to Richards Bay. It is also considered native to Mozambique, Botswana and Zimbabwe, and is reportedly naturalized in eastern Mexico.

Strelitzia Nicolai is among the few plants which have been verified to contain the pigment bilirubin, which is usually found in animals.

Tool tip

Properly maintained quality garden tools are a joy to use and can last for generations. And, like most things, an ounce of prevention is worth a pound of cure. Regularly cleaning and oiling your garden tools will prevent rust, keep them sharper, and allow the handles to stay strong. Start by giving your tools a good scrubbing to remove any mud and grit from the blades and handles. Dry with old towels, then set them aside overnight so they dry completely to avoid trapping moisture. Using a clean rag, apply lubricating oil to both the wooden handle and the metal blade. Rub the oil into the surface then wipe off any excess. The oil will help prevent rust and condition the wood to keep it from absorbing water and prevent cracking. After the handle has dried, apply a second coat of oil to the wood if needed. Tools with fiberglass or composite handles will only need a good cleaning.

Wildlife Tips

PUT UP AN OWL BOX : Owls aren't common garden visitors for most, but if you know they are around, it's worth providing extra nesting sites. General Owl boxes are bigger than ordinary bird boxes. They're shaped according to the needs of the species. Barn owl boxes are large and square, or sometimes triangular, with a ledge outside the entrance for young owls to stand on. Barn owls like to nest in a solitary tree on the edge of woodland, between 3 and 5m above the ground. Keep out cold drafts by facing all owl boxes away from prevailing winds. It also makes it easier for parents to fly to the entrance. If you fix the owl box to a tree, use a strap to keep it in place so you don’t damage the trunk. As with all nest boxes, do not disturb the box for cleaning until you are sure that the young have left. Tawny owls in particular can be aggressive when protecting their young. Don’t be disappointed if your box stays empty for the first year. Birds often choose a nesting site during the autumn, winter or early spring. Leave the box where it is for the winter and it could be a nice dry place for birds to roost when the weather’s bad. Please do not unnecessarily disturb the birds and never remove any eggs from the nest.

Leave those leaves! I know many gardeners don't like the 'messy' look of fallen leaves, but they have a lot of benefit to wildlife and your garden. Many wildlife species live in or rely on the leaf layer to find food and other habitat, including toads, shrews, earthworms and many insect species. From a gardening perspective, fallen leaves offer a double benefit. Leaves form a natural mulch that helps suppress weeds and at the same time fertilize the soil as they break down. Why spend money on mulch and fertilizer when you can make your own?

More about me

I've been gardening ever since a child, when I spent time with my father in his vegetable garden. But my fascination with Echeverias started in the 1980's, when my father gave me a pot with five Echeverias, which turned out to be E. imbricata. At first I wasn't much interested in them and planted them in some obscure corner of the garden and completely forgot about them. How great was my surprise when, a couple of months later, I noticed that they had spread and made a beautiful display - I was hooked!

It is utterly forbidden to be half-hearted about gardening. You have got to love your garden whether you like it or not.
