The Garden At The Belvedere Centre (3)

Jeremy Bartlett's LET IT GROW blog Posted on by

Since my last update on our work on the garden at The Belvedere Centre (3 April 2012) we have had lots of rain, which has watered in everything we’ve planted.

By a combination of avoiding some of the showers and putting up with getting wet, we’ve done more weeding and tidying and have planted up more of the garden.

The shady border and sunny border are now complete. We’ve added more ferns and other shade loving plants to the shady border (including Epimedium x versicolor ‘Sulphureum'”, Epimedium x warleyense and Beesia calthifolia from Harveys Garden Plants) and mulched the bed with well rotted bark to create as near to a woodland floor as we can.

We’ve done work on the western border, filling gaps between existing shrubs with hardy perennials that were given to us as a donation, and a couple of shrubs: Ribes sanguineum “King Edward VII” (Flowering Currant) and Amelanchier canadensis. Both will have pretty spring flowers and the Amelanchier will provide edible fruit and lovely autumn leaf colour. And now to the centre of the garden. This requires some landscaping work but we’ve made a start by weeding and marking out the line of the paths through the centre of the garden.

Read the next update about the garden.

Red Dead-nettle, Lamium purpureum

Red Dead-nettle

Red Dead-nettle – on the allotment

It is spring and Red Dead-nettles (Lamium purpureum) are nearly everywhere – in gardens, in cracks in the pavement and on the allotment. In a mild spring these pretty flowers can start appearing as early as February and they can continue throughout the spring and summer and into autumn.

To many the Red Dead-nettle (also known as Purple Dead-nettle, Badman, Badman’s Posies, Sweet Archangel or Red Archangel) is a rampant weed and it is certainly good at seeding and producing more of its kind on newly weeded soil and other bare ground. It can also carry cucumber mosaic virus and potato leaf-roll virus. A single plant can produce between one and four thousand seeds and evidence of Red Dead-nettle has been found in Bronze Age deposits, so it probably came to Britain with early agriculture, along with other weeds. It has since spread to North America, where it is listed as an invasive species in some areas.

But Red Dead-nettle flowers are very popular with bumblebees when few other flowers are about so I always allow a few plants to grow on the allotment. I find that on my dry, sandy soil Red Dead-nettles don’t cause much trouble as they can be pulled or hoed out very easily and they are never a nuisance. From May onwards a crop of different summer weeds take over and cause far more trouble: Fat Hen, Lesser Bindweed, Gallant Soldier, sowthistles, to name but a few.

Red dead-nettle is a member of family Lamiaceae, which includes sage, mint, thyme and other useful kitchen herbs. It is also edible and is a pleasant addition to spring salads – use the leaves and flowering tops. The leaves can also be steamed, perhaps with some butter added at the end of cooking. Other recipes include bacon and deadnettle strata and springtime fritters.  I sometimes just nibble some leaves when I’m gardening. Red Dead-nettle is also used in herbal medicine for its possible anti-inflammatory and antimicrobial properties, or for treating wounds.

See the Wildflower Finder website for some lovely photos of Red Dead-nettle, much better than the ones on this page.

Caper Spurge, Euphorbia lathyris

Jeremy Bartlett's LET IT GROW blog Posted on by

When Grapes Hill Community Garden was built the tarmac that originally covered the site was removed and soil was brought in by truck from a depot on the edge of Mousehold Heath in Norwich. Originally, the soil came from the war memorial site outside Norwich’s City Hall.

With the soil came plants, in the form of roots (Hedge Bindweed, Calystegia sepium, which we fortunately removed in late winter 2011) and seeds. The latter included lots of commoner weeds but also some more interesting exotics, such as Milk Thistle (Silybum marianum), Shoo-Fly Plant (Nicandra physalodes) and Caper Spurge (Euphorbia lathyrsis).

I knew that the bold, upright plant with its rigidly arranged leaves with their white midribs was a spurge (Euphorbia) but it was only recently that I confirmed that it was Caper Spurge (Euphorbia lathyris). It is now starting to flower and, as it is a biennial this will be its last year in the garden. We have option of letting it seed but will probably remove it before then to prevent the garden becoming a forest of its seedlings. The seeds (which look like capers but are very poisonous) are released explosively and are also dispersed by ants (reference). We will need to be careful when removing it, as the toxic, milky sap can cause skin irritation and even serious injury if splashed in the eyes.

Caper Spurge is also known as Mole Plant because it allegedly deters moles where it is planted. Another name is Petroleum Plant because it contains high levels of hydrocarbons, and it has been suggested that it could be used as a petrol substitute if enough of the plant was grown.

Medicinally, Caper Spurge was sometimes used as a violent purgative. Beggars sometimes used the leaves to create unsightly skin sores, which would cause passers by to give them more money out of pity. The excellent Plants For A Future Database lists other uses as well, including the treatment of tumours and snake bites.

There are some good pictures of the plant on the Virginia Tech Weed Identification Guide website if you need to identify it. The plant is classed as a naturalised alien in the UK, on roadsides, waste tips and old gardens as well as in open woodland (view UK distribution map). It is sometimes grown in gardens as well.
