Painting Root Vegetables....and Growing the Leaves! The Turnip

Want to paint vegetables but found that you can't buy them with leaves?
The simple answer to this problem is to grow your own!.... but if you don't have the space or time, don't forget that it's actually very easy to grow leaves on root vegetables.....remember growing carrot tops at school?  I've been amusing some of my students with this particular experiment over the last few weeks ....and it's catching on!

You can simply place a root vegetable over water and it will grow some new decent looking leaves in just a few weeks. Beetroot works pretty well! I planted it outdoors and it has some nice leaves, next came the turnip and now I'm onto the radish! To be fair they're not quite as good as the original leaves but still make for a more interesting vegetable painting than a poor old storage organ with no leaves.

One of my most recent efforts is the humble turnip, Brassica rapa subsp. rapa. I started growing the leaves about 7 weeks ago and it's now about to flower and go to seed. There's also the added bonus of beautiful roots!
Here's the painting process in a video ( about 5 mins long) 

How does this work?...very simple biology bit 
 Basically the edible part - we refer to as the 'vegetable' is actually a type of enlarged root/ storage organ. In turnips, radish and carrots it's a type of taproot. The turnip is a 'napiform'  which means it's wide at the top and tapers to a narrower root. If you put its tail end in a bit of water it will sprout leaves and roots. The part that was above ground in the turnip is purple from the effect of sunlight and is actually part of the stem tissue but is fused with the root. The below ground part is white with the tapered root.

Supermarket turnips with leaves chopped off placed over water, on the upper left you can see the leaf and flower stem growth. ( there's a radish  hiding there too!)

How to do it and the limitations
 Look for a healthy looking turnip in the supermarket, preferably one that still has a small amount of lower root.  Place the tail ( white) end in water and top up on a regular basis to make sure it doesn't dry out. After about a week you will see small leaves emerging. You can plant it in a pot of soil at this stage but I kept mine in water. The bottom part of the turnip, which has been below ground will become more purple towards the base from the effect of daylight. The lower tapered root won't grow like the original root but will sprout lots of smaller roots. After about 6 weeks it will throw up a  tall flowering stem. If kept indoors the stem will be green but if you put it outside for a couple of days it will turn a lovely purple colour, eventually it will produce the yellow flowers. .

A bit more about the Turnip
I always think the turnip is overlooked. Pliny the elder certainly understood its importance and considered it to be one of the most important vegetables ( beneath beans). Being a biennial it can be kept in the ground for two years. In the first year the root grows and stores nutrients, in the second year it flowers, seeds and dies.  As a crop it has the potential to prevent famine as well as providing an important source of fodder for livestock. 

'Turnip' Townsend  and Four Field crop Rotation
The 2nd Viscount Townsend, known as 'Turnip Townsend' ( 1674- 1738) was a British Whig statesman and turnip fanatic! He's credited with introducing the four -field crop rotation system in England by adding turnips and clover to the existing rotation system which included wheat and barley, although there is some dispute over how influential he actually was....it's still a good story!

The introduction of turnips was certainly important, the introduction of turnips had already reduced the area of fallow land. But the new 'four - field' system meant the no field ever had to lie fallow because the clover being a nitrogen fixing plant introduced the nitrates to the soil and acted as a soil improver. Together the turnips and clover also served a purpose as animal feed, and reduced fallow land so nothing went to waste. This development in agriculture  had a huge impact on crop yield. To highlight the importance in 1705 England exported 11.5 million quarters of wheat, in 1765 this had increased to 95 million quarters.
With this in mind and in homage I think clover will make a nice addition to the turnip painting.....just need to find out which type of clover....

The Jade Vine

I don't often paint exotic or big bold plants! But things change and last month I started work on a larger work with the Fritillaria imperialis. It's a plant I've always loved but never had the nerve to try. I thought I'd probably never paint my favourite 'big' plants..... in fact it almost felt as though I couldn't or shouldn't paint them because that's not normally what I do. Last year something happened that got me thinking about new subjects when Beverly Allen invited me to join the Royal Botanic Garden Sydney  Florilegium Project. I was sent the plant list which was slightly daunting because many of the plants were not familiar subjects. I was immediately tempted by the Jade Vine, Strongylodon macrobotrys, and claimed it without giving too much thought to the scale of the job! Since that time I started to think about other appealing 'big' plants and have now compiled a short list  of plants that I really must try to paint while my eyesight isn't too bad...... more about that later. Here's my first effort and its story so far.

The Jade Vine is a member of the Fabaceae family - the nitrogen fixing legumes or peas and beans. It's a big woody vine! There's nothing else quite that colour in the plant world, it really is 'jade' or turquoise in colour and once seen is never forgotten. The colour is caused by the presence of the anthocyanin, malvin and the flavonoid, glucoside, saponarin. Together the cause this copigmentation. Apparently at night  the flowers look white, almost luminous! and like many white flowers it is pollinated by bats. It's native habitat is in the damp forests of the Philippines. Sadly loss of habitat has caused its decline and it's now considered endangered. 

I tracked down a specimen at Eden last year but was too late to make a start, so had to wait to visit Kew and Durham Botanic garden in April this year. I made preparatory sketches and was fortunate enough to collect the fallen flowers too (with permission form Durham). I returned home with colour studies, sketch book work, flowers and hundreds of photographs! Working from photographs in this way is a bit of a departure for me but it works OK if you've done the background research.

Fallen flowers. The colour changes from the jade green to a more blue and purple shade.

 It's going to be a bit of a long haul but after over a year waiting it's finally underway. This type of work can't be rushed and will no doubt take several months to get to the final painting.

I started by drawing out the plant in detail and painting in the supporting structure. The stalk has an underlying yellow/ green colour with a fairly dark purple on top. I used Green Gold for the first wash and a mix of Violet Dioxazine and Paynes Grey on top. 

Getting the structure in place

Thereafter I began to add the first wash to the flowers and found a mix of Winsor Blue Green Shade and Winsor Yellow worked well as a base colour. I also added some Violet Dioxazine for the older flowers and a little Manganese Blue Hue as a glaze in places.

First washes to the flowers

I'm currently starting to add detail to the flowers. But this is just the start of the job really. There's a second flower spike and the woody vine and leaves to add yet.....It may take some time!....and perhaps I'll forget the big plant paintings idea!

Slow progress

The work needs to be finished and delivered for the Florilegium project by March 2015.
