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!

Turnip watercolour May 2014

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....

Vegetable Study, SBA Assignment 8, Savoy Cabbage

An unfinished savoy

Assignment 8 Vegetable or Fungi Study
The Savoy cabbage. This time I really regretted starting such a large and complex subject - it completely filled the paper! I find this paper size so restrictive! I like to have lots of white space so working so small means that if you want white space then you could only work on small subjects. I'd spent so much time on this and I felt I had to continue....I passed the point of no return. I didn't manage to finish it but that was OK as long as two leaves were finished and all the preliminary washes were in place. Perhaps I'll go back to it one day.....but not just yet. I couldn't find any vegetables that hadn't been decapitated ( no leaves) for this study so the choices were a bit limited, so I decided to grow some of my own veg for future studies.
Fungi is no longer allowed in future courses as DNA evidence has finally confirmed that fungi has no place in the plant world. And a lot of what is sold as vegetable is actually fruit, so it's a bit limited.

I was cheating again here because I've painted a Savoy Cabbage before! Yes playing safe again. Actually I think all subjects should be painted more than once, it's the only way to really get to grips with them.

My tutor was Billy Showell, she congratulated me on taking on such a large task! She must think I'm crazy! The criticism was on the tone and colour section. She felt some of the highlights could be toned down in the shaded areas to give more emphasis to the lighter parts. Totally agree with that looking at it now. I got so wrapped up painting all those little 'bubbles' that I lost track of the overall light and shade. It was a very dark variety, with a lot of blue in the green. I was happy with the leaf ribs and veins. it was a good mark so happy enough. Billy said she'd like to see it finished....hmmm maybe one day!
