Growing Your Own Rainbow

This year I had a go at growing something of a horticultural novelty. You may have seen images of Glass Gem corn on Facebook, Twitter and Instagram, and like millions of other people thought, that's been photoshopped, corn isn't that colour, it's not real. Well, I can now confirm, it is!

"The thankful receiver bears a plentiful harvest."

At the beginning of the year I was gifted (from an extremely generous, and rather lovely new gardening friend) with a small brown envelope containing a small amount of the precious seed, and after reading up on when to sow, where to place and how much water to give, I planted the precious, but rather unpromising looking dried out brown seed and waited.

Glass gem corn is a stunning variety selected over many years by Carl Barnes, a part-Cherokee farmer and breeder from Oklahoma, now famous for his work in collecting and preserving rare varieties of native crops. Selected from crossing several traditional, heritage corn varieties and saving seed from the vivid, translucent kernels Glass Gem corn is being shared and grown around the world. By saving the corn ears that have the best colour variations to dry out for their seed, the following year's harvest is more likely to continue to have good colours.

My little supply came from a lovely grower who trials new varieties of all sorts of plants, is passionate about heritage varieties, and writes about his results. He's a lovely guy, and offered to send me some of the Glass Gem corn seed to have a go at growing, and painting. With just a handful of seed to play with, I was a bit apprehensive, and only planted a few, to give it a go. It's pretty straightforward to grow, but gets huge! And although you can get quite a few cobs, it's all a lottery when you grow this stuff, as you can't tell from the outside, how colourful it will be on the inside. When it was getting to about 7ft tall with a number of swelling cobs, I was pretty sure we would get something out if it.   

The advice I was given is that it's best to wait until the leaves around the cob are beginning to yellow before you harvest it, and waiting was the hardest part. However, this week I was able to start bringing in my few cobs of corn to see what I had managed to get. The first two, although pretty were a bit devoid of the now famous, vibrant gemstone hues, with paler blues and pinks, or a mixed combo of yellows.

As with all plants, the harvest and colours of the corn are determined by the conditions
How much rain or sunshine or the position where the plants are grown will all have an impact on the colours.

it's best to wait as long as possible too. |I think this one could have been left a little longer,
to help the colours to develop a little more  

Number three however, came up with something really quite astonishing. After peeling off the papery husk, a bit like pass the parcel, the colours were slowly revealed. Just how good they would be, I had no idea, and was completely bowled over by the multicoloured, glistening pearls that eventually came out.

It has been a very great privilege to grow this most unique, and rare variety, and like many who have a go, I am completely hooked. Now to dry out the best of my corn, ready to sow for next year.

Well, being unsure if the glass gem would actually be successful, I hedged my bets and had a go with another variety of corn that caught my eye. Having seen these before in the Sarah Raven catalogue, and being quite intrigued by their deep maroon colouring, I decided to give Strawberry corn a try.

Choices, choices, choices. Hmmm
