This is the story of Jessica, and how she learned to save and grow the seeds of her favourite heritage tomato. It is also the story of the people who research the extraordinary benefits of that tomato and how they selflessly gave away the secret for the common good.
Mark Christensen of the Heritage Food Crops Research Trust is a firm believer in the health benefits of the golden orange tomato, one variety being the Tangella.
Last year, the trust produced a children's book, Jessica and the Golden Orb - written and illustrated by Janet Bradbury - in which Jessica grew a golden orange tomato plant and learned the health secrets of the heritage plant.
This year Janet has produced another book, Jessica the Seed Saver, in which Jessica's tomato plant finishes fruiting and - being a talking tomato plant - suggests Jessica plant some seeds to continue growing the golden orange fruit. The story is of the young girl's successful search for someone who saved some seeds. The book includes recipes, planting instructions and a packet of seeds.
The book is educational, giving young readers information about this remarkable heritage tomato and how it differs from, and is better than, regular red tomatoes.
"Over the last few hundred years, food has been altered dramatically and a lot of the health benefits have been diminished," says Mark. "What we've done with this tomato research is find a compound that has been lost from the modern tomato."
That compound is tetra-cis-lycopene, a more easily absorbed form of lycopene than found in red tomatoes. Lycopene has many health benefits, including resistance to various cancers.
"We've grown a number of these varieties, we're picking the best and we want to further research to prove the health benefits.
"We want to get it out to the community as quickly as possible because they can be at the cutting edge of the research."
Mark says he has heard that a person allergic to tomatoes can eat the Tangella variety with no ill effects.
Being able to follow one's passion is something many scientists are denied, as funding is often about the business aspect of research, and there is very little public good research as a result.
"If you co-ordinate the right project with the right people, you can get the right answer, if your intention is right," he says.
The books are free, thanks to an anonymous local donor.
"We are a charitable trust and we get lots of support from the community and we rely on philanthropic individuals from time to time," says Mark.
"This year we are not giving books out with the plants, not distributing them at the markets, but sending them out to schools with a covering letter," says Janet.
Getting children interested and actively growing the tomatoes is an investment in the future of the plant and community health. Tomato plants will be distributed free at the River Traders Markets later this month.
Jessica the Seed Saver is available from Paige's Book Gallery, Delicious Cafe, Renata's Art and Framing, Frank Bristol's plant stall at the River Traders Market and Natasha Huntley at the Wisdom is Yours Healing Space at 208 Victoria Ave (next to the AA) or from the Heritage Food Crops Research Trust.
