Uncommon Fruits and Vegetables – Heritage Potatoes

Fascinating and Often Forgotten Fruit & Vegetables – How to Grow and Use Them

History

American horticulturalist Luther Burbank perfected over 800 strains and varieties of plants including the Burbank and the Russet Burbank Potato. In a lifetime of plant breeding experiments he is best known for the potatoes, the Crimson Winter Rhubarb, Shasta daisy, Satsuma Plum, Iceland Cucumber and July Elberta Peach. In the year 1900 alone, Burbank introduced over 90 vegetables to gardeners across America. While he was a prolific plant breeder and instrumental with Thomas Edison to support Paul Stark Sr. in his fight to get patent legislation passed for plant breeders, he was not the first to cultivate heirloom or heritage varieties of the humble spud.

The Inca Indians in Peru were the first to cultivate potatoes around 8,000 BC to 5,000 B.C. In 1536 Spanish Conquistadors conquered Peru, discovered the flavors of the potato, and carried them to Europe.

Sir Walter Raleigh introduced potatoes to Ireland in 1589 on the 40,000 acres of land near Cork. It took nearly four decades for the potato to spread to the rest of Europe.

Eventually, agriculturalists in Europe found potatoes easier to grow and cultivate than other staple crops, such as wheat and oats. Most importantly, it became known that potatoes contained most of the vitamins needed for sustenance, and they could be provided to nearly 10 people for each acre of land cultivated.

Potatoes arrived in the American Colonies in 1621 when the Governor of Bermuda, Nathaniel Butler, sent two large cedar chests containing potatoes and other vegetables to Governor Francis Wyatt of Virginia at Jamestown. The first permanent potato patches in North America were established in 1719, most likely near Londonderry (Derry), NH, by Scotch-Irish immigrants. From there, the crop spread across the country.

A. Parmentier helped King Louis XIV popularize the potato in France in the 18th century. Parmentier created a feast with only potato dishes, a concept he realized was possible when he was imprisoned in Germany and fed only potatoes. Benjamin Franklin, ambassador to France, was in attendance of Parmentier’s feast in 1767.

Idaho, the present-day largest producer of potatoes in America, actually did not begin growing potatoes until 1836, when missionaries moved west in an effort to teach the native tribes to grow crops instead of relying upon hunting and gathering methods (whether this is true or not of the native indigenous tribes is questionable). However, it wasn’t until 1872 when the Russet Burbank variety was developed, that the Idaho potato industry began to flourish.

In October 1995, the potato became the first vegetable to be grown in space. NASA and the University of Wisconsin, Madison, created the technology with the goal of feeding astronauts on long space voyages, and eventually, feeding future space colonies.

The potato was originally believed to have been domesticated by indigenous peoples of the Americas independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.

Potato plants are herbaceous perennials that grow about 60 cm (24 in) high, depending on variety, with the leaves dying back after flowering, fruiting, and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens. In general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bees, which carry pollen from other potato plants, though a substantial amount of self-fertilizing occurs as well. Tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties.

After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 seeds. Like all parts of the plant except the tubers, the fruit contains the toxic alkaloid solanine and is therefore unsuitable for consumption. All new potato varieties are grown from seeds, also called “true potato seed”, “TPS” or “botanical seed” to distinguish it from seed tubers. New varieties grown from seed can be propagated vegetatively by planting tubers, pieces of tubers cut to include at least one or two eyes, or cuttings, a practice used in greenhouses for the production of healthy seed tubers. Plants propagated from tubers are clones of the parent, whereas those propagated from seed produce a range of different varieties.

Varieties

A full list of potato varieties.

There are close to 4,000 varieties of potato including common commercial varieties, each of which has specific agricultural or culinary attributes. Around 80 varieties are commercially available.  In general, varieties are categorized into a few main groups based on common characteristics, such as russet potatoes (rough brown skin), red potatoes, white potatoes, yellow potatoes (also called Yukon potatoes), and purple potatoes.

For culinary purposes, varieties are often differentiated by their waxiness: floury or mealy baking potatoes have more starch (20–22%) than waxy boiling potatoes (16–18%). The distinction may also arise from variation in the comparative ratio of two different potato starch compounds: amylose and amylopectin. Amylose, a long-chain molecule, diffuses from the starch granule when cooked in water, and lends itself to dishes where the potato is mashed. Varieties that contain a slightly higher amylopectin content, which is a highly branched molecule, help the potato retain its shape after being boiled in water. Potatoes that are good for making potato chips or potato crisps are sometimes called “chipping potatoes”, which means they meet the basic requirements of similar varietal characteristics, being firm, fairly clean, and fairly well-shaped.

The European Cultivated Potato Database (ECPD) is an online collaborative database of potato variety descriptions that is updated and maintained by the Scottish Agricultural Science Agency.

Dozens of potato cultivars have been selectively bred specifically for their skin or, more commonly, flesh color, including gold, red, and blue varieties that contain varying amounts of phytochemicals, including carotenoids for gold/yellow or polyphenols for red or blue cultivars. 

Peruvian Potato

High in the Peruvian Andes, agronomists are looking to the ancestral knowledge of farmers to identify genetic strains which could help the tubers survive increasingly frequent and intense droughts, floods and frosts.

The Potato Park in Cusco is a 90 sq km (35 sq mile) expanse ranging from 3,400 to 4,900 metres (16,000 feet) above sea level. It has “maintained one of the highest diversities of native potatoes in the world, in a constant process of evolution,” says Alejandro Argumedo, the founder of Asociación Andes, an NGO which supports the park.

Companies like GreenHarvest in Australia are working to bring back the diversity of potato planting in our urban and rural vegetable gardens. do yourself and your taste buds a favour and get some diversity into your potato bakes.

The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially Northern and Eastern Europe, where per capita production is still the highest in the world, while the most rapid expansion in production over the past few decades has occurred in southern and eastern Asia, with China and India leading the world in overall production as of 2018.

Like the tomato, the potato is nightshade in the genus Solanum, and the vegetative and fruiting parts of the potato contain the toxin solanine which is dangerous for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible to human health, but if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.

There are literally thousands of ways to use potatoes, from boiling, mashing, roasting and deep frying. But here we present some not so well known methods.

With so many varieties of Potato to play with we really have so much diversity in flavour and colour. Versatility is the name of the game here. So many of the heirloom vegetables we grow can be used in a multitude of ways. You are only limited by your imagination. The only question remaining is – Will you be planting potato varieties this spring? I know I will.
