The great zupumpkin!

124_2466.jpgIn one of my first small gardens, I planted a pumpkin plant and a zucchini plant next to each other.  I didn’t save any of their seeds, but the next year, when I spotted a pumpkin plant coming up from the compost, I let it grow.  It started out looking like a bit like an elongated pumpkin or some sort of squash.  Then it ripened to the above specimen, which was christened the zupumpkin.

Cross-pollination

Cross-pollination occurs when an insect or the wind carries pollen from one variety of plant to another.  The resulting seed, when planted, sprouts a hybrid of its parents.  Since zucchini and pumpkins are both varieties of the same species, they can create the zupumkin (or zumption or pumcchini–your choice) but a cucumber and squash can’t procreate because they’re different species.

Cross-pollination does not affect the current year’s crop, but rather the next year–with one exception: corn.  If the pollen from the tassels of one variety of corn are blown into the silks from another variety, the cob that develops is a hybrid.

Self-pollinating plants

Vegetables like beans, peas, peanuts, eggplant, peppers, lettuce, and tomatoes are self-pollinating. Their seeds will produce plants like the parent, but insects will occasionally cross them, so if you want to be absolutely certain that your seeds will grow true to type, plant each variety at least 10 feet apart.

Insect- and wind-pollinated plants

Vegetables that are pollinated by insects or wind need to be separated by variety, and grown a distance apart (the distance varies with each type of plant).   To ensure that your seeds grow true to type, grow one variety of each type, or separate the different varieties.

Vegetables that willingly cross-breed

The following plants or plant families are prone to cross-pollination.  If you are planting them with the intention of keeping their seeds, keep varieties well separated.

  • Beets and Swiss chard
  • Cauliflower, cabbage, kale, Brussels sprouts, kale, collard greens, and broccoli
  • Corn
  • Cucumbers
  • Honeydew, cantaloupe, and other melons, excluding watermelons
  • Peppers (hot and sweet)
  • Squash (some varieties)
  • Zucchini and pumpkins

From the side dish to the main course

Recent studies have shown that the ideal diet is one that is rich in vegetables and fruits.  The benefits to our health increase if we go beyond the traditional options, such as carrots, potatoes, and beans, and eat a wide variety of vegetables and fruits.  No one plant contains all of the nutrients we need, so it’s best to mix it up, and enjoy a rainbow of colours, textures, and types.

Health benefits

The benefits are widespread:

A diet rich in vegetables and fruits can lower blood pressure, reduce risk of heart disease and stroke, prevent some types of cancer, lower risk of eye and digestive problems, and have a positive effect upon blood sugar which can help keep appetite in check. (source)

There is a growing body of evidence suggesting that dietary patterns emphasizing fruits and vegetables may be linked to better psychological health.[i] A recent study found that higher fruit and vegetable consumption may increase well-being, curiosity and creativity, possibly related to micronutrients and carbohydrate composition.[ii] This is probably related to the fact you are giving your body and brain more healthy vitamins, minerals, phytochemicals and fiber.

Meatless Monday

The Meatless Monday campaign, which started in 2003, encourages participants to abstain from meat on Mondays as a way to improve their health and that of the planet.  Why not expand this campaign to your garden, and try to grow a favourite vegetable, or something new, and use it as a centrepiece for your Monday meals?

Fun vegetables to grow

Here are some suggestions for interesting and healthy vegetables to try:

  • Rainbow chard is rich in vitamins.  There are many ways to cook it, or you can enjoy it in salads.  You can use it as a replacement for recipes that call for cooked spinach.
  • Sweet potatoes are extremely high in vitamin A and rich in fibre.  They are delicious baked and in soups.
  • Beets are versatile.  You can eat the greens or the beetroots themselves, or grate them and add them to cake.  They come in a variety of colours, like red, gold, and white.  They’re high in folates, iron, and other minerals.
  • Kale, like most green vegetables, is high in iron.  It likes the cold weather and doesn’t mind a little snow.
  • Eggplants/aubergines are often used as replacements for meat.  There are several varieties to choose from.
  • Winter squash are great in soups, casseroles, or as side dishes.  You can grow them in many colours and unusual shapes.
  • Ground cherries taste like a combination between pineapples and strawberries.  They can be eaten fresh or used in preserves, pies, and other sweet treats.
