Seed of the Week: Pumpkins

Time to reveal the identity of the mystery seeds from last week.

I really thought the bright orange pulp would give these away. They are pumpkin seeds!

The common name pumpkin is given to several species of related plants. Most often pumpkins are Cucurbita pepo and Cucurbita mixta. Certain varieties of  Cucurbita maxima and Cucurbita moschata may also be called pumpkins. The terms pumpkin and squash can be quite confusing because they are basically varieties of the same thing.

Pumpkins are thought to originate from in the New World. The scientists found some preserved ancient seeds in Mexico, which they identified as pumpkins. (Just think, the ability to identify mystery seeds is important when you are trying to trace the ancestry of plants! And you thought we were just having fun).

Pumpkins are relatively easy to grow if you have plenty of space in your garden.

You can try to save seeds and grow your own pumpkin, but the results might not look anything like what you started with because the plants are often cross pollinated with other varieties. Maybe you’ll come up with the next great type of pumpkin.

The seeds will sprout even when they are fresh from the fruit, they don’t need to overwinter or go through a cold period.

The plant is a long, trailing vine with large, lobed leaves.

Pumpkins have large, orange five-lobed flower.  The flowers are separate, either male or female.

Pumpkins are such popular plants you can find a wealth of information about them in books and on the Internet.

Here are some of our favorites:
All About Pumpkins website has history, etc.

The seeds are edible as well as the fruit. Check this recipe for roasting pumpkin seeds.

Pick Your Own has detailed information on how to make a pie from fresh pumpkin. It works!

Pumpkin Circle is a wonderful picture book, and the website has classroom activities.

Seed of the Week: Carrot

Did you guess what the mystery seeds were last week? Here’s a hint:

Yes, those spiky-looking seeds will grow into carrots.

The carrot, Daucus carota, is a biennial. That means in the first year it stores up food in its extra large root. If you leave the root in the ground and conditions are right, at the end of the second season the plant will flower and produce seeds.

This is a bud.

Starting to open…

almost there…

flowering!

Along come the little bees to pollinate the flowers. Don’t the flower clusters look like miniature bouquets?

And then you have seeds. Why do you think the seeds have those spines on them?

If you would like to learn more about carrots, the World Carrot Museum has an entire page of excellent experiments and activities to do with carrots for kids, plus oodles of information about the history and uses of carrots.

One fun activity to do with carrots from the grocery store is to take the tops (that you cut off anyway when you eat them) and set them cut end down in a small dish of pebbles. (See the photograph above). Cover half way with water, allowing the green part to be exposed to the air. Keep the bottom covered with water and the cut tops should start to sprout.

Make this into an experiment by comparing the ability of the tops to sprout to the ability of sections further down the root. Will a “baby carrot” sprout?

This fun post is thanks to my son, who asked the simple question:  Can you grow a carrot plant by planting a carrot root you buy in the store? The answer is:  as long as there’s some green at the top of the carrot, it will grow into a plant that produces seeds (if grown during the correct season for your climate). The root is no longer edible, but you can try planting the seeds next year.

Have you ever had a carrot plant go to seed?
