The 4th Graders explored the Garden Classroom and planted potatoes and nasturtium seeds this spring.
They planted nasturtium seeds in our herb boxes as well as in two of our our clear-sided planter boxes. They all knew that herbs are used for beauty in the garden, to attract pollinators, to flavor food, and for medicine.
The leaves, flowers, and seeds of the nasturtium are all edible. The seeds can be pickled and eaten like capers! Nasturtium have more lutein than any other edible plant, which is good for your eyes. They also contain vitamin C and were used to help with chest congestion. We talked about how the seed’s hard shell protects it from predators and moisture.
Scraping at the seed coat with sandpaper and soaking it overnight allows the water in to soften the shell, so it can germinate more quickly.
They also planted potatoes in some fabric sacks right above the garden classroom. While potatoes do form seeds in the berries that grow from the greens, we usually grow potatoes by planting actual potatoes! Roots and shoots will grow from the eyes and new potatoes will grow off of the roots.
You never want to eat a green potato, because that means it’s been exposed to sunlight. When exposed to sunlight they create a toxin called solanine. The green color is actually just chorophyll, which is not dangerous, but it gives us a clue that they must have been exposed to sunlight.
We also had fun smelling all of the herbs in the herb boxes. Check out the lemon thyme and chocolate mint!
