If I had a class of students, I would send the list of FREE SEED CATALOGS home so parents can order for rainy day reading. This is free education at it's best, in my humble opinion.
If we can inspire children (and adults) to learn about nutrition, biodiversity and self-sustaining agriculture, perhaps they will learn to make more intelligent food choices and promote healthier living. I have read many seed catalogs in their entirety. I believe and hope future generations will come to understand how wonderful growing our own organic food and saving seed truly is. My daughter Ava understood what a seed was long before her second birthday. It is never too early to give the gift of gardening to our babies.
Let us also teach our children what an heirloom vegetable is, how to save seeds, and which seeds can even be saved! Have fun. Grow something and happy harvesting!
A few to get you started:
Baker Creek Heirloom Seeds
