Planning a garden is supposed to be fun! Yet I grew frustrated looking for plant heights - not even shown on all the seed packets much to my surprise! How should I know which plants to put in the middle of the garden (the tallest veggies) and which to plant around the edges (other than the obvious to me chives)? Finally I found
Vegetables - List of Vegetables and Vegetable Varieties. Plant Encyclopedia - BHG.com which does list plant heights & other good info, too.
