My girlfriend loves to cook and always is dropping the idea that would she would love to be adding fresh herbs, fruits, vegetables, and ect. Problem is we currently living downtown Denver in a an apartment. I was thinking maybe I could get her some plants to add next to the window? The inside window ledge is about 40 inches in length and 5 inches deep. It tends to get some good sun later in the afternoon for about 4 hours. I haven't a clue about types of plants and their needed environment conditions or if this idea is even feasible with ANY plant. Could someone recommend me different ideas of plants that she would enjoy to cook with that could fit inside this window?
