I am fortunate enough to finally have a bright apartment where plants grow well. In the past our places were too shady to grow anything or the windows would not accommodate them. Though decorative plants are nice, and I have a few that serve only that purpose, I like my plants to earn their keep and save me money.
I have a row of cabbage growing in our bedroom. The blue tones in the cabbage incorporate really well with the rest of the room which has blue accents and pillows. And while the cabbage looks good in the room, we do still intend to eat the mature plants and then start again.
In the living room, we have eight pots of herbs. I was buying a lot of fresh herbs for cooking and I hated how pricey they were and how quickly they went south in the fridge. Now if I need some fresh herbs I can just harvest a few leaves from my mini garden. It should save me about $3-7 per week.
