Gardening in our house

Did you know that the vanilla bean comes from a orchid varietal? And it's not the only sweet-smelling kind: "An oncidum hyrbrid called Sharry Baby smells like chocolate," says George Hatfield, president of the Santa Barbara Orchid Show. "It's 'baking cookie' aroma has made it a winner." And that's not all: The cymbidium Golden Elf smells lemony, and the phalaenopsis violacea has a cinnamon scent. "Just like you'd combine Jelly Belly beans to create new flavors, you can combine orchids to create a garden that smells like a dessert buffet," says Hatfield.

A regular sprinkling of this kitchen staple into your plant's soil can help reduce acidity, which sweetens up your crop.

Colorful blooms aren't the chief reason these insects love your garden – it's more about the fragrance and nectar. According to the Smithsonian Institute, new cultivars of popular flowers have been bred for enhanced color and size, but have often lost their fragrance in the process. So everyday weeds, like dandelions and clovers, might actually be the most appealing things in your yard to butterflies (they hate pesticides, too). Taking care to choose heirloom flower seeds can get them to also fly your way.

Talking to plants to help them grow is a well-known old wives' tale, but studies have shown vibration (like music, or perhaps even the sweet sound of your voice) can affect plant growth. Plus, the Myth Busters (in an admittedly not-so-scientific study), compared a silent greenhouse to one where they piped in a voice soundtrack, and found that plants in the latter grew more.

It's aliiiiive! OK, in all seriousness, that fact might make you itchy, but microbes are important for keeping your soil full of nutrients.

Both the fuzzy brown center and the classic yellow petals are actually 1,000 – 2,000 individual flowers, held together on a single stalk.
