Austral Gem™ Bird's Nest Fern adapts to the low humidity levels found in most homes. Dark green, feathery fronds make it an attractive addition to your windowsill garden, and it doesn't produce messy spores that scatter on tabletops and floors. If you move it outdoors after the last spring frost, give it full shade.
Pot up your coleus before the first frost to overwinter them as colorful, showy houseplants. Coleus grow nicely in an eastern exposure, and if they start to look leggy and stretched, simply prune them back. Stick the cuttings into a glass of water or a small container filled with potting mix, and roots will soon form, increasing your windowsill garden. Shown here: Coleus 'Sun Rose To Lime Magic'
If you can provide impatiens with enough humidity, these pretty annuals will add color to your windowsill garden for weeks. While they tolerate the average home temperature, they need at least 50% humidity. Group them with other plants, grow them in a bathroom or near the kitchen sink, or sit their pots in shallow trays filled with pebbles and a little water to give them the moisture they need. Another option: mist your impatiens daily.
Start your own seeds indoors with a windowsill propagation kit. This type of kit includes everything you need to sprout a crop of basil or chives for a windowsill herb garden. The covers for the containers provide a greenhouse effect, but also offer the option of venting open to prevent heat and moisture build up.

For the most part, mint is an aggressive plant in the garden, which makes it an ideal herb for your indoor garden. Its vigorous growth isn’t dampened by growing conditions inside. As long as it has a sunny windowsill, it will reward you with flavorful leaves, no matter the season. Snip stems often to keep the plant bushy and unfurling new leaves, which pack the mintiest punch.
Before frost arrives, take cuttings of favorite plants, like coleus, plectranthus, or scented geraniums. Stem tip cuttings from these plants root easily to allow you to overwinter starts for next year’s containers. Also take cuttings of herbs like pineapple sage, Greek basil, mint and basil to root in water and transplant into pots to grow garden fresh flavors on your windowsill.
