Bringing Nature Inside With These Classic Plants

This post is part of a series of exchanges between Urban Gardens and Seasonal Wisdom, exploring the latest in gardening, green living, and design. Teresa O’Connor shares her know-how for growing food in urban garden containers.
As autumn leaves fall and old man winter approaches, it’s more important than ever to stay connected with nature – even if that means bringing nature indoors now. Plants are one of the easiest ways to make your urban home more livable when the weather turns nasty. Here are some of my favorite indoor plants for this time of year. These classic favorites have brought color, charm, scent and even flavor to homes for centuries.
Is it any wonder evergreens have adorned winter homes since ancient times? The vibrant evergreens are a welcome sight when most plants are in dormancy or dead around this time. Ivy (Hedera spp.) is a popular evergreen for topiaries. The plant adds an elegant touch to any indoor décor, and enjoys a long tradition of decorating homes during winter holidays.
Topiaries made from cypress (Cupressus spp.) date back to ancient Rome, when Pliny the Elder described cypress topiary standards and other forms in the first century CE. These days, cypress topiaries of all types are easy enough to find for your urban home at local independent garden centers or online stores.
Topiaries made from rosemary (Rosmarinus officinalis) supply delicious, fresh herbs for cold-season meals. This culinary herb has long been known to be good for your memory and brain power too. As Shakespeare wrote in Hamlet, Act IV, Scene V, “There’s rosemary, that’s for remembrance: pray you love, remember.”
To care for your topiary, keep the plant near a sunny window with plenty of indirect light. Irrigate regularly but make sure plants have good drainage and don’t sit in water. Turn topiaries occasionally so they grow straight. Feed plants with a balanced water-soluble fertilizer, as instructed on the label. Always keep topiaries away from heated air vents so they don’t dry out. It’s a good idea to keep plants in rooms that are a bit cooler at night, so they stay fresh.
Just as fall is the time to plant spring-blooming bulbs outside, it’s also the right time to force bulbs to bloom indoors during the cold months. Some of the easiest bulbs to force are paperwhites (Narcissus papyraceus) and amaryllis (Hippeastrum hybrid), because they don’t require a chilling period like tulips and daffodils. You can find both types of bulbs at local garden centers or online stores.
Plant the bulbs in soil with plenty of drainage, or in a bowl with pebbles or marbles (just make sure the water doesn’t cover more than a quarter or third of the bottom of the bulbs.)
Provide indirect light and temperatures of about 50 degrees F. for the first two weeks, then warmer, brighter conditions after that. This will help keep stems short and sturdy. Cornell University also found that giving paperwhites a little alcohol controlled their height too.
For best results, look for bulbs that are nicely sized, firm and unblemished. By purchasing your bulbs now, you can ensure that you don’t get stuck with the leftovers no one else wanted.
If you stagger your plantings of paperwhites every couple weeks, you can enjoy these fragrant flowers all winter long.
Amaryllis is another easy and popular bulb to force now for winter blossoms. This exotic plant even decorated the home of Thomas Jefferson, who wrote a Philadelphia seedsman in 1811 that he enjoyed the “fine tulips, hyacinths, tuberoses & Amaryllis you formerly sent me.”
Your amaryllis bulb will need about six to eight weeks to bloom. Start bulbs by late October to ensure you’ll have flowers during the holidays and into the new year.
Just as with paperwhites, you can stagger amaryllis bulb plantings for continuous blooms. Amaryllis bulbs can be used again next year too. Let them lie dormant during the summer, and force them again next winter. Paperwhites, on the other hand, will not bloom again, so enjoy them this season and then toss in your compost pile.
Calamondin Orange Trees
With glossy dark green leaves, fragrant white flowers and golden orange fruits, there are lots to love about calamondin trees (X Citrofortunella mitis). Just as wealthy, 18th century Europeans had “orangeries” to grow potted citrus trees indoors, we can enjoy these charming trees in our urban homes – without any fancy settings or greenhouses.
Among the easiest citrus plants to grow indoors, calamondin trees need at least four hours of sunlight, preferably in a south- or east-facing window. This citrus tree doesn’t require humidity, making it less sensitive to dry indoor heat than other plants. Water the plant when the well-drained soil is dry to the touch, but before the trees shows signs of drooping.
With enough light, your indoor tree will produce flowers. But to set fruit, you’ll need to help the tree pollinate, playing the role for the helpful bees left, thankfully, outdoors. To pollinate your tree, use a small artist’s brush to transfer pollen from one flower to another, until all are pollinated. With a bit of luck, the pollination process will result in small fruit forming where the flowers were.
Calamondin trees produce small fruit that tastes a bit like lemon or lime, more than orange. Enjoy a slice or two in your drinks. Then raise your glass and pat yourself on the back for doing such an excellent job of bringing nature’s abundance into your urban home this fall and winter.
