Plants do so much for us and ask for so little in return. Simply being in their presence confers a broad range of benefits – when we are around them the air is cleaner and more humid, we are happier and less stressed, we work harder and more effectively, and we heal faster and feel less pain.
Indeed, we are wise to keep these living greens close by. Not only do they add beauty and lushness to your indoor spaces, choosing fragrant varieties means they can also take the place of artificial air fresheners too.
Here we’ve rounded up the most aromatic plants that adapt well to life indoors.

ENCOURAGING HOUSEPLANTS TO FLOWER
Some houseplants are more stubborn than others when it comes to flowering. The only way to see those marvellous blooms year after year is to recreate their natural environment as best you can.
Here are a few tips:
Lighting – Some plants require more light than your sunniest window sill, especially if you live in the northern hemisphere. Supplement their sunlight needs by adding a grow light or two.
Humidity – To increase humidity levels in the home, place pebble trays beneath your planters. You can also give their foliage a daily spritz with plain water. Investing in a humidifier, grouping houseplants closely together, or setting them in a terrarium are other ways to keep tropical plants happy.
Repotting – Flowering takes up a lot of the plant’s energy. Replenish their nutrients by repotting plants in new potting soil every year.
Put them out – Consider setting plants outside during the summer months to give them a major boost of growth. Just be sure to bring them back inside before the temperature drops.
