Scents of the season

A year of scented plants



Gardeners and landscape designers always think about size and hardiness and flower color and bark and shape when designing and planting a garden. But there is another dimension worth considering: scent. It's easy to include a few shrubs, trees, perennials and bulbs with scented leaves or flowers.

Herbs are one of the easiest ways to incorporate scent into the garden. Culinary sage, for example, is a beautiful plant with its silvery gray foliage. Remember to plant your scented-leaved plants near a walkway so you can rub your hand across them as you walk to the house.

Most scented flowers release their scent into the air and share it with everyone. Others are called "fast" with their scent, meaning you have to stick your nose into the flower to smell anything.

Here are some of my favorite scented plants throughout the year. There are dozens and dozens more waiting to be discovered and planted in your garden.

January: Wintersweet (Chimonanthus praecox)

Most of the year, wintersweet fades into the background of the shrub border. It isn't flashy. The large leaves turn a pretty yellow in autumn, still not flashy. Come January, however, the bare branches will be covered with tiny, downward-facing, cup-shaped, waxy yellow flowers with a spicy, intoxicating fragrance. You'll be able to smell them long before you notice the shrub is in bloom. It's a tough shrub that can handle our summers and winters with little fuss. It grows about 6 feet tall, doesn't spread much and asks little in return except regular watering. Like most plants, it prefers a bit of afternoon shade.

February: Daphne (Daphne odora)

I have five Daphne odora aureomarginata shrubs planted along the front walkway to my house. They have gold edges to the leaves, rather than solid green. Daphnes can easily grow to 4 feet wide and about 3 feet tall, so I give them plenty of room to spread. They tolerate some pruning, but never look good if you have to whack them back to keep them from overtaking a walkway. They have a reputation for being finicky and for sometimes dying suddenly for no apparent reason. That reputation is well deserved. If your daphne dies, buy another and plant it in a different place. They appreciate regular watering, but don't require a lot. They also prefer morning sun, especially during our hot California summers. When my five daphnes are in bloom, the scent is almost overwhelming. I cut one tiny sprig of flowers to bring in the house.

March: Bearded irises (Iris germanica)

These are the common irises you see everywhere during the early spring. The classic purple ones are the first to appear, even before winter has finished. Next come the white ones. After that, it's full speed ahead, as irises in every hue and color combination steal the show. The flowers are scented, but you have to get close to appreciate it. Somehow, to me, the purple irises smell, well, purple.

They're called "bearded" because of the row of fuzzy hairs on each of the downward-facing petals. These drooping petals give insects a place to land and the colorful markings act as a guide to the nectar. The beards give bees and other insects a place to hang on.

Irises are tough plants to place. In bloom, they're beautiful. After that, the foliage can get a little tattered and tired, and in the middle of summer, they need to be cut back to the ground. Always plant irises among other plants, so conceivably you can disguise their dying foliage.

April: Heritage roses

Nothing beats the heavenly scent of old-fashioned roses. You could almost throw a dart at a list and come up with something you'll love. They're also called "old roses."

The definition of an old rose is one that existed before 1867. That was the year the first hybrid tea rose was introduced. They're a rather diverse group, but what most have in common is disease resistance and fragrance. They're divided into several classifications—damasks, gallicas, albas, floribundas, centifolias and moss, to name a few—and each comes with a bit of history and often a romantic-sounding name.

If you live near Sacramento, be sure to visit the world-renowned heritage rose garden in the Sacramento Historic City Cemetery. The area near the Broadway entrance is filled with old roses and they're all labeled. One of my favorites is Duchesse de Brabant. It's a blousy pink rose. Legend has it this was Teddy Roosevelt's favorite rose, and he often had one in his lapel when they were blooming.

May: Jasmine (Jasminum officinale)

Mention fragrance, and almost everyone knows about jasmine. In textbooks, this jasmine is called the "common jasmine." I prefer the nickname "poet's jasmine." It's a mainly evergreen vine that dependably blooms from early summer into the fall. It's a great plant to clamber up a trellis. The long vines twine themselves around the trellis. It is an enthusiastic grower and should be cut back somewhat severely just before the spring growth begins. In bloom, one small sprig is enough to scent a room.

They have a long bloom period, often extending well into summer. They don't require a lot of water, but do best with regular watering. Deprived of water, they seldom flower.

June: Gardenia (Gardenia jasminoides, also called Gardenia augusta)

When I was a child, I remember a gardenia planted outside the bedroom window. On hot summer nights when the plant was in bloom, the scent of the flowers would waft into the open windows. I love the smell of gardenias, and try as I might, I've never found a lotion or any gardenia-scented product to be close to the real thing.

The white flowers contrast nicely against the dark green foliage. Gardenias prefer acid soil, demand plenty of water and don't like to be jammed up against other plants. The variety called "Mystery" can grow as tall as 6 feet. Most, however, are mounding shrubs. They respond well to clipping, and even if you clip off the flower buds, the plant will produce flowers lower on the stems. They are mainly cold-tolerant, but in higher elevations there will be frost damage. If it isn't severe enough to kill the plant, you can just cut away the bad bits when spring arrives.
