Fragrant Plants in the Garden

It was an especially fragrant bouquet of roses on my dining table this week that got me thinking about what an incredible thing our sense of smell is. it?s the only sense that has a direct connection to our brains. We can detect at least a trillion distinct scents. Our scent cells are renewed every 30 to 60 days. Some of the most pleasurable scents, according to recent research, include vanilla, some orange scents, cinnamon, crayons and cookies. I don?t have any crayon or cookie scented flowers but wouldn?t that be a great addition in the garden?

Chinese lilac

Where does fragrance come from? Fragrance in flowers is nature’s ways of encouraging pollination. Just as it draws you to take a deeper whiff, it lures insects to blossoms hidden by leaves and other plants. Some flowers are fragrant only at night and attract only night-flying pollinators like moths, while others are more fragrant only during the day and attract insects like bees and butterflies. The fragrance itself comes from essential oils called attars that vaporize easily and infuse the air with their scents. They are present in different combinations in different plants, but often they are markedly similar which is why there are irises that smell like grapes and roses that smell like licorice.

Pink wisteria

Place sweet-smelling plants where you can enjoy them throughout the season. The potency of flower scents varies greatly, so consider the strength of a fragrance when deciding where to put a plant. Subtle fragrances such as sweet peas. lemon verbenas, scented geraniums and chocolate cosmos smell wonderful right outside the back door. Add stronger scents where people naturally congregate- decks, pools and spa areas, dining alcoves, gazebos. Stargazer lilies, jasmine, lilacs, daphne, citrus and peonies will make your guests linger.

Your front entry should have fragrant plants to greet you when you come home. Train a fragrant climbing rose over a pergola at the gate. Fill some of the containers in your entry with scented bedding plants like dianthus , nemesia, freesias, stock or aromatic evergreens like rosemary and lavender. Plant sweet smelling shrubs like Mexican orange, buddleja, or philadelphus beside a path. Or plant carnations or lavender next to a garden bench or near your hammock.

Brugmanansia

Be sure to include fragrant plants that release their scent in the evening, especially in the areas of the garden you most frequent after dark. Since the majority of night-scented blossoms have white flowers, these plants also light up the landscape at night. Angel trumpet or brugmansia is one such plant as is flowering tobacco and night blooming jessamine.

Several easy-to-grow shrubs have fragrant flowers as an added bonus. Choisya blooms smell like oranges as does pittosporum eugenoides, tenuifolium and tobira. The tiny flower cluster of Fragrant Olive or osmanthus have a delicate apricot fragrance.

Philadelphus lewisii

Other fragrant plants include California native Philadelphus lewisii. Calycanthus occidentals is native to our Central and Northern California mountains. Their fragrant burgundy flowers smell like red wine. Ribes viburnifolium, carpenteria californica and rosa californica are mildly scented, too.

Ideally, when you’ve finished, your garden will smell as intriguing as an expensive perfume. The top note will be floral- jasmine, honeysuckle, rose. The middle register will be spicy, such as the vanilla of heliotrope or purple petunias or the clove of dianthus. Finally, underneath the tones that give perfumes their vigor, like artemisia, sage and santolina.

Not every inch of the garden needs to be fragrant but a waft or two of fragrance from the right plants can turn a garden from ordinary to enchanting.

Fragrance in the Garden

A sweet fragrance permeates the air as I step out my front door. Could it be the white flowering wild ceanothus cuneatus blooming now on the hillside and smells of plum blossoms and roses? Maybe the scent is coming from the fragrant sarcococca with those tiny white flowers you can barely see but can smell a mile away. Or could it be the sweetly scented lily-of-the-valley flowers blooming on the back patio? Make fragrance a daily delight with plants that release their perfume at different times of the day and the year.

Daphne odora ‘Maejima’

The word fragrance comes from the 17th century French word fragrantia meaning sweet smell. A garden’s fragrance can be as unforgettable as its appearance. The scent of a particular flower can make you remember past times and places. Plant them along a garden path to enjoy as you stroll, in containers to scent a deck or patio or locate them beneath a window and let their aroma drift indoors.

Several easy-to-grow shrubs have fragrant flowers as an added bonus. Mexican Orange or choisya ternata blooms most of the year. Pittosporum eugenoides, tenuifolium and tobira all have tiny blossoms that also smell like oranges. The tiny flower cluster of Fragrant Olive or osmanthus have a delicate apricot fragrance.

Iris pallida ‘Variegata’ – Zebra iris

Then there are the perennials. My garden comes on a little later than most and the buds of the fragrant variegated Zebra iris are just opening. They will smell like grape Kool-aid when the sun allows the scent to develop.

Last year Chris and Rick Moran over at Brook Lomond Iris Farm gave me a couple Zebra rhizomes and they are growing quite nicely. Every year the Moran?s have a tall bearded iris show and sale over two weekends in the spring. This May 13th and 14th is the second weekend and the show takes place at their garden located at 10310 California Drive in Ben Lomond. The Iris Farm is educational, too, as the Moran?s are well-versed in organic gardening practices.

Chris told me a scented flower story about an iris called Scented Nutmeg. Seems that when the long awaited flower finally opened she bent down and smelled nothing. The blue flower was pretty anyway. Later when working out in the garden she smelled cookies baking. As none of the neighbors were home at the time she was puzzled. Sitting down the smell hit her again and she realized she was right next to the Scented Nutmeg. They just needed the sun to warm up the flower to give off the scent.

Philadelphus lewisii at Felton Covered Bridge

Other fragrant plants include California natives Philadelphus lewisii or Wild Mock Orange. Calycanthus occidentals or Spice Bush is native to our Central and Northern California mountains. Their fragrant burgundy flowers smell like red wine. Ribes viburnifolium, carpenteria californica and rosa californica are mildly scented, too.

In spring there may be nothing quite as spectacular as a wisteria vine, loaded with fragrant purple, pink, blue or white flower clusters, covering an arbor or pergola. Pink jasmine is another vigorous vine with intensely fragrant flowers as is Evergreen Clematis.

Nemesia and Dianthus

I can’t leave out the old fashion border carnation or dianthus. Their clove-scented flowers are born in profusion making them a nice addition to the mixed flower border and containers.

The list goes on and includes scented plants such as nemesia, wallflower, Japanese snowbell, hosta, coneflower, daphne, vitex, viburnum, Oriental lily, gardenia, nicotiana, phlox, rose, sweet pea, hyacinth, lilac, flowering crabapple, heliotrope, lavender, sweet alyssum, peony, moon flower, southern magnolia.

Flowering Trees & Shrubs of Early Spring

Outside my window the Blireiana flowering plum is covered with dark pink, double blossoms. It’s one of my favorite early spring blooming trees with a sweet fragrance strong enough to scent the garden. We look forward to the earliest flowers of the new season knowing that winter will soon be over. Spring officially begins on March 20th.

Old fashioned shrubs like flowering quince and forsythia figure prominently in many old gardens because they are tough plants able to survive neglect and still look beautiful.

Forsythia ‘Kolgold’

The bare stems of forsythia are completely covered with deep golden-yellow flowers in late winter and early spring and become the focal point of the landscape when in full bloom. The showy stems of this easy care shrub are great for cutting. Forsythias are native to eastern Asia but a chance discovery in Germany by a grower who specialized in breeding for the cut flower industry led to the especially vivid variety ?Kolgold? in the 1800’s. Forsythia has long been used in Chinese medicine. The flower petals contain powerful bacteria-fighting properties which make it an important dressing.

Flowering quince

Flowering quince is another old garden staple providing early color. They are easy to care for and nearly indestructible in almost any soil that is well drained and not overly fertile. Once established quince is a very drought tolerant plant and their spiny branches make them an excellent choice for hedges, screening or as a security barrier. There are red, pink, orange and white flowering varieties. The Toyo Nishiki cultivar even has pink, white and solid red flowers all on the same branch.

Clivia miniata

What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters that emerge from between dark green, strappy leaves. Even in dark shade they will bloom and brighten the winter garden although they would do fine in morning sun. If you have a north facing window you can grow them as houseplants. Clivia are hardy to several degrees below freezing but mine, under an overhang, have survived temps of 23 degrees without damage. Clivia breeders have produced gold and peach colored flowers also but I still like the standard orange ones.

A beautiful vine that blooms in winter is hardenbergia ‘Happy

Hardenbergia ‘Happy Wanderer’

Wanderer’. In the pea family, this evergreen vine looks like a small wisteria when in bloom. Pinkish-purple flowers cascade in clusters on twining stems that reach 12-16 feet long. It requires little water once established and is hardy to about 23 degrees. If you have an older, tangled plant you can rejuvenate it with hard pruning in early spring after flowering. Never prune in late summer or fall because you will cut off the wood that is going to bloom the following winter.

The last plant I couldn’t live without is Fragrant Sarcococca. The tiny white flowers of this plant are easily overlooked but you can’t miss their scent. I have one near the front door that greets me with that vanilla fragrance every time I walk in or out. The flowers are followed by a bright red fruit. Sweet Box forms a natural espalier against a wall and if you have a problem spot in deep dry shade where other plants won?t grow give this plant a try. They are easy to grow, deer resistant and trouble free.
