It is usually the intricate shape or fabulous color of a leaf which make us scramble over rocks or slither under bushes to get the perfect shot of fabulous foliage for you.
Yet there is another attribute that we often forget to mention – that of fragrance. The leaves of many trees, shrubs and perennials release a scent when brushed or bruised and while this may be impossible to capture in a juicy photograph these plants have something beyond their good looks to offer the designer and homeowner alike.
Of course not all garden aromas are desirable! One of my lecturers insists that boxwood smells like cat pee (!) and that Mexican orange blossom (Choisya ternata) is little better. I can’t say that I find them offensive but I certainly don’t use boxwood for its fragrance.
I am interested in leaves that have it all – good looks and a pleasant fragrance. As a bonus many of these plants are deer resistant and usually pest free. My design mantra is that gardens should be experienced and not just observed and that means involving all the senses not just sight. Let’s look for leaves that can be explored with the finger tips, taste buds and nose as well as having exceptional good looks! Here are a few of my favorites.
Incense cedar (Calocedrus decurrens)
This is an elegant slim conifer that typically grows 40-60′ tall yet only 8-10′ wide. Native to the western United States it is hardy to zone 5 yet is not found in many home gardens. Although not a true cedar it does have a cedar-like fragrance both from the crushed foliage and the resin. Where privacy is needed this may be a better choice than the ubiquitous arborvitae. It also keeps a healthy dark green color throughout the year.
Goldcrest Monterey cypress (Cupressus macrocarpa ‘Goldcrest’)
Bright chartreuse foliage makes this slender conifer an easy winner for landscapes and containers but what makes it extra-special is the heady citrus scent that is released when the foliage is touched. Pair this with deep purple spurge (Euphorbia hyb.) for a bold backdrop to orange foliage and flowers. Or keep a crisp contemporary look by adding silver and white.
This dwarf beauty is hardy in zones 7-10 where it will grow 6-8′ tall and 2′ wide.
Lavender sp. (Lavandula)
When I worked in a nursery I would find every excuse to walk by the lavender display and casually brush my fingers through the highly aromatic foliage! Somehow that heady fragrance would make me slow down, breathe in deeply and relax – which is why of course it is so popular as an essential oil in aromatherapy.
There are many species, hybrids and colors of both flowers and foliage as well as variability in the hardiness. They all need full sun and exceptionally well drained soil – ask at your local independent garden center for advice on those best suited to your area. Is any garden really complete without at least one lavender plant?
Lavender cotton (Santolina chamaecyparissus)
Tough, evergreen, deer resistant and drought tolerant – four reasons to look for this silvery-grey leaved shrub. Yellow button flowers in summer are a bonus. It may need whacking back every couple of years to stop it getting too leggy but if like me you have some areas that need bullet proof plants check this out.
The fragrance is hard to describe – somewhat medicinal but not in a bad way!
At 1-3′ tall and wide it can be used to edge herb gardens and pathways or set as an informal evergreen groundcover. See it paired with Blue Shag pine at the start of this post and read about the beautiful combo (“Easy on the Eyes’) on pages 62-63 of Fine Foliage
Last summer I discovered its relative Lemon Fizz lavender cotton (Santolina virens ‘Lemon Fizz’). This was an outstanding tender perennial with bright chartreuse foliage forming tidy cushions and smelling of pine. I’m definitely getting more next year.
Catmint (Nepeta sp.)
My first introduction to this herbaceous perennial was the variety Six Hills Giant which I allowed to scramble at the base of climbing roses in my English garden. Soft grey leaves were topped with blue summer flowers all of which exuded a wonderful herbal smell.
Today I favor Walker’s Low which despite its name is not a dwarf variety but rather takes its name from of the garden where it was originally found. Although it is less straggly than Six Hills Giant I still shear it back by half in early summer – within two weeks it bounces back into a tidy cushion.
Hyssop (Agastache sp.)
The foliage of this perennial is somewhat reminiscent of catmint although the habit is typically more upright. There are many varieties available today with heights ranging from the dwarf Apricot Sprite to the much taller Blue Fortune. Flower colors range from blue to orange and pink and they all attract hummingbirds which get positively giddy with excitement. Even without the flowers this is an easy plant to enjoy in the garden for the drought tolerant, deer resistant foliage alone. I have grown Apricot Sprite as the centerpiece of a succulent hanging basket, as well as in containers and the garden.
Curry plant (Helichrysum italicum) – while it does smell like curry it is not recommended for eating and does not in fact taste like curry at all. At first glance you might mistake this for lavender since the foliage is almost identical but the small yellow flowers are quite different.
I love the texture of this perennial (hardy in zones 8-11) and it is fun to include in designs as a talking point for garden visitors.
- Rosemary, sage, mint, thyme and lemon verbena all assault the senses with their aromatic leaves as do so many other culinary herbs
- Wormwood (Artemisia sp.) comes in many shapes and sizes some better behaved than others! My personal favorite is Silver Mound (Artemisia schmidtiana ‘Silver Mound’) featured in our book (Purple Waves, p52) This is another plant whose fragrance is rather hard to describe – somewhat musky yet medicinal. Not unpleasant yet perhaps not one you would want in great quantities.
- Scented geraniums and citronella for keeping those pesky mosquitoes away!
