Cultivating a Fragrance Garden
When we design our gardens we base our plant choices first of zone, bloom season, bloom color, and the eventual mature size. Secondarily we may consider if the plant has any fall/winter-seasonal interest, its foliage color, and whether it has any pest/deer resistance. Fragrance comes in dead last as a deciding factor and that is unfortunate.
The fragrant garden is one that enlivens all of our senses. Evoking memories and making new ones, a fragrant garden can transform you to another world is just a few seconds. A flower without a scent is an empty experience.
Fragrance is a very personal thing. Some plant scents may be heaven to you and hell to others. Smell first, before you buy. Just because a plant is known for its strong odor does not mean it is one you will enjoy. Marigolds and mums are flowers that often offend the nose, though they have their place in the garden too.
Place your favorite fragrant plants in locations where you will encounter them frequently such as by the entrance you use most to your home, near your sunroom, along garden pathways, in hanging plants on your porch, and outside your bedroom window.
Think also about when a plant is fragrant – both in season and time of day. Many scented flowers bloom in evening and are perfect for those who work all day outside the home. These include columbine, flowering tobacco, honeysuckle, evening primrose, and climbing hydrangea.
Lastly, examine how different plant scents intermingle. One flower may perfume a whole garden, while another may need experiencing by directly smelling it up close. From a pine tree to sage, you will want to situate your plants where their smell is experienced to best advantage.
Here is a partial lists of plants to lend fragrance to your garden:
- Basil
- Bee balm
- Bronze fennel
- Climbing hydrangea
- Daffodil
- Evening primrose
- Flowering tobacco
- Fothergilla
- Gardenia

For inspiration and more ideas, visit the fragrance gardens locally at Brookside Gardens, the US Botanic Garden, and the Norfolk Botanical Garden..
Happy Growing!

Spotlight Special: Climbing Hydrangea Firefly
Climbing Hydrangea Firefly (Hydrangea anomala subsp. petiolaris 'Firefly') is a new introduction discovered by Dan Benarcik in New England. (Dan is a horticulturist at Chanticleer in Wayne, PA, and was formerly Plant Collections Manager at Brookside Gardens in Wheaton, MD.)
Rare variegated foliage on a climbing vine for scaling trees, scrambling along fences, covering the garden floor, or even pruning into shrub form. Use to best advantage in climbing a single tall tree or covering an unsightly fence.
Each bright green leaf is neatly outlined in yellow, as summer progresses the gold margin turns to chartreuse. The fragrant, giant lacecap blooms of creamy-white cover the vine for many weeks. It is deciduous, but in winter the leaf loss reveals peeling cinnamon-brown bark.
Takes a year or two to establish in your garden, then Firefly will grow about two feet a year, creating long-lasting vertical color -- eventually reaching 25' high by 3-4' wide.
Hardy in zones 4-7. It flowers in late spring/early summer and thrives in sun/part shade. No pruning is necessary.
It is available in Park Seed's Fall 2007 catalog and is being produced for the reatil trade by plant wholesaler Spring Meadows.

July To-Do List
Here is our combined garden task list for July 15-August 15 compiled from the previous July 2005 and July 2006 issues:
- The heat of summer is here, time to start doing chores during early morning or evening. Take a break during the hottest parts of the day.
- Prune Wisteria.
- If your pond water gets low from prolonged drought, top it off with tap water and add a dechlorinator according to package instructions.
- Cut back spent common Daylily stalks.
- Pinch back any annuals that may be growing leggy.
- Divide and cut back bearded iris.
- Check your pond pump for debris and clean it out every few weeks.
- Weed.
- Cut off bottom, yellowed foilage on tomato plants.
- Stake and tie-up any tall-growing perennials such as phlox or delphiniums.
- Wash out birdbaths weekly with diluted bleach solution.
- Water thoroughly especially if you receive no rain for more than 5-7 days.
- Take cuttings from azaleas, boxwoods, and camellias to start new plants to share.
- Check your local garden center for mid-summer bargains.
- Hand pick Japanese Beetles or shake a branch over a bucket of dishwater. Early morning is a good time to catch them while they are still drowsy.
- Repot the houseplants you've moved outdoors for the summer.
- Pick blueberries at a local pick-your-own farm or visit a local farmer's market.
- Pinch back any straying strawberry runners.
- Deadhead perennials for a second flush of blooms later this summer.
- Thin out small trees and cut off any suckering branches growing from the bottom root ball.
- Inspect your garden for powdery mildew. If seen, prune back perennials to create needed circulation.
- Annuals are now hitting their peak. Keep them well-watered and add a little liquid fertilizer every few weeks to keep them going through September.
- Check your plants at night with a flashlight for any night-feeding insects like slugs. If you find slug damage, set out beer traps or Sluggo.
- Pinch back mums so they grow bushier and won't flower until autumn.
- Holding off on planting new trees and shrubs until the summer heat is past.
- Caulk and seal your outside walls to prevent insect entry into your home.
- Harvest regularly from your vegetable garden to prevent rot and waste.
- Put up a hammock or a garden bench to enjoy your views.
- Turn compost pile.
- Check out gardening books from your local library to read on vacation.
- Check for mosquito breeding grounds. Dump out any water that sits stagnant for more than three days.
- Add Mosquito Dunks to any standing water in your yard such as birdbath, downspouts, plant saucers, and gutters.
- Gather roses to enjoy indoors and make sure to make the cut just above a five-leaf unit.
Have a wonderful 2007 growing season!

Magazine Excerpt: Geraniums Galore by Kate Tyndall
My gardening life substantially improved when I discovered hardy geraniums. They are the worker bees of flowering plants and can be used to weave areas of the garden together or step forward to take a starring role.
These are not the flamboyant South Africans with their showy blooms and felted leaves that have traditionally been served up to generations of mothers by their spouses and offspring on Mother’s Day, but a large tribe of flowering perennials. The Mother’s Day geranium is a member of the Pelargonium genus, though both the pelargoniums (annuals) and true geraniums are branches of the same family, Geraniaceae.
As a lover of plants with handsome foliage, the hardy geraniums (commonly known as cranesbills for their beaked seedheads) have delighted me with their cut leaf form and chameleon’s way with color. As the weather turns cooler in the fall, the leaves of many geranium species will flush with tints of red, purple, and orange. These handsome plants flowering is just icing on the cake for me, but if bloom is the raison d’etre for your gardening efforts, perennial geraniums will delight you. Many of them have an extraordinarily long flowering time, and some are repeat bloomers.
Geraniums are not garden prima donnas. They thrive in all but boggy soils...
