10 Bad-Smelling Flowers and Their Use in Landscaping

Sometimes, Even Blossoms Stink

Your first impression may be that it borders on oxymoron to speak of bad-smelling flowers. Isn't the blossom symbolic of fine fragrance? Rose blossoms certainly are, for which we have such proverbial expressions as:

  • "​Stop to smell the roses."
  • "He came up smelling like roses."

Be that as it may, pointing out that a plant has bad-smelling flowers is not exactly a man-bites-dog story. The phenomenon occurs a bit more often than you might think. This is true even if we exclude those strong-scented blooms, such as Easter lilies, over which people are divided, some listing them among the fragrant flowers, others finding the odor offensive.

While many bad-smelling flowers dwell in the warmer regions of the globe, these are flowers that gardeners in the North are more likely to encounter. The examples listed below may not stink as badly as the notoriously foul-scented "corpse plant" (Amorphophallus titanum) of Sumatra or its somewhat smaller relative, Amorphophallus konjac (the snake lily), but you're much more likely to have dealings with them in everyday life.

    Crown Imperial

    The blossoms of spring hold a special place in our hearts, an observation that is doubly true for those who garden in the North and must endure long, harsh winters. A subset of spring-bloomers remarkable in its diversity is the group are known as the spring bulb plants. Consider, for example, just the range in height from the tiny snowdrops to the rather imposing crown imperial (Fritillaria imperialis).

    Crown imperial also contrasts nicely with another of its bulbous compatriots: hyacinth. But here, the contrast pertains to scent. Hyacinth wafts a sweet perfume on the spring breezes, but crown imperial gives off a skunk scent. Bad-smelling flowers or not, though, this plant should have a place in your landscaping. Its orange flowers make a strong statement in the spring garden.

    Yellow Alyssum

    Your first thought when you hear "alyssum" may be of a white annual used as a bedding plant, sweet alyssum. The "sweet" in that plant's name is there for a reason: it is sweet-scented.

    But the yellow alyssum is a yellow-bloomed perennial with bad-smelling flowers. You can also use it in landscaping as a ground cover.

    Candytuft blooms at about the same time (mid-spring to late-spring in USDA zone 5) as yellow alyssum and its use in landscaping is also as a ground cover. With a name that has "candy" in it, you might assume that its blossoms have a sweet scent, but you would be wrong. Candytuft does not stink to high heaven; it's just that sticking your nose into them to take a sniff will likely end up a mildly unpleasant experience for you.

    But scent aside, this is another spring-blooming plant that one should not be without. Up close, you can enjoy gazing into the arrangement of its petals' blossoms; from a distance, a massed planting of it will gain the attention of even the most unobservant.

    Bradford Pear Trees

    So far, the examples listed, despite bearing bad-smelling flowers, are plants that are nonetheless generally recommended for use in your landscaping. Bradford pear trees, however, are not.

    But it is not their bad-smelling flowers that make Bradford pear trees a landscaping liability. Rather, it is the brittleness of their branches that is their main drawback. These specimen plants seem to break at the mere hint of a wind storm.

    Incidentally, Bradford pear trees are one of many examples of plants with white blossoms that bear bad-smelling flowers. The color white seems to be one of the worst offenders in this regard. Have you ever noticed that many white-flowered plants attack the nose with a cloying scent?

    Hawthorn Trees

    One associates certain plants with certain places. For example, a friend vacations every spring in Maine, USA, carefully observing what plants the locals use in their landscaping. If he has been sufficiently inspired, he may look up the plant at a nursery, bring it home with him and plant it in his yard. Forever afterward, he will associate it with Maine.

    Such is the case with hawthorn trees. He saw one in bloom during his Maine travels in early June one year, in the parking lot of a convenience store (of all places). He decided that he had to have one. This member of the Rose family is a classic for its berries and, yes, its thorns. Its blossoms, however, while attractive to the eye, are not exactly scented like roses.

    Do you endeavor to landscape for the four seasons, so that there is something to catch the eye regardless of the time of year? If so, then mountain ash trees may be of use in your landscaping: They possess three noteworthy attributes, spread across three seasons.

    But the bad-smelling flowers they produce in spring are "for your eyes only" (keep your nose away!).

    Trillium is a wildflower. Although some gardeners purchase it at specialty nurseries for use in their landscaping, you are more likely to encounter this plant in the woods. Indeed, if you were to use this plant in landscaping, it would be most effective in woodland gardens, since it is a shade plant. The Trillium with which people are most familiar is native to North America.

    Luckily, there's little chance of catching a whiff of its bad-smelling flowers while going about your business in the yard. As a short plant, you would have to go out of your way for your nose to get anywhere near its blossoms.

    Butterfly Bush

    Perhaps only some butterfly bush shrubs produce really bad-smelling flowers, but the plants are generally grown for something other than their fragrance. Fortunately, butterflies find them plenty redolent: Buddleia is a major magnet for butterflies.

    Butterfly magnet or not, butterfly bush cannot be recommended indiscriminately for use in your landscaping. This shrub can be an invasive plant in some regions. Find out how it behaves in your region before falling in love with it.

    Tree of Heaven

    Tree of heaven (Ailanthus altissima) is unequivocally invasive, and its blossoms are unequivocally stinky. No use in your landscaping for this one, folks. But a picture of it is included here for identification purposes, in case you've spotted this Chinese native somewhere and wondered, "What the heck is that?"

    Sometimes termed one of the "junk trees," you are likely to encounter tree of heaven in urban areas. It is aggressive enough to flourish in places abdicated by the more delicate members of the horticultural world. Pollution doesn't touch it.

    Dragon Lily

    Although it looks like it belongs on an island bathed by tropical waters, dragon lily (Dracunculus vulgaris) is cold-hardy to planting zone 5. There's a similar plant named "snake lily" (Amorphophallus konjac), but it is hardy only to zone 8.

    Among the other common names for this bad-smelling flower are dragonwort, dragon arum and black dragon. You've probably noticed by now all the "dragon" references. Even the Latin genus name contains one, translating as "little dragon." So what's that all about?

    Well, this is one of those plants that features a spadix inside a spathe, another example being Jack-in-the-pulpit. In the latter case, the spadix is where they get the "Jack" from. In the case of dragon lily, the spadix is imagined to be a dragon. Even if you don't buy that, you have to admit that the plant is sufficiently weird-looking to merit dragon references, one way or another.

    Of the 10 bad-smelling flowers here, this native of the Balkans and parts of the Mediterranean would perhaps be deemed the most likely candidate for such a list if you are a plant aficionado and recognize it as a type of arum. The Arum genus is infamous for having some real stinkers in its ranks.
