How to Choose Sensory Plants for Raised Planters (While Avoiding Costly Eye Candy)

When shopping at a garden centre, it’s easy to be seduced and overwhelmed by delectable eye candy. So here are a few guidelines for choosing sensory plant varieties for raised planters. You’ll offer your garden visitors a wide range of sensory experiences, make the most of your money and time and avoid costly mistakes (aka invasive plants).

Print out the sensory plant list and bring it with you. Bring a snack. If plant toxicity is a concern, bring a reference with you (see below). Most garden centres and nurseries have a bathroom available for customer use.

Give yourself lots of time and relax into the sensory pleasure and fun of choosing plants. If your time is limited, focus on choosing plants for one raised planter so you can make sure the colours, textures and sizes go well together, and come back for the rest another time. Your new purchases will be healthier if they get planted soon, and there will be more to see at the garden centre next time.

6 packs of Johnny Jump UpsLook beyond those first LARGE gorgeously blooming plants you see. Seedlings in six packs cost less and don’t take long to catch up. Ditto for herbs and perennials in smaller pots. Better to drop a bundle on a thriller centrepiece or two that provide instant and long-term impact.

 


 

 

 

 

Look at plant labels for the information you need. Ask specific questions. Sometimes a staff person will save you time by showing you the best choices in stock for your situation.

Read plant labels before buying

You’re looking for plants that are:

  • delightfully sensory in two or more ways
  • polite about sharing space with other plants
  • the right size (maximum plant height of twice the planter soil depth is a useful rule of thumb)
  • thrillers, spillers & fillers for a layered effect
  • interesting throughout the seasons
  • contrasting or complementary colour palette

lambs ear plantSensory plants have to pay the rent for the space they take up. It’s a waste of space if they’re just pretty to look at. The plants I’ve selected have other qualities too: enticing to touch; fragrant leaves or flowers; edible parts; and/or attractive to birds, butterflies and bees. Most have a long blooming season or other interesting features.

varieties of mintPlants in raised planters must be polite about sharing space. Mint is a valuable sensory plant that insists on taking over, so plant it alone in its own container. Any plant that says ‘spreads quickly’ (or words to that effect) should be avoided for raised planters. Like Moroccan mint and golden oregano, they may be desirable in their own container. It’s easy to ignore this recommendation when you have the cutest little plant in hand that looks so innocent. Be strong and resist! Ivy, Houttuynia, gooseneck loosestrife, Lamium, Vinca, bamboo and some Campanulas are culprits I’ve dealt with, and there are plenty of others. 

pinksChoose scented plants that require you to rub and sniff the leaves, or to put your nose close to the flower. Avoid scented flowers that waft on the breeze, like Stargazer lilies. They can be overwhelming to some people, as well as overwhelm other scented plants.

Foliage colours, textures and shapesAs your cart fills up, consider how your plants will look growing together. Leaves always provide a longer season of interest than flowers, so choose a variety of foliage colours. For example: black mondo grass, and silver, yellow, blue or reddish-leaved plants, as well as an assortment of green leaves. Also consider contrasting leaf shapes, sizes and textures.


Seasonal interest and bloom time are also important, but if you’re feeling overwhelmed at this point, rest assured that you can return to the garden centre to buy plants when your garden develops bald spots. You’ll be better able to choose by flower colour and scent at that point, anyway.

Plant toxicity is a concern in some therapeutic gardens. In any garden, it is unwise to grow toxic plants right next to edible plants. For instance, pods of fragrant sweet peas look just like edible pea pods, but they’re toxic. So designate one or more containers for edible plants, and other containers for ornamental plants. In the sensory plant list I included toxicity information for daffodils and choking hazard for cherry tomatoes to alert you to the dangers. To the best of my knowledge and resources (see below), the other plants I’ve selected are not toxic, but I make no guarantees. It’s invaluable to have a toxicity reference with you while you’re shopping.

With these shopping guidelines and the Sensory Plant List for Raised Planters in hand... with your nose and fingers twitching in anticipation of sensory delights... with your desire to buy now contained long enough to focus on what each plant label says... you're sure to make wise plant choices that you and your garden visitors will enjoy for months and years to come!

Paddling on Ocean Habitat near Naka Creek

I think of mammals sharing this watery world with me, moving sinuously through its depths and coming up for air; like the seal that turned my head yesterday with the sound of its breath. We looked at each other from our separate worlds of forested land and salty sea; so foreign to each other and yet closely related as mammals.
