How to Create a Sense of Depth and Height in Your Garden – Also a Word about Raised Beds

Jacki Kellum Garden 2022

I subscribe to the gardening principle that gardens should be layered, with taller plants in the back, medium-sized plants in front of those, and the shortest plants in front of the other two layers. The magazine Fine Gardening provided the following graphic to explain that tenet:

Fine Gardening September and October Issue 2021

in 2022, I was gardening in the Ozark Mountains, but in 2023, I moved to my current home in Water Valley, Mississippi. I spent most of my first year here creating a raised garden area above a lawn that was gnarled by a covering of  Bermuda grass. I have already ordered several perennials that should arrive here in early spring. As usual, I’ll place the plants in ascending height. Following is a list of those plants from shortest to tallest:

Phlox Creeping Snowflake (Phlox subulata)

Height: 2-4″ tall

I have created brick walkways in my garden area, and one of my first goals is to fill the space around and between the bricks with creeping low-growing plants. Last year, I placed some ajuga and low-growing sedum around the bricks, and this year, I am adding some creeping phlox there. Phlox is a native plant, a pollinator, and it is evergreen.  It blooms for about 4 weeks during mid to late spring.

“Creeping phlox is a fast-spreading and hardy ground cover that has been used by gardeners to naturally suppress weeds in their garden or landscape. The secret is in the soil. It’s a carpet of flowers chokes out weeds by stretching underground through the soil.”  Great Garden Plants

During the early fall, I added several Goldstrums. Black=Eyed Susan is the Queen of my Autumn Gardens. I love to see how she dances with the Purple Fountain Grass and the Purple Asters that I also plant for fall.

Backtracking to the discussion of raised beds, look at the same spot months earlier:
My garden April 15, 2021, I had added cardboard to help slow the grass and weeds. On top of the cardboard, I added garden soil one bag at a time. I have approached gardening this way for many years.
By the way, Purple Fountain Grass is not a perennial in my area, but I always grow it in my garden. I love how it looks during the autumn. It is also a way to add focal areas and height.

Height: 36-48″ tall
Because of its airy and arching “fountain” habit, I add Purple Fountain Grass next to my Black-Eyed Susans. In places, I like a bit of irregularity in height, but overall, my garden ascends from shorter plants in the front to taller plants in the back.

Now that I have shown you the plants I am adding this fall, allow me to add that I also like to add other vertical features throughout my garden plantings, too. I like the way that these vertical spots add variety to what otherwise might become too much the same.

Better Homes and Gardens has a great online site that offers all sorts of garden tips and free garden plans. In regards to adding height in gardens, they comment about how one featured couple “… group attractive containers on a plant stand to make use of vertical growing space in their small Southern California garden. The effect has a big impact without taking up a lot of ground”

Jacki Kellum Garden

In the above photo, you see that I have staggered the heights of my containers by placing them on varying heights of other containers. I did not stick with this plan, but you do see how I had intended to create incremental heights with pots or containers.

Jacki Kellum Garden with Waterfall – 2022

Ultimately, I moved the waterfall away from the wall and created height around the waterfall/pond area in other ways. I used raised beds of incremental heights, and I also used tall plants at the focal point of the waterfall to add higher spots in my garden.

Better Homes and Gardens adds:

“Here’s a tip: You can do the same thing by displaying your favorite collections on vertical surfaces such as walls or fences.”

Zepherine Drouhin Rose is a thorn-free and disease-free rose. Although it has no noticeable fragrance, I often use this rose to add height to various spots in my garden.

Jacki Kellum Garden 2022

In the above photo, you see that I have used a small water fountain to add height. I have used King Tut papyrus to increase the impact. King Tut is a papyrus and it is not an actual grass, but I do use grasses to add height to my garden, too.

Jacki Kellum Garden 2022

The lighter green grass is lemon grass, and the burgundy is purple fountain grass. The pink is an Arct Fox foxglove. It is much shorter than the regular foxglove which grows earlier in the season, but it is still taller than most garden plants, and I use taller plants to add height and variety in my garden, too.

If you look closely, you will see that lemon grass looks very much like the leaves or blades of daylilies. I grow daylilies both for that greenery and for their blossoms.

In the above photo, you see my cannas from behind. I plant cannas at the back of my garden. They create a natural wall against which to set the plants in front of it. I also have Russian sage, pineapple sage, and hollyhocks back here, but none of them are blooming now. Note: The greenery of plants is almost as valuable in the garden as the plants are after they have bloomed.

I grow clematis vines to add another source of height.

Over and again. I will say that I am a true cottage gardener, and the cottage gardeners of old were peasants who had very small gardening spaces. Utilizing vertical spaces was essential to the success of peasant gardens.
