Establishing the Middle Rhythm
This phase of the long border has been less about adding plants and more about understanding behaviour — how each plant actually moves, leans, competes, and cooperates once it’s in the ground.
The border runs broadly west to east, which matters. Light moves across the planting rather than sitting heavily on one side. That single fact resolves many of the theoretical shading problems you see discussed in books. Here, competition is dynamic, not fixed.
The back of the border is now structurally resolved (Buddlejas, Sambucus, Hydrangea, Fuchsia). What remained was getting the middle and front layers to speak clearly, without overcrowding or visual noise.

The Baby Joe-Pye Question
Originally, I considered using regular Joe-Pye weed at the back, with Baby Joe-Pye in front — a classic tall-to-short meadow approach.
But regular Joe-Pye is a brute. Beautiful, yes, but dominant. In a border already anchored by shrubs, it would tip the balance from structured naturalism into constant containment.
Baby Joe-Pye, on the other hand, is civilised.
-
Upright, but not towering
-
Pollinator-rich without being invasive
-
Repeatable, rather than monopolising
That led to a realisation:
I don’t need two species to create depth — I can create it through management.
Using the Chelsea Chop as a Design Tool
The Chelsea chop is often explained as a blunt instrument: cut everything, make plants shorter. That’s not how it’s being used here.
Instead:
-
Front Baby Joe-Pye plants will be Chelsea-chopped
-
Back Baby Joe-Pye plants will be left untouched
Same plant. Two roles.
The effect:
-
Front plants become shorter, bushier, and flower slightly later
-
Back plants remain taller, airier, and flower earlier
Visually, this mimics the effect of using both dwarf and full-sized Joe-Pye — without introducing a second scale that might clash later.
This feels like a more honest way of gardening: working with the plant rather than importing solutions.
Middle Layer: Final Composition
From left to right, the middle layer now reads as:
-
Erigeron — soft, informal, a gentle entry point
-
Geum ‘Mrs J Bradshaw’ — early heat and momentum
-
Baby Joe-Pye weed — vertical lift begins
-
Yellow Achillea — flat plates to calm the eye
Devil’s-bit scabious — wiry, upright, late-flowering, and utterly appropriate
-
Echinacea ‘Magnus’ — structural authority
-
Seed-grown Dahlias — variation and play
-
Child of ‘Verrone’s Obsidian’ — dark foliage pivot
-
Baby Joe-Pye weed (repeat) — rhythm, not symmetry
-
Dahlia ‘Sunshine’ — a yellow reset
-
Russian sage ‘Little Spire’ — haze and release

Front Layer: Holding the Line
The front edge is deliberately restrained. It isn’t where drama happens — it’s where the eye rests.
From left to right:
-
Erigeron
-
Fuchsia-toned Dahlias
-
Catmint ‘Six Hills Giant’
-
Dahlia ‘Tam Tam’
-
Eryngium ‘Blue Victory’
-
Catmint ‘Six Hills Giant’ (repeat)
-
Veronica spicata ‘Ulster Blue Dwarf’
The repetition of catmint is intentional. It’s the visual glue. Everything else is allowed to spike, blaze, or shimmer because the edge stays calm.

A Note on Control
I’m not worried about future spacing issues.
I own secateurs.
I own bypass loppers.
This border isn’t precious — it’s managed.
Plants are allowed to express themselves, but not to rewrite the design. Pruning here isn’t corrective; it’s editorial.
Closing Thought
What this process has reinforced is that good borders aren’t built by adding more plants, but by understanding fewer plants more deeply.
Baby Joe-Pye taught me that.
