Border Control: Gardening by David Wheeler

Blog | By ​David Wheeler | Aug 25, 2023

Call it May Madness if you like. A hare seen spiralling around an adjacent

field seemed similarly afflicted, as giant machines made silage, disturbing its equilibrium and, possibly, nearby nest.

My madness was of a different cast – the making of long herbaceous borders which I know full well someone else will have to maintain. Despite chronic back pain since major spinal surgery in 2018 and a life-changing cancer op just before Christmas last year (and trying to forget I’m approaching my ninth decade), I remain an incurable garden-maker – a creator, not a curator.

Hence the new borders – 56ft of them, seven feet deep.

May Day proved a timely moment to lift the turf. The overall length is broken in the middle to form a grass path into the newly planted apple orchard. And each half has a central break to accommodate a south-facing bench – sitting awhile now being increasingly important.

The design makes four rectangular beds – a less daunting prospect than one unforgiving, lengthy monster. I have had two of them roughly dug, ahead of being turned to a fine tilth after an initial weeding. The other two are subject to a no-dig regime, in an unscientific attempt to gauge the pros and cons of both methods. For height (unpruned, they’ll tower above my now round-shouldered six feet), I have planted two strong-growing, upright roses – Rosa moyseii ‘Geranium’ and its equally delightful kin ‘Highdownensis’. As the borders overlook a nascent collection of Japanese maples, chosen for their spectacular autumn foliage, the roses were selected more for their conspicuous late-season hips than for their early-summer flowers.

But the main reason for the borders is to billet my Siberian irises, hardy, easy- going, reliable, floriferous, variously- blue-shaded (other colours are available), clump-forming herbaceous plants which give of their best in late May and June. They like damp ground, which south- west Wales bestows freely. Usefully, their flower stems (upwards of three foot in some varieties) are taller than their leaves.

creamy ‘Chartreuse Bounty’, chalky- white ‘Gull’s Wing’ and the 1970s-bred, bicoloured ‘Butter and Sugar’.

To avoid the dangers of monocropping, I must introduce other plants to interweave among the irises and to provide colour and interest, once these beauties have retired.

Sidalceas are a new pursuit and we reckon we have just the right (moisture- retentive) soil for the larger types of lobelia – scarlet L cardinalis and guardsman-red L tupa, alongside the butterfly favourite, ‘Starship Blue’.

These summer bloomers will fill the gap nicely until the fabulous array of symphyotrichums (asters to you and me) take over. Stay tuned.
