Beyond Gardens · Horticultural Perspectives

In November 2020, I wrote about the planting on the Well Road roundabout between Douglas and Blackrock in Cork. It had been a delight that year, showing what could be achieved in an everyday public space with a change in approach.

Instead of several hundred Primulas being planted in springtime to be replaced with summer bedding, passers-by had been treated to a mixture of perennial plants, with Heleniums planted in blocks next to Coreopsis, Achillea and Geranium ‘Rozanne’, alongside Stipa ‘Pony Tails’, Salvia ‘Caradonna’ and Crocosmias.

The overall effect was one of colourful nonchalance, although looking more closely, you could see that quite a lot of thought and planning had gone into creating that “it just happened” look. By November, the colours had gone past their bright summer best, the planting had taken on muted autumnal tones, and the textures remained.

I finished that column wondering what would happen the following spring, whether the planting would be allowed to develop or be changed again. That question takes us beyond the appearance of one roundabout, because a good first summer is only the beginning of a public planting scheme.

The thought behind the planting matters

What impressed me was the way the plants worked together, their flowering seasons, shapes and textures giving the space more than a brief display of colour. It brought a smile to my face, and I wanted to acknowledge the people responsible for making that change.

Public planting can contribute to how we experience a place, while suitable flowers can provide food for pollinating insects. The All-Ireland Pollinator Plan’s guidance for councils provides practical ways to support pollinators on public land, including planting choices and changes in management.

The purpose still needs to be clear for each site, whether the priority is seasonal interest, pollinator food, shade, rainwater management or a combination of these. A flowering roundabout and a public garden where people can sit and spend time offer different opportunities, and the brief should recognise that.

The horticulture has to work from the beginning

Before a plant list is agreed, someone needs to establish what the soil is like, how water moves through it, how exposed the site is and how much room the plants will have. A plant that performs beautifully in one public space may struggle a short distance away.

On a roundabout, sightlines, access for maintenance and eventual plant height also matter. These are decisions for the horticultural and roads teams to resolve together, before the planting goes into the ground.

This is central to the From Why to How approach I am developing through Beyond Gardens, bringing horticultural judgement into the brief while there is still time to shape what can realistically be achieved.

Perennial planting changes the work, it does not remove it

Moving away from replacing an entire display twice a year can make sense, but perennial planting still needs people who understand how to care for it. Young plants need establishment care, weeds need managing, and the planting will change as some plants spread and others need dividing or replacing.

The question is who will do that work, when they will do it, and whether the time, knowledge and budget have been agreed. Those arrangements belong in the original proposal, rather than being left until the first problems appear.

It is crucial that public planting plays the role it can play, and that greening our public areas moves from the “wouldn’t it be nice” folder to the “essential” folder.

People need to understand what they are seeing

In that original column, I described how the bright summer colours had faded but the textures remained. To someone expecting every bed to be cleared and replanted for winter, standing stems and seedheads may look unfinished.

Explaining the purpose and seasonal appearance of the planting is part of the work, through suitable information, local communication and a maintenance team that understands the design. People should also have a way to raise concerns, because an explanation does not replace good care.

We should be able to show what the planting delivers

My Well Road column was an account of what I saw and enjoyed, rather than a measured assessment of costs, pollinator activity or other outcomes. Those are different kinds of evidence, and we should be clear about the distinction.

For a new scheme, useful records might include plant survival, gaps in flowering, maintenance time and the amount of replacement planting needed. Where a project is intended to deliver specific ecological or drainage outcomes, the relevant specialists should help decide what needs to be measured.

The assessment should suit the scale and purpose of the work, giving us enough information to improve the next project and explain what the investment has achieved. That is how individual schemes can contribute to better decisions about biodiversity and the places we live in.

A promising start deserves a plan for what follows

The Well Road planting caught my attention because it showed what thoughtful plant choice could bring to a familiar public space. I wanted to see that approach repeated in Cork and beyond, and that ambition remains.

To give public planting the best chance of succeeding, we need to consider the site, the plants, the care, the people affected and the intended outcomes together. The first summer gives us something to admire, the decisions made before and after it determine what follows.

This perspective develops observations first published in my Irish Examiner gardening column in November 2020. I was writing about planting I admired, rather than a scheme I designed.
