How to Design an Allergy-Friendly Mediterranean Garden

Sometimes, life has an excellent sense of humour.
A few weeks ago, after another spring of itchy eyes, sneezing and antihistamines,
I finally visited an allergist.
The results came back almost immediately.
I'm highly allergic to grasses.
I couldn't stop laughing.
Because if you've followed my work for a while, you'll know that one of my favourite plants to design with is Stipa tenuissima. I love the way it catches the light, dances with the wind and softens Mediterranean landscapes. It has become one of the plants I recommend most often.
Apparently, my immune system completely disagrees.
A Conversation That Changed My Perspective
As often happens, one conversation led to another.
When I mentioned that I was a landscape designer, Dr. Renato Ariano smiled and introduced me to a concept I had never seriously considered before:
Allergy-friendly gardens.
Although I spend a great deal of time thinking about biodiversity, water conservation, soil regeneration and climate resilience, I had never really considered allergies as a design parameter.
Yet it suddenly seemed obvious.
A garden should not only be beautiful.
It should also make people feel well.
Gardens Are Changing Too
During our discussion, Dr. Ariano explained how climate change is also transforming our relationship with pollen.
Warmer temperatures, rising CO₂ concentrations and changing weather patterns are extending pollen seasons in many regions. Some plants flower earlier, others produce larger quantities of pollen, and allergy seasons are becoming longer and more intense for millions of people.
As designers, we often think about creating resilient landscapes.
Perhaps resilience should also include the people living inside them.
What Is an Allergy-Friendly Garden?
An allergy-friendly garden isn't a sterile garden.
Nor is it a garden without biodiversity.
It simply means understanding which plants produce large amounts of airborne pollen and making thoughtful design decisions.
Many of the most allergenic species are wind-pollinated plants. Instead of relying on insects, they release enormous quantities of lightweight pollen into the atmosphere.
Among the most allergenic groups are:
ornamental and wild grasses (Poaceae)
cypress and other Cupressaceae
olive trees
birch, alder and hazel
Parietaria, often growing on Mediterranean stone walls
ragweed (Ambrosia)
None of these plants are "bad."
Many are ecologically valuable and belong perfectly
in Mediterranean landscapes.
The real question is where we plant them.
Large masses of highly allergenic grasses immediately beside a terrace or bedroom window may not be the best choice for someone who suffers from seasonal allergies.
Good landscape design has always been about understanding context.
Perhaps allergies are simply another layer of that context.
Learning Something New
One of the things I love most about landscape design is that it constantly evolves.
Every site teaches something.
Every client teaches something.
Sometimes, even your own immune system becomes a teacher.
Meeting Dr. Renato Ariano reminded me that gardens are not only about beauty, biodiversity and resilience—they are also about the well-being of the people who experience them.
Because if we truly want people to reconnect with nature, nature first needs to become a place where they can breathe freely.
The more comfortable people feel outdoors,
the stronger their relationship with the living world becomes.
A Resource Worth Exploring
This conversation also introduced me to the remarkable work Dr. Ariano has developed over many years.
Through his website, Pollini e Allergia, he provides regional pollen forecasts, flowering calendars, scientific information about allergenic plants and practical advice for allergy sufferers.
Whether you're a gardener, a landscape designer or simply someone who struggles with seasonal allergies, it's an incredibly valuable resource.
I know I'll be using it much more often from now on.
What's Next?
Will I stop planting Stipa tenuissima?
Probably not.
Instead, I've decided to begin allergen immunotherapy (desensitisation).
Years ago, I followed the same treatment for dust mite allergies, and it genuinely changed my life. It taught me that our immune system can learn and adapt.
I still believe Stipa is one of the most beautiful grasses in Mediterranean landscapes.
But this experience has opened a new chapter in my own research.
Over the coming months, I'd like to explore allergy-conscious planting in much greater depth and better understand how landscape design can contribute not only to biodiversity and climate resilience, but also to human health.
Perhaps the gardens of tomorrow won't simply be more sustainable.
Perhaps they'll also help us breathe a little easier.
Special thanks to Dr. Renato Ariano for introducing me to the fascinating concept of allergy-friendly landscape design and for reminding me that the future of gardening isn't only about biodiversity and climate resilience—it is also about designing landscapes where people can truly feel well.
