Sensory Gardens For Dementia: Benefits & Design Ideas | Aria Care

Designed to appeal to as many senses as possible, a sensory garden can be a very rewarding place to spend time. They’re far more than a beautiful space, sensory gardens are designed specifically for the individuals who will use them. For example, if building a sensory space for a school you will want to encourage curiosity and touch, through lots of bright colours, smells, engaging textures and interactive elements. Children with special educational needs will particularly benefit from environments that allow them to explore using multiple senses.  

In a healthcare setting such as ours, sensory planting supports the wellbeing of residents, particularly those living with dementia. By engaging all five senses gently and purposefully, sensory gardens can spark happy memories and comforting nostalgic feelings, encourage independence, and create joyous times. 

Across Aria Care communities, our sensory gardens are built with insight, compassion, and collaboration, always shaped by the people who will enjoy them. Below, we explore how to design a sensory garden for dementia, why they matter, and the practical features that make them truly supportive. 

What Is a Sensory Garden?

A sensory garden is an outdoor space designed to stimulate the senses through scent, colour, texture, sound and taste. For people living with dementia, these spaces can: 

  • Promote calmness and reduce anxiety
  • Encourage gentle movement and outdoor activity
  • Spark autobiographical memories
  • Support conversation and social interaction
  • Offer comfort through familiar scents and textures
  • Provide opportunities for independence, purpose and choice 

When designed thoughtfully, a sensory garden becomes a reassuring place to explore, offering meaningful moments for residents, families and teams to share together. 

Why Sensory Gardens Support People Living with Dementia

For many people living with dementia, sensory experiences remain deeply rooted. This is why a simple scent, the rustle of grasses, or the warmth of sunlight can create moments of clarity and emotional connection.
Sensory gardens support: 

Emotional Wellbeing

Calming scents, gentle sounds and familiar plants help reduce feelings of agitation and support a settled mood.

Memory Recall

Familiar aromas, colours or plants can trigger memories and stories, often unlocking experiences that may feel harder to access indoors.

Identity and Independence

Gardens provide an environment where people can explore freely and participate in meaningful activities, from watering plants to picking herbs, helping them maintain a sense of self. 

Connection

Gardens encourage families, residents and care teams to spend unhurried time together, supporting natural conversation and companionship. 

How To Create A Sensory Garden – The Core Principles

1. Safety and Accessibility

A supportive sensory garden must offer freedom within safe boundaries. Key considerations include: 

  • Clear, even pathways: Wide, smooth, clutter-free paths help people navigate confidently and support gentle physical activity.
  • Non-slip surfaces: Essential in all weather conditions.
  • Soft boundaries: Fencing or natural barriers offer reassurance and reduce the risk of disorientation.
  • Non-toxic planting: Ensures residents can explore with confidence and touch plants safely. 

Erik Cortez, Clinical Deputy Manager at Cedar View Care Centre, explains: 

“When designing a sensory garden, particularly for individuals with dementia, safety is paramount. Ensuring clear, weed-free pathways is crucial… Implementing non-toxic plants, clear signage, and secure boundaries also comprised vital aspects of our safety considerations.” 

2. Sensory Stimulation Through Plants and Features

A garden designed for sensory engagement should feel vibrant, comforting and varied. To achieve this, consider: 

Aromas 
Lavender, mint, rosemary, thyme, jasmine and lemon balm can evoke memories, promote relaxation and invite exploration. 

Textures 
Plants such as lamb’s ear, ornamental grasses, ferns and soft herbs encourage gentle touch. 

Visual interest 
Use contrasting colours, seasonal flowers, and varying heights to support visual stimulation without overwhelming the senses. 

Sound 
Wind chimes, rustling grasses or soft water features can create a calming atmosphere and support orientation. 

Taste 
Edible herbs, berries and salad leaves offer curiosity, flavour and seasonal connection. 

3. Comfort and Rest

People should feel able to pause, rest and enjoy the space at their own pace. 

  • Comfortable seating: Armrests support safe sitting, standing and independence.
  • Shade and shelter: Pergolas, umbrellas and trees create welcoming spots throughout the year. 
  • Natural privacy: Thoughtful planting can create gentle, secure-feeling spaces. 

4. Activities That Encourage Purpose and Joy 

A sensory garden should invite participation in ways that feel natural and enjoyable. 

  • Raised planters: Ideal for people who love gardening but may prefer a supported height.
  • Wildlife features: Bird feeders and pollinator-friendly plants offer simple, joyful points of interest.
  • Interactive art: Safe, tactile sculptures create visual and sensory focus.
  • Seasonal moments: Activities like scavenger hunts or tending a herb patch add gentle structure and fun. 

One example from our communities: 

“The birds and other natural visitors to the garden are always a talking point for our residents. It often helps them recall fond memories of past pets or times spent in their garden.” 

Familiarity and Memory Support

Familiar Plants

Traditional plants such as roses, honeysuckle or herbs offer comfort through recognition and can initiate personal memories or stories. 

Memory Corners

Dedicated areas with nostalgic plants, objects or photos help support identity, encourage reminiscence and create natural opportunities for conversation. 

Therapeutic Gardening

Simple tasks (watering, planting seeds, trimming herbs) offer purpose and a sense of achievement. For many, these activities feel grounding and deeply familiar. 

Staff Involvement and Training

A sensory garden thrives when it is actively used and understood.

  • Training: Teams and families learn how to use the space thoughtfully, not just as a garden, but as a therapeutic environment.
  • Seasonal care: Regular maintenance keeps the garden engaging, colourful and safe all year round. 

Case Study: The Sensory Garden at Cedar View Care Centre

Designed by Erik Cortez, Clinical Deputy Manager, the sensory garden at Cedar View is a vibrant example of what careful planning and collaboration can achieve.

 

“Selecting specific plants and features for the sensory garden at Cedar View required meticulous planning and collaboration. Seasonal plants were thoughtfully chosen to ensure perpetual blooming and greenery.

 

Central to our garden, the water fountain sphere, although a pre-existing feature, underwent necessary repairs to become a functional and aesthetic focal point. We prioritised the inclusion of non-poisonous, scented, and colourful plants for a safe and engaging sensory space for all our residents to explore and enjoy.

 

Cedar View Care Centre, partnered closely with a local gardener, ensuring the space remains healthy, stimulating and loved throughout the year and beyond. The partnership also ensured excellent value and specialist guidance.

Plants Recommendations for Sensory Gardens

Mark Reeve, Senior Plants Advisor at Coolings Garden Centre recommends:

Santolina, Brachyglottis, Convolvulus cneorum, Lavandula, Edelweiss, Stipa tenuissima and Thymes such as Woolly Thyme, are all good to brush your hands through. Most herbs are good for scent so again, Thyme is a great choice – there are lots of different types of scented thyme too. Rosemary, Sage, Mint, Lemon Balm, Lemon Verbena, Basil are other wonderful herbs to incorporate. 

Be mindful when choosing shrubs as some of the scented ones are toxic – Daphne being one. Buddleja or Osmanthus delavayi would provide scent through the spring and summer. 
 

Mark also notes that herbs thrive in well-drained soil and sunny spots, making them an ideal foundation for many sensory gardens.

Why Sensory Gardens Matter

A well-designed sensory garden can: 

  • Stimulate all five senses in gentle, supportive ways 
  • Evoke memories and positive emotions 
  • Reduce feelings of anxiety 
  • Encourage movement and build confidence outdoors 
  • Create calm, connection and comfort 
  • Support identity and independence 
  • Nurture social interaction with loved ones and staff
     

For people living with dementia, these spaces are not simply gardens, they are places of belonging, reassurance and joy.
