Introducing joy, elegance, or whimsy into a garden design could be as simple as a trip to the local nursery. The underlying trick to transforming an outdoor space is to first decide what kind of emotional vibe you would like your landscape to radiate, and then deliberately seek out the botanical specimens that naturally evoke those specific feelings. In an entertaining and insightful episode of Super Cool Plants — The Podcast, expert designers Catharine Cooke and Susan Morrison share a curated selection of plant choices designed to spark imagination and encourage gardeners to think deeply about the moods they want to bring into their own outdoor living spaces.
Listeners can tune in to the episode directly or catch the discussion on their favorite podcast platforms, as well as watch the visual version on the official Super Cool Plants YouTube channel. The conversation offers a deep dive into landscape aesthetics, moving beyond traditional layout and color theory to explore how plants act as emotional anchors in garden design.
Plants That Set a Mood
Designers have long understood that landscapes do more than just look pretty; they actively influence how people feel when stepping outside. By categorizing plants according to the psychological responses they elicit, Cooke and Morrison demonstrate how targeted plant selections can completely shift the atmosphere of a backyard, courtyard, or patio.
Mood: Joyful
To infuse a garden with a sense of unadulterated happiness and bright energy, designers look to specimens with vibrant color profiles and lively growth habits. Among the standout recommendations for a joyful atmosphere is the ’Victor Reiter’ flowering maple, scientifically known as Abutillon. With its cheerful, dangling bell-shaped blossoms swaying gently in the sunlight, this plant brings instant animation to a garden bed.
Complementing the flowering maple are traditional yet exceptionally effective choices like the Sparky Mix French marigold, courtesy of American Meadows. Marigolds are classic staples that offer fiery, saturated tones of gold, orange, and mahogany, injecting immediate warmth into borders and containers. Another powerful addition to the joyful category is butterfly weed (Asclepias tuberosa). Boasting brilliant clusters of bright orange blossoms, this native perennial not only delights the human eye with its radiant coloration but also brings life and movement to the garden by actively attracting pollinators, ensuring the space feels dynamic and alive.
Mood: Elegant
When the design goal shifts toward sophistication, sleek lines, and refined beauty, the plant palette must adapt accordingly. The ’Mission to Mars’ mangave serves as a striking example of modern elegance. This hybrid combines the architectural structure of agaves with the softer spotting of manfredas, resulting in a dramatic, sculptural focal point that commands attention without feeling cluttered.
For a softer, ethereal form of elegance, the Phalaenopsis orchid is introduced as a masterclass in understated grace. Though often grown indoors or in protected patio environments, its cascading sprays of symmetrical, moth-like blooms introduce an instant sense of luxury and polished design refinement to any setting where it is featured.
Mood: Nostalgic
Gardens often serve as sentimental spaces that transport visitors back to cherished memories of childhood or historic country estates. To capture this sentimentality, designers turn to plants steeped in tradition and sensory familiarity. The ’Petite Butterfly’ sweet pea shrub (Polygala fruticosa) offers a romantic, cottage-garden feel with its delicate, pea-like flowers that evoke simpler times and classic landscape aesthetics.
Equally powerful in evoking nostalgia is the common lilac, specifically varieties like Syringa vulgaris ’Wedgewood Blue’. The heavy, unmistakable fragrance of blooming lilacs has a unique capacity to evoke memories of late spring days from decades past. By incorporating these time-honored woody plants into modern layouts, designers can bridge contemporary outdoor living with timeless horticultural heritage.
Mood: Whimsical
Whimsy introduces an element of surprise, playfulness, and the unexpected into landscape design, preventing a yard from feeling too formal or rigid. The Cousin Itt acacia stands out as a prime example of a plant that embraces a whimsical aesthetic. Named after the famously eccentric, hair-covered television character, this weeping, mounding shrub features dense, fine-textured foliage that flows downward in an unorthodox, quirky fashion. It invites curiosity and a lighthearted smile from anyone who encounters it in the landscape.
Mood: Hopeful
Springtime often symbolizes renewal and optimism, and certain plants capture that sentiment throughout their blooming cycles. The Butterflies magnolia in bloom serves as an inspiring focal point that embodies the feeling of hope. As its soft, yellow, tulip-shaped flowers open against the bare branches of early spring, the plant signals the end of winter dormancy and the promise of warmer, brighter days ahead, filling the gardener with a sense of renewal and forward-looking optimism.
Mood: Disney Princess
For those who wish to lean into a fairy-tale aesthetic characterized by romantic grandeur and storybook charm, botanical choices must offer a sense of theatrical beauty. The ’Superb’ silky oak provides this enchanting quality with its deeply cut, fern-like foliage and striking floral displays. Its dramatic presence feels right at home in a magical, storybook-inspired garden where imagination takes center stage.
Mood: Contemplative
In contrast to the high-energy and whimsical spaces, a contemplative garden requires elements that encourage quiet reflection, relaxation, and mindfulness. The laceleaf Japanese maple (Acer palmatum dissectum) is the quintessential plant for this mood. With its delicate, weeping habit and finely dissected foliage that shifts gracefully through the seasons, the laceleaf Japanese maple creates a tranquil, meditative canopy. Its graceful, cascading structure invites visitors to slow down, pause, and find a moment of peace amidst the complexities of daily life.
