There is a place in Boise, Idaho, where the air smells like rich earth and fresh blossoms the moment you walk through the door, and where the warmth never leaves, even in the dead of winter. It holds a secret that most plant lovers do not know about until their first visit: the heat keeping all those lush plants alive has been flowing naturally from the ground since 1927.
That detail alone is enough to make any curious mind want to know more. This family-owned destination has been growing its roots in the Treasure Valley for nearly a century, and it has quietly become one of the most beloved spots in all of southern Idaho.
Whether you are hunting for a rare Japanese Maple, a hand-tied bouquet, or simply a peaceful afternoon surrounded by green, this place delivers something genuinely special every single time. Read on to discover exactly what makes it so worth the visit.
A Legacy Rooted in Geothermal Warmth

Long before most people had ever heard the word “geothermal,” a resourceful Idaho farmer drilled a well in 1927 and discovered something remarkable beneath the Boise soil: natural hot water sitting right at the ready. That single well became the foundation for what is now Edwards Greenhouse and Flowershop, located at 4106 W Sand Creek Street in Boise, Idaho 83703.
Thomas F. Edwards and his son launched a truck farm in 1930, using that geothermal water to heat their growing operation and extend the short Idaho growing season.
They delivered fresh vegetables to local grocery stores and even door-to-door, earning a respected reputation in the community.
When Paul Edwards took over in 1947, the focus shifted toward cut flowers and annuals, and the business began its transformation into the full retail greenhouse it is today. That original geothermal well still flows, making this the oldest commercially geothermal-heated greenhouse in America, a distinction that is hard to top.
What the Address Does Not Prepare You For

The first thing that surprises most visitors at Edwards Greenhouse is how much there is to see once they get past the front entrance. The parking lot is dirt, and the entry can feel a little unclear on a first visit, but none of that matters once you are inside and the full scope of the place opens up around you.
A serene koi pond greets you near the entrance, its colorful fish gliding calmly beneath the surface, immediately setting a relaxed and unhurried tone. Look down as you walk and you will notice concrete pathways embedded with colored glass that catch the light and guide you deeper into the space.
Spread across 90,000 square feet of covered greenhouse area, the layout meanders and winds in a way that makes every turn feel like a discovery. Local artwork is displayed throughout the property, adding unexpected visual interest that complements the natural beauty of the plants surrounding it.
Plan to stay longer than you think you need.
Annuals in Every Color You Can Imagine

Over 2,000 varieties of annuals fill the shelves at Edwards Greenhouse throughout the year, rotating with the seasons in a way that keeps the displays looking fresh and exciting no matter when you visit. Spring brings potted bulbs like crocus, hyacinth, muscari, narcissus, and tulips that practically glow under the greenhouse lights.
Summer is when the tropical section really steals the show, with alocasia, cannas, colocasia, caladiums, annual hibiscus, and mandevilla creating a lush, almost jungle-like atmosphere inside the growing areas. Fall rolls in with rich mums, asters, pansies, violas, ornamental kale, and decorative peppers that add warm seasonal color to any outdoor space.
Even winter has its moment here, with poinsettias, amaryllis, azaleas, cyclamen, and paperwhites ensuring the greenhouse never loses its color or charm. Paul Edwards is credited with introducing the first hybridized annuals to the Treasure Valley, and that pioneering spirit is still very much alive in the selection today.
Perennials, Roses, and the Queen of Vines

The perennial section at Edwards Greenhouse is where serious gardeners tend to lose track of time entirely, and honestly, it is easy to understand why. With over 1,000 cultivars on offer, the selection includes more than 40 varieties of Heuchera, over 60 types of Daylily, and upward of 50 Hosta options, along with a seemingly endless collection of Echinacea.
Clematis, affectionately called the Queen of Vines, gets its own impressive showcase with over 2,000 individual plants spanning colors from soft wedgewood blue to vibrant red and crisp white. The vine section also includes everything from Akebia to Wisteria, giving gardeners plenty of options for adding vertical interest to any landscape.
Every February, more than 4,000 bare root roses arrive at the greenhouse, where they are meticulously pruned, potted, and fertilized before hitting the sales floor. Pre-ordering your favorites is an option worth taking advantage of, especially for popular varieties that tend to sell out quickly each spring season.
Trees, Shrubs, and the Japanese Maple Collection

Few things in a plant nursery stop you in your tracks quite like a well-grown Japanese Maple, and Edwards Greenhouse has more than 100 of them. The collection ranges in size, color, and leaf shape, making it one of the most impressive displays of this particular tree available anywhere in the Treasure Valley.
Beyond the maples, the tree selection includes magnolias, crabapples, redbuds, stewartia, flowering dogwoods, and even locally grown fruit trees, giving both ornamental and practical gardeners plenty to get excited about. The shrub section is equally strong, with more than 30 hydrangea cultivars alone drawing admiring looks from visitors who did not even come in planning to buy a shrub.
Citrus trees are another surprising find here, and the knowledgeable staff will happily explain how dwarf rootstock citrus can actually overwinter successfully in a Treasure Valley garage. That kind of specific, practical advice is exactly what sets this place apart from a typical big-box garden center.
Generations of Family Dedication Behind Every Plant

What makes a business last nearly a century? At Edwards Greenhouse, the answer is a deeply rooted family commitment that has passed from one generation to the next without losing its original passion.
Thomas F. Edwards started it all in 1930, his son Paul transformed the business in 1947 by bringing hybridized annuals to the region, and the baton passed again in 1986 when Paul retired and his daughter Garnette stepped in.
The fourth generation arrived around 2010, when Erin Monnie joined the operation, bringing fresh energy while honoring the traditions that had made the greenhouse a community institution. Each transition has been marked not by disruption but by thoughtful growth, including the addition of Gem Butte Greenhouse in Emmett, Idaho, in 2003, which now serves as a secondary growing site benefiting from cooler temperatures and excellent water quality.
That sense of continuity is palpable throughout the property. The care taken with every plant, the warmth extended to every visitor, and the pride visible in every corner of the operation all trace back to a family that genuinely loves what it does.
The Full-Service Flowershop That Goes Beyond Bouquets

Added to the greenhouse family in 1991 and fully remodeled in 2008, the Florist at Edwards is a destination in its own right. The shop handles everything from casual everyday bouquets to elaborate event florals, and the creative talent behind the arrangements consistently earns high praise from customers across the Treasure Valley.
Wedding florals are a particular specialty here, with the team designing bouquets, ceremony arches, and reception centerpieces that reflect each couple’s unique vision. The florists listen carefully, ask thoughtful questions, and deliver results that routinely leave clients speechless on their big day.
Sympathy arrangements are handled with equal care and sensitivity, each piece crafted to honor the person being remembered.
For those who want fresh flowers on a regular basis, the shop offers convenient subscription options delivered weekly, bi-weekly, or monthly, perfect for brightening a home or welcoming guests into a business. The John and Karola Carpenter Cutting Garden is also in bloom during the season, offering a U-Pick experience that turns flower gathering into a genuinely joyful outing.
The Legacy Gardens and the Charm Hidden in Plain Sight

Beyond the greenhouse structures themselves, the Legacy Gardens offer a beautifully maintained outdoor space that adds a whole new dimension to the visit. A charming gazebo anchors the area, surrounded by gorgeous flowering borders that showcase what a well-planted garden can look like at its very best.
A children’s play area sits nearby, making the Legacy Gardens a genuinely family-friendly destination where parents can linger over the perennial displays while kids burn off some energy in a safe and pleasant environment. It is the kind of thoughtful detail that turns a plant shopping trip into a full afternoon outing worth planning around.
The grounds also feature a “lawn chair” covered entirely in living grass, a playful sculptural touch that perfectly captures the whimsical spirit running through the entire property. These small, intentional surprises are part of what makes Edwards Greenhouse feel so different from a standard nursery.
Every corner rewards a curious eye, and the Legacy Gardens are no exception to that delightful rule.
Staff Who Actually Know Their Plants

Ask anyone who has visited Edwards Greenhouse what stands out most, and there is a very good chance the answer involves the staff. Helpful, knowledgeable, and genuinely enthusiastic about plants, the team here treats every question as a worthwhile one, whether you are a first-time plant parent or a seasoned collector chasing a specific cultivar.
Need full-sun plants for large outdoor pots and have no idea where to start? The staff will walk you through the options, explain care requirements, share planting tips, and help you leave with exactly what your space needs.
That level of personalized attention is increasingly rare in retail, and it makes a real difference in whether the plants you take home actually thrive.
The greenhouse also stocks seeds from local grower Snake River Seeds, another example of the thoughtful, community-minded curation that defines the overall shopping experience here. When the people behind the counter care this much about what they are selling, it shows in every interaction and in every healthy plant that goes home with a happy customer.
Practical Tips for Getting the Most Out of Your Visit

A few practical details can make the difference between a good visit and a great one at Edwards Greenhouse. The greenhouse is open Tuesday through Saturday from 9 AM to 5 PM and on Sundays from 10 AM to 4 PM.
Monday is a closed day, so plan accordingly and avoid an unnecessary trip across town.
The parking lot is dirt and has a couple of potholes worth navigating carefully, particularly for anyone with mobility considerations. First-time visitors sometimes find the entrance slightly confusing, so give yourself a moment to orient before heading in.
Once you are through the door, the koi pond and the glass-embedded walkways will guide you naturally into the heart of the space.
Weekend visits often coincide with pop-up markets that bring additional garden gifts and accessories from local vendors, making those days especially worthwhile if you enjoy browsing unique finds. Military personnel, seniors over 65, and representatives from schools or community gardens all qualify for a 10% discount, so bring your ID and mention it at the register before checking out.
A Community Cornerstone That Keeps on Growing

Edwards Greenhouse has never been content to simply sell plants and send people on their way. Over the decades, it has actively embedded itself into the social and educational fabric of the Boise community in ways that go well beyond the nursery business.
Grade school children visit on field trips, high school horticulture students learn from the staff, and local garden clubs gather here regularly to share knowledge and enthusiasm.
The greenhouse supports non-profit community gardens through discounts and donations, understanding that access to fresh produce and gardening education strengthens neighborhoods in lasting and meaningful ways. Their advocacy for the arts and for women’s and children’s causes further reflects a values-driven approach to doing business that resonates deeply with the local community.
With a 4.8-star rating across hundreds of reviews and a presence in Boise stretching back to 1930, Edwards Greenhouse has earned its reputation the old-fashioned way: through consistency, quality, and genuine care for the people it serves. That kind of trust takes generations to build, and it shows in every visit, every purchase, and every blooming plant that leaves the property.
