The 40-Foot Mountain of Mums You Can Actually Climb
Imagine standing at the base of a hill so covered in flowers that you can barely see the soil beneath them. That’s exactly what greets visitors at Ott’s Exotic Plants every fall, when the famous Mountain of Mums rises nearly 40 feet into the Pennsylvania sky.
It’s not just something to look at from a distance — you can walk right up it.
Stone steps and winding paths guide visitors from the base all the way to the top, making the climb accessible for most ages and fitness levels. Kids especially love the sense of adventure that comes with ascending a real hillside blanketed in blooms.
The ascent offers changing views at every turn, with splashes of yellow, orange, purple, and red surrounding you on all sides.
At the summit, the payoff is worth every step. You get a sweeping panoramic view of the entire garden center below, framed by the colorful mums stretching across the hillside.
It’s the kind of moment that makes you stop and just take it all in. For many visitors, reaching the top of the flower mountain is the highlight of their entire trip to Montgomery County.
A Fall Tradition Featuring Thousands of Blooming Flowers
Every autumn, something magical happens at Ott’s Exotic Plants. Between 6,000 and 10,000 chrysanthemum plants are carefully arranged across the hillside, transforming it into one of the most visually stunning seasonal displays in all of Pennsylvania.
The sheer number of blooms is almost hard to believe until you’re standing right in front of them.
Mums come in a dazzling range of colors — deep burgundy, bright gold, soft lavender, snowy white, and vibrant orange — and the hill seems to shift in appearance depending on where you’re standing and how the light hits it. Peak bloom usually arrives in mid-to-late October, making it a perfect destination for a fall weekend outing.
Timing your visit for that window almost guarantees the most spectacular display.
The tradition has been going on for decades, and it’s become a seasonal ritual for many Pennsylvania families. Some visitors make the trip every single year, watching their kids grow up against the same floral backdrop.
There’s something genuinely heartwarming about a place that marks the turning of the season in such a colorful and generous way. It’s autumn celebration at its most beautiful.
Winding Paths, Stairs, and a Hidden Tunnel
Getting to the top of the flower mountain isn’t just about the destination — the journey itself is half the fun. Ott’s has thoughtfully designed the hill with stone steps and curving pathways that make the climb feel like an adventure rather than a workout.
Around every bend, a new cluster of flowers greets you with fresh colors and textures.
But the real showstopper for many visitors? The tunnel.
Carved right through the base of the hill, this hidden passageway lets you walk beneath the entire floral mountain and emerge on the other side. It’s unexpected, a little mysterious, and completely delightful — especially for kids who feel like they’ve discovered a secret passage through a garden fortress.
The tunnel adds a playful, storybook quality to the whole experience. Adults who walk through it often find themselves grinning like kids, because it’s just that charming.
The combination of climbing paths, stone steps, and the hidden tunnel makes the flower mountain feel like a fully interactive attraction rather than a passive display. You’re not just looking at the art — you’re moving through it, which makes the whole visit feel much more personal and alive.
A Storybook Photo Spot at the Top
Reaching the top of the Mountain of Mums comes with a reward that no filter can improve. From the summit, you get a sweeping view of the entire garden center spread out below — greenhouse rooftops, colorful flower beds, and the patchwork of mums cascading down the hillside in every direction.
It’s genuinely breathtaking on a clear October afternoon.
The overlook has quietly become one of the most popular photo spots in Montgomery County during fall. Families, couples, and solo visitors all make the climb specifically to capture that perfect seasonal shot.
The natural framing of flowers in the foreground and the Pennsylvania countryside in the background creates images that look almost too good to be real.
What makes this spot special beyond the visuals is the feeling it gives you. Standing at the top, surrounded by color and fresh autumn air, there’s a quiet sense of accomplishment and joy that’s hard to manufacture.
It’s the kind of moment that ends up as a screensaver or a framed photo on a living room wall. For families building seasonal traditions, this summit view has a way of becoming something genuinely treasured year after year.
A Greenhouse That Feels Like a Tropical Escape
Step through the greenhouse doors at Ott’s and the Pennsylvania autumn disappears entirely. Inside, the air turns warm and humid, carrying the earthy scent of soil and tropical greenery.
Towering palms stretch toward the glass ceiling, hanging vines drape over wooden beams, and exotic plants crowd every pathway in the most wonderfully overwhelming way.
The greenhouse feels less like a retail space and more like a botanical garden that happens to have price tags. Rare tropical specimens sit alongside popular houseplants, giving both seasoned collectors and curious beginners plenty to explore.
You could spend a full hour wandering through the different sections and still feel like you haven’t seen everything.
For visitors who come during the colder months, the greenhouse is especially magical. When the world outside is gray and bare, walking into that warm, green, flower-filled space feels like a genuine escape.
It’s the kind of environment that lifts your mood almost instantly. Whether you’re shopping for a new plant or just soaking in the atmosphere, the greenhouse at Ott’s delivers a lush, sensory-rich experience that’s completely unlike anything you’d find at a typical garden store in the region.
Waterfalls, Koi Ponds, and Lush Indoor Gardens
Hidden inside the greenhouse at Ott’s is one of the most unexpected features of the entire property — a two-story indoor waterfall that tumbles down into a koi pond below. The sound of moving water fills the surrounding space, giving the area a peaceful, almost meditative quality that makes you want to pull up a bench and stay a while.
Wooden bridges arch over the water, and dense tropical plants press in from every side, creating the sensation of standing inside a private jungle oasis. Colorful koi glide through the pond below the falls, adding movement and life to the already vibrant scene.
It’s the kind of detail that makes first-time visitors stop mid-step and say, “Wait — is this really a garden center?”
The indoor garden surrounding the waterfall is carefully curated to feel wild and natural while still being completely accessible. Walkways wind through the greenery, giving visitors a chance to explore at their own pace.
For kids, spotting the koi and listening to the waterfall is endlessly entertaining. For adults, the whole space offers a rare moment of genuine calm.
It’s a reminder that a garden center can be so much more than just a place to buy plants.
A Century-Old Family Business With a Remarkable Origin
Not many businesses can trace their roots back to 1914, but Ott’s Exotic Plants is one of them. The story begins with Godfrey Ott, a German immigrant who arrived in Pennsylvania with a passion for plants and an extraordinary will to succeed.
What makes his story even more remarkable is that Godfrey had been paralyzed from the waist down since childhood — yet he built a thriving nursery business from the ground up.
Starting by selling plants directly from his home, Godfrey turned personal determination into a community institution. His hard work laid the foundation for what would eventually grow into one of the most beloved garden destinations in the Philadelphia region.
The business stayed in the family through multiple generations, each one adding its own chapter to the story.
That history gives Ott’s a soul that newer businesses simply can’t replicate. When you walk through the property, you’re walking through more than a century of family dedication, horticultural passion, and community connection.
Knowing the origin story makes every visit feel a little more meaningful. It’s a powerful reminder that the best businesses are often built not just on ambition, but on genuine love for what you do and resilience in the face of real challenges.
Seasonal Displays Beyond the Flower Mountain
The Mountain of Mums gets most of the attention, but Ott’s Exotic Plants has something worth seeing in every season. Throughout the year, the property transforms to reflect what’s blooming, growing, or harvested — making repeat visits genuinely rewarding rather than repetitive.
Each season brings its own personality to the grounds.
Come fall, pumpkins and gourds join the mums in creating a full harvest atmosphere. In spring and summer, the focus shifts to colorful annuals, perennials, and an ever-rotating selection of tropical plants that fill the greenhouse with new arrivals.
Succulent lovers will find dedicated sections stocked with an impressive variety of low-maintenance favorites year-round.
The nursery side of the business is fully functional and well-stocked, offering gardening supplies, soil, containers, and expert advice alongside the plants themselves. So even when you’re not visiting for the spectacle of the flower mountain, there are practical reasons to stop by.
Many locals treat Ott’s as their go-to garden resource throughout the growing season, building a relationship with the staff over years of visits. The combination of destination appeal and genuine horticultural expertise makes this garden center valuable no matter what month you walk through the door.
Essential Visitor Information for Planning Your Trip
Planning a visit to Ott’s Exotic Plants is pretty straightforward, and the best news is that admission to the property — including climbing the flower mountain — is completely free. You only pay if you decide to take plants or products home, which, fair warning, is very easy to do once you’re surrounded by all that beauty.
The garden center is located at 861 Gravel Pike in Schwenksville, Pennsylvania, right in the heart of Montgomery County. Free parking is available on-site near the greenhouse and behind the mountain, so you won’t need to worry about squeezing into a tight lot.
Hours typically run from around 9 a.m. daily, though closing times shift with the seasons, so it’s worth checking ahead before you go.
For the most spectacular mum display, aim to visit between mid-September and late October when the chrysanthemums hit peak bloom. The garden center sits within easy driving distance of Valley Forge and other Montgomery County attractions, making it a natural anchor for a full day trip from Philadelphia or the surrounding suburbs.
Whether you’re making a quick stop or turning it into a leisurely afternoon, Ott’s is the kind of place that tends to hold you longer than you planned.
