Stone-Based Gardens. Horticultural Design. Living Landscapes.

Vertically stratified stones with narrow soil-filled crevices and sporadic planting pockets mimic natural mountain geology and composition. HORTCO's Nook n' Crevice™ installations are perfect for any space, large or small, and there is no better way to enhance an existing landscape. Crevice gardens allow exceptional drainage while creating cool root zones and microclimates ideal for a diverse range of drought-tolerant and specialty plants. We get the spaces in between.

Naturalistic compositions using boulders, up to several thousand pounds each, shepherd dynamic plantings—the way nature's been doing it all along. Megalithic ambience, a bold permanence—just imagine what your outdoor landscape will look like with HORTCO's Boulder Approach™.

See how HORTCO's plant-forward, stone-based design reimagines water features! We design our water features to look, feel, and sound as though they always been there. These installations create sound, movement, and cooling effects within the landscape, while unlocking high-density site-specific botanical diversity. Our systems prioritize long-term ease of maintenance. We follow nature's example, and we build 'em right.

HORTCO's Urbanite Outfitters™ installations check all the same boxes as natural stone crevice gardens while offering a uniquely modern and sustainable aesthetic. Far from being a compromise, we rearrange secondhand concrete into striking geological formations, brought to life by richly diverse plantings. HORTCO's upcycled "urbanite" crevice gardens authentically and impactfully embody the true spirit of sustainability—and may actually be the best concrete has ever looked. Some things, it turns out, are better the second time around.

HORTCO's The Emperor's Koi™ ponds carry our plant-forward philosophy below the waterline. We compose the pond itself through stone—creating the kind of rich, irregular geology where water disappears between boulders, plants emerge from unexpected places, and every edge invites a closer look. We build our ponds to look natural—or we don't build them at all. Koi, like plants, simply look better with stone.

HORTCO orchestrates something greater than escape. Our Emperor's Koi™ ponds offer solace—the sublime asymmetry of an entire day immersed in a moment beside placid water. Let that soak in for a minute.

HORTCO's Boulder Bogs™ take bog and rain gardens somewhere they've never been. By combining carefully engineered wet habitats with the geologic drama of boulder and crevice gardens, we create astonishing gradients from hot, dry rock faces to perpetually moist planting pockets—allowing xeric and bog plants to thrive side by side—without asking either to meet in the middle. The result is bog gardening reimagined: seemingly impossible plant combinations made to look as though nature put them there herself. Whether capturing stormwater or showcasing carnivorous plants, Boulder Bogs™ can fit almost anywhere and integrate seamlessly with any other HORTCO installation.
