Why the Best Landscapes in Orange County Borrow from the Surrounding Hills, Not from a Catalog

September 21, 2026 · Gavin Mohrmann, Orange Path Landscaping


Drive up into the Santa Ana Mountains on a clear January morning and just look. The hillsides are doing something remarkable that no landscape catalog has ever managed to replicate: they're alive in a way that feels inevitable. Buckwheat fading from copper to rust. Coastal sage scrub catching the low winter light like brushed silver. A lone sycamore with bark so pale it almost glows against the chaparral. Nobody planted any of that. Nobody irrigated it. Nobody chose a color palette.


And yet it's stunning.


That's the thing I keep coming back to, year after year on this job. The land around us — the hills above Irvine, the arroyos threading through Laguna, the bluffs above the coast — has spent thousands of years figuring out exactly what belongs here. The colors, the textures, the way plants layer themselves from the ground up. It's already solved the design problem.


The question I ask on every project is: are we listening to that, or are we fighting it?


The Catalog Problem


I'm not trying to be harsh, but I'll say it plainly: a lot of landscapes in Orange County look like they were ordered out of a box. Same Italian cypress. Same clipped boxwood hedges. Same stamped concrete in that one shade of gray-brown that somehow ends up on every new build from Tustin to San Clemente. Same three ornamental grasses from the Home Depot rack, planted in a row like they're standing at attention.


None of it is wrong, exactly. It's just... nowhere. It doesn't tell you anything about where you are. You could drop that landscape into suburban Dallas or suburban Phoenix and it would look exactly the same. That's a missed opportunity, and honestly, it's also a lot of work for something that doesn't pay you back in beauty.


The catalog approach treats plants and materials as interchangeable units. Something to fill space. Something to check a box. It prioritizes tidiness over character, uniformity over soul. And in a place as naturally extraordinary as Southern California, that feels like a real shame.


What the Hills Are Actually Teaching Us


When I spend time in the hills — and I do, regularly, because I think it's part of my job — I notice a few things that I try to carry back into every design I work on.


**Nothing is perfectly symmetrical.** Plants in nature don't mirror each other. They cluster and drift. They leave open pockets of space that feel intentional without being calculated. When I'm placing plants on a property, I'm trying to recreate that rhythm — not scatter things randomly, but arrange them the way the land would if it had good taste and a loose hand.


**Texture does more work than color.** The hills aren't colorful most of the year. They're gray-green, silver-green, dusty olive, pale gold. What makes them beautiful is texture — the feathery softness of Cleveland sage against the hard, skeletal architecture of a dead manzanita branch. The way fine-bladed grasses catch wind movement while a boulder beside them stays completely still. That contrast of soft and hard, moving and fixed, is something I think about constantly.


**Rock isn't decoration. It's structure.** Out in the chaparral, boulders aren't placed for effect. They're just there, and everything else organizes itself around them. They create shade. They hold soil. They break the wind. They're part of the ecosystem. When I bring boulders into a design, I want them to feel that same way — like they belong to the ground they're sitting in, not like they were set-dressed last Thursday.


**The ground between plants matters.** I see a lot of landscapes where every inch of bare soil is covered — usually with shredded bark, sometimes with gravel. But in a natural landscape, that bare ground is doing something. It's breathing. It's part of the visual composition. I'm not saying leave bare soil exposed where you'll have erosion, but I am saying: resist the urge to carpet everything. Give the plants room to be themselves.


Materials That Say "Southern California"


This translates directly into how I think about hardscape, too.


Concrete is fine. I use it. But smooth, poured concrete doesn't have a voice here the way flagstone does. Find the right decomposed granite pathway threading through native plantings, or a dry-stacked stone wall using materials that echo the color of the local hillside — that's when hardscape starts to feel like it grew out of the ground instead of being applied to it.


I love:


  • **Buff and golden flagstone** — it pulls in the color of dry summer grasses and sun-bleached rock
  • **Boulders as focal points** rather than block walls as boundaries
  • **Decomposed granite in warm tan or sandy tones** instead of that blueish crushed gravel that reads as cold and industrial
  • **Dry creek beds with rounded river rock** — functional drainage and one of the most naturally beautiful features you can add to a Southern California property
  • **Wooden elements that weather** — rough-hewn, not over-finished

  • These aren't exotic or expensive choices, necessarily. They're just choices made with the landscape in mind rather than a product catalog.


    The Plants That Belong Here


    I'll talk about California natives more in future posts because there's so much to say. But briefly: the chaparral plant palette is one of the most beautiful, low-maintenance, and visually interesting you can work with anywhere in the world.


    Some of what I reach for constantly:


  • **Cleveland sage** (*Salvia clevelandii*) — that fragrance alone is worth designing a garden around
  • **Deer grass** (*Muhlenbergia rigens*) — graceful, tough, honest
  • **Toyon** (*Heteromeles arbutifolia*) — the plant that supposedly gave Hollywood its name, and it earns it in winter with those red berries
  • **Lemonade berry** (*Rhus integrifolia*) — dark green, salt-tolerant, makes a living wall that actually looks alive
  • **Ceanothus** in any of its forms — that blue flower in spring is something you don't forget
  • **Blue-eyed grass** (*Sisyrinchium bellum*) as a ground layer — tiny purple flowers, very little water, genuinely lovely

  • These plants aren't trying to be something they're not. They're here because they evolved here. They make sense here. And when they're planted with an eye toward how they'd grow naturally — in loose drifts, with room to breathe, in the right exposure — they'll do things that impress you every season of the year without you doing much at all.


    The Honest Truth About This Approach


    I'll be real with you: this kind of design takes more thought up front than pointing at a catalog. It requires knowing plants deeply — how they grow, how large they get, what they need in each season, how they interact with each other. It requires understanding soils and drainage and sun exposure in a specific way for a specific site.


    It also requires a client who trusts the process. Who can look at a newly planted landscape and see what it's going to become, not just what it is on installation day. The most rewarding projects I've worked on are the ones where someone said: *make it feel like it was always there.* That's the brief I love. That's when I can really work.


    Because that's ultimately what borrowing from the surrounding hills means. Not copying nature literally — you can't, and you shouldn't try. But paying close enough attention to it that your design earns its place in this landscape. That it looks less like something you bought and more like something you found.


    That's the goal. That's always the goal.
