Adapted Non-Natives Worth Your Space, Like Lavender
Okay. Before anybody emails me, yes, I know this is the "Natives That Handle Our Valley" module and lavender is not native to Utah. It's not native to anywhere near here. It's from the Mediterranean. I'm putting it in anyway, because this whole class is called Drought Tolerant Plant Selection, not Natives Only, and I think we'd be doing you a disservice if we acted like a plant has to have grown here for ten thousand years to earn a spot in your yard.
Here's the thing about lavender and its friends — Mediterranean stuff, generally — they evolved in a place with alkaline soil, hot dry summers, and lousy water. Sound familiar? That's basically our whole pitch for natives, except lavender didn't grow up here, it grew up somewhere with the SAME PROBLEMS. Different continent, same headaches. So it adapts to our valley just fine, it's just not technically "from" it. I call that adapted non-native, and honestly I think it's an underused category. People go all-in on natives or all-in on a Home Depot flat of petunias, and there's a whole middle ground of plants that came from someplace hard and dry and will do great here too.
What Else Is in This Category
Lavender's the poster child, but it's not alone. Things I'd put in the same bucket for our valley:
- Lavender (English or Spanish types, not French — French lavender is not reliably hardy for us, I've watched people lose it over a normal winter)
- Russian sage — technically not a sage, it's in the mint family, don't ask me why they named it that
- Catmint (nepeta) — not the stuff that gets your cat drunk, different plant, similar name, confusing
- Santolina, sometimes called lavender cotton, if you want something low and silvery
- Sedum varieties, especially the upright kinds
All of these want the same basic deal: full sun, soil on the leaner side, and once they're established, you leave them alone. Which, if you've been in this class a few weeks, you already know is my whole thing.
Getting Lavender Established Without Killing It
Buy small. One-gallon, maybe a quart if you can find it. I know the five-gallon lavender at the nursery looks impressive and instant, but it costs three times as much and it doesn't actually establish faster. I'd rather you buy three one-gallons for the price of one big one and end up with more plants that all take root just fine.
Plant it somewhere with real drainage. If you've got heavy clay, dig your hole a little wide, not deep, and don't dump a bunch of good compost in there — we covered this a few weeks back, lavender does not want rich dirt any more than a penstemon does. It wants the lousy native stuff, maybe with a handful of gravel or decomposed granite worked in if your soil holds water like a bathtub.
Water it like a new plant for the first season — regularly, enough to get the roots going — and then back off HARD the second year. This is where I lose people. Lavender that gets watered like a tomato plant every summer of its life gets leggy, woody, and rots out in the middle. You want to basically ignore it once it's established. If you're watering it more than once a week by year two, you're loving it to death.
Cut it back in early spring, before new growth really gets going, down to about a third of its size. If you never prune it, it turns into a sad woody stick with a few tufts of green on top after a few years. I didn't know this for a long time and wondered why my neighbor's lavender looked like a plant and mine looked like a shrub having a bad day.
The Raised Bed Story
I've mentioned Von built me a raised bed out of scrap cedar, and the corners are slightly out of square because he built it without me asking and didn't use a level the way I would have. I love that bed more than any straight, store-bought one I could've bought myself. It's where I try new stuff before I commit it to the front yard where the whole neighborhood can watch me fail.
Lavender was one of the first things I trialed in there. I wanted to see if it'd actually tolerate my soil and my watering habits before I put four of them along the front walk where they'd be highly visible if they died. It did great in that crooked bed. Better than some of my natives, honestly, the first year. That's when I started thinking about this whole "adapted non-native" category as its own thing worth teaching, instead of just an afterthought.
A Caution Worth Saying Plainly
Lavender and Russian sage both attract bees, a lot of bees, when they're blooming. That's a feature, not a bug, if you like pollinators, which you should. But if you're planting right along a walkway or a spot where kids run around barefoot, give it a little room back from the path. Nobody wants a bee encounter on the way to get the mail.
Before Next Time
Walk your yard and find one sunny, leanish spot where something's really struggling right now — that's probably your lavender spot. Bring a note on what's growing there currently and we'll talk about whether it needs to move.
