Santa Fe Botanic emailed me recently and asked how to define and categorize some plants into their database, which I grew, and which Lauren Springer used in the memorial garden for David Salman. These are the "Aloinopsis hybrids" gleaned from friends and then re-grown and bred myself for some years.  Answering the question leads to a brain-twisting philosophical discussion I wanted to share with you that I've been mulling on for the last year. What are the "Aloinopsis hybrid" plants?  " Well, it's a complicated answer: Those plants are truly unknown in exact species, and ..read more

Thanks to Grace at DBG and PlantSelect. If you know anyone new to this, which is basically essential in rock gardening and dry/native plantings, please pass this on to them.  If you aren't a believe, try it. I dare you. Pink flip-flops optional ..read more

  This is a competition. Plants will be judged for ten years on three traits: -Longevity -Rebloom -Sex appeal  (to everyday people  and not botanists or nerds like me.) This means these three winning plants will be ideal for  No-water Landscapes;  places where they can't hide in an ugly season.  1. Gaillardia 'Amber Wheels' The problem with allllll the other gaillardia is that they are barely perennial, living 1-4 years at best, but often just a couple. This one, selected from the wild in Colorado by DBG's Larry Vickerman, is FULLY PERENNIAL, and what's mo ..read more

 Back in 2013 I started working for myself, and started hiring employees, with a nearly religious mission to make landscapes that use natives and need no water. ...And that get better with age and do ecologically good things, et cetera. Over the years, my landscaper era waxed and waned as I felt drawn to address crevice gardens and work away from my semi desert valley. But the mission remained. (circa 2015, those were honest times...) More recently, Especially during Covid, I found myself working increasingly as a "coach" for homeowners who were DIY xeriscaping their homes because of a ..read more

 Several friends' inquiries made me realize this was needed. So here it is.  These are species I have grown without irrigation, in crevice. I am sure there are more. There are a few things that seem to require being in either/both crevice and unirrigated.  Know that a "rock garden plant" is subjective, and usually comes down to size and habit being appropriate with your rocks. Plenty of these are too large for a small crevice garden with small rocks and are noted as such. As with any unirrigated garden, performance and show will vary with rain and weather year to year ..read more

NARGS Rocks: Rock Gardening Does Meadows A webinar hosted by Kenton Seth.  Feb 19: 10:30am-4p, MST  Yet another in the varied, successful, and wonderful series created in the last year by NARGS, I am hosting the meadow-garden themed webinar. I am stunned by the caliber of speakers, and especially excited to expose listeners to a few certain folks whom I’d call sleeper talent- amazing geniuses perhaps not known in wide circles.  A meadow is not a new idea- arguably the classic border and cottage garden is a meadow- it’s really any garden dominated by herbaceous plants. But rece ..read more

Ipomoea leptophylla, five years without water. In context of establishing great plants into gardens, I have come to know a certain motley crew of remarkably unrelated and excellent plants that all seem to have the same problems- problems which may explain some of them being so absent in gardens. Lassoing them into a group in my mind has made it easier to deal with their funky personalities, and so I want to tell you who they are, and my trick to skipping the bull and enjoying them at their best. -Most hate transplanting- some usually die from it. -They have significant taproots, often hate ..read more

  There has been discussion among rock gardeners, roof gardeners, bonsai growers, and the crevice people about sourcing expanded shale and other permeable aggregates. These materials are like porous gravel, holding water and nutrients without organic material- which is very useful mixed into crevice garden soil media and in containers to grow alpine or rock plants. Here is a list I've been compiling: Haydite (Ohio)  Seramis (Germany/Europe/UK) Permatill (by Stalite) North Carolina Turface (actually calcined clay) or “Pro’sChoice” brand Trinity Expanded Shale (Golden ..read more

 Ever find out something about a plant that sure as hell isn't in the books about them? Like Gaillardia 'Amber Wheels' being rhizomatous.  Oh yeah. Surprise #1 Hard-blooming Gaillardias are anything beyond a short-lived perennial. Usually you get seedlings off the mother plant before she dies. But last year, when I was planting bulbs in a high elevation flower bed designed by Scot Ogden, I saw shallow rhizomes everywhere. I keep an eye on that bed to keep certain nasty rhizomatous grasses out. But these white threads- I followed them back to the plants. Whaaaaaat? I emailed Scot to f ..read more
