Salvia azurea (maybe my favorite salvia in the world — sky blue flowers in late summer/fall, hardy to zone 5) is blooming in the garden, and the bees are all over the flowers. But while some are poking their heads into the flowers to drink nectar and transferring pollen as they do so, others are up to something more sinister.
The evidence of what they are up to is clear if you look closely at the side of the flowers after they leave.… Continue reading this article “Robbers in the garden”
I’m going to keep posting about perennials that deserve more attention until somebody makes me stop. The fact that my subject is, once again, yellow… is merely coincidental
Definitely was a crowd favorite during the Perennial Plant Association annual Symposium’s grower tour (mentioned in my previous post). These photos were taken at Emory Knoll Farms north of Baltimore; I believe that they were trialing and/or including it in their plant selection for green roof use.
Thanks to Mary Vaananen, Jelitto’s North American operations manager (and goddess of perennial plant knowledge), who just happened to be standing next to it, full of 411, when I squealed “WHAT the (blankety blank) is THAT?!”… Continue reading this article “Perennial Funday: Eriogonum allenii ‘Little Rascal’”
I spent last week in Orlando at the ISA annual meeting (that’s the International Society for Arboriculture). It’s a great venue for networking with colleagues and hearing about the latest tree research. And once in a while I’ll have a WTF moment. (That stands for Why Trees Fail in case you’re wondering.)
My WTF experience this year revolved around some new terminology and techniques. I learned there are now “environmental arborists” who practice “retrenchment pruning.” In the last few days I’ve tried mightily to find some standard definitions from reputable sources.… Continue reading this article “A new excuse for bad pruning”

A few weeks ago I made my way to South Dakota for the annual meeting of the National Association of County Agricultural Agents (where fellow GP and I made the rounds at the trade show scrutinizing wacky products). It is a fun conference made even more special this year by the fact that WVU President E.… Continue reading this article “Pollination strategies can lead to allergy woes”
I thought today’s post would feature two awesome plants that are relatively new or unheard of in the industry. Both of these plants have performed well in my own garden and survived our two hardest winters recorded since the 1970’s. Many plants suffered severe winterburn or even death due to extremely low temperatures, but not these two plants. They may be harder to find in the nursery/garden center, but are well worth it and have huge ornamental impact all growing season.… Continue reading this article “Cool Plants for Late Summer”
Sometimes where you shop matters, because if you buy plants at the wrong place you run the risk of importing new problems into your garden. Those cheap plants you grab on a whim sometimes are far more trouble than they are worth.
I learned (or relearned…) this the hard way last year when I grabbed a bag of super cheap gladiolus corms at a box store. They were cheap, and pretty… and infested with gladiolus thrips.… Continue reading this article “Don’t buy problems”
I believe I’ve spent approximately $1,000,000 on seeds over the years. Plant and seed catalogs are usually addressed to “Gullible L. Scoggins.” I really suffer (on many levels) during the darkest days of winter; this makes me highly susceptible to seed catalogs filled with delicious descriptions and enhanced photos.
This spring, I sorted through my massive bin of partially used seed packets and ruthlessly (ruthlessly!!!) chucked everything dated prior to 2012 (like normal people do). A large portion of the expired packets were for squash and zucchini.… Continue reading this article “Just like it said on the seed package!”
Sometimes it’s fun to experience life unfolding around you. This past week I started my new position as the Director of the UNC Charlotte Botanical Gardens and am very excited to be working with my old friend (she’s not old – I’ve just known her a long time) Paula Gross, Assistant Director of the garden, a fantastic horticulturist, and one of the best people you could ever hope to meet. Together with our highly skilled staff we’re going to be working to bring the world of plants to people.… Continue reading this article “A Brief Announcement”
I’m not a fan of using corrugated cardboard as a mulch, which like other sheet mulches creates problems for the underlying soil. Long-time readers of this blog may remember several previous posts (1, 2, 3 and 4) on this topic and I won’t belabor the points made in those posts. Instead, today I’m doing to focus on cardboard itself.
First, cardboard is a generic term that can refer to many types of manufactured paper.… Continue reading this article “The cardboard controversy”
The subject of Genetically Modified Organisms, or GMOs, first came to my attention sometime in the fall of 2009, not long after I started following the Garden Professors Blog.
I stumbled across a site called Biofortified, run (at the time) by a couple of grad students in the field, who were trying to accomplish the same thing that the GPs were, combatting myths and misconceptions about a subject, with research based information.
I spent about 2 years lurking there, because much of the information at the time was over my head, and seemed to be targeted to fellow scientists to help with getting the information out.… Continue reading this article “FrankenFoodFacts”
