Sometimes called Velvet Groundsel, this plant has been living and marketed under several different names. The first name in the heading is the one Jimi Blake ascribed to it, a name I didn’t recognize for a plant I’ve grown off and on in the past…it got lost in his list paired with a particular Thalictrum and I simply missed it…until recently. I knew it as Senecio cristobalensis and, had I recognized it, would have included it with an earlier post in which I focused on his favorite Asteraceae. I did actually mention the plant there simply as another Senecio that I’ve grown of value. Here I shall treat it more directly. The genus, Roldana, was recircumscribed in 2008 to include some 54 different species. Other authors include as few as 48 and as many as 64 in the genus, most of which used to belong to Senecio and are native to the extreme Southwestern US, Mexico and Central America. Most of the Roldana species are somewhat ‘shrubby’ herbs with a few, like this one woody, even tree like. Both genera are within the Asteraceae and share tribe status as well, Senecioneae. For the curious, Roldana spp., even more finely, are included in the sub-tribe, Tussilagininae, which includes the very commonly grown genus of garden plants…Ligularia! On closer examination the morphological similarities will begin to stand out to most of us. Check out all of the photos on the Wikimedia Commons page for Roldana petasitis. Roldana petasitis is the correct species name for this plant. With all of the shuffling and consequent confusion still going on in the world of taxonomy, especially in such a mixed large genera like Senecio, we must all be allowed our mistakes of nomenclature. It is a volatile changing world out there. Continue reading
The title’s question isn’t something we in the Pacific Northwest need to worry about. It will take an awful lot of global warming to make this plant cold hardy here and that may be part of its enticement! I chose this from Jimi Blake’s list…because I am a sucker for cool foliage. Sometimes called the Mexican Tree Poppy this is a Poppy, a member of the family Papaveraceae, a family currently containing 42 genera and 775 species, which is within the the ancient order, the Ranunculales, an order that includes some of the earliest of the ‘modern’ Eudicots to evolve. This doesn’t mean that this species of Bocconia was around at the beginning of ‘time’, or even of this order, just that it comes from that particular genetic line, a line that has been traced back to its beginning, millions of years ago. Recall that every plant, every organism is in ‘process’, that given the appropriate supporting conditions, consistent over time, will keep reproducing, generation after generation…and, that given the appropriate inducements, of consistent, changed conditions, different from those today, will work to adapt to them, each generation ‘responding’, those better adapted, surviving and reproducing, altering the species and, perhaps even becoming, producing, a new one. One of the characteristics of this family and order, having arisen in a time when genetics and characteristics of plants were less strictly defined, is a wider range of physical or morphological variation than you might expect, which is evident when you look at the flowers of the many diverse species within these genera, this family and order…Bocconia frutescens’ small flowers looking very unlike those we would commonly think of when we picture a Poppy.

Loree, of Danger Garden, posted a comment and a link in Facebook a few weeks ago, to a story about a gardener in Australia and what gardening meant to him in the online Planthunter blog. It elicited an array of comments, both supportive and not. She posed the question, are the ‘best’ gardens the products of an ‘organic’ process, produced by the gardeners themselves, in intimate relationship with their place? Which raised the question, can garden designers create truly beautiful gardens for others on landscapes that they don’t have this personal connection to? Her question caused a flurry of comments, several containing a lot of emotion. Loree’s simple question produced a fair amount of ‘heat’. I found the array of responses, and the conflicts they brought to light, provocative and I think a lot of that heat comes from the fact that our modern society has become largely estranged from the natural living world. I spent quit a bit of time thinking about it. Below is what it prompted in me.
I retired from Parks after a career of mostly fixing and tweaking designs that I had nothing to do with, but ended up resposnisble for, tearing out neglected landscapes that had became grossly overwhelmed and out of balance by overplanted and aggressive plants, others that were lost to weeds and invasives, others still that were stomped out and abused by the public largely because of their siting and the public uses which they had to endure, a public that is often indifferent to the living world and its requirements and their resulting traffic patterns that designers thought that their massing could channel where they wanted. I did this while working within an organization that undervalued the plants and the horticulturists who cared for them….I was still able to create a few places that the public responded to positively.

Another Jimi Blake plant. I have history with this choice of Jimi’s…and the NW has a history with Bananas as well!
There’s an old hand colored postcard floating around the Washington Park office of bananas as part of an elaborate bedding out scheme around the ‘Chiming’ Fountain, near the Sacajawea statue. If memory serves, it is Ensete ventricosum, which have a uniquely identifiable form. Back in the day, Ensete v. seems to have been a thing. It is a non-suckering species, unlike the spreading, mat forming Musa spp. and cultivars, and is commonly grown from seed. It is interesting to me that they were available prior to the 1900’s and relatively common, probably up to 1929 and the stock market crash…at least for the more horticulturally involved, as specimen in annual display beds. Gardeners must have dug them out in the fall and hauled them to greenhouses to ‘protect’ them for use in the following year. I did some research in the early ’00’s of catalogs and area nurseries to get an idea what was available in the 19 teens, and of a few Park’s planting plans of this period, influenced by the Olmsted’s and under the direction of Emanuel Mische…. Compared to typical planting plans of more recent years these were relatively adventurous, especially given that acquiring such plants was often a much bigger deal in the nineteens and twenties than it is today. Back then if you weren’t wedded to a particular clone and you could find seed for it, exotic bananas were a possibility. There was an excitement around the novel and exotic that had spilled over from Europe. Local inventories also included a wide array of bulbs which could be more easily shipped than grown plants widening the range of choices. They often times had choices that you would have to spend some time searching for even today. With the economic collapse of ’29 it is no surprise that tastes and possibilities became much more conservative. There were those who clung to the use of some of the old exotics, but you would have to look hard for them in public places and gardens. Botanical gardens became refuges for the forgotten and newly collected. It took many years before enough of the gardening population reclaimed their sense of wonder and awe enough to create a new market for the plant’s of the world. We experienced a similar contraction of the nursery industry in the Fall of 2008 when the real estate boom stalled and demand for plants collapsed causing the closure of many nurseries and a reduction in the selection available from local garden centers. Locally gardeners have become increasingly interested in such plants and have continued to support the many small specialty nurseries that provide them Continue reading
Another Choice Plant From Jimi Blake’s NPA Seattle Study Weekend Presentation
‘El Rayo’, in english is, ‘Lightning’! One should expect something pretty spectacular, flashy even, with this plant…or not. ‘El Rayo’ in Portland is a taqueria!…in Portland, ME that is. I would hope that the name of either doesn’t over sell their product! Does anybody know? About the tacos I mean? Gardeners should always be wary of cultivar names. While they serve as identifiers of a particular, and allegedly unique form or clone, and sometimes as a helpful and memorable descriptor, they can too often tread across the line into misleading hyperbole! Names are often assigned to a plant that have been in the trade for some time under other names. These ‘new’ and unique names are then ‘trademarked’, legally protected, as the nursery heavily markets the plant. The gardening public then comes to recognize and associate this protected name with the plant and begin to ask for it by that name. Unlicensed growers cannot supply the plant by that name and so some nursery producers carve out a larger share of the market. After experience we may come to recognize these marketing ploys…or not. Oft times a little celebration or indulgence is called for. Continue reading
It would seem that gardeners are a difficult lot! For those of us intent on gardening with ornamental plants we are continuously drawn to the exotic and novel, sated less and less by the plants in yesterdays’ garden…at least until those have had suitable time to have fallen out of fashion and are rediscovered. For most of us it is the plants we’ve never grown, or even seen before, that draw us. This is as true when we ourselves are novices as it is many years later. Sure, we all have more than a few long term relationships with particular plants, but we seem forever subject to the seductive calls of the unknown (to us)! For many of us this is at no time more true than when nurserymen, on the ‘cutting edge’, and plant explorers come to town, especially if they come bearing pretty pictures…Even mores so when paired with the opportunity to acquire them. Instant gratification. It is a conspiracy you know. Continue reading
I can’t get Jimi Blake’s HuntingBrook Garden out of my head…that’s a good thing, though a little odd since I’ve never been there. The images and ideas, the energy that both Jimi and his sister, June, who gardens nearby, projected at the NPA Study Weekend was infectious and inspiring. Their gardens are both beautiful and, obviously, central to each of their lives. They are dynamic, like the minds of each of them, endlessly creative and curious…botanical dabblers of the highest order. Apparently, their gardens don’t stand still. No plant or bed is ‘safe’ from revision, in part or from wholesale revision. I have no pictures, their’s, however were gorgeous and seductive. I have to rely on the few they have posted to their websites. Please, go to them. (Jimi’s HuntingBrook Garden.)
Of the two, Jimi spoke first, his topic, Salvias, those that he’s found to be worthy of a place in his garden. With such a relatively large garden he can ‘trial’ many plants, and, if you’re like Jimi, evaluate them in terms of both aesthetics and performance. He loves Salvia…there are nearly 1,000 species and who knows how many hybrids and selections! He grows many from seed, others he’s rooted from cuttings, like minded Salvia-philes gift him with treasures and Jimi works them into his beds, artfully. You won’t see any sterile lab like rows, he trials them in mixed borders and beds. In Seattle he presented his ‘winners’, 33 different species, hybrids and selections. The list is comprised primarily of plants ‘durable’ enough for his conditions with long bloom periods…with a few exceptions, late bloomers, and those of short duration…need not apply. Continue reading
