1 Agaves in vogue These spiky shrubs strike a pose wherever they re planted, and sales are spiking, too Agave Blue Glow features blue-green leaves with red margins edged in yellow. Each leaf tip bears a short, soft red spine. Photo by Sean Hogan By Tracy Ilene Miller Despite their many fine attributes and fitness for a wide range of zones, agaves in the landscape have yet to be fully embraced by gardeners and landscapers. Perhaps it s their prickly constitution. Large-scale acceptance may be just around the corner, however, as nursery growers of these architectural beauties have seen sales of agaves steadily increase the past few years. It s not a huge market, but we ve noticed a slight uptick over time, AUGUST 2013 DIGGER FARWEST EDITION 13

Photo courtesy of Little Prince of Oregon Nursery said Ketch de Kanter, owner of Little Prince of Oregon Nursery in Aurora, Ore. Sean Hogan, owner of Cistus Nursery in Portland, Ore., agreed. It s coming along, he said. People are more savvy about the hardy ones and which ones to leave as house plants. Agave has wide variability in hardiness and size. Oregon growers are building up their inventories of mostly hardy varieties down to USDA Zones 6 and 7, along with a few of the tender ones, more suited to Zone 9. Hogan s love for agave stems back to his teenage years and has seldom abated. At times, Cistus Nursery has sold more than 100 agave varieties, leading the staff to nearly revolt, Hogan joked.

3 in the tender category. Little Prince of Oregon Nursery sells nearly 30 varieties; almost all are hardy in the Northwest. Blooming Nursery in Cornelius, Ore., offers about the same number of selections. The wholesale grower, specializing in perennials, has been growing agaves for nearly five years. The first year or so was very slow, but now they are selling at a good rate, sales representative Jim Siehl said. They are something that people are willing to play with, especially when plant stores are willing to pot them up. #6 and 3/8-1/16 horticultural Educating the consumer Retail customers can be roped in when they see agaves displayed in pots, and it s especially true when they re mixed in with plants that complement their chiseled features. This is where the agave learning curve should be taken into special consideration. According to growers, consumers need proper and specific growing information to go with the plants. Otherwise, they are less likely to experience success with them. Retailers should be Agave schidigera Black Widow is prized for its unusual silver-white threads that develop along the leaf edges as the plant matures.

4 AGAVES IN VOGUE Agave ferox makes a handsome landscape subject as well as a great container plant. When it flowers, the stalk can be 30 feet tall with 3-inch-long yellow flowers, which attract hummingbirds. Photo by Sean Hogan particularly mindful of agave s placement with other plants in store displays, growers said. This will further associate the plant with its appropriate placement in the landscape. I would practice caution what you put agaves with, Hogan said. For instance, display Japanese maples around the corner with some of the wet-weather, overly green stuff. Position agaves with other plants that showcase their drought-tolerant nature and sculptural, strong shape. The most important thing is to keep their feet dry, de Kanter says. It s not really the issue with cold up here; it s the issue with dryness. Very little water is required after you establish them. They look great in a rock garden and for xeriscaping, as an alternative to Sempervivum and Sedum. Agaves look great in pots, espe- GROW YOUR BUSINESS NOT YOUR ENERGY COSTS Energy costs are rising, so it makes more sense than ever to invest in energyefficient greenhouse and nursery equipment.

5 cially in groupings. As the main attraction, their bold rosettes contrast with other low-water plants such as Oenothera berlandieri (Mexican Evening Primrose), that will ramble through, Siehl said. Other good companion plants for agaves include Cerastium tomentosum (Snow-in- Summer), Epilobium canum (California fuchsia) and varieties of allium such as Agastache and Cistus. [Agaves] are so architectural that they can be used as a focal point in the garden, especially in the drier garden with lots of sun, or a focal point with other things in a pot, Hogan says. They are like hens and chicks on steroids. It almost goes without saying, but every agave sold at retail should come with a warning that the roots need to be kept bone dry. But customers also should be advised that these plants have sharp points that can poke them. Plants aren t normally intimidating, de Kanter said with a laugh. But agaves can hurt you. It could be a limitation to sales. Native to southeastern New Mexico, Agave neomexicana is one of the most cold-hardy agaves. Photo by Sean Hogan AUGUST 2013 DIGGER FARWEST EDITION 17

6 AGAVES IN VOGUE Slimfoot century plant (Agave gracilipes) has a compact form and leaves that unfurl to around 12 inches long.

Hogan, de Kanter and Siehl pointed to several favorites. Hogan recommended Agave Blue Glow, an all-around best seller. One of the reasons for its popularity could be its smooth foliage. Its redtrimmed leaves are vibrant and attractive, and its blue color glows almost translucent in the afternoon sun, where it s best situated. Hogan recommended two others that are especially good for newbie agave growers, because they re hard to kill. They are Agave parryi var. couesii, which is one of the smaller and more cold-hardy selections of A. parryi, and the equally cold-hardy Agave neomexicana. They re very blue and form little rosettes two feet across. Hogan said. They re fun, and I ve seen some of them in my neighborhood, in old rock gardens. Agave parryi Cream Spike is another compact rosette type, and a grower favorite (although still a surprise underseller), with its smooth leaves, 18 AUGUST 2013 DIGGER FARWEST EDITION

7 Dark brown teeth and spines contrast with the cream-edged green leaves on Agave Cream Spike. The small rosette-forming succulent grows to only 4 inches tall by about 6 inches wide, making it a great container plant.

In the larger varieties, Agave americana var. protoamericana Silver Surfer is one of the more popular grown as a specimen, to 5 feet. Its stiff, silvery-blue leaves command attention as they point to the sky. It has the century plant look that people think of when they think of agave, Siehl said. For customers looking for hardy and big, Hogan recommended Agave ovatifolia Whale s Tongue. It can reach 7 8 feet across. According to Hogan, AUGUST 2013 DIGGER FARWEST EDITION 19

8 AGAVES IN VOGUE Also called weeping agave, Agave tenuifolia is a small, clumping species with slender, arching leaves that grow to about a foot tall. Photo courtesy of Little Prince of Oregon Nursery it s one of the most frost and damp tolerant, agaves with a green the color of a jade necklace. Although you could put it in a container, it demands space outside of one. The spikiness of agaves may deter particular customers, but it hasn t stopped varieties with a particularly sharp presence from reaching the top of sales lists. I would have thought just the traditional ones would have sold, but it s across the board, Siehl said. I m surprised that there is a wide range of demand for agave. We haven t dropped anything for lack of sales. Agave gentryi Jaws, for instance, is a consistent seller. Named after the famous movie, the leaves on this short (under 2 feet) agave are curled in and look like they are lined with shark teeth tinged in red.

9 Just as menacing sounding, and as popular, Agave parrasana Meat Claw is another short plant with a sharp presence. It matures slowly and sports powder-blue leaves that look as if short fishhooks edge them. Another surprise, de Kanter said, is the number of his plants going to California. He had assumed the growers there would meet the demand of the California market. But consumer demand there is evidently higher than the supply. The fact that agaves are slow growing might be a factor. This limits the availability of stock in the trade. What s more, reliable sources for tissue culture material are limited. Because of these conditions, prices tend to stay high and inventory low on any one variety, even as demand for agave is rising. For instance, de Kanter is almost up to one greenhouse full of agave, but because it is slow growing, a single variety may actually be in five stages of production in one house. Considering their beauty, their strong form in the garden, and the increasing interest, growers are continuing to explore and expand the range Using Our Pots Can Also Lift Your Bottom Line!

10 AGAVES IN VOGUE of varieties that are hardy and well suited for the Pacific Northwest and beyond. Little Prince has gone so far as to market some of the agaves as part of the outside-inside line of plants: those that can be grown outside and brought inside. By accident de Kanter discovered his Blue Glow was doing well, which led to testing of others, and now they have six they sell in ceramic pots as outside-inside plants. He imagines many more agave varieties will prove their resiliency and versatility over time and once tested. Agave ovatifolia (Whale s Tongue Agave) grows from 2 to 5 feet tall by 3 to 6 feet wide with a rounded rosette of wide gray leaves that are distinctively cupped.
