Introducers of new century plant selections are challenged with coming up with appropriate cultivar names, often have a propensity to use wordplay, referring to the agaves spiny teeth. Two favorites, we photographed this week are below, Agave titanota ‘Snaggletooth’ (top), and Agave titanota ‘Sabertooth Tiger’ (bottom). Both are mutations of the same original plant, the later was derived from a mutation that flipped the pattern from an edge to a center. Agave titanota is prized as a summer patio container plant due to its relatively slow growth rate. Plants must be stored indoors for the winter when the temperature drop below 40 degrees F.
Looking lovely today is the amazing Agave x romanii ‘Shadow Dancer’. This fascinating agave is a man-made hybrid between two Mexican species, Agave filifera and Agave mitis. Not only is it a hybrid, but this selection has a fascinating variegation pattern that’s not seen on any other century plant. The new growth emerges ghostly cream with a muted green border. As the leaves age, they green disappears and the leaves become pure parchment white. Despite the seeming lack of chlorophyll, Agave ‘Shadow Dancer’ has amazingly good vigor and doesn’t burn in full sun. This has potential winter hardiness for Zones 8b and south, but needs more trialing to know for sure. In other climates, it’s a great container specimen.
One of our favorite love lilies in our 2003 introduction, Amorphophallus konjac ‘Pinto’. This amazing dwarf never has foliage that exceeds 16″ in height. Unfortunately, the ridiculously slow growth rate has kept us from offering it again since, but perhaps one day. Here is our parent plant in the garden this week. Even if you don’t have a home garden, this form is superb in a container. We had a large crop of dwarfs from seed two years ago, and are looking for more unique new compact selections.
We’ve got a thing for hardy cactus in the garden, but haven’t propagated many to offer yet. One of our many favorites is Notocactus apricus. Above is our 17 year old clump in the garden, which is 4″ tall x 15″ wide. We’ve grown a few from seed, but are curious how many folks might consider purchasing one? We’ve only been to 7F since 2000, so we don’t know if it will take colder temperatures or not.
Visitors to our spring Open Nursery and Garden this year got to see the amazing Trichocereus ‘Irridescent Watermelon’ (bred by local cacti specialist, Mike Papay) in full flower (hardy so far to 7 degrees F). Offsets are almost non-existent, so we decided to grow some from seed. Each plant will be different, but all should be quite nice. So, if we offered these as a seed strain, would you purchase some, knowing each will be slightly different?
Also flowering now in our rock garden is Drimiopsis maculata ‘Slow Fade’…having come through our cold winter with no problem. Hardiness is Zone 7b-10b, but it makes a great container specimen in colder zones. I think this is one of the cuter plants we grow in the rock garden, and so very easy!
