We just snapped this photo of Lemon Thread Cypress (Chamaecyparis pisifera 'Lemon Thread') in the gardens here at Juniper Level, and wanted to share since it illustrates our constant rants about trusting nurseries, plant tags, and websites to give accurate mature sizes. For a woody plant, our typical advice is to triple any size you are given. So, we wanted to see how that advice would work with the plant below.
Lemon Thread cypress was discovered in the mid 1980s as a sport at Oregon's Mitsch Nurseries, so it's a relative newcomer as plants go. Our 20 year old specimen is planted in compost-amended sandy loam without any chemical fertilizers ever. We should also add that we don't believe in shearing plants, which we find a waste of energy as well as a middle finger to natures's beauty. Our specimen now measures 25' tall x 15' wide.
We then searched the web for Lemon Thread Cypress and recorded the sizes from the top 30 sites that came up in Google...see notes below the photo. Sizes Read more [...]
We are rightly skeptical of great new plant claims, since so many new introductions fail to live up to the marketing hype, so we were cautiously optimistic when we planted our first trial plants of Helleborus x glandorfensis a couple of years ago.
These new, thought to be impossible hybrids of Helleborus niger x Helleborus x hybridus, have indeed lived up to the marketing hype. They are similar to the incredible Helleborus x iburgensis hybrids, which preceded them (crosses of Helleborus niger, hybridus, and lividus), but without Helleborus lividus, which produces the leaf veination, but reduces the flower size slightly.
The H. x glandorfensis hybrids (created by breeders in Glandorf, Germany) have dark, black green foliage, with flowers which are ridiculously large for a lenten rose.
Both the H. x glandorfensis and the x iburgensis hybrids have outfacing flowers and do not produce seed. You can't go wrong with any of these amazing hybrids for the winter garden!

Even though we're in the garden virtually everyday, there's so much to see that we often miss things that are right in front of us. Case in point...a few weeks ago, our taxonomist, Zac Hill was walking though the woodland garden and noticed that our evergreen Solomon's Seal had been sexually frisky with another disporopsis species in a nearby clump. In the photo on the right is the daddy, Disporopsis pernyi, and on the left, the momma, Disporopsis undulata. In the center is the baby...a hybrid between the two.
The hybrid clump was actually fairly large, so we'd missed the blessed event by several years. According to disporopsis guru, Dr. Aaron Floden of the Missouri Botanical Garden, this seems to be the first time that anyone has documented a hybrid between these two species, so we named our new baby Disporopsis 'Opsis Attract' and look forward to being able to share in a few years.
In addition to spring, one of the things we look forward to most each year is the members only seed exchange list from the North American Rock Garden Society.
This amazing list of plants, shared by members from around the world, is truly the place to find seed of rare, hard-to-find plants for rock gardens and pretty much any kind of garden. The seed list typically offers 3000-4000 different plants annually...probably the best in the world. The first round of distribution in January of each year is limited to 25 different seed types (35 if you donate seed), and the second round, which just went live, allows members to select another 100 varieties. We just got out order submitted, and now anxiously await their arrival.
We think the seed exchange alone is worth far more than the annual dues, but there's so much more from tours, to meetings, to networking, and a great journal. So, if you want to become a seedaholic, here's your path to addiction!
