I am embarrassed to complain, given what the people in Boston have endured this winter, but I will say it.  We have had a long tough winter. We had the better part of Boston’s snow last year. This year, no heart or record breaking snow, but plenty of snow nonetheless. The snow I could plow through, and shrug off. The tough part was an interminable run of very cold weather, lots of it below zero. Dressing for a trip outdoors was an event the likes of which was almost intolerable. Boots, gloves, coat, hat, and lots of layers in between. All of this piling on took lots of time. That effort did not come to much good-the cold was bone chilling.  No one took the arctic winter poorer than the corgis. Every day they would plead with me to change the channel. They were bored and irritable. It was a daily thing, wanting to be let out every possible door to the outside-in hopes one would reveal habitable weather.  The spring in Michigan does not come easy or in an orderly fashion. Mother nature takes her time, deciding when the season will change from winter to spring. We have been made to wait.

We feel better about the weather, having worked to introduce our own indoor version of spring. In March, we take delivery of over 1000 hellebores from growers all over the US and Canada. We invite gardeners in our area to come, browse and review our collection, and speak for them. We mean to offer gardeners a respite the winter, with our hellebore festival. It takes a few days, but our greenhouse space is starting to look like and smell  like a garden. Our March weather seems to be moderating-we have hope we are on a track to spring.  But if the spring outdoors is practically still weeks off,  we have a version of spring in our greenhouse. Should the spring be a few weeks off, the hellebores are content to reside in  sunny window until the ground outside can be worked.Hellebores are a hardy perennial in our zone. Many of them are hardy in zone 4; most of them are eminently hardy in zone 5.  I treasure them, as they are the first perennial to bloom in my garden in April.  Hellebore foliage is large, and will persist long past the fall and into the winter. In warmer zones, the foliage is evergreen. The Orientalis hybrids throw their bloom stalks very early in the spring, arising out of the declining foliage from the previous season. The new foliage which is to come after the blooming is lush and substantive. They are tolerant of a wide range of conditions in the garden. I grow them in full sun, but I water them when they need it.  They are equally as happy in a lightly shaded location. They can live and increase in a garden for many years, without any need for division. Deer do not touch them. The flowers are surprisingly large, and quite beautiful.

The flowers of the hellebores my Mom grew in her garden 50 years ago did not look like these. The blooms were nodding-down facing. To enjoy her bell shaped flowers required getting down on the ground to look up into their faces. She would cut them, and put them in a vase in the kitchen window.  Her favorites were the white and green flowered hellebores, as the pink cultivars were a muddy not so appealing pink.  It took years to grow on a hellebore to a decent size, as they were only available as young starts.  There was always lots more foliage than flowers. Nonetheless, she loved the look of them in her shade/wildflower garden.  Their foliage would last the entire summer and beyond, unlike the spring bulbs and ephemeral wildflowers she cultivated. The hellebore world has changed dramatically since then.

This group of plants have been the subject of intense breeding all over the globe. A lot of attention has been devoted to breeding plants who flowers are out and up facing. Some breeders have produced strains of hellebores with double flowers, or unusual coloration. Marietta and Ernie O’Byrne, who own Northwest Garden Nurseries, have bred some stunning strains of hellebores.  The same can be said for Judith and Dick Tyler who own and operate Pine Knot Farms. These names are just two of a long list of hellebore enthusiasts who breed and sell plants in Belgium, Germany, England, Japan, the US and Canada.

Most of the plants in the greenhouse are hybrids of helleboris Orientalis. Helleborus Orientalis is not a species of hellebore, strictly speaking. It is a plant which is an interspecific cross from a number of different species hellebores-the O’Byrnes think maybe more than 16 species have a part in what is properly known as helleborus x hybridus. They do not come true from seed, so many of these named varieties are referred to as such and such “strain” of hellebore.  Given that the plants may take 3 years to flower, many breeders sell their young plants with pictures that show the possible color range. The advent of tissue culture has made it possible to clone specific plants, and make them available to interested gardeners.  My discussion of the history and science is quite limited-for a detailed look at hellebores, do visit the website of Plant Delights Nursery. Some of the hellebores we have came from a trip Rob made there a few weeks ago.  Tony Advent does a terrific job making great garden plants available to serious gardeners.  He also does a great job of providing an overview of the history and proper culture of the plants he sells.

The hybridizing of hellebores to produce stronger growing and beautifully flowered hellebore cultivars has been a shot heard round the world. Today, hybridizers in Europe, Canada, Japan and the US have created cultivars featuring study and garden worthy plants, and breathtaking flowers. The vast majority of the plants we have available now are cultivars that have a proven performance record. And we feature large sized plants that are old enough to produce a good crop of flowers from the start. But we also have a limited number of one of a kind plants that would appeal to a hellebore collector.

I did buy a collection of named hellebores last February from a nursery in British Columbia, Canada, named Fraser’s Thimble Farms.  They ship small plants to the US, bare root. I did have to pot them up, and baby them along in the window sill of my drawing studio until they took hold. I finally planted the entire lot of them in a patch in my garden that used to be occupied by some not so wonderful looking yews. Just yesterday I could see that the snow had melted, and all of those small plants look like they survived our winter. I am not expecting all of them to bloom this spring, but I have hopes.

We do have gardeners come in who are not familiar with hellebores. This is not so surprising. Some nurseries are reluctant to carry plants that take 3 years to flower from seed, or are already out of bloom in May.  The good news for gardeners is what appears to be the flower is actually a modified calyx, or petal like structures that surround the actual flower. The flower is in the center, and these true petals will drop when the flowering period is over. But the calyx persist on the plants for months, giving the appearance of a really long bloom time. Still, I try to site hellebores in spots that make them easy to view in early spring.

Hellebores also make great container plants.  Everything we ordered for our collection is in, and our Hellebore festival is slated for Friday March 20 through Sunday March 22. Can you come ahead? Of course.
