Winter Hellebores as cut flowers and how to make them last

A plate of hellebores from Northwest Garden Nursery

March is peak Hellebore season for us in the Pacific Northwest and there's so much to love about them in the garden, but the temptation is ALWAYS there to cut them to bring inside for a vase. The trouble is, once hellebores are cut, they often have a hard time actually taking up water and in a matter of minutes, their heads are drooping and look unflattering. So to enjoy them, most people will just float them in a shallow platter like the O'brynes did above.


First, I want to write about the different types of hellebores one would encounter at a large garden center. There are two main types that are distinguished by their growth habit:  stemmed (caulescent) or stemless (acaulescent).

Caulescent types emerge from the ground and have a prominent stem with attached alternating leaves and the clusters of flowers up top. H. argutifolius is an example (the green ones in the photo on the right and all the foliage you see is attached to the main stem with the flowers up top)


Acaulescent hellebores do not form a stem with foliage, but instead, all the foliage and flowering stems emerge from the base of the plant. The "orientalis" type of hellebores are the most common. (the pink flowered ones on the photo)








Now, between the two basic growth habits, there are hybrids between the two types creating varieties that possess some of the qualities of both resulting in vigorous and hardy garden plants.

Helleborus x ballardiae 'Pink Frost'

I've found that all types of hellebores have a difficult time standing up when cut for a vase. There are many tricks that have proven to be effective such as:

1. Dip cut ends in hot boiling water for a few seconds.

2. Flame the cut ends for a few seconds to supposedly "seal in" the moisture

3. Slice bottom end lengthwise an inch or so to maximize water uptake. (Mentioned by Val Easton on her blog. She wrote a book called "Petal & Twig")

4. The age of the flowers play a very important role in the longevity of a cut hellebore. Wait until the ovary begins to develop when the stamens, anthers and nectaries have fallen off and the flowers are a little "greener" and they'll last for about 10 days when cut (according to Diane Szukovathy of Jelly Mold Farm)

I've primarily been playing with the "Orientalis" types (very uncommon to get the true Helleborus orientalis species). They are botanically referred to as Helleborus x hybridus because they're far more plentiful in bloom along with some of the complex hybrids out there like 'Pink Frost' above, 'Merlin', and 'Cinnamon Snow'.

So recently, I chatted with Linda Beutler at the Yard, Garden, and Patio Show in Portland, Oregon who wrote the book, "Garden to Vase: Growing and Using your Own Cut Flowers."

 
Linda advised me to try the following solution to condition Hellebores for arranging:

2 tablespoons of alcohol to 1 quart of regular tap water 
1 packet of flower food (optional)

Keep Hellebores in a cool location as they soak up this solution overnight (I never found out how long, this is how long I soaked mine, but it's probably less than that) and then they'll be ready for arranging.


So, I used a combination to maximize the longevity of these precious cut blooms (and also to tell each of the people I've consulted about hellebores that their technique worked! LOL!)

I've noticed that Hellebores need to be kept cool and hydrated as if they've never been cut. So, I bring a bucket of water out to the garden that will have at least half of the cut stems submerged.

As I select stems to cut, Linda recommended that one should wait until the very first bloom to mature (meaning having the stamen, anthers, and nectaries naturally fall off). Diane will wait for all flowers to loose their central bits. 

Then I used Linda's solution to condition the flowers and remarkably, they stayed perky and held up pretty well for 2-3 days inside the house. Then I noticed a few things:

1. A few wilted sooner than others.
2. Re-cutting the stems seems to "uncondition" them.
3. The shorter the stems (mostly submerged in the water, the longer they seemed to hold up. 

A bright and gorgeous Golden Sunrise hellebore just cut from the garden. Noticed the first flower to open and mature at the bottom.

Split the cut end to maximize water uptake

Immediately submerge in fresh water or in a conditioning solution.

CONCLUSION:  This alcohol solution seems to work and is simple, cheap and highly effective if flowers are harvested at the right stage. 

*2 tablespoons of alcohol to 1 quart of water and a packet of flower food if you have it.

*Always keep them as cool as possible (again as if they weren't disturbed by being cut) and the shorter the stems, the better.

*The "green" varieties seem to hold up much better than the others.

And no, I'm no afraid of heat or fire, I just haven't gone that route because I have an issue of physically damaging plant tissue when it might not be necessary.

Debra Prinzing, author of "Slow Flowers", with split-stemmed, alcohol/flower food conditioned hellebores from UW Botanic Gardens/Washington Park Arboretum she took with her on a plane to New York to help promote American grown flowers for a very special wedding! They held up VERY WELL and designers drooled and fought for them!

Can you spot the hellebores??  Arrangement lasted about a week in a cool room indoors and the Akebia vine opened is scented blooms!

A very tiny centerpiece with a "conditioned" hellebore that lasted only 1 day before it curled up. Maybe if I used an "older" bloom.

Pink hellebores with flowering currant (Ribes sanguineum). I kept this arrangement outside. Most of the conditioned Hellebores held up for about 5 days, but one variety in the foreground is still "plump" after about 9 days.

A very short arrangement using parrot tulips and the bloom head of H. argutifolius which did not hold up as an entire stem when conditioned and put into plain water inside the house. So I cut the flower head, conditioned the short stem in the alcohol before arranging this and they still look good after 8 days.

Again, shorter stems hold up longer and you can use lovely grape hyacinth with them!!

More hellebores and Muscari latifolium

Black hellebores with the silver/green cardoon foliage is stunning together with sprays of Osmanthus delavayi for fragrance

Older blossoms of 'Pink Frost' hold up well and much longer than the delicate Epimedium in the foreground

 

Green and chartreuse mean SPRING!!

"I'm ready...." it says...

Garden Shinanigans in Oregon Part 3: ID'ing the Unknown (Like, I'm suppose to know?)

So, here's a little clip I took of the guys wanting to show me something at Ernie and Marietta's garden at Northwest Garden Nursery in Eugene, OR.

This is just a hint of what happens when plant geeks get together and spend time in the garden.




Matt is always pushing me, I swear!

Next installment is where this pic was taken. Visiting the guys at Dancing Oaks Nursery!!

Garden Shinanigans in Oregon Part 2: Not just Hellebores

After the drool fest and automatic debiting of our bank cards, we strolled the grounds of Ernie and Marietta's garden and, again, were treated to something truly special and awe inspiring.

"Every great garden as great bones" Penelope Hobhouse once said. Their garden is certainly no exception to this statement; it's actually a fine example of it. In the dead of winter, a garden doesn't need to be flat and barren. Having structural elements and shapes, focal points and other objects which direct the eye make for a successful landscape. I included this photo with the guys in the rear so you get a sense of depth and scale. You see a pedestal as a focal point with a fluffy Carex that makes for a simple yet, very effective focal point and on the right, notice the strong, bold anchor that a columnar cypress creates.

I was taught that if you take a black and white photo of a landscape, you can better define these elements and you can really see what holds a landscape together. It's not just the pretty flowers, lush foliage, the color, the texture of it all, it's these bold lines and shapes that make for the foundation of a landscape.

 

Notice how the rare winter sunlight illuminates the form, structure, and then you get a bit of texture enhanced as the contorted branches become more evident. Notice the small mounds made up of conifers and, in the previous photo above, ornamental grasses.  With curving paths and simple rocks staggered about, it makes for a pleasant stroll during a cold, but bright winter's day.

Here are some more captivating scenes from their garden:

Look at this remarkable composition: the height achieved in the background with vertical elements set off by the bright winter foliage of a yellow-needled shore pine Pinus contorta 'Chief Joseph'. And in the foreground, you see their simple rock work with a few mounds of evergreen ornamental grasses and dwarf conifers.  THAT'S ALL YOU NEED and you can have a fabulous garden that looks this great year round!

Even with the remaining foliage of the hardy banana, this photograph illustrates another simple yet effective composition with the variegated yucca flanked by heaths and heathers. In a way, you almost don't notice how ugly the banana is at this time of year.

One of my favorite features of this garden is their spectacular bamboo screen. Meticulously maintained so it doesn't take over all of Eugene, OR, it is a remarkable sight to see. I love the contrast of the aging, multi-stemmed tree against the fine texture and vertical lines of the back-lit bamboo and having the empty containers there

Very important to have  a rest in the garden, both physically with the bench in place anchored by a large container as a "companion", but also a visual rest from everything else that's going on. It may be winter, but there are still a lot of things to see so these wide paths play an important role.

Levels are important especially in these large beds so there's a sense of depth, scale and each plant specimen or planting scheme is

And naturally, the woodlands are inundated with Hellebores!!

Garden Shinanigans in Oregon Part 1: HELLEBORE HOOPLA

A recent trip to Oregon offered many wonderful moments and much needed down time with close friends and colleagues. My buddy, Matt Berberich, a fellow landscape professional up in Port Townsend, met up with me for a plant guy's weekend joined with one of this friends and former classmate at Longwood Gardens, Erik Petersen. Erik is an avid plant collector, specialty nurseryman and recently has taken a position with Oregon Garden, a botanic garden in Silverton, OR.




I sort of spearheaded the trip down to Oregon with the main objective that we pay Ernie and Marietta O'Byrne of Northwest Garden Nursery in Eugene a visit to see (and yes, buy) some of their fabulous Winter Jewels® Hellebores!!! I've blogged about their Hellebores each winter and a visit to their gardens about two years ago. I can't say enough about how incredible their plants are: the well designed and maintained their gardens and what wonderful people that they are.

 
 
Despite the most erratic and sometimes miserable weather we endured during the drive and even upon arriving at the garden, they seemed quite busy with a flurry of Hellebore enthusiast looking over their remarkable nursery stock turning each nodding flower up to observe and admire the exquisite colors, shapes. and forms of what really are the jewels of the winter garden landscape.

That was just a handful of the many wonderful selections they have. Marietta kindly let me through their breeding houses to check out the next generation of Winter Jewels® and boy was I in for a treat. TALK ABOUT BEING LIKE A KID IN A CANDY STORE!!

It was such a treat to be allowed to see these creations. AND EVEN MORE TEMPTING to select a few to take home!! So, Matt and I selected a few: he picked out some for a client, for his own garden and a special selection for his partner, Rebecca. I shopped for myself to have a few of these plants grace Landwave Gardens. This was our opportunity to meet with Ernie and Marietta and just share in the joy and love for plants and gardens. I'm always inspired and end up just feeling good when I visit!

Next on this series, a tour through their amazing gardens!!!
