Herb Faire: New Heirloom Offerings

by Joanne Ranck-Dirks

Some of the tomato crop from 2016
Every year, we conduct a few tomato trials of heirloom varieties that are new to us.  Our volunteers evaluate the tomatoes and if the tomato doesn't get a strong "yes" vote, we don't grow it again.  The winner from last year's trials is the Black Cherry tomato.  It is a plump and juicy heirloom cherry tomato with a dark purple color.  As a snacking tomato it is a nice mouthful; it looks great in salads and it is also a prolific producer.  Look for it this year in the Heirloom Seed Project's tent at the faire.

Usually when we think of heirloom vegetables we think of tomatoes, but we also have other interesting and delicious heirloom vegetables.  The HSP will sell individual pots of Lemon and White cucumbers as ell as Patty Pan squash.  These have been known and grown in this area for more than 100 years.  Seeds for these will also be available in the Museum Store during the Herb & Garden Faire.  Because bean planting season comes just after the Herb & Garden Faire, folks may want to purchase beans seeds to plant.  Ornamental beans, such as Scarlet Runner beans and Hyacinth beans, can be purchased in the Landis Valley Museum Store.  Two new varieties of pole beans to try this year are Cardinal pole beans and Green Star pole beans.

Tomatoes are very popular but, because every garden is unique, we encourage you to try new plants in your own space this year.  Your perfect tomato may turn out to be a bean or a cucumber.  Both are great in salads, too.

The Case for Remaining Unattainable: The Blue Rose

by Shayla Carey

I hope you all had a wonderful Valentines Day yesterday—full of requited love and romantic times.  Today, though, I’d like to focus on love unattainable, as symbolized by the blue rose.  Like the black rose, this color is not produced in its purest form by nature in roses.  Florists have their methods of turning white petals to bright or deep blue (example, at left), but gardeners and poets must still pine for happy blooms the color of the sky they smile under.  Rudyard Kipling evoked the blue rose when he wrote a short piece that serves as a warning to suitors with high maintenance sweethearts:

Blue Roses by Rudyard Kipling
Roses red and roses white
Plucked I for my love’s delight.
She would none of all my posies
Bade me gather her blue roses.

Half the world I wandered through
Seeking where such flowers grew.
Half the world unto my quest
Answered me with laugh and jest.

Home I came at wintertide
But my silly love had died.
Seeking with her latest breath
Roses from the arms of Death.

It may be beyond the grave
She shall find what she would have.
Mine was but an idle quest—
Roses white and red are best!

According to Landis Valley’s resident garden historian, Dr. Irwin Richman, for centuries, gardeners used hybridization to tease hints of blue out of red petals.  It didn’t matter if the parents were white, red, or in between, but, because of the more complex chemistry in red petals, they were used more often.  Having said all of that, though, their results were mixed.  “Their results were incredibly subjective,” he says.  “A violet to one skeptical gardener is the elusive prized blue to another.”  He points to a listing in the Heller Rose Company of Indiana catalog from 1916:  “The Wonderful Blue Rose – Violet Blue.”  The description is not a flattering one—especially for a cultivar that the growers are trying to sell—but their honesty proves valuable to posterity.  It is a follows:

“This is the famous ‘Blue Rose’ which is a remarkable variety and endorsed by every leading Rose authority here and in Europe, but in our estimation it has not come up to the recommendation of its introducers.  We have seen it bearing flowers that were very blue and very beautiful, and we have seen it again in other soil bearing flowers which were more of a lavender than a blue, so we think it is largely a question of the soil it is grown in as to whether it develops the color claimed for it by its introducers—cornflower blue.  It is of the Rambler type, a beautiful grower, and even if it never bore a flower it is worth a place in the garden because of its rampant growth and beautiful foliage.  The flowers are produced in great clusters, are semi-double, of medium size, and as a rule are a delicate beautiful blue, but we do not guarantee the color.  It is hardy everywhere; a grand grower; a marvelous bloomer and is one of the most popular Roses in our entire collection.”

This variety is still around today and is known as “Veilchenblau,” which is German for violet blue.  According to the Missouri Botanical Garden’s website, this nearly-thornless hybrid multiflora rose was bred by J. C. Schmidt in 1909 from ‘Crimson Pirate’ and ‘Souvenir de Brod.’  It does best in full sun, but will tolerate partial shade, and can ramble to 10’-15’.  It is hardy to zone 4 and likes a slightly acid, well-drained, loam soil.  It will bloom in late spring, but won’t re-bloom, and the flowers start off as deep magenta, then can fade to a gray-lilac color.

It is interesting that the description above mentions soil.  Some flowers, such as hydrangeas, will turn blue in acid soil.  According to the article, “The Color Conundrum,” by Dr. Linda Chalker-Scott, in the Spring, 2009 issue of Master Gardener magazine, the red and blue hydrangeas have pigments called anthocyanins in the vacuoles of their petals.  Vacuoles are balloon-like cells filled with organic acids and dissolved salts, minerals, and other chemicals.  Sometimes, these pigments can be manipulated by adjusting the soil acidity, which effects the availability of aluminum to the plant (if there is aluminum in the soil—many soil-less mixes have none).  There are many other factors involved, but many blue flowers produce the anthocyanin delphinidin, and the blue hydrangea—for example—requires this pigment, plus a co-pigment, and aluminum to turn a beautiful shade of blue.  Without all three of these, it will revert to pink.  It’s very complex.

Roses, however, do not produce delphinidin naturally, which means that the best that breeders can do is get the faded blue-ish violet colors of cultivars such as “Veilchenblau.”  Scientists at a Japanese company called Suntory have recently genetically engineered a blue rose called “Applause.”  It is touted as the first true blue rose and, thanks to a delphinidin-producing gene inserted from a pansy into “Applause’s” parent, “Cardinal de Richelieu,” it does, indeed produce the blue pigment, though not to the same extent as that of other coveted blue flowers, such as the blue poppy (Mecanopsis grandis, see image below).  "If your soul truly aches for the ultimate blue flower, find the rare and elusive Tibetan blue poppy, Mecanopsis.  Just don't expect to find it at a florist near you," Richman says.

Comparing the two flowers, it is obvious that nature figured out long ago how much delphinidin to pack into vacuoles to produce blue and “Applause” falls a bit short.  The company does cite shortcomings with “Applause” and continues its quest for a more pure blue rose, honing nutrient and aluminum absorption, as well as zeroing in on flavones (a yellow-producing co-pigment) found in other pure blue flowers such as Mecanopsis.  Richman also points out that the real money for Suntory is not in the roses, but in the genes and processes used to engineer the blue rose, as they have patented these from the start to limit competition.

Is this really the blue rose that Kipling sought or is this cheating?  Would his sweetheart have been satisfied with a rose that, according to Wired magazine (“World’s First Blue Rose Soon Available in US," by Danielle Venton, 09/14/11), sold for 10 times as much as other roses when it was introduced or was she just after the unattainable?  Shooting for the moon and landing among the stars is more than just a saying by Norman Vincent Peale; it accurately describes the challenge of trying to obtain the unattainable blue rose and creating something almost as great—the “Vielchenblau” rose, for example.  Suntory used sheer will and billions of yen to engineer a blue rose but, in the process, it may have ruined the romanticism behind the quest for the unattainable by taking away one of its most prominent symbols.  Maybe it’s good that the company holds patents on its rose.  It makes it unattainable to most of us and, in the meantime, gives us back the challenge of accepting, and loving, the roses of red and white we already have.

The blue rose, and its equally elusive black counterpart, will be featured in Richman's book on roses and ray flowers, co-authored with Michael Emery, due out in 2018.

Luck to You in the New Year (with Pork & Sauerkraut)

Blog Post by Shayla Carey

Luck, be it good or bad, is a useful psychological impetus in our daily lives.  Never mind that walking under a ladder is unsafe:  it’s unlucky and so we go around it.  For that reason, we probably save ourselves a lot of hurt from falling objects and/or people.  Traditions abound surrounding luck symbols and, without them, I would have had no reason to try pork and sauerkraut—a savory and salty meal best enjoyed mixed with mashed potatoes (in my humble opinion) and accompanied by cold mulled cider.

2016 Harvest Days
Because my Southern Pennsylvania-bred husband wants to ensure our family’s good fortune every year, we feast upon pork and sauerkraut every New Year’s Day.  It’s a Pennsylvania German tradition that dates back centuries1 and, if my husband has anything to do with it, will last for many more years.  The pig as an ancient symbol of luck and was a farm animal in Europe for thousands of years2.  It roots forward, grows fast, and to possess many meant the farmer was prosperous and would eat for a long time to come3 4.  It was also a symbol of fertility and was associated with the Welsh goddess Ceridwen5 and the Gaulish god Moccus (“pig” is “muc” in Irish, “mochyn” in Welsh, and “moch” in modern Gaulish).  To eat it was to subscribe to the folk notion of “like produces like”1 and other cultures eat it on New Years’ Day too.  The South eats ham, fatback, and hog’s jowl; Italy makes their pork into sausage, and people in the Philippines, Cuba, Spain, Portuga, Hungary, and Austria eat a suckling pig roasted whole.6 7

I, for one, am more of a fan of the luck applied to cabbage, as I could use a little more green in my pocket.  Who doesn’t?  According to German, Irish, and Pennsylvania German lore, cabbage is a symbol of money and consuming it will help you increase your fortune.  This is mainly because of its green color and tendency to resemble folded money when cooked.  For this reason, it shares its lucky distinction with collard greens, kale and chard in the South, and kale in Denmark.  The Croats and Slovaks enjoy their cabbage surrounding meat.8  The Pennsylvania Germans ferment it for weeks in a salt brine before eating it, keeping the nutrition in and imparting it with its distinctive salty tang.  Irish Americans enjoy cabbage at other times of the year, too, and, coupled with corned beef, makes for a simple, nutritious, and satisfying meal. 9 My family also likes to cook cut up cabbage leaves in the same pot as egg noodles.  They are a great vehicle for butter and parmesan cheese and the dish is a really easy side dish for the winter months, as both noodles and cabbage take the same amount of time to cook.

With pork and cabbage meaning so much to so many cultures, I have to admit that my husband’s family may be on to something.  I certainly do feel lucky to be alive, whole, comfortable, and surrounded by family for the coming year.  In the spirit of wishing you luck in the new year, I leave you with a recipe gleaned from the Landis Valley Cookbook, available at the Landis Valley Museum Store.

Pork and Sauerkraut
3- or 4-pound pork roast
2 baking apples
2 quarts sauerkraut
¼ cup brown sugar (more or less, depending on the tarness of the sauerkraut)
Salt and pepper

Put pork into a large roasting pan, fat side up.  Sear all sides of the meat on top of the stove.  Arrange the sauerkraut on top and around the pork.  Thinly slice the apples and mix with the sauerkraut.  Add brown sugar and stir it well into the sauerkraut.  Add enough water to nearly cover the sauerkraut.  Bake at 450 degrees for 15 minutes.  Reduce the heat to 375 degrees and bake until the meat comes off the bones when stuck with a fork.  Serve with mashed potates.  Julia Lewis, c. 1930
