See you at Joan Sanders the share table. June Voorsanger, Chair of Share May Program Andrea Wulf Returns to Garden Club Don't miss Andrea Wulf, author of The Invention of Nature, Alexander von Humboldt's New World, at our May 2nd meeting. Wulf addressed the Garden Club in April of 2016, speaking to us about her research for Founding Gardeners and the horticultural passion of the men who shaped our country. Born in 1769 in Germany, Alexander von Humboldt seems to be a man ahead of his time. He precedes both Charles Darwin and John Muir, men we often look to for our ideas about nature. But, as Wulf tells us on page 8 of her book: "Humboldt gave us our concept of nature itself. The irony is that Humboldt's views have become so self-evident that we have largely forgotten the man behind them. But there exists a direct line of connection through his ideas, and through the many people whom he inspired. Like a rope, Humboldt's concept of nature connects us to him." Throughout his life, Humboldt went to great lengths to explore faraway places and investigate environments that were dangerous. These are brought to life in Wulf's book which provides an opportunity to learn about a man who was a vital part of science in general and environment issues in particular. Sue Krumbien, Chairwoman of the Day Great Plant Giveaway What? Our 6th Great Plant Giveaway! OK, can you believe it? Our sixth Great Plant Giveaway is just around the corner. This is getting to be a Garden Club tradition -- a loved and anticipated one at that! It's been a year since the last GPG (as it's now affectionately known), so in case you are rusty on the rules, here are some reminders: 1) When you come to the May 2 meeting, bring your extra plants, seedlings, cuttings, divisions, and seed packets in a box labelled with your name and the names of your plants. Don't forget your name -- we want to know who brought these green babies. 2) It really helps to label plants with their proper Latin name and cultivar, such as Sedum 'Angelina' or Pelargonium sidiodes. 3) You can also bring empty 4" pots and gallon cans. We'll have a table where you can leave them. 4) Don't forget a box or big bag to transport your new treasures. 5) Leave your donations on the tables in the church courtyard before the Member meeting. 6) The Giveaway begins 10 minutes after the meeting is adjourned. Please come and stand by your plants for awhile, as half the fun is in the sharing and shop-talk. 7) While you're browsing, you can visit the "Ask Me" table for help. There are helpers to talk to, books to consult, and plant labels if you need them. 8) At the end, please take away any of your plants that haven't been taken. Above all - Enjoy! Carol Malcolm and the Great Plant Giveaway Gang: Robin Allen, Connie Cavanaugh, Eleanor Laney, Vicki Sullivan, Katsy Swan and Gwen Whittier Field Trip Thursday, May 4th. Late morning, followed by lunch. A repeat visit to DERK HUNTER'S magnificent WOODSIDE GARDENS (last visit sold out quickly). Drive yourself or carpool. Cost: $15.00 (lunch by Douce France) Limit: 25 members. If you went on a previous visit and are interested in returning, we'll put you on wait list.

Please also let us know your birth month, so we can honor you in our newsletter. It is important to all of us that you fill out the areas in which you will volunteer to be part of a committee, or even its chair, and list your special skills or knowledge. Although the board positions are filled for this year, the nominating committee will keep a list for next year. Mindy Kirkpatrick will give the list of members' choices to each committee chair who will set up the committees and contact you. It is always fun to work with your Garden Club friends. I will have extra Membership Renewal forms at the May meeting for those who wrote a check, but didn't fill out the form. Sue Beebe, Membership Chair Support our Local Birds Every patch of native greenery, however small, is a tangible contribution to healthy habitat for birds. Download the Audubon "Plants for Birds" website to identify and acquire the right plants for your location and the birds you love (such as this Song Sparrow). https://www.audubon.org/native-plants Conservation Western Monarch Milkweed Mapper In February 2017, the Xerces Society, collaborating with the Idaho Department of Fish and Game, and the Washington Department of Fish and Wildlife, with funding from a U.S. Fish and Wildlife Service State Wildlife Grant and the National Fish and Wildlife Foundation, launched the "Western Monarch Milkweed Mapper." Loss of milkweed is the most significant factor contributing to monarch declines in the eastern United States, yet little is known about the reasons for decline west of the Rockies. To help fill this information gap, the Xerces Society's Western Monarch Milkweed Mapper, a new citizen science program and data sharing platform, will gather milkweed and monarch observations across the butterfly's breeding and migratory range West of the Rocky mountains. Since our GCPA Monarch Migration Revival has already planted over 500 gardens with milkweed in our SF Peninsula, it is important we register our extensive project on the Xerces western milkweed map! Here's how you can help this happen: 1) Visit the WMMM website https://www.monarchmilkweedmapper.org to download the registration yourself and send in your milkweed photo OR (and much easier) 2) Let Eleanor do the work! Take a photo of your of your milkweed plant with its new spring leaves and email it to me ([email protected]) along with the address where it is planted. Please take two minutes to send me your milkweed photograph today! Many thanks, Eleanor Laney, Conservation Chairman Horticulture May in Your Garden Spring weather came early with lots of rain. My spring bulbs are long-gone! I take care of daffodil bulbs so they will multiply for next year. Cut off the fading flower, but the leaves should stay until they turn brown so the plant can put its energy into the bulb. This May it is important to put mulch around shrubs and trees to protect them from the wind and early summer heat. Put down compost, then a thick layer of mini-mulch. Leave an inch of space around the trunk. Garden experts agree that mulching is the most protective method for controlling seasonal heat and improving the soil. Mulching reduces the time spent weeding and cultivating, keeps plants cool, makes a bumpy surface that snails don't like, and encourages worms and other organisms that create healthy soil. Acid loving plants thrive in an acid environment such as pine needles, oak leaves, or peat moss as a mulch. I get a half yard of mini-mulch once a year delivered by Ciardella's. Summer Winds has 2 cu.ft. bags of mini-mulch. Avoid regular sized chips. They don't break down well. May is dahlia planting time. Find a sunny spot, dig a hole five inches deep, add a handful of bone meal covered by a small handful of soil. Lay the tuber on its side in the hole; put a stake at one end of the tuber; and close up the hole. Don't forget snail and earwig bait, or cover the first sprout with a quart-sized plastic pot with its bottom removed, shoving the empty container firmly into the soil.

  • 2019 Is the Year of the Dahlia
    2019 is the Year of the Dahlia Did you know that the dahlia is the national flower of Mexico? The native dahlias found in the mountains of Mexico and Guatemala are the genetic source for the modern hybrid dahlias we grow today. There are many species of dahlia in a range of colors and forms with hybrids commonly grown as garden plants. The flower varies in size and form. Each flower can be small or large, ranging from 2” in diameter to up to 15 inches. The largest flower form is informally known as a “dinner plate” dahlia. Getting Dahlias There are several ways to enjoy your first dahlia. Most major garden centers, home improvement stores and mail order sources sell dahlia tubers (a thick, underground stem or rhizome) as well as blooming potted plants. A tuber looks like a sweet potato that grows under the soil surface and sends up strong stems. Additionally, almost every dahlia society has tuber and plant sales and they welcome guests to those events. When to Plant Your tubers can go directly into the ground in the spring when the ground is warm and there is little chance of frost. One good guideline is to plant at the same time as you would a tomato. If you want blooms as early as possible, you can start the tubers indoors in good light about a month before planting time. By starting early you could have a small plant ready to transplant at planting time. How to Plant Plant the tuber according to the package directions with the “eye” on the tuber facing up.

  • Of Dahlia Myths.Pub
    Cavanilles’ detailed illustrations established the dahlia in the botanical taxonomy In 1796, the third volume of “Icones” introduced two more dahlia species, named D. coccinea and D. rosea. They also were initially thought to be sunflowers and had been brought to Spain as part of the Alejandro Malaspina/Luis Neé expedition. More than 600 drawings brought the plant collection to light. Cavanilles, whose extensive correspondence included many of Europe’s leading botanists, began to develop a following far greater than his title of “sacerdote” (priest, in French Abbé) ever would have offered. The A. J. Cavanilles archives of the present‐day Royal Botanical Garden hold the botanist’s sizable oeu‐ vre, along with moren tha 1,300 letters, many dissertations, studies, and drawings. In time, Cavanilles achieved another goal: in 1801, he was finally appointed professor and director of the garden. Regrettably, he died in Madrid on May 10, 1804. The Cavanillesia, a tree from Central America, was later named for this famousMaterial Spanish scientist. ANDERS DAHL The lives of Dahl and his Spanish ‘godfather’ could not have been any more different. Born March 17,1751, in Varnhem town (Västergötland), this Swedish botanist struggled with health and financial hardship throughout his short life. While attending school in Skara, he and several teenage friends with scientific bent founded the “Swedish Topographic Society of Skara” and sought to catalogue the natural world of their community. With his preacher father’s support, the young Dahl enrolled on April 3, 1770, at Uppsala University in medicine, and he soon became one of Carl Linnaeus’ students.

  • Zinnia's Are a Beautiful Annual Flower, Very Easy to Grow from Seed And
    Bell County Master Gardeners Tip of the Week By Jann Dworksky Zinnias—A Personal Favorite Zinnias are a beautiful annual flower, very easy to grow from seed and with an interesting history. They are native to Mexico where they were erroneously named “mal de ojos,” which literally means sickness of the eyes. This certainly makes me wonder what some other flowers looked like if zinnias looked sick! Zinnias were given the first written description in the 18th century by Dr. Johann Gottfried Zinn, a German medical professor. He also studied the eye and because of his work, a part of the eye is called the zonule of Zinn, or Zinn’s membrane. Zinnias are personally my favorite flower and I have about 40 square feet planted in zinnias. They attract butterflies and hummingbirds and some of my best photographs of zinnias include these lovely insects. Zinnias require regular watering, but because of their striking colors and tolerance of the extreme Texas heat they will give you a superb display, even in a small space. Zinnias should be planted outdoors in an area receiving 8 hours of direct sun. Dappled shade will produce weak, spindly plants that will do poorly. Many of the packages of zinnias say they may be started indoors 6 weeks before the last frost, but they are a heat loving plant and do poorly until the ground is warm. A two foot square planted in zinnias will add an eye catching boost of color to any flower or shrub bed. Water zinnias early in the day and avoid getting the leaves wet as they can develop a powdery mildew.

  • Of Dahlia Myths.Pub
    A year later the Humboldt seeds were distributed in France and sent to Dresden and Berlin. These clearly came from a dif‐ ferent genetic background than the three varieties that Cavanilles had classified. Quickly the color range expanded to dark red, yellow and even white flowers; hybridization efforts also yielded semi ‐double forms. As the distribution of dahlias throughout Europe intensified, new varieties were introduced. In 1809, shortly before his death, Willdenow returned to the topic in his well‐known Hortus Berolinensis VIII. Willdenow analyzed the three Spanish dahlias and determined that D. rosea and D. pinnata (he called it purpurea) were essentially similar. Alluding to their vexing flowering habits, he combined these subspecies under the descriptor Georgina variabilis. Yet G. coccinea was found to be distinct, and so retained its appellation. He then added the new varieties G. lilacina and pallida. The former may have been a variant of rosea, while the latter points to the emergence of whitish flower forms. De Candolle added to the name confusion in 1810: Although by then well aware that Willdenow’s assumption was in error, his Note sur les Georgina (published in the Annals of the French Natural History Museum) affirms the accuracy of the Ger‐ man botanist’s observation. Nevertheless, the editors of the journal objected: In a side note they referred to the general acceptance in France and elsewhere of ‘dahlia’ as the proper name. No matter ‐ for at least the next hundred years, most Central and all Eastern Europeans continued to use georgina. This disparity led some to conclude that georginas were only distantly related to dahlias.

Nowadays, Dahlia was widely used even in economical purpose: in landscaping, in floristry as a cut flower, for the pharmaceutical industry, cosmetic, food and as raw material for the extraction of dyes. Both the tuberous roots and the flowers of this ornamental and medicinal plant are used for therapeutic purposes. The biochemical composition that is very varied containing: flavonoids, carbohydrates (inulin), polysaccharides but also other uses, it is desirable to promote valuable cultivars for use in breeding works for the production of descendants that combine polygene for a high decorative value and an increased inulin content. Keywords: Dahlia, therapeutic purposes, inulin, polygene, tuberous roots Introduction Dahlia plant culture spreads from Spain to different European countries (Tarhon, 1993) and it was brought to Madrid in 1790 (Cristea, 2014). Dahlia is a perennial semi-rustic plant that gives the best results in hill and submontane areas where it blooms from July to late autumn (Băla, 2007). Dahlia represents the richest specie as a garden and a balcony flower. The genus includes about 30 perennial species with tuberous roots belonging to the Asteraceae family (Lord, 2003).

  • Master Gardener Corner: Zinnias Originally Published: Week of August 30, 2016
    This article is part of a weekly series published in the Batavia Daily News by Jan Beglinger, Agriculture Outreach Coordinator for CCE of Genesee County. Master Gardener Corner: Zinnias Originally Published: Week of August 30, 2016 Zinnias have been a popular garden annual for many years. Not only do they come in a wide range of flower colors and shapes but they are easy to grow from seed. Native to the southwest US, Mexico and Central America, they can tolerate hot summer temperatures. They were named for the 18th century German botanist, Johann Gottfried Zinn, who wrote the first scientific description of the flower. The wild zinnia that Zinn found in the Mexican desert was a small, weedy plant with a purplish-red, daisy-like flower and a protruding cone. Spanish colonists called them “mal de ojos,” (evil eye). Seeds were sent to Europe and plant breeders started playing with them. The gardening world didn’t become interested in zinnias until 1920 when Bodger Seeds Ltd. introduced ‘Giant Dahlia’ and ‘California Giant.’ Still available today, they come in a variety of colors and the blooms are large and flat- petaled. Zinnias come in such a wide variety of colors (except blue, black and brown), that you can choose from bright, brilliant reds, oranges, yellows and pinks to soft, creamy pastels, white and even green flowers. There are also bi-colors, striped and speckled varieties to choose from. Zinnias bloom in many shapes and sizes. Blooms can range from one-half to six inches wide. They may be single, semi-double, or double.
