Be sure to look for pieces turned from Arboretum wood as well. \n\n\n\nExperience in-depth demonstrations on the lathe in the Hunnewell Lecture Hall at 11:00am\, 1:00pm\, and 3:00pm on Saturday and Sunday\, and throughout both days on the Hunnewell lawn. \n\n\n\nRegistration is not required for this event but helps us to plan. \n\n\n\nAccessibility: The lecture hall is wheelchair accessible. \n\n\n\nAudience: This program is appropriate for all ages. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:Seed Propagation at the Arboretum
DESCRIPTION:Rescheduled from October 5 due to construction. \n\n\n\nThis is a members-only program. Not a member? Click here to join! \n\n\n\nMany of us assume that growing plants from seed is as simple as opening a seed packet and sticking them in the dirt\, but many of the trees and shrubs in the Arboretum’s collections require a complicated process of stratification\, maceration\, and dormancy breaking before they will sprout. Join Arboretum Propagator Sarah Shank for a workshop on growing these plants from seed and get a chance to try your own hand at germinating seed from Arboretum trees and shrubs. \n\n\n\nThe class will begin with a presentation on the biology of seed dormancy and germination\, and then we will move into the hands-on portion where participants get experience preparing seeds from fruits and dry capsules\, scarifying seeds with different dormancy types\, and finally sowing some seeds to take home. We will round off the experience with a brief tour of the seed treatment facilities and seedling greenhouse. \n\n\n\nAll participants will go home with a tray of seeds they planted. We will be focusing on plants that can easily be grown in a front or backyard\, so you don’t need to worry about finding a place for a 100-foot-tall tree! \n\n\n\nAccessibility: This program takes place indoors in the wheelchair-accessible DGH classroom and outdoors on mowed grass. \n\n\n\nAudience: This members-only program is geared towards adults. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:The Cosmic Tree: A Universal Symbol of Life: Ginkgoes & Conifers
DESCRIPTION:Cosmologies are ways of understanding the nature of the universe\, of experiencing the world in all its variations including the visible and the invisible. Over millennia trees have served as the mythological archetype of the world’s axis (axis mundi)\, the pole through the earth’s center which connects the worlds above and below. Within a cosmic-magical model of the world  (imago mundi)\, trees also evolved in various cultures to possess innate spiritual powers or as conduits for communication with the holy or sacred. \n\n\n\nDocent Katrina Scott will lead this interactive tour with stops for moments to reflect on specific trees and the stories associated with them. Were they revered or feared?  A home for deities or tricksters?  We will begin at the Walter Street Gate to visit the oldest ginkgoes at the Arboretum\, then head up the Conifer Path and diverge to walk\, rest\, and reflect among various conifers\, eventually ending by the yews near Bussey Brook and Hemlock Hill Road.  \n\n\n\nAccessibility: This walk will include woodchip and gravel paths. Please wear long pants and closed toe shoes and bring a cloth/towel/mat for sitting/lying down. \n\n\n\nAudience: This program is geared towards adults. \n\n\n\nWeather Policy: Tours may be canceled in cases of the following weather conditions: severe wind\, snow\, ice\, thunder or lightning events; temperatures over 90 degrees; and temperatures below 20 degrees or due to other weather events at the discretion of Arboretum staff.

SUMMARY:Research Spotlight: Climate Change and Root Exudates

SUMMARY:Tree Mob: The Oldest Tree in the Arboretum
DESCRIPTION:This is a members-only program. Not a member? Click here to join. \n\n\n\nLong before this landscape had ever dreamed of becoming an Arboretum\, a white oak grew quietly on the slopes of Peters Hill. Years passed and Arboretum staff eventually incorporated this very old tree into our official collections\, making it possibly the oldest accessioned tree in the landscape. Join Assistant Curator Miles Sax for a Tree Mob to learn about this oak\, what the landscape looked like before it was an Arboretum\, the science of tree age\, and how the Arboretum manages those trees that we never chose to plant but which are a treasured part of our collections nonetheless. \n\n\n\nAccessibility: This program involves walking over mulch and paved paths and up a moderate hill. \n\n\n\nAudience: This program is geared towards adults. \n\n\n\nInclement weather policy: Participants will be notified via email at least one day in advance if a program needs to be cancelled due to inclement weather\, and will be notified by phone if a program must be cancelled with less one day’s notice. Click here to view our full inclement weather policy. If you have questions about the status of a program\, please email publicprograms@arnarb.harvard.edu (inbox monitored on weekdays) or call the Visitor Center desk between 10:00am and 4:00pm at (617) 384-5209.

SUMMARY:Built to Withstand: How Plants Resist Wind and Weight
DESCRIPTION:How do trees\, bamboo\, marsh grass stems and cattail leaves stand so tall?

SUMMARY:Reading the Forested Landscape
DESCRIPTION:The forest is a constantly changing landscape where tree species dominate and then fade away\, to be replaced by other species in the ongoing process of succession.

SUMMARY:The Founder of Modern Botany in China: Celebrating the Life and Legacy of Hu Hsen-Hsu (aka H.H. Hu\, Hu Xiansu)
DESCRIPTION:Join us to celebrate the life\, groundbreaking scientific work\, and legacy of Hu Hsen-Hsu (aka H.H. Hu\, Hu Xiansu) on the 100th anniversary of his doctoral degree from Harvard. After conducting his doctoral work at the Arnold Arboretum under the direction of Professor John Jack\, Hu returned to China where he co-founded or led several of the country’s most important botanical institutions\, such as the Fan Memorial Institute of Biology\, the Botanical Society of China\, and the Lushan Botanical Garden. In 1948\, Hu and his colleague Zheng Wanjun (Cheng Wan Chun) announced to the world the identification of the “living fossil” Metasequoia glyptostroboides or dawn redwood\, a species previously considered extinct. The Metasequoia seeds that Hu sent to the Arnold Arboretum that same year are now majestic trees that grace the Arboretum and stand as its logo – an enduring symbol of natural beauty\, scientific discovery\, and international cooperation.    \n\n\n\nThis online event will feature Arnold Arboretum Director William (Ned) Friedman\, Chief Scientist at the China National Botanical Garden (North Garden) Ma Jinshuang\, Professor of Sociology at Beijing Normal University Hu Xiaojiang (granddaughter of Hu Hsen-Hsu)\, and other speakers discussing Hu’s life and influence. Free and open to the public. Registration required.    \n\n\n\nDue to this program’s international audience\, the webinar will begin at 7:00am Eastern Standard Time and 20:00-21:30 China Standard Time. We will provide translation from English to Chinese and Chinese to English.  \n\n\n\nYou will receive Zoom login information by email before the program.  \n\n\n\n— \n\n\n\n中国现代植物学奠基人：胡先骕的生平与遗产纪念活动 \n\n\n\n值此胡先骕 (Hu Hsen-Hsu) 获哈佛大学博士学位 100 周年之际，我们诚邀您共同缅怀他的生平、开创性科研工作及其不朽遗产。胡先骕在阿诺德植物园师从 John Jack 教授完成博士研究后返回中国，参与创办并领导了中国多个重要植物学机构，包括中国植物学会和庐山植物园。1948 年，胡先骕与同事郑万钧 (Cheng Wan Chun) 向世界宣布了“活化石”水杉 (Metasequoia glyptostroboides) ——此前被认为已灭绝——的鉴定成果。同年，胡先骕寄往阿诺德植物园的水杉种子如今已长成参天大树，装点着植物园并成为其标志——象征着自然之美、科学探索与国际合作的永恒符号。 \n\n\n\n本次线上活动将邀请阿诺德植物园园长 William (Ned) Friedman、中国国家植物园（北园）首席科学家马金双、北京师范大学社会学教授胡晓江（胡先骕孙女）等嘉宾，共话胡先骕的生平与影响。活动免费向公众开放。需提前注册。 \n\n\n\n考虑到国际观众参与，本次线上研讨会将于美国东部时间上午 7:00/北京时间晚上 8:00 开始。 \n\n\n\n活动开始前，您将通过邮件收到 Zoom 登录信息。
