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。

SUMMARY:Growing Plants from Hardwood Cuttings
DESCRIPTION:This is a members-only program. Not a member? Click here to join. \n\n\n\nHardwood cuttings are one of the many techniques the Arboretum uses to propagate its plants: propagators take cuttings from the mature stems of woody plants\, carefully trim and coat the ends in rooting hormone\, then plant them in specially designed growing media. Join Arboretum Propagator Sarah Shank for a hands-on workshop to learn this specialized form of propagation: the class will begin with a presentation on the biology of hardwood cuttings\, then head outside to collect our own cuttings from nearby woody plants\, and finally return inside to prepare and root the cuttings in growing media. Participants will bring home a small tray of cuttings to grow into their own small trees and shrubs. \n\n\n\nThis program takes place in the Dana Greenhouse Classroom at 1050 Centre Street. Participants are welcome to park in the greenhouse parking lot for this class. \n\n\n\n*This is a small-capacity class: please only register if you are sure you can attend\, and cancel your registration if your plans change. \n\n\n\nAccessibility: This program will take place on paved paths and in the wheelchair-accessible Dana Greenhouse classroom. There will be a minimal amount of walking involved. \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:Olmsted and the Arnold Arboretum
DESCRIPTION:Frederick Law Olmsted\, considered the father of landscape architecture\, designed some 500 public spaces in North America. The Arnold Arboretum is the only arboretum he designed\, a National Historic Landmark\, and a model for others around the world. Docent Bill Beizer\, will identify the elements of the Arboretum that best reflect Olmsted’s philosophy and approach to landscape design.

SUMMARY:The Cosmic Tree: A Universal Symbol of Life: Ginkgoes and 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.  Please wear long pants and closed toe shoes and bring a cloth/towel/mat for sitting/lying down.
