A magical journey to one of the world's hottest spots of biodiversity
African plants have had a significant impact on Denver Botanic Gardens and regional horticulture. Travel to Africa by over a dozen DBG staff have brought back a wealth of knowledge and germplasmâsome of it new to scienceâthat have provided some of the most popular and successful perennials and groundcovers in our region, such as the many hardy ice plants, African daisies in several genera, Kniphofia, Helichrysum and much more. They could be argued to have truly helped launch the Plant Select program (which continues to introduce new ones). DBG staff maintain research South Africa, working with Katse Botanic Garden in Lesotho under the auspices of that country.
Three of the leading authorities on South African plants are joining for the first South African symposium of its kind in our region: âOut of Africaâ will be out of this world! Be there!
Karel Du Toit
"Richtersveld - The Spectacular Wilderness"
This enchanted, rugged and extremely arid National Park – a World Heritage Site – harbours many endemic succulent plant species, some of which are rarely seen. Karel du Toit, a policeman by night and a passionate naturalist by day, explores the magical landscapes and diverse variety of plants and animals that survive there.Â
Â
Karel has served 37 years as a detective in the South African Police Department, overseeing as Captain the Springbok Stock Theft and Endangered Species Unit in the northern Cape where millions of rare plants as well as animals have been under enormous pressure from poachers. Karel has arrested dozens of poachers and confiscated over a million stolen plants.
Â
He has unparalleled knowledge of the flora and folkways of South Africa. As a well-known and highly respected officer of the law, he commands the respect of landowners who allow him access to some of the most biodiverse land on the continentâaccess few are allowed due to the depredations of poachers. He has been leading tours to these remote places for several decades and has recently retired from police work in order to expand his tour company, Pillansii Tours.
Â
Karel is also an extraordinary photographer.
Â
Those who have traveled with Karel are impressed not only with his extraordinary knowledge of plants, people and places, but by his sensitivity to those he guides. His good humor, sense of fun and attention to detail are second to none. His passion for South Africa is infectious!
Â
He will conduct his first visit to North America this March, headlining a star-studded Study Weekend for the North American Rock Garden Society on the East Bay of California, and then a half day symposium at Denver Botanic Gardens sponsored by the Rocky Mountain Chapter of the North American Rock Garden Society and the Cactus and Succulent Society of America.
Adam Harrower
"The miniature world of the Knersvlakte, South Africa"
Adam Harrower is Senior Botanical Horticulturist; curates the conservatory and xerophytic plant collections at Kirstenbosh National Botanical Gardens. His talk will present a macro view of a miniature world of plants all adapted to living in the harsh arid conditions of life among quartz pebbles. This talk will explore some of the endemic succulents and bulbs that thrive in this environment, including numerous species that are new to science.
Â
Prior to taking on his current challenging job, he was Arborist who oversaw the unique and extensive Kirstenbosch tree collections, and truth be said, his knowledge of herbaceous, shrubbyâall plants of South Africa reallyâis second to none.
Â
In addition to his extensive fieldwork throughout South Africa resulting in the discovery of many taxa new to science, he has rediscovered many long lost species, and documented these not only with scientific specimens, but by professional quality photography, best seen in the gorgeous coffee table book Kirstenbosch: The Most Beautiful Garden in Africa, coauthored with Brian Huntley and published in 2012.
Â
Adam is also an accomplished Bonsai growerâspecializing in South African treesâwhich are wonderfully showcased in the entry courtyard of Kirstenbosch. Adam is no stranger to North America, where he has often come to visit in-laws. This is, however, his first time lecturing here, first at the Study Weekend for the North American Rock Garden Society on the East Bay of California, and then a half day symposium at Denver Botanic Gardens sponsored by the Rocky Mountain Chapter of the North American Rock Garden Society and the Cactus and Succulent Society of America
Steve Brack
Growing up on a small family farm in Wisconsin I became interested in horticulture at a young age, grew plants as a kid to enter in the local county fair. While in college studying physics after seeing some cacti and succulents at a friendâs house on the windowsill, I went to the library to find some books on these strange plants. I started reading these books and found the plants just fascinating. I used interlibrary loan to borrow hard to get books and a big world opened. In some of these books various clubs and Societies were mentioned, so I wrote away to join a few and then found seed lists from the groups.
Â
I started to grow cacti and succulents from seed and acquired a few plants back in 1970. Soon was on the hunt for seed lists, and what was amazed me was to get seeds with a Latin name and the geographic source. Then I read a series of articles in a British journal about the travel adventures of an English tourist that visited New Mexico. At this point I was interested in seed growing and the idea of moving to New Mexico to start a nursery really took hold. I wanted a life working with seeds. My wife accepted this weird idea instead of becoming a physics teacher, and we moved to NM in the spring of 1973. After 3 years of working on the project we started Mesa Garden in 1976.
Â
Since 1973 we have taken many trips to collect seeds to grow stock plants for the nursery, it has been a great life of desert camping, hiking and seeing plants in nature. After 41 years of running the nursery, we sold it to a couple that were employees and are busier than ever in retirement.
Â
Mesa Gardens has unquestionably been the premier source of cactus and succulent seed over the last half centuryâhaving offered more than 10,000 taxa at one point or another. Steve Brack has undertaken over 30 trips to South Africa over the last half centuryâand has unparalleled knowledge of that country. One of his little-known claims to fame was that he was a mentor to Karel Du Toitâlaunching Karel as a field botanist.
