Plants held at Roseland House The History of Lapageria rosea at the University of California Botanical Garden
CHRIS CARMICHAEL and CARLOS RENDON

... we began our collecting under the falls of the Rio Piknaiquen. We gave attention, first, to el copihue but soon found that all the plants in sight were still in bud. This was a disappointment, but a glance at the rest of what was growing in the humid chasm was encouraging.

The heavy mists floating across the downpouring water and over the pools that it formed were continually blown downstream, as well as up the steep chasm walls. In this gentle bath, ferns, mosses, and other lowly , plants luxuriated-----

The University of California Botanical -L Garden has a long history of cultivating Chilean bellflowers (Lapageria rosea). Known to Western science since the early part of the nineteenth century, the name Lapageria is derived from the maiden name (Lapagerie) of Napoleon's Empress Josephine. Revered as the national flower of Chile, the pendulous, waxy flowers possess a distinctive, leathery substance. The three- or four-inch-long, humming bird- pollinated flowers are a bright crimson in the wild form. Many beautiful cultivars have extended the color range and floral structure of this striking plant. Native to the coastal mountains of Chile and to the lower elevations of the Andes, in the southern third of the country where rainfall is relatively reliable throughout the year, it is found in damp forests climbing on the lower branches of the native trees and shrubs. This vining lily relative is now variably assigned to the families Philesiaceae or Smilacaceae, depending upon the authority. Leathery, dark green leaves adorn the vines, which can exceed fifteen feet long in cultivation and may be much larger in the wild.

Lapageria require warm, temperate conditions, and can be grown indoors as a conservatory plant in areas that freeze regularly. However, they will tolerate some freezing, and, indeed, Bay Area plants are reported to have rebounded well from the big freeze of 1972. Given ample summer water and protection from strong sun, this plant can put on a spectacular show of pendulous flowers, reaching a peak from August through December. Coastal California and, in particular, the San Francisco Bay Area, provides probably the best climatic conditions for growing Lapageria in the United States. The moist, coastal influence and moderate temperatures allow gardeners to most nearly approximate the growing conditions of coastal Chile. Lapageria prefer an acidic and highly organic soil that does not compact as it breaks down. Quite amenable to pot culture, these plants require good drainage, whether in a pot or in the ground. Lapageria have been grown in Europe since at least the middle of the nineteenth century, indoors in cool greenhouses and outdoors in hospitable microclimates in the British Isles.

Direct from Chile

Lapageria first appear to have entered the UC Botanical Garden's collection through the efforts of T Harper Goodspeed, a professor of botany who, as curator or director, was deeply involved in the development of the Garden from 1919 to 1957. Goodspeed made six collecting expeditions to the Andes of South America; a seventh was launched under Dr Herbert Baker's directorship. While his primary focus was on members of the genus Nicotiana, he and expedition members collected a range of Andean material including many cacti and succulents still present in the Garden's New World Desert Area and Arid House. A wild accession of Lapageria rosea, collected near Trumao, Chile, and dating to Goodspeed's 1935-1936 expedition, continues to thrive in the South American Area of the Garden.

Subsequent additions of Lapageria to the collection were numerous, and nearly all were cultivate "of" 'Horticultural origin received directly from Chilean sources. Goodspeed, and his colleague, Garden botanist Paul Hutchison, established a lasting relationship with the nursery at El Vergel Farm, a Methodist mission and agricultural school in Angol, Chile. Lapageria cultivation at El Vergel appears to have been conducted by director Dr Dillman Bullock and horticulturist Elbert Reed. Bullock's name appears in the accession records of the Garden as a source of Lapageria plants and seed; he is also cited in Goodspeed's fascinating account of his collecting expeditions, Plant Hunters in the Andes, published by UC Press in 1961. Hutchison accompanied Goodspeed on his fifth expedition to Chile in 1951 and 1952. Garden records indicate that Hutchison obtained a large number of Lapageria cultivars from El Vergel during this expedition. In his book, Goodspeed describes bringing plants back from Chile as expedition members returned to San Francisco on a Grace Line freighter. Plants were grown in soii-filled tubs on the ship's deck, where they were given constant attention. Upon arrival, soil was washed from their roots for agricultural inspection, and the plants were rushed to Berkeley to be properly repotted. He planted them out in the Garden in both the South American Area and in the Asian Area. They particularly prospered in the latter site due to its moist and humid growing conditions under a redwood canopy. Several of these cultivars, including 'Collinge' (syn. 'Dr Bullock') and 'Ligtromu' (syn. 'Whte Cloud') still grow in the Garden. Throughout the 1960s, Hutchison obtained more plants from El Vergel by mail,

Hutchison also grew Lapageria from seed sent to him from Dr Bullock. He selected a seedling of special merit grown from seed obtained by Bullock from a plant of the cultivar 'Ligtromu' at El Vergel. Hutchison named it 'Mission Lace' in 1955; it is probably the first cultivar of L. rosea named in California. It still grows in the Garden and is available in the nursery trade.

Dispersing a Garden Jewel

Over the years, the Garden developed a volunteer corps, which at some point began propagating plants from the collection to be sold in support of the Garden. Lapageria have been a key part of that volunteer propagation program for many years. In 1990, Garden volunteer Sarah Wikander and others began propagating the wild-collected stock as well as the named cultivars and selling them at plant sales. She obtained additional cultivars from local plant- collectors, and interacted extensively with Alek Koomanoff, who, at the time, ran the nursery at Strybing Arboretum and Botanical Gardens (now San Francisco Botanical Garden at Strybing Arboretum). Garden staff member Martin Grantham also supported her efforts and assisted with propagation. Sarah brought back more plants from El Vergel when she visited there in 1992. She also began a breeding program, making crosses and recording the color distribution- of her seedlings. Her work resulted in the widespread distribution of Lapageria to Bay Area gardeners throughout the 1990s, sparking and encouraging interest in this garden-worthy plant.

Garden volunteer Carlos Rendon succeeded Sarah in working with the Lapageria in 2001. He began another propagation program on a larger scale, producing plants from both cuttings and from seeds produced through hand-pollination of the flowers. He set up a catalogue system for tracking seedlings that included information on parentage, general vigor, and floral characteristics. It takes three to five years for Lapageria to flower from seed, so this effort, along with Sarah's previous work, represents a major commitment to the horticultural development of this striking plant. We hope that Carlos's database will assist in defining more effective methodologies for Lapageria culture and propagation, and provide specific information on the outcomes of hybridization. Carlos also made a commitment to search for propagation material of cultivars not already in the Garden's possession. He focused particular energy on obtaining Chilean cultivars, including many that had been lost from the Garden's collection over the years. A number of selections were obtained in 2004 through generous donations from Marin County collector Alejandro Montenegro, who was born in Chile.

Currently, the Garden has approximately two dozen named and unnamed Lapageria cultivars in propagation, making the collection one of the most comprehensive in North America. These include Chilean, British, and American cultivars, though by far the largest number derive from Chilean sources, particularly El Vergel. The flowers of wild-type Lapageria are a deep, rosy red, generally speckled with spots of paler red or even white. White-flowered plants are reported from the wild, and many in Chile have long Sought out additional color variants

Cultivars fall into four main color groups: reds (eg 'Caupolican', 'Beatrix Anderson'), whites (eg 'Ligtromu', 'Toqui'), pinks (eg 'Colibri', 'Qngol'), and picotee or bi colored (eg 'Collinge', 'Relmutral'). Other variations include spotted cultivars, such as the red 'Mission Lace', and a double or semi-double red called 'Quelipichum'. Known in Chile by the common name of copihue, most of the cultivars arising from El Vergel have names derived from the language of the native Chilean Mapuche people. Spanish and English names, often translations, have been applied for many cultivars; for example 'Ligtromu' is also known by the names 'Nube Blanca' and 'White Cloud'. 

NB:-   in 2009 Carlos stepped down from his roll as volunteer propagator at Berkeley Botanic but before doing so he arranged that most of the plants held in their collection were made available to us here at Roseland and of course the large quantity of plants he produced will mean that in California at least most varieties are not down to just one or two individual plants as was previously the case.
