Adenium swazicum Stapf Adenium swazicum occurs in Eswatini (formerly Swaziland) and adjacent parts of South Africa. The stems tend to be weak and decumbent, and the caudex (actually swollen roots) tends to be underground. Plants flower in late summer and fall (some clones flower most of the year). The best distinguishing character is the petals of solid color (no fading toward the throat), which is darker in color and lacks nectar guides. In addition, the anther appendages are very short and hidden within the tube. A. boehmianum is the only other species that shares these floral traits. The 2 species are distinguished by growth form: swazicum is a lax shrub while boehmianum is erect and usually arborescent. White flowers occur in cultivation. A. swazicum 'Perpetual Pink '. This clone is a more sturdy plant than is typical of the species, and it flowers year-round. Flower of A. swazicum 'Perpetual Pink'. A. swazicum flower. A. swazicum 'Boyce Thompson ' . This clone has the typical weak stems of the species, but it blooms 9 months a year with very dark purple flowers. A. swazicum 'Boyce Thompson ' . A. swazicum double flower. It does not appear to be in circulation. Photo: John Lucas Adenium swazicum in the Wild Adenium swazicum in the Hlane Game Reserve, northeastern Eswatini. The plants are often short because they are periodically burned to the ground in brush fires and grazed by impala. Photos: James Culverwell Note: A. swazicum is becoming rare and difficult to find because it is extensively collected by local people for medicine. I would love to post more photos of this plant in the wild. If you have any, please contribute photos and a description using this form . Due credit will be given. Back to Top Footnotes

Superior Cultivars of Adenium crispum x "obesum" Back to Gallery See the hybrid page for the general characteristics of this hybrid group. Adenium crispum x "obesum" hybrids are renowned primarily by their boldly blotched and striped flowers. There are already thousands of named cultivars in this group, and adenium breeders are creating many more every year. For this reason, most of the cultivars that are more than a few years old are already obsolete and probably no longer on the market. Keeping up is impossible. This is generally true of adeniums, but especially so for crispum-obesum hybrids. The goal of this gallery is to present a selection of the vast variety of flowers, many of which arrived and vanished without ever being given names. 'City' 'Harry Potter' 'OMG!' 'Strawberry Sundae' 'Classical' 'Lily' 'Peppermint' 'Taiwan Sparks' 'Dexter' 'Little Red Berry' 'Red Laser' 'Twinkling Moonlight' 'Happy Princess' 'Neptune' 'Starfish 'Grenadine Splash' 'City' Parentage: Adenium crispum x "obesum " complex hybrid.

Back to Gallery Cultivars of Rare Crosses or Unknown Parentage Here are a few oddballs that don't fit anywhere else. 'Beautiful Mule' 'Flame Tree' 'Bohemian Splash' 'Singapore' 'Candy Stripes' 'Crimson Picotee' 'Winter Remedy' 'Beautiful Mule' Parentage: Complex hybrid involving Adenium "obesum", swazicum, and crispum . ('Candy Stripes' x 'Black Raspberry') 'Candy Stripes' = A. crispum 'Famous Ancestor' x A. swazicum 'Perpetual Pink' 'Black Raspberry' = A. crispum 'Famous Ancestor' x A. "obesum " 'Black Ruby' Creator: Dimmitt 2003 Plant form: Naturally arborescent with thick trunk, major branches, and massive roots. Foliage resembles that of "obesum", except for more prominent white veins as in crispum. Deciduous. It can also branch basally and become a shrub. Flower: Round at first; with age the petals elongate and quill, becoming more star-shaped. Diameter at one week 84 mm, 35 mm petal width. Petals solid crimson-red outer halves, fading to pink at throat. Throat red with darker red strong nectar guides that extend onto the petals halfway to the tips. There are white calluses where each pair of petals fuse at the throat. (They turn red in older flowers.) Flowers continuously from mid spring through late autumn. Notes: I had high hopes for this cultivar when it was young. I love tree adeniums, and the flowers borne at eye level. Alas, it's completely sterile, hence the name. It seems to have no pollen, and it has never set a fruit. Worse still, although it roots easily from cuttings, it is exceptionally susceptible to root rot. I have lost many plants from watering once too late in the fall or too early in the spring. I don't sell it except to the most avid and diligent collectors. Above: The original seedling of adenium 'Beautiful Mule', 17 years old in an 18-inch pot. Far left: a new flower of adenium 'Beautiful Mule', showing excellent shape. Left: week-old flowers, showing how the petals elongate as the flower ages. The right photo shows more accurate color - crimson-red. Back to Menu Above: A grafted plant of adenium 'Bohemian Splash', about 7 years old. The original seedling is slow-growing. 'Bohemian Splash' (MAD639) Parentage: Complex hybrid involving Adenium boehmianum, "obesum", and crispum . A. boehmianum 'MAD193' x 'Happy Princess' Creator: Dimmitt 2010 Plant form: Vigorous (on grafts) upright shrub or tree with sturdy branches; tends to grow taller than wide. Deciduous. Flower: Round, 60 mm diameter x 26 mm petal width. Petals pink with many fine dark pink lines almost to the tips. Throat pinkish-red with prominent black nectar guides. Blooms prolifically from early summer to early winter. High flower count. Notes: This is my favorite boehmianum hybrid, because of its strong growth and profusion of colorful flowers. The great majority of boehmianum hybrids are weak and/or are very slow growing. They produce mostly inferior offspring in subsequent generations. Back to Menu Above: The flowers of adenium 'Bohemian Splash'. Left: A young grafted plant of adenium 'Bohemian Splash', about 2 years old. 'Candy Stripes' Parentage: Label lost; presumably Adenium crispum x swazicum . When this cross was made, the most likely parents were A. crispum 'Famous Ancestor' and A. swazicum 'Perpetual Pink' Creator: Dimmitt 2000 Plant form: Erect, arborescent, with large roots and thick main stems. Deciduous. Flower: Semi-star, 80 mm diameter x 27 mm petal width. Petals dark pink with 3 fine dark pink lines to the tips and numerous short streaks. Flowers age to light pink. Throat red with darker red nectar guides. Blooms prolifically during the warm months. Notes: The dark throat and short anther appendages indicate swazicum parentage (if it were boehmianum , it should contribute larger leaves); while the petal markings have to come from crispum. Neither species is known for having sturdy stems, so this erect plant is a treasure. This clone grows well from cuttings. I know of no other crispum-swazicum hybrids. Above: A new (left) and old flower of 'Candy Stripes'. Above: The original seedling of adenium 'Candy Stripes', 9 years old in a 24-inch box. Right: This hybrid of A. crispum x A. swazicum by JFR Exotics supports my conclusion about the parentage of 'Candy Stripes'. Photo: John Franklin Roosevelt. Back to Menu 'Crimson Picotee' Parentage: Primary hybrid between A. "obesum " and A. multiflorum . Creator: Dimmitt 1984 Plant form: Very large, erect shrub with thick, sturdy main branches and massive roots. Evergreen. Flower: Round-star, 70 mm diameter x 27 mm petal width. Petals white with broad bright red border. Throat white with few prominent nectar guides. Blooms sparsely but almost continuously year-round. Notes: I've made several "obesum"-multiflorum hybrids, but this was the only one worth keeping. The others were less vigorous, and flowered even more sparsely. Grows well from cuttings and makes a good grafting rootstock. Back to Menu Above: The original seedling of adenium 'Crimson Picotee', 10 feet tall in a 36-inch pot at 16 years old. Left two: the flowers of 'Crimson Picotee'. 'Flame Tree' Parentage: Complex hybrid of A. "obesum", swazicum, and somalense. ('Crimson Star' x A. somalense ) Creator: Dimmitt 1995 Plant form: Tree to at least 10 feet tall in 10 years, with thick cylindrical trunk. Roots not greatly swollen. Flower: Round/semi-star, 55 mm diameter x 20 mm petal width. Petals deep red, fading to near-white at the throat. Throat blackish-red with black nectar guides that extend halfway to petal tips as red lines. Notes: I have made only a few crosses with somalense, because I didn't have any good clones of the species until very recently. Such hybrids have little value as commercial pot plants because they get so big so fast. But they would make great landscape plants in tropical climates. I list this cultivar because I know of no similar hybrids. It also shows that somalense can contribute petal markings to hybrids. Do you have any somalense hybrids? Please contribute to our knowledge. Above left: The original seedling of adenium 'Flame Tree', 8 feet tall at 9 years old. Above right: The same plant at 17 years old, 10 feet tall in a 22-inch pot. Back to Menu Above: A 4-year-old cutting of adenium 'Singapore', already showing its conical caudex. 'Singapore' Parentage : Uncertain; possibly this is Adenium coetanum . See notes below. Origin: Introduced by the Singapore Botanical Garden in 1933. My plant is a cutting of Frank Horwood's clone from Abbey Garden. Plant form: Spreading shrub with conical caudex and swollen main stems. Evergreen. Flower: Very large, semi-star, 102 mm diameter x 30 mm petal width. Petals light pink with wide deep pink to light red margin. Throat white with few faint nectar guides. Blooms repeatedly during the warm months. Notes: This is the oldest named cultivar of adenium, dating to a time decades before adeniums became well known in horticulture. Albert Chan at the Singapore Botanic Garden showed the plant to the famous botanist Richard Eric Holttum. He identified the plant as A. coetanum , a taxon of questionable validity. There are a few herbarium specimens with this label that were collected from northern Uganda and Kenya south to northern Tanzania. Adeniums from this region are currently recognized as A. somalense in the north and A. "obesum " in the south. DNA analysis suggests that 'Singapore' is an obesum-somalense intergrade. Therefore it is probable, whatever its true identity is, that it originated in this region of East Africa. Frank Horwood succeeded in selfing his plant and obtained a handful of seedlings, which were fertile. All of the plants in the US labeled A. coetanum are probably descended from this one clone. Source: a 1980 letter from Frank Horwood . Above: The 4-inch flower of adenium 'Singapore'. Back to Menu Above: A 12-year-old cutting of adenium 'Singapore. 'Winter Remedy' Parentage: Adenium multiflorum x swazicum primary hybrid. (A. multiflorum 'MAD1' x A. swazicum 'Perpetual Pink' Creator: Dimmitt 1987. Plant form: Spreading shrub with massive roots. Semi-deciduous. Flower: Round/semi-star, 77 mm diameter x 27 mm petal width. Petals with wide medium pink margin, fading to near-white at throat. Throat red with no nectar guides. Flowers fade to light pink in a week. Inflorescence is indeterminate, produces buds and flowers for about 3 months. Winter blooming. Notes: This is one of a small number of winter-blooming adeniums. Above left: The flower of adenium 'Winter Remedy'. Above right: A 3-month old indeterminate inflorescense. The first flower was where my two fingers are gripping the peduncle. Back to Menu Above: The original seedling of adenium 'Winter Remedy' at 16 years old in a 24-inch pot. Cuttings grow the same massive roots in several years.

Adenium oleifolium Stapf Adenium oleifolium occurs in South Africa and extreme southern Botswana. It is the smallest species in the genus. The caudex is subterranean, the stems are scarcely succulent, and rarely reach a foot tall. Plants in cultivation have small flowers are usually pale pink, with yellow throats and prominent red nectar guides. The anther appendages are just shorter than the tube, or may be slightly exserted. Wild plants come in a wide range of sizes and colors from white through pink to dark red. Plant and foliage of A. oleifolium . The plant is in a 6-inch pot and is about 6 years old. Flower of A. oleifolium . Note the yellow throat and moderately long anther appendages. A. oleifolium selected for darker flower color. Three seed-grown plants of A. oleifolium, several years old. Nectar guides may extend partway onto the petals. Those of A. crispum usually extend much farther toward petal tips. The petals are often narrow, but not as quilled as those of A. crispum . Leaves of A. oleifolium are longer and narrower than those of A. crispum , and lack the white veins. Photos: David Palzkill. Adenium oleifolium in the Wild A population of A. oleifolium near Uppington, Northern Cape, South Africa. The flower collection at right shows some of the variation at this locality. Variable traits include flower size, petal color and width, presence and prominence of nectar guides, and length of anther appendages. The variation is much greater than in any other Adenium taxon that I know of. Photos: Dawie Human. Left: An old plant of A. oleifolium collected from the wild . In nature the caudex was below ground.

Plant Sales This page features rare species and cultivars that will occasionally be available (continental USA only) at sascactus.com . There are two groups of offerings: 1. Superior adenium cultivars that perform well in hot summer/cool winter desert and semiarid climates; most were bred in Tucson, Arizona. The list includes cuttings and grafts of my own best hybrids as well as some created by others that I think are special. Some are clones of outstanding wild-collected plants, and a few that have historical value. The propagules offered range from small cuttings and grafts up to larger groomed specimens. Most of the adeniums I will offer are from my exclusive breeding line. Almost all commercially available adeniums are A. "obesum " and its hybrids (primarily with crispum) . Most are bred for small size to fit into limited living spaces. They have been bred in tropical climates and are not necessarily cold-tolerant. The very popular double-flowered cultivars have been over-selected for flower characteristics, and their stems are usually not strong enough to hold the flowers upright. I have very different goals: Since 1999 my primary focus has been on plants that can grow large, even to landscape-size. (But they can be kept smaller with hard culture and pruning.) They're tetraploid (4n) hybrids of A. "arabicum " with A. "obesum " and often A. crispum too. Tetraploid plants tend to be more compact, with sturdier stems and thicker leaves, more tolerant of environmental stresses, and more disease resistant. I also select for plant quality - big caudexes and disease resistance, in addition to flowers that are well-shaped, numerous (high flower count per inflorescence), and bloom most or all of the year. These 4n cultivars grow well on their own roots; no grafting is needed. 2. I will offer other outstanding species and hybrids that are rarely available. See a partial listing below .

Shop Now Tillandsia 'Curly Slim' My hybrid of Tillandsia streptophylla x intermedia . Rosettes tend to be long and narrow with soft, twisted leaves. The shape varies greatly with culture. If grown dry in high light, rosettes will be compact with tightly twisted leaves. With less light and more water, rosettes grow more elongated and the leaves are less twisted. To produce the most charismatic specimen, grow it with generous water and fertilizer until it begins to flower, then let it dry out and watch the leaves twist and coil. Shop Now Opuntia alta 'Fruit Punch' An extremely vigorous plant that can attain six feet tall and twice as wide in less than 10 years. Unlike most prickly pears, this clone grows pads throughout the summer. It flowers massively in April-May; each terminal pad can produce more than 20 buds that open into big purplish-red blooms. More flowers appear sporadically through summer. Culture: Native to south Texas, so it needs more water than most desert prickly pears. Hardy to at least 12 F. Origin: Opuntia alta is a hexaploid (6n) species that originated as a natural hybrid between O. engelmannii lindheimeri and O. stricta . In 1999 Tom Wiewandt gave Mark Dimmitt a pad of a plant he collected near McAllen, Texas. It was the most colorful prickly pear he saw there, with reddish-purple flowers. Mark Dimmitt grew about 100 seedlings from this plant, and selected this clone as the best of them. Note: This is different from the Colorado plant of the same name. It's also different from 'Citrus Punch'. Available now Opuntia 'Tucson Ruby' The plant looks like an Engelmann prickly pear when not in flower.

Dimmitt Adeniums is the comprehensive website for genus Adenium. We cover: plants in the wild, cultivars, care, and much more all from the mind of the master gardner Mark A. Dimmitt. This website is dedicated to the genus Adenium , commonly called adeniums and desert roses. My main purpose is to showcase their diversity both in the wild and in cultivation. I also provide guidance to cultivating the plants in hot, arid climates, based on my 40+ years of experience. The content was compiled by Dr. Mark Dimmitt of Tucson Arizona, with images and information contributed by many plant explorers and growers all over the world (credited in the photo captions) . The site was designed by Brian Rasmussen . I intend this website to be a comprehensive source of knowledge about Adeniums. I welcome your comments, corrections, and especially additions of new photos and information beyond what is already here. 'Beautiful Mule' 'OMG!'
