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 duratii saxatilis 'Chaco Flaco' This selected clone from the Chaco region of Paraguay has long, narrow rosettes and huge inflorescences. It's slow-growing so rarely offered for sale. Shop Now Tillandsia 'Twisted Reality' Description This is a hybrid of Tillandsia (bulbosa x streptophylla ) x 'Gorgon'. It has the best of its parents: a bulbous base and twisted leaves. An equally distorted small red inflorescence appears when the rosette is mature. With time it will grow into a tangled ball. 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. Modest size; grows to 2 feet tall and four feet across in several years. Flowers in April-May. The color varies with the weather from blood-red orange; both colors may be present at the same time. Culture: Needs no supplemental water in Tucson (10-12 inches annual rainfall). Hardy to at least 12 F, Note: This plant volunteered on Mark Dimmitt's property. An Engelmann prickly pear apparently crossed with one of the red-flowered plants in his ya rd. Available now Right 2: The flowers of 'Tucson Ruby' vary with the weather, blooming darker on cooler days (< 90-95 F). Sansevieria stuckyi giant form The colony shown is 8 years in the ground and the tallest leaves exceed six feet. They reportedly can grow even taller. This clone was collected by Jim McConville (#165) in Botswana, USDA #19459, HBG #50502. Available summer 2025 Tillandsia duratii 'Chaco Giant' Another selected clone from the Chaco of Paraguay. It has the largest, most succulent rosettes that I have seen in this species. The inflorescences are sparsely branched. This cultivar has never been offered for sale. Available again in 2026? Commiphora monstruosa A slow-growing natural bonsai with twisted stems and peeling bark. This 13-year-old plant has been pruned but not trained. Rooted cuttings available 2027

Adenium " arabicum" x crispum hybrids As far as I know, Miles Anderson of Miles’ to Go Nursery is the only person who has successfully made this F 1 cross. He got only five viable plants, but they were fertile. They have the large caudexes and sturdy, erect branches of “arabicum ”; the small plant size, foliage, and flowers were heavily do minated by the crispum parent. Third generation plants that I grew from these plants still showed the striped petals, and mostly quilled petals. Some of these are larger, up to five feet (1.5 m) tall. In my opinion the main value of this line is contributing smaller size and striped flowers into the “arabicum” x “obesum” x crispum line . These hybrids are apparently tetraploid, because they cross only with other 4n adeniums. Above left: The star-shaped flowers of some clones have flat petals, but most will quill in a couple of days (right). Left: One of Miles Anderson's original F1 plants of Adenium "arabicum" x crispum. The caudexes are very large compared to plant size. Photo: Miles Anderson. Miles Anderson's F2 crosses of Adenium "arabicum" x crispum also have relatively huge caudexes, but the flowers are still quilled. The promise of these plants is to get cripsum 's patterned flowers and smaller plant size into the tetraploid arabicum-"obesum " line. Plant at left is 5 years old in a 14-inch pot. Footnotes

Adenium "obesum" x "arabicum" hybrids First generation hybrids between this tetraploid and diploid species are very rare, probably because the odd number of chromosomes (3n, triploid) in the fertilized ova can’t pair up during cell division. Out of more than two hundred controlled pollinations, I have obtained fewer than 10 viable seedlings. All of these F 1 (primary, first generation) crosses are tetraploid and strongly resemble the “arabicum” parent. It’s apparent that “arabicum ” occasionally makes triploid ova, which, when fertilized by a haploid “obesum ” sperm cell, forms two pairs of each homologous chromosome (Richard J. “Jake” Henny, written communication). Therefore F1 hybrids are 3/4 "arabicum", which explains the dominance of this species' characteristics in the hybrids. Fortunately, some of the hybrids are fertile. The F 1 and subseque nt generations of this breeding line have impressive hybrid vigor, and can rapidly grow into huge specimens. The first one, named ‘Arabian Ruby’ is the most vigorous adenium that I have ever seen. At ten years of age, it filled a 42-inch (107 cm) pot with a multi-stemmed base almost three feet (91 cm) thick. Cuttings of this plant are also vigorous and very caudiciform . Most other plants of this interspecific hybrid are also very large. In subsequent generations the “arabicum ” parentage remains heavily dominant in plant form. The “obesum ” parentage shows in the large, brightly colored flowers (three to four inches, 76-102 mm wide), and unfortunately, a tendency to weak stems. After four generations of selection, some excellent reds are showing up. See the superior cultivars page for a gallery of these hybrids. Adenium 'Arabian Ruby' is probably the first hybrid between A. "arabicum" and A. "obesum". It is also the most vigorous adenium that I've ever encountered. The seedling grew rapidly to enormous size, a classic example of hybrid vigor. See the gallery of superior cultivars for more details on this and other hybrids of this line. Above: Flowers of Adenium 'Arabian Ruby'.

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!'

Double Flowered Cultivars

Adenium "arabicum " Balf. f. Adenium "arabicum" occurs in a narrow strip along the southwestern coast of the Arabian peninsula. The specific epithet is enclosed in double quotation marks because it is an incorrect name. See the page on Nomenclature Issues for details. Plants in cultivation are almost all spreading shrubs with huge, squat caudexes (but see the section on wild variation below). They are usually vigorous and can grow to several feet tall and wide in 10 years with generous culture. Stems are sturdy and upright or ascending. Foliage is quite variable in size and shape, but are usually recognizable by aficionados of the genus. Leaves may be shiny-smooth or softly hairy; this trait has no taxonomic relevance. Compact and dwarf plants exist in cultivation and in the wild. Flowers are usually 1.5 to 2 inches wide, with petals varying from narrow and pointed (star-shaped flowers) to broad and overlapping (circular flowers). Flowers are almost invariably some shade of pink at the margins and fading to white at the throat. The throat is white or yellow, with or without nectar guides. The anther appendages extend to the edge of the throat or a little beyond. Most plants flower profusely in spring before leafing out. Large plants tend to be evergreen. Some varieties flower mainly in summer, and selected clones also flower sporadically throughout the year. Adenium "arabicum " 'Yemeni Giant ', 3 years old in 12-inch pot. They can grow even faster. Flower of Adenium "arabicum " plant at left . An Adenium "arabicum " with star-shaped flowers Adenium "arabicum " 'Sheila Collenette ' from Saudi Arabia. This plant is in the ground under a fiberglass roof. It had just survived a few nights of 22° F (-5° C) with only minor tip damage. The plant is 8 years old with a caudex more than a foot wide. Adenium "arabicum " 'Sheila Collenette ' from Saudi arabia, same plant as one at left flowering a year later. This plant has glabrous leaves; these are found scattered among the more common hairy-leafed plants. Adenium "arabicum" from Jebel Shada, Saudi Arabia. This plant was the fastest growing in a batch of seedlings. It is 11 years old in a 42-inch pot; the caudex is almost 3 feet across. Adenium "arabicum " flower on a plant from Jebel Shada, Saudi Arabia. This one lacks nectar guides. Adenium "arabicum" 'Hansoti Dwarf' has reddish flowers. This clone has been in cultivation in India since at least the 1930s. It most likely originated on the Aden Peninsula, the type locality for A. "arabicum" . Adenium "arabicum " flower with dark color. This A. "arabicum" has near-white flowers. Back to Top Left: Adenium "arabicum" grows large enough to make splendid landscape plants in tropical climates, such as this one in Florida USA. Photo: Ray Lemieux "Thai socotranum" & other dwarf A. "arabicum " Adenium "Thai socotranum ", also called "Thai soco", are not related to Adenium socotranum . They are in fact dwarf forms of A. "arabicum " bred in Asia. They are extremely popular, and there are many named varieties. The names of Thai soco plants are treated as cultivars, but they are probably not. They are defined by their physical forms that are created not only by their genetics, but largely by how they are groomed (pruned and trained) to look like miniature examples of wild Adenium socotranum (Ashish Hansoti, written communication). Thus the names are more like the terms that define bonsai styles. There are dwarf populations and isolated individuals of A. "arabicum" in nature. There are also dwarf cultivars that were developed outside of Asia. See below and the superior cultivars page. Left: Adenium "arabicum " 'Petch Na Wan ' was purchased as a small seedling in 2009.

Adenium somalense Stapf Adenium somalense occurs in Somalia, Ethiopia, Kenya, and a bit into adjacent nations. The most common form in cultivation grows a tall, conical, succulent trunk, but there are also shrubby forms with subterranean caudexes. Only A. "arabicum" and socotranum have larger caudexes. The most identifiable vegetative characters are the conical caudex and light-colored veins in the leaves. The flowers are rather small, 1 to 2 inches wide. The flowers typically have narrow pointed petals (star-shaped flowers) that are white or pink with dark pink or red borders. Prominent nectar guides in the throat extend onto the petals as fainter lines, not as bold as those of most A. crispum flowers. It is not common in cultivation in the USA, but is fairly popular in more tropical countries. Adenium somalense in a 30-inch pot at a nursery in Bangkok, Thailand; the plant is 10 years old. The cutting at the base is in a 4-inch pot. Adenium somalense grown in Tucson, Arizona. It's 9 feet tall at 17 years old from seed, but has lost its roots to rot twice because of cold weather. The plants I have from Shaba National Park in Kenya are very prone to root-rot. Note the 12-inch ruler at the base. Flowers of 2 Adenium somalense clones from Shaba N.P., Kenya.
