'Almost White' - clean white with slight ruffle and small green throat.
'Asha' (Arizona Group x obesum) - light pink with darker margin, 4-5 in. wide, slight ruffled with overlapping, rounded lobes. Known from Dr. Ashish Hanseti of Bombay. A popular and breakthrough hybrid with the largest flower yet seen in the genus. Since the Ariziona has obesum in it, this is correctly considered a backcross to one parent.
Arizona Group (obesum x swazicum) - a cultivar group for hybrids of this cross. Typically plants are vigorous, root rot resistant compared to species, and mostly rich pink to rose-red in flower colors. 'Crimson Star' is one nice clone of this group. Named clones will give a more predictable effect.
'Black Ruby' - rose-red with distinct dark purple margins to 25-30% of the surface. Round overlapping lobes. This is a very stunning, wonderful combination of colors. It is not black margined but the color is very dark.
'Blue Hawaii ' - light purple, rounded overlapping lobes. 8cm diameter, strong plants. A unique color.
'Bolero' - plant strong and erect, flowers large, dark pink, petals very rounded.
'Boyce Thompson (swazicum) - dark purplish flowers with bright pink, slightly overlapping acute lobes. Known from the Boyce Thompson Arboetum, AZ USA.
'Calypso' (obesum x swazicum) - bright deep magenta pink, 4cm wide, whitish center. Strong upright plants. Named in FL USA.
'Candy Stripes' - light pink with darker pink to near red stripes and sectors.
'Cherry Marshmallow' - plants strong, caudex rather large, bright cherry red flowers, whitish center, pin-wheel shape.
'Chor Monkol' - dark red with white star-type center.
'Crimson Picotee' - flowers white with strong contrasting rose-red margins, about 50% of each color. Very bold and lovely among the bicolors. It is not a subtle shading!
'Crimson Star' (Arizona Group) - flowers very large to 3.5 in., dark rose-red, at times one of the closest to a true red.
'Dan-NubANan' - dark pink with lighter lobe centers. White margined leaf for extra interest.
'Dark Ruby' = 'Weiss Red'.
'Darng Bang Yai' - new growth white speckled green, flowers light pink with much darker, contrasting margins. Thailand mutant.
'Darng Chang Puok' - leaves greyish-green with wide pink to white margins and some sectors. Chimera easily 50% of some blades.
'Darng Num Anan' - leaves narrower, tongue-like, blunt-tipped, thin pink to white margins.
'Darng Tarng Chang Puok' - compact growth, leves oval, broadly margined and sectored cream to white, chimera 30-50%.
'Darng Thong' - leaves obovate, greyish-green with margins yellow that fade to cream.
'Desert Rose' - common name of species A. obesum and the same as it.
'Endless Sunset' (Arizona Group) - plants erect, flowers dark pink, very large, petals rounded, blooming for a longer than normal period.
'Evelyn Marie' - flowers dark pink, petals round, overall a star-like flower
'Grumbley's White' - white, 3cm wide, greenish throat, vigorous plant. A very popular white.
'Had Yai' (swazicum x ?) - bright magenta.
'Highland Red' - red flowers. A listed name and one parent of 'Sunset'.
'Hilo Beauty Variegated' - thin white margins to each leave. Used to breed in variegation.
'Hybrid Pink' (swazicum x obesum) - bright pink fading lighter. A valid name should be assigned.
'Kan Ni Ka' - pink with darker or reddish margins and greenish throat. Rounded overlapping lobes.
'Kao Maoradok Lok' - white with yellowish throat. Nice glossy leaf.
'Keaw Sa La Pa Nouk' - leaves shorter, rounded apex, at first light yellow to cream, becoming flecked green. Flowers medium pink with white throat, margins darker and undulate.
'Lipstick' - bright red, long tube, 5cm wide.
'Little Ruby' (Arizona Group) - flowers dark rose-red, margins a tad richer, smaller diameter than 'Crimson Star' and thus more in scale for some bonsai applications.
'Mahogany Variegated' ('Nil') - leaves dark orangish-red, roughly mahoghany toned, if give rich light. May have flecks of other colors. Originated by John Lucas, FL USA and grown since in Thailand as 'Nil'. In other words, the American originator's name is both earlier and the only valid name. 'Nil' is a rename and most importantly one not approved by the clone's discoverer.
'Manee Nil' - red leaf, very showy, large caudex. If the same as 'Nil', the correct name would be 'Mahogany Variegated'.
'Mike's White' - pure white lobes, greenish throat.
'Mombasa' - pink with darker near red margins. Smaller plants with good basal branching as young plants. Forms as good caudex cultivation which is not true of all selections. Collected in Mombasa. There are of course other plants from Mombasa but this name is used for an A. obesum clone.
'Nap Anan' - large red with white throat. Flowers to 3 in. wide. Has been sold under 'New Red'.
'Nat Ti Da' - light pink or white tipped pink or white tinged pink. Quite variable colors on one plant.
'Nil' = 'Mahogany Variegated'
'Nil MatlaKal' - red tinged leaves and a darker red midrib. Few if any flowers.
'Nub Anan' - dark bright pink with reddish or darker margins. Ruffled. Nice white margined leaf is a plus.
'Peachy Pink' - scarlet pink with a slight ruffle
'Perpetual Pink' (swazicum) - flowers mostly a uniform pink, very small throat darkish purple, blooms for a longer period. It's a very refined, more uniform version of the species with longer displays.

'Shaba' - said to develop a thick, fat caudex in record time.
'Shocking Pink' (swazicum) - bright pink with round, overlapping lobes.
'Singapore' (arabicum) - deeper pink, more floriferous than species. Flowers 10cm wide - twice species normal dimensions! It also blooms longer, up to 10 months a year. It is related to var. coetanum or the same as it.

'Sunset' ('Highland Red' x obesum) - rose-red tinged a faint orange perhaps, white star in throat.
'Swazbo' (swazicum x boehmainum) - light pink with purple throat. Cultivar names made of such hybridization of species names are not permitted so it needs a renaming.
'Tom Thumb' - hot pink with yellow center. Miniature type 2 in. wide flowers.
'Tony Huang Red' - flowers a dark, rich red.
'Tricolor' or 'Three color' - almost invariably these are grafts of three different color forms and not a true cultivatr.

'Volcanic Sunset' - flowers red with lighter red center, rather large.
'Weiss Red' - solid dark red. Same as 'Dark Ruby'.
'White Flower' or 'White-flowering' - pure white flowers. Other white clones are listed above. 'Grumbley's White' is a proven named white clone and we'd go with that one before generic "white flowering" stock.
'Yak Darng' - leaves very narrow and long, greyish-green, margined and sectored white. Blades are thinner than most other known variegates.
