Adenium arabicum Hybrids

Adenium arabicum is very reluctant to cross with other species, so hybrids are rare. The arabicum parent contributes its gigantic caudex; obesum contributes darker flower color than the usual arabicum pink. A. crispum is dominant in its hybrids, even with giant arabicum.

Dozens of attempted crosses between Adenium obesum 'Black Ruby' and A. arabicum finally produced one viable seed. The result was 'Arabian Ruby'. It flowers year round with very large, light red flowers.

'Arabian Ruby' grows very fast and gets huge. The plant above is the original seedling at 7 years of age; it is in a 36" pot and has a caudex 12" (30 cm) across. It has grown dramatically in the two years since this photo was taken. Click here to see it at 10 years old.

Above: Adenium 'Bouquet' is an F2 obesum-arabicum hybrid that bears up to 38 flowers per inflorescence, with 10-12 medium red flowers open at once.

Adenium (obesum X arabicum) F2 'MAD 399' seedling flowering at less than a year old in a 6" pot. It already has a substantial caudex.

Adenium (obesum X arabicum) F2 'MAD 364', at two years of age in an 18" pot. Click here to see the same plant at 8 years old.

'Bouquet' at 6 years old in an 18" pot.

Adenium (obesum X arabicum) F3 'MAD 400'. Excellent reds are beginning to appear in the 3rd generation, still with the great arabicum caudex. Some are also everblooming.

Adenium 'MAD 348' is almost identical to arabicum except that it has big red "obesum" flowers. This plant is 8 years old.

A. arabicum X obesum hybrids also produce some fine pinks. 'MAD 382'

Adenium obesum X arabicum, a second generation hybrid ('MAD 432') with a more treelike growth form. Note the large trusses of flowers.
