The popularity of succulents as ornamental plants has increased in recent years. This is primarily because of their unique geometric shapes, which form a rosette, coupled with their ability to retain high levels of moisture. These features make ornamental succulents suitable as landscape plants as they can withstand extreme conditions and as potted plants for indoor spaces as they require minimal watering. Appropriate propagation techniques are important to increase production rates and plant quality in the shortest time possible. These ornamental plants may be propagated in various ways, both sexually, via seeds, and vegetatively, through a number of methods, such as stem cuttings, leaf cuttings, and micropropagation. In this review, methods for the propagation of ornamental succulents are described, including post-propagation care and management. Propagation aspects on which limited information is available are also highlighted. Potential areas for research required to produce data to further improve techniques, conservation, and rapid propagation efforts are discussed.

Growth and development of succulents were studied in response to two leaf cutting types, the tip and base, using four Echeveria species (E. ‘A Grimm One’, E. ‘Momorato’, E. pulvinata ‘Frosty’, and E. pulidonis) and the planting position, either upright and faced-downward, using Graptoveria optalina. The shoot diameter (mm), height (mm), and number of leaves were significantly affected by the leaf cutting type. Results revealed that the shoot diameter of buds from base leaves were significantly larger by 4 - 9 times than those of buds from tip leaves. Shoot height of buds from tip leaves either not developed or reached a maximum of 2.29 mm while buds from base leaves had an average height of 11.61 mm from E. ‘Mamorato’. Using base leaves allowed to obtain roots and leaves for all selected succulent species after 60 days from planting. Regarding planting position, upright planted and downward-facing plants showed significant differences: buds from upright planting showed taller shoots, greater number of leaves which in turn gave higher visual quality rating and superior color reading using Hunter’s Cielab compared with buds in downward-facing planting position. Planting succulents in an upright position led to well-formed shoots and roots which had a high-quality rating and color evaluation compared with faced-downward planting producing etiolated and abnormal grown shoots. Based on these findings, we suggest that the use of base leaf cuttings and an upright planting position provides a rapid vegetative propagation method for selected succulent varieties.

With the purpose of selecting succulents that are capable of retaining their ornamental value under lower light levels of indoor spaces, this experiment was conducted in two different locations within an apartment balcony (0.0 m and 1.6 m from t he w indow) and u nder d iffering l ight intensities (13.5 μmol･m-2 ･s-1 and 96.4 μmol･m-2 ･s-1). Ninety-seven species of succulents from 23 genera were selected as experiment material, based on the criteria of propagation ease and affordable price. As a result, 37 species were selected as suitable for indoor decoration and consisted of 27 species (Echeveria macdougallii, E. 'Momotaro', E. 'Fun Queen', E. derenbergii, E. 'Pulv-oliver', E. multicaulis, E. lilacina, Crassula 'Buddhas Temple', C. mesembryanthemoides, C. ‘Moonglow’, C. ovata, C. ovata 'Gollum', C. ovata 'Tricolor', Aeonium arboreum 'Atropurpureum', A.sedifolium × A. spathulatum, A. sedifolium, Graptoveria 'Albert Baynes', × Graptoveria 'Silver Star', Pachyphytum oviferum, P. oviferum 'Momobijin', Sedum clavatum, S. morganianum, Sinocrassula yunnanensis, S. densirosulata, Kalanchoe tetraphylla, Cotyledon tomentosa, Adromischus cooperi) from Crassulaceae, 6 species (Haworthia fasciata, H. retusa, H. turgida var. longibracteata, Aloe perfoliata, A. juvenna, Gasteria gracilis) from Asphodelaceae, 2 species (Corpuscularia lehmannii, Faucaria bosscheana) from Aizoaceae, 1 species (Peperomia graveolens) from Piperaceae, a nd 1 s pecies (Sansevieria trifasciata ‘Hahnii’) from Asparagaceae. The majority (67.6% of the selected species) of the selected species had overwintering temperature of 0 – 5°C and while most of the selected species had fibrous roots, all species with thick roots were selected as suitable. Of the selected species, 78.3% had a growth rate of moderate level or faster, and 56.8% were summer growing type. Sixty species were found to be unsuitable, and included 5 genera from Crassulaceae (× Pachyveria, × Sedeveria, Graptopetalum, Orostachys, Monanthes) and o ne g enus f rom Asteraceae (Senecio).
