Aloe macroclada Baker is an endemic species to Madagascar known as “vahona”, whose distribution is limited only in the highlands, the central part of this country. The plant is used by local population for its many virtues, but the most important uses, causing the growing demand for plant material comes to the cosmetical and parapharmaceutical industries. However, the A. macroclada culture is still in ornamental stage in private and public gardens when the crops begin to be difficult because the resource is limited. To cope with the growing demand of users, this study was achieved to develop a technical route for the propagation and cultivation of A. macroclada and to propose an approach for the sustainable management of this resource. The results show the possibility of propagation from seed. The germination rate varies according to the experimental conditions: 50% in nursery, 65% in the greenhouse and 78% in vitro. Vegetative propagation is difficult. The survival rate after transplantation field also varies from 40 to 85% according to the different conditions tested. For the social aspect, 55% of surveyed small farmers are ready for planting A. macroclada, 25% for the enrichment of in situ population and 20% for the rational management natural stock of this resource.
