Orchids are important to many public gardens. Orchid-themed shows draw large crowds, and orchid collections are the focus of several gardens. Cattleyas refers to the orchid genus Cattleya and closely related, often cross-compatible genera. Cattleyas were once the archetypal orchids and grown extensively as cut flowers. Orchids are culturally and politically significant for Singapore, however Cattleyas are underrepresented in new orchid introductions and registered hybrids despite their charismatic appearance. More widespread cultivation and breeding of Cattleyas in Singapore faces challenges including a reduction in flower production and quality in the lowland tropical climate of Singapore. Information on Cattleyas is also spread across disparate sources. This capstone project is a consolidated resource for choosing and breeding Cattleyas suitable for Singapore and the tropical lowlands. It was developed through reviewing informative sources on Cattleyas both in the context of Singapore and in various countries. Key findings include lists of Cattleyas that are suitable for cultivation in Singapore, climate data of the native habitats of some Cattleyas, and recommendations for choosing and breeding Cattleya for Singapore.
