The carpark at the Singapore Botanic Gardens HQ was planted with this scrambling vine Uvaria grandiflora (synonym: U. pupurea, U. rufa; common name: Salamander's Son, Large-flowered Uvaria; Family: Annonaceae) for many years now. The span of its coverage is so extensive but the flowers are far and few in between.It is definitely not a climber I would plant at home because of its few flowers. A link is attached below for reference:
