Photo Den. rigidum is found from New Guinea to Australia. It inhabits mangrove swamps, also on trees and rocks along riverbeds. The plant was recently moved to the genus Dockrilla. This is a mini plant with pseudobulbs usually 1-2" tall. The pseudobulbs grow in spreading clumps often with a climbing then pendulous habit. The blooms are cream colored with red/orange striping, approximately 3/8 to 1/2" in size. The flowers are fragrant, blooming can be from Spring to Fall though ours prefer Summer. It would seem that these plants are in bloom every time you turn around, a bonus for those with small collections. Literature suggests light in the 3000-4000FC range. Our experience with greenhouse grown plants shows that they seem do best in light of 2000-2500FC. Den. rigidum is an intermediate growing species. Temps should be typical, 60-85 degrees, night/day. The humidity levels should be fairly typical for Dens, 60-70% is ideal. Water thoroughly, not allowing the potting media to completely dry. Reduce slightly in winter. No rest needed. We prefer to grow these on horizontal mounts rather than in pots. The percentage of plants in pots that sulk seems to be about 20%, whereas mounted plants is about 1%. There seems to be a clear preference here.
