SelecTree: Tree Detail
BLUE MARBLE TREE
Photo Locations: Fairchild Tropical Botanical Garden - Miami, FL and Hawaiian Islands
Blue marble tree is a large tree that is more appropriate for campuses, parks and botanical gardens than home gardens. When mature this species has a high open crown, and thin buttress roots at the base. They do better in high rainfall areas in valleys and near stream banks on the windward side of the Hawaiian Islands. During summer, iridescent blue fruit and reddish-orange fallen leaves can be found beneath trees. In Hawai'i the seeds are used for leis. In Southeast Asia they are used to make Hindu prayer beads or necklaces. The wood is also valuable for timber. The grove of blue marble trees at the Hindu Monastery above Kapa’a on Kaua'i is particularly impressive. Elaeocarpus angustifolius has a HPWRA (Hawai'i Pacific Weed Risk Assessment) score of 4 (Evaluate).
Has fragrant Flower.
Native to Australia.
