The Dean Conklin Plumeria Grove is named in honor of the late Mr. Dean Conklin, an employee of the City and County of Honolulu, Parks and Recreation Department. The collection is located in Koko Crater on the island of Oahu, Hawaii. It is owned and managed by the City and County of Honolulu, Parks and Recreation Department.

By plumeria enthusiasts, known simply as Koko Crater, it is somewhat difficult to locate. Though once you’ve been there, you’ll never forget the path or the collection.

Follow these simple steps:

• Drive past Diamond Head on Kalaniana’ole Highway
• Continue past Hawaii Kai and Hanauma Bay
• Slow down as you pass the surfer area called Sandy Beach
• Take the first major left turn after Sandy Beach, Kealahou Street
• Drive through a part of the Hawaii Kai residential area and Golf Course
• Watch for an obscure left turn, to Koko Crater Stables and Botanic Gardens (the road and surroundings look aweful)
• Follow the narrow road till it ends at the Plumeria Grove and stables.

There are hunderds of plumeria trees in the grove. They begin with the whites and miscelaneous, then the pinks, rainbows, yellows, and finally the reds. Many of these trees are large enough to climb, though we DO NOT recommend that you do, since you can get hurt or even worse damage a world class specimen plant. Many of the plumeria in this grove are rare if not unknown elsewhere.

Most of the trees are only taged with an acquisition number, with no indication of a cultivar or variety name to be found. The following list relates acquisition number to cultivar name as well as we can determine. Unnamed varieties are simply noted as to color. We make no guarantees. Many plants have the same number, we list only those with duplicate numbers and different flowers. Many plants are untaged, we don’t list these at all. When we list ‘cultivar’ type, it means, in our opinion, it may or may not be the named cultivar, but bears striking similarity. Documented by John Murry in 1996.
