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 awful)
• Follow the narrow road till it ends at the Plumeria Grove and stables.

There are hundreds of plumeria trees in the grove. They begin with the whites and miscellaneous, then the pinks, rainbows, yellows, and 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 plumerias in this grove are rare, if not unknown elsewhere.

Most of the trees are only tagged with an acquisition number, with no indication of a cultivar or variety name to be found. The following list relates the acquisition number to the cultivar name as well as we can determine. Unnamed varieties are noted as color. We make no guarantees. Many plants have the same number. We list only those with duplicate numbers and different flowers. Many plants are untagged. 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.
