With great regrets, we’re canceling the 2021 SCPS Hawaiian Plumeria Festival, traditionally held over Labor Day weekend. The health and safety of our community must come first, and in looking at our resources and spaces, we simply can’t keep all our vendors, volunteers, entertainers, and guests safe, particularly at an event as large and varied as our festival.

We look forward to gathering with you in safer times in 2022.

Congratulations to Lori Kilmer for winning the 2019 Best In Show with Jeannie Moragne!

IMPORTANT: Make sure you cut the tags exactly 2¾” wide and 5½” long!

Download the Flower Show Color Reference guide, with directions on which blooms to enter in which category.

Please keep in mind that there are separate categories for seedling entries. A seedling is a plant grown from a seed by the exhibitor. Plants grown from sports or acquired as anything other than a seed (a cutting from the dump in Hawaii or a sport) should all be entered in sections I through V. If you did not nurture that tiny little plumeria seed into a full-grown plant, you should not be entering in Sections VI, VII, VIII, or IX and your entry can be disqualified. But you can still enter it in Sections I, II, III, IV or V (except Class 8). Growing seedlings takes hard work and persistence and seedling developers get separate classes to recognize their hard work.

If you’re still having problems figuring out which category to enter, check out the Flower Show Entry flowchart.

Please bring as many blooms and inflorescences as you can. Flower entered in normal classes can have a duplicate (second) flower entered in the Scent Division.

While there is no limit on the number of blooms you can enter, you may only enter one bloom of each variety in a single class. You’re not allowed to dump one tree’s worth of blooms in one Section and Class in hopes of getting a prize.

You CAN enter blooms that are unidentified. Just put “Unknown” or “No ID” in the name field on the form.

We provide all the single flower vases, the tumblers for the inflorescences, and entry tags.

JUDGING for all classes will begin at noon on Saturday.

AWARDS Rosette ribbons will be awarded to each entry that is judged the Best in Section and Best in Display Class.   1st, 2nd, and 3rd Place winners will be awarded ribbons for each class in the Flower Sections.  Each Display Class will receive 1st, 2nd, and 3rd.   Since the floral arrangement and lei display classes have different classifications, each classification will have 1st,2nd, and 3rd place ribbons with  Rosette ribbon awarded to the best of all classifications . All display classes are not eligible for the Jeanette Mattson Best in Show Award. 

The Jeanette Mattson Best in Show Award Eligibility:Only the Best in Section in the Show classes (I through IX, excluding Display classes) are eligible for the Best in Show award, unless the Best in Section is the same variety that has won the Best in Show award already in the recorded history of the SCPS flower show.If the Best in Section happens to be the same variety as a previous Best in Show winner, the judges will not include it in the final judging for Best in Show.   A replacement entry will not be picked for the section, and the judges will choose from less categories. (for example, if there are two varieties of section winners who have won Best in Show in the past, there will only be 7 section winners that will be judged for Best in Show, rather than 9).Please continue to enter your blooms, even though the variety of your bloom has won the Best in Show award in the past.  Best in Section blooms are all recognized and winners will receive our prestigious rosette awards and Certificates with a photo of your winning entry.  We will present the Best in Section awards at our annual luau!
