May 1st indeed is Lei Day in Hawai'i !! What a beautiful display of imaginative lei on display at Kapiolani Park , should you happen to be there on that day.
One year I had a jade plant lei. Gorjus against a pale bue mu'umu'u ... like the sea surrounding us. (Long, Deep, Sigh of Longing -e)
You may order Dendrobium lei delivered by air from Mauna Loa catalogue,
As for me, I have two lovely lei of silk so real looking people want to touch and always ask "Is that real?"! One orchid, one ginger. Expensive available in Hawai'i only, leastaways I haven't seen them anywhere else.
By the way no plural in Hawaiian (tenuous word-related try)
one lei is a lei, ten lei are still lei.
