Having said that... I suppose that the following could decently suit:
Adsila (meaning "Blossom"), Algoma ("Valley of Flowers"), Kineks ("Rosebud"), Lomasi ("Pretty Flower"), Mansi ("Plucked Flower"), Mausi ("Plucks Flowers"), Ogin ("Wild Rose"), Polikwaptiwa("Butterfly Sitting on a Flower"), Posala ("Farewell to Spring Flowers"), Rayen ("Flower"), Sihu ("Flower"), Yamka ("Blossom.")
