My flowers are made with glass seed beads. They will Last forever since you do not water or plant them however they may get dusty. Just use a cotton cloth, swiffer duster or a feather duster to keep the dust off of them. If the dust is heavy, use just a little bit of water on a cloth and using it roll the beads with your fingers in the cloth. Try not to get the stem wet. Do not put the flower under running water! Flowers are assembled with floral tape and if wet will be damaged.
These flowers need very little care which makes them more of a pleasure to have around.
