I have been waiting two years for my hoya to bloom. This spring it decided to go for it. I love the smell of the blooms as they remind me of the flower shop in the town I grew up in. My mom also grew hoyas. All of hers bloomed a pure white with pink centers. Mine have had several colours on the same plant! Even the bud clusters were different colours before they bloomed. Maybe they spent the two years working out which colour they wanted to be lol!
