I only have Maya. It blooms pink.

It seems like some of them do not produce flowers at all or probably do at a unusually low rate. I would look to get only the varieties advertised with pictures of flowers.

My guess for why they don't bloom is they may have been irradiated to produce mutants (e.g. variegated ones). It's relatively common practice in Thailand to irradiate plants so these variegated mutants cultivars show up. Their horticultural industry is well known for producing variegated plants. Compare to Hawaii which probably has a longer history of cultivating plumerias but not one well known variagated cultivar has come up into the mainstream.

Thank you so very much for the Info!!! I will not waste my Money then after all....They have beautiful variegated leaves but if it doesn't produce flowers then maybe it's just Ornamental then...
