Singapore Obtusa, from my limited experience, having had it a couple of years, is certainly more cold sensitive and prone to black tip(fungal die back). By cold sensitive, I mean compared to regular plumerias(rubra).

I personally will no longer subject mine to temperatures in the forties...50 degrees and up is the safe zone for me...and that goes the same for Dwarf Singapore Pink.

So how well does it do indoors over the cold months (Fall/winter)? Or do they actually go dormant up here?

I would recommend a different cultivar if possible.

Couldn't agree with Tony more about S.O. Although I have no recollection of having black tip issues with my DSP.

Hi phy2ek I would not take for my Singapore obtuse but they are picked about temperature I never let my greenhouse go below 60 in the cold season. First _ kms is correct if you can't keep it warm you may need to get another cultivar
