Dieffenbachia seguine 'Tropic Marianne' is a cream-centred Dieffenbachia with broad leaves carrying pale yellow to ivory centres and deep green margins. The upright cane-like habit gives height as the leaves overlap into a bold, full outline. The light centre dominates each blade, while the green border keeps the foliage clearly framed. New leaves carry the same framed pattern as the cane gains height. Because the sap contains calcium oxalate, keep the plant away from pets and children. Grow it in gentle filtered light and warmth, with an aerated mix that holds light moisture between waterings.
