I'm familiar with all except for "alba variegata". I know Alocasia alba, but not a variegated form. Alba and gageana are smaller growers compared to Odora and Macrorrhizos. The latter two can get large with proper care. Jurassic dark is a selection of Alocasia plumbea and it is a somewhat smaller version of a macrorrhizos type. Gageana will produce many offsets, as will the macrorrhizos. Odora , alba and Jurassic dark are less prolific in terms of offset production. The larger plants are heavy feeders, but all of them benefit from regular or constant fertilization.
