Wow, never saw a (Sinningia speciosa) staked up right like that, quite impressive,
I guess your plant bit light-deprived, that's why it is leggy and thin. Often time they die down after some time, do not throw away, since there is tuber underground, keep it on the dry side, and it will re-sprout, after some rest. You could also cut tuber to propagate, or if you wants lots of plants, seed will be good, their seeds are so small like dust.
