The unknown plant put out a lot of broad leaves and flowered recently. Viola, it is a Eucrosia bicolor and not a Eucharis grandiflora.
Whilst there were about 8 buds altogether, I wasn't particularly impressed by it because the size of the small red flowers just does not commensurate with the leaf size. I would have preferred it to be the large, white flower Eucharis.
I will be giving it away to someone who appreciates it more.
