I was use to rhizomes with the larger calla's. These came as bulbs the size of peas. I planted them 3" deep in a pot, they have now come up. Look nothing like the regular calla's. I looked online for a pic but they only showed me older leaves with blooms. These leaves are shiny and on long stems sort of elongated oval with a tip on them.
I got them from China and I guess I will have to wait and see.
Would love to see yours Thanks

Sounds like you may have Z. rehmannii. In the cut flower industry they're often referred to as "mini callas". The foliage is more elongated and doesn't have the arrowhead shape of large callas (Z. aethiopica is the large white calla most often seen). Blooming sized tubers are typically larger than peas, so it may be a year or so before you see blooms (I'm not aware of any smaller or truly "miniature" varieties on the market).

I've often found self set seedlings from mine that sound much like you describe.

Here is what has grown from my bulbs.
