Daisy is right, none of your plants are Calla Lilies.
We've been inundated lately with plant ID questions regarding plants grown from seeds shipped from China from websites like aliexpress and eBay sellers. There is definitely a seed selling scam happening in China.
I'm so sorry that you were sent the wrong seeds.
to NGA, though!
I hope someone here will have some recommendations for a good source of Calla seeds for you.
