My white calla lilies, from last year, produced yellow calla lilies this year. Is that possible? The white ones were planted along with a salmon colored one in the same pot last year. I removed them in fall, washed them, let them dry, and put them in in basement during winter. I live in zone 4. This year, I planted them and currently, I have 6 coming up in the same pot and they are all yellow.

I suspect the pot actually had several colors planted in it. These may have been dormant prior and now are growing.
I have had a few reports of this happening. It is common for garden centers to put 2,3 and 4 different colored bulbs in a pot.
It's a beautiful pot and appears very healthy.
