I have bought the bulbs of calla lilies that you can get at Lowe's, Wal-Mart, etc. I will plant them and I might get a bloom off each bulb. The blooms are small also. I have seen on tv (gardening shows, etc) where the calla lily plant is huge and has multiple blooms on it. The flowers are also bigger. They have always been white in color. Is this a different type of calla lily?

I would appreciate any help.

Thanks!
