Probably, Guest. Ours have leaves and well developed flower buds.

Which type of arum lilies were these? The coloured types are very tender and unlikely to have survived the cold winter. The ordinary large white type are extraordinarily hardy and come back year after year and multiply. They will grow both in the water, in boggy ground, and even in dry soil.
The ones in the picture have been there for five or six years and have survived minus 21 and minus 18 this winter.
