Odd one out

[nyreeholmes]

Please can anyone let me know which of these is the odd one out Winter aconite, Christmas rose, Christmas box or Wood anemone Thanks in advance

As far as I'm aware Christmas box is not a plant.

[woofgang]

I think that sarcococca confusa is sometimes known as christmas box

[molly]

Sorry, woofgang's right. Winter aconite has yellow flowers, the others have white flowers?

I'm not sure but does'nt the wood anemone flower in the summer and the others in the winter?

[molly]

Not summer, but March and April. But that could be the answer, they flower at a different time.
