Patience is virtue. Only a small increase in height since yesterday and the edge of the spathe is not as tight though it has not yet started to pull away.

Now we are just waiting and watching. We can detect a slight odor at the edge of the spathe.

Will it bloom today? There is a chalky residue on the stalk which indicates it will bloom very soon.

Growth is beginning to slow which means bloom will open just days from now.
