Notes
It is 45 degrees outside and it’s been raining. It’s pretty cold but not crazy windy. It’s been drizzling all day not to heavy rain. The plant seems to be holding up well I wonder if this is the peak of its health since all the leafs are a rich green though the flower does seem to have a bit a wilting.
