Question
I inherited a plant when my mom passed away and she always referred to it as a crown of thrones.  It did real well this summer but once in the house it is now loosing its leaves.  I live in new england and it is in a sunny window. I can't find any information on line about the care for these plants.  can anyone help?

Answer
Annette,

Here is some information I found on your plant:

Also, your plant will go dormant and lose some leaves as most Euphorbia's will. Just DO NOT over water. Let the soil dry between waterings and it should be OK.

Sincerely,

Greg
