I have brought some annual plants into my plant room to see how long they would last. I can see my impatient may last-I did have flower buds until they dropped off, which tells me I'll have to give em some epsom salt water to hold the buds next time. I did manage to get a petunia to flower. red Petunia ( photo / image / picture from petunia's Garden ) I'm hoping this little one will hang on till next spring. Only time will tell. I'll enjoy anything I can get to flower for now.
