Lilies and Orchids won't produce flowers to harvest

I have a room in my sim's house where she grows various plants. Every morning, all my plants produce flowers and fruits, except my lily and my orchid plant. Both are good quality, they just don't produce flowers. I even check at 5am/6am sims time and I see all the plants bloom at the same time, except those two. 

I play on PC and I have never used mods.
