Our 2 year old Tricolor Hoya plant wasn't growing until my brother told me to put it outside a few months ago.
Update on my daughter in Houston: they borrowed a boat to go back to her boyfriend's family's house. It still has 12" of water and is in the path of the draining levee, so it will be a few more days before there will be a chance for drainage.
I've never seen one of these plants. What a gorgeous color the new growth is. Heaven bless your daughter for reaching out to others in the midst of her own challenges.
Nice to see it bursting into life, such a pretty colour too. It's nice to know your daughter is safe but it sounds as if there is a lot of recovery work to do.
