here is a pic of my new rosebush, the name is something angel face. It is a floribunda rose. Very pretty lavender blooms. It has about 10-12 buds right now. Also here is a pic of my branching tulips.
You need to find your rose a bigger home to allow it more room to stretch it's feet - roots. That container will be too small soon. You can pot it into a 5 gallon container to start of with. Or, better still, find it a spot in the garden with a minimum of 6 hours of direct sunlight per day.
