On the three white flowers in the first photo, I think they might be a type of cactus flowers? Check out the included link below for image of cactus flowers. But with out more information, I’m only speculating. We need to see the plants stems to narrow down the ID. https://www.cactuspro.com/photos/Cactaceae/Echinopsis/albispinosa/4198.html

Another Salviar cultivar. https://www.anniesannuals.com/plants/view/?id=4722

Hi Claire, I can’t be certain of you Salvia to tell if it is hardy in your winter. Best you get in touch with the folks of the Master Gardener at the CSU Extension Office in Douglas County from the link below to help you further in growing Salvia in your region. Best wishes to you Claire! Laura http://douglas.extension.colostate.edu/gardening-horticulture/master-gardener/

Thank you for the ID of the Salvia Coccinea. I have it in a pot for now, but should I put it in the ground in the fall?

On the first photo, please show us the side view of these flowers stems where they are associate to the plant. The leaves in the background look like they are from the ‘Elephant bush’ (Portulacaria afra)plant, its flowers are not the same as these three white blossom are shown here. 2- A type of sage (Salvia). I can’t tell which cultivar this is. Check out the included link below for one the species. https://plants.ces.ncsu.edu/plants/all/salvia-coccinea/
