Plant question - Sedum rupestre (Reflexed Stonecrop)
Thanks for contacting the Master Gardeners. I have attached a fact sheet for your reference. I grow the sedum and have seen some dying out this year due to the long, snowy winter and now lots of rain. The plants like full sun if possible. Keep track of your watering and let the sedums go dry for a longer period of time and reduce the amount of mulch around the plants.
Let us know if we can continue to assist you. Good Luck
