It was such a coincidence that i read this today because last night i was reading a site that i read a lot of info i had no idea about.Such as S. autumn joy or H.autumn joy.

I didn't realize there were so many different species that sedum's had been moved around in or is it mainly the upright sedums.Some of the species on this site i had never heard of but was familiar with the plants as syn.sedum.
I looked for autumn joy this fall to plant in a bed,i had no luck finding it but the 2 i did buy were Sedum spectabile's not really sure about the spectabile.Does anyone know what it means or where it came from.I had someone tell me it was the plants with brightly colored blooms,i bought 1 named Sedum spectabile Neon,with beautiful neon pink blooms.
