Nice list Cinta. Hope you will post photos when they arrive.
The main thing to know about the tender type of sedum, and other tender succulents, is to give them very little water in the winter, and a bright window to sit in.
S. linear 'Variegatum' needs some protection in zone 6, even though it is listed as hardy to that zone. Freezing and thawing would be tough on it. Maybe site the container up again the foundation of the house?
Sedum corsicum This is a synonym for
Sedum dasyphyllum. It should be hardy in your zone 6.
S. hakonense 'Chocolate Ball' Growing zone is all over the map as to hardiness. Does anyone out there grow this one in zone 6? I have it in zone 8, it tends to go winter dormant for me. Could be because of excessive rain during winter and spring here. I have placed it in a new bed filled with sandy loam to see if it stay happier in winter time.
S. sieboldii This one will grow in zone 5. Some of our members grow this in zone 5. Should be an easy one for you. Tabby & picklepuff can give you more information on how they place it in the garden (soil, sun, etc). Also whether or not it is everygreen or deciduous for them.
Hope this was of some help to you. Hopefully others will come along from colder climates than mine with more information on how they grow them.
