Great question Jennifer.
Color can be variable depending on the variety of semp and the season. Some have color year round, others just in spring, summer or fall. Also growing conditions can determine the amount of coloring present.
What cultivars are you talking about?
Depending on the ones you recieved they can look vary similar upon arrival, after being in a dark box.
Many of mine are mostly green right now, some are starting to color up for fall/winter coloring.
