Sultan Orange is a dahlia that we received in Sultan, WA from an established farm that was going out of business.  It is a variety that we have been unable to determine the name of (may possibly be Orange Cushion).  It produces prolific quantities of bright orange, open-center blooms.  Sultan Orange is a healthy plant and produces hardy tubers that store well in and out of the ground in our area (Skagit county, WA).
 
Single dahlia tuber, grown at RainySunday.  All tubers are dug, divided and stored in the fall.  Tubers are inspected for viable eyes, individually labeled, and packaged in vermiculite for shipping.
