In May, most stores begin to receive their "real" hydrangea shipments. Over here Lowes, for example, only stocked a limited inventory prior to May.. Merrit Supreme and another whose name escapes me but in May they should be getting a more varied inventory. The exact moment of these deliveries is anyone's guess so call often and ask for the person who orders or who can check what inventory is due soon.

Thanks Luis. You were right, I called Lowes and they said that they will be getting a shipment sometime next week. So happy!
