Rollback is Walmartâs marketing lingo to describe a product where the price has been temporarily reduced (which means you should buy it now, before the price goes back up! Clever, huh?). The name implies the price of the item has been ârolled-backâ to an earlier time before a price increase on the item was instituted.
If you notice any leftover annual plants on clearance in the summer, youâll notice that the moss rose plants are usually just as lovely as they were in May, a testament to the plantâs toughness. The succulent leaves of the portulaca are another clue to the wonderful drought tolerance of this low growing annual flower. 1  Many varieties have semi-double to fully double flowers that resemble miniature roses. Flowers come in hot colors, like yellow, orange, red, and bright pink.
