Nursery contributed plant descriptions

A dazzling “must” for the DRY GARDEN! Hundreds of silky 1½” Poppy flowers go for broke from mid-Summer to Fall & longer on this heat & drought tolerant mistake-proof Mediterranean native. Beautifully held all around & from top to bottom on a billowy 30”x 36” much branched form, the attractive soft blue-green stems & leaves provide a winning harmony with the enchanting blooms. Easy as pie, it’s insect & deer resistant & not fussy about soil. For longest (till November) bloom, deadhead & give it a bit of Summer water. Self-sows.
