Mike

Lisa Marie Presley just sent a "thank you" bouquet to the florist that decorated Michael Jackson's tomb with sunflowers -- because if there's one thing a florist needs, it's 更多 flowers.

TMZ has learned Presley sent the 花 to sunflowerguy.com -- along with a personalized card that said, "Thank 你 so much for donating the beautiful flowers."

As we previously reported, the florist sent 更多 than 1,500 sunflowers to Forest Lawn Cemetery on Friday , after Lisa Marie begged MJ's 粉丝 to do a better job of decorating Michael's tomb.
