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 zaidi flowers.

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

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