Nothing in nature blooms all year long, don't expect yourself to. Any plant lady worth her dirt knows that plants require love and care, not just water. Mugs are 16oz double wall, BPA free. This design is a vinyl decal, don't worry it won't just come off with regular use. The vinyl I use is outdoor sign quality and is considered a permanent application. Not sure about vinyl products? Shoot me a message I'd love to yell you why it's the best.
