Mambo GP Blue Petunias are low grow approved. Consider the Mambo’s the multiflora counterpart to the genetically dwarf grandiflora Limbo series. Like their grandiflora cousins, Mambo GP is the next generation of breeding that emphasizes garden performance along with its naturally low growing plant habit. This attribute allows Mambo GP Blue Petunias to be produced with little to no growth regulators, resulting earlier flowering and larger blooms than most typical multifloras. At the end of the summer when petunias are known to get rather leggy, Mambo GP maintains it compact height but will have a slightly wider plant spread than its predecessor, filling in gardens and landscapes more quickly.
