I inherited some plain red and some yellow tulips which grow to 18" tall and come back every year (now for over 30 years), but I obviously have no idea what variety they are. This in clay soil, too. Maybe I should set about propagating and selling them! As others have said, apart from these all of the ones I buy only last 2 or 3 years at best.
