Tulips are one of the easiest flowers to grow successfully in the garden. Plant bulbs in the fall and even a novice gardener can expect to see beautiful flowers in the spring. Tulips are classified as a perennial flower. This means that a tulip should be expected to return and bloom year after year. But we all know that this is not always the case. If tulips are perennials, then why don’t they behave as perennials? The answer is really quite simple. Tulips are native to Eastern Turkey and the foothills of the Himalayas. They will perennialize best in conditions that match the cold winters and hot, dry summers of their native region. In addition, species and botanical tulips perennialize best. Hybridizing sometimes diminishes a tulip’s ability to perennialize, other times it enhances this ability.
