Roses Only Grow in Certain Climates

Grade 3

Roses are a common flower that people give to one another during Valentine’s Day. Valentine’s Day occurs in the month of February, during the winter season. However, roses are unable to grow in the state of Maryland during the winter because of the cold weather and climate. So, how do gardens, farms, and stores in Maryland get the roses they need during Valentine’s Day? We will explore the answer to that in this lesson.

Graph of Monthly Maximum Temperatures in Maryland and Ecuador

Have students analyze and interpret the graph. Compare and contrast the temperatures of Maryland and Ecuador throughout various times of the year. Ask students what patterns they recognize from this graph. How does this information help us understand why roses can grow in Ecuador during the winter season and not in Maryland?
