In what way do cultivars typically vary?

Cultivars, which are cultivated varieties of plants, typically exhibit a range of variations that include growth rate and disease resistance. Different cultivars can have distinct growth habits—some may grow rapidly while others are more slow-growing. This variability is crucial for gardeners and landscapers, as it allows for the selection of plants that will thrive in specific landscapes or under particular conditions.

Moreover, cultivars often have differing levels of resistance to diseases and pests, which can significantly influence their performance and longevity in a garden or landscape setting. Choosing a cultivar with good disease resistance can lead to healthier plants that require less intervention, making them more suitable for specific environment or management practices.

While color and shape, habitat, climate tolerance, and leaf size are also important characteristics, the combination of growth rate and disease resistance provides essential practical benefits for landscape horticulture, making the choice of cultivar more relevant for achieving optimal outcomes in a gardening or landscape context. Understanding these factors helps horticulturists and gardeners make informed decisions about plant selections for their specific environments.
