What type of plant can be planted before the last killing frost in the spring and is known for its ability to resist frost?

The choice of a hardy plant is correct because these plants are specifically adapted to withstand cooler temperatures and can survive mild frosts without sustaining damage. Planting hardy plants before the last killing frost allows gardeners to take advantage of the early spring growing season, ensuring that these plants establish their roots and thrive once warmer temperatures arrive.

Hardy plants include various flowers, vegetables, and shrubs that can handle the stresses of late frosts. They are distinguished by their ability to acclimate to cooler temperatures in the early spring. For instance, many common garden crops like spinach, kale, and pansies fall into this category, making them ideal candidates for early planting.

Other options, such as annual plants and tender plants, typically cannot survive frost. Annuals complete their life cycle in one growing season and are particularly sensitive to frost, while tender plants cannot endure chilly temperatures and would likely be damaged or killed by frost exposure. Perennial plants, while they return year after year, may still vary in their frost tolerance. However, they do not have the same level of resilience against frosts as hardy plants do. Thus, the distinction of a hardy plant being able to resist frost is key to the choice made here.
