The Perfect Pennsylvania Plants for Your Garden

The Keystone State has an inspiring amount of floral diversity. Many different types of native plants can thrive in Pennsylvania's unique climate. For experienced or newbie gardeners looking to create a garden of PA gems, it’s vital to know which native plants will flourish.

With the proper knowledge and resources, your Pennsylvania garden can become a beautiful haven for wildlife and showcase the state's natural beauty.

Gardening Conditions

Pennsylvania experiences four distinct seasons: hot summers, cold winters, and plenty of rainfall. The state has a humid continental climate, meaning it’s well-suited for a wide range of plants that can handle seasonal changes.

Native plants in the Keystone State have adapted to the climate conditions over hundreds of years. Local perennial plants are ideal for local gardens, requiring less water, fertilizer, and pesticides. They also support local wildlife, such as bees, butterflies, and birds, making them a win-win.

Gardening Tips

Selecting the right plants also means looking at factors like how much sunlight you get in your garden, plant water needs, and bloom times.

Gardeners should consider selecting a mix of plants that bloom at different times of the year to satisfy pollinators. They should also consider their own limitations in terms of time and maintenance capabilities.

Soil

Soil plays a significant role in the health of garden plants. Most native PA plants prefer well-draining but highly fertile soil, like loamy soil. High-quality soil is essential.

For those starting a garden from scratch or looking to revitalize it, procuring the best soil is a must. Try searching “garden soil near me” to find the best options in the area.

Test the soil before planting to ensure sufficient pH and nutrient content. Most Pennsylvania soil tends to be slightly acidic, which works well for different types of native plants. If the soil needs to be adjusted, consider compost or mulch to improve its structure and fertility.

Watering

Native Pennsylvania plants are drought-tolerant once they have been established. However, newly planted flowers, shrubs, and trees require regular watering until their root systems fully develop.

Watering new plants deeply and less frequently encourages profound root growth—just be careful not to overwater and get stuck with root rot.

Mulch helps retain soil moisture, regulate temperature, and reduce the number of weeds in a garden. It also slowly breaks down and adds organic material to the soil.

Weeding

Nobody likes weeds in their garden, yet weeds can be a persistent challenge in any climate or location.

Regular weeding is vital to keeping a pristine garden while ensuring invasive plants don’t outcompete native flowers for water and nutrients.

Hand-pulling weeds is usually the most effective method of removing them, especially in smaller garden beds.

Many blame Goldenrod for causing allergies, but the plant is a critical pollinator and the perfect option for adding seasonal color to a garden. Its bright yellow (or “golden”) flowers bloom in late summer and fall.
