Frequently Asked Questions

Whether you're new to gardening or a seasoned green thumb, we have a list of common perennial flower questions. If you have a question regarding one of our perennials we have for sale at our garden center, feel free to contact us to learn more.

  • The best time to plant perennials, including outdoor perennial plants, is typically in the spring or fall. This timing ensures that your selection of perennial flowers or plants can establish themselves well before the extreme temperatures of summer or winter.

     

    By planting in either season, you give your perennials the best chance to thrive year after year. Spring planting allows them to settle in and develop strong root systems before the summer heat sets in, while fall planting lets them establish roots before winter dormancy. This ensures they're ready to burst back to life when the growing season returns.

  • Determining the "longest-lasting" perennial can depend on various factors such as climate, soil conditions, and maintenance practices. However, some perennials are known for their longevity and ability to thrive for many years with proper care.

    One example is the Peony, which can live for decades and often outlasts many other plants in the garden. Peonies are known for their showy, fragrant flowers and are relatively low-maintenance once established.

    Other long-lasting perennials include Daylilys, which are prized for their hardiness and ability to bloom profusely year after year, and perennial geraniums, known for their long flowering season and adaptability to different growing conditions.

    Ultimately, the longevity of a perennial plant depends on factors such as proper siting, soil preparation, watering, and ongoing care. By selecting robust, well-adapted varieties and providing them with the right growing conditions, you can enjoy beautiful perennial gardens for many years to come.

  • One of the easiest perennials to plant is the black-eyed Susan (Rudbeckia hirta). These cheerful, daisy-like flowers are drought-tolerant, thrive in full sun, and can adapt to a wide range of soil conditions.

    Another easy-to-grow perennial is the Echinacea. It's also drought-tolerant, attracts pollinators like bees and butterflies, and adds a pop of color to the garden with its vibrant pinkish-purple flowers.

    Sedum varieties, such as Stonecrop, are also excellent choices for low-maintenance gardens. These succulent plants are extremely drought-tolerant, thrive in sunny locations, and come in a variety of shapes and sizes to suit different garden designs.

  • When it comes to hardiness, the Siberian iris often stands out as one of the toughest perennials. These plants are incredibly resilient, thriving in a wide range of soil types, including moist or even boggy soils, making them ideal for various garden conditions.

    Another exceptionally hardy perennial is the Hosta, which is known for its ability to withstand shade, drought, and pests while still producing lush foliage year after year. Hostas come in numerous varieties with different leaf shapes, sizes, and colors, making them versatile and popular choices for many gardeners.

    Additionally, ornamental grasses such as Miscanthus and Switchgrass are renowned for their durability and ability to withstand adverse growing conditions, including heat, drought, and poor soil.
