There are literally hundreds of varieties of peony flower, in every shade from pink to red to white to lilac and every shade in between. The time that peonies will bloom will depend in part of the variety selected and in part of the growing and care conditions provided. There are three stages of peony bloom times. Some peony varieties will bloom in the early spring. Others will bloom in the early summer. And still others will bloom in the later summer season. Selecting the right peony variety often comes down to determining which varietty bloom best in which temperatures, and selecting a variety that will grow well in your USDA plant hardiness zone and garden conditions.

Understanding how peonies grow and bloom is a key to successfull cultivation. Peonies grow from rhizomes, which are thick roots that contain a mixture of nutrients to nurture the plant as it grows. It often takes time for the new peony plant to grow and become established, and until it does so, it will likely not produce blooms. The larger the rhizome and the greater number of "eyes" or bud points it has, the sooner a new peony plant is likely to bloom. The earliest a new peony plant is likely to produce blossoms is the second season after it is planted.
To make sure that your peony plants produce blossoms, take care that rhizomes are planted shallowly in the soil. Planting no more than four inches below the soil surface is ideal. Be sure that soil is well draining or rhizomes may rot. Ideal soil pH should be between 6.5 and 7.0 and that peony plants are watered well and fertilized often with a low nitrogen fertilizer.
