Japanese Wisteria Wisteria floribunda 'Lawrence'
Wisteria floribunda 'Lawrence' is a striking woody climbing plant, known for its cascading clusters of flowers. It displays tightly-packed, long, drooping racemes of beautiful pea-like flowers that can range from a delicate pale blue to a more vibrant purplish-blue color. These graceful flower clusters hang elegantly off the plant and can create a dramatic floral display during its blooming period in spring. The leaves of Wisteria floribunda 'Lawrence' are pinnately compound, meaning that they are composed of multiple leaflets arranged on either side of a common axis. They are a vibrant green color, which contrasts beautifully with the blooms and provides a lush backdrop throughout the growing season. The leaflets themselves have a smooth texture and are oval-shaped with a pointy tip, giving the foliage an overall delicate and feather-like appearance. The twining stems of the plant are another key attribute, enabling it to climb trellises, arbors, or other support structures, making it an excellent choice for vertical gardening. The bark on older stems becomes rugged and gnarly, adding character to the plant even when it is not in bloom. In the autumn, the leaves may turn a yellow color before dropping, signaling the end of the growing season. Overall, the appearance of Wisteria floribunda 'Lawrence' is one of an enchanting and romantic plant, bringing a sense of elegance and old-world charm to any garden setting with its pendulous florals and verdant foliage.

Japanese Wisteria should be watered deeply once a week, allowing the soil to dry out slightly between waterings. During hot, dry periods, increase watering to twice a week. Each watering session should provide the plant with approximately one to two gallons of water, depending on the size and maturity of the plant. Ensure that the water penetrates deeply into the soil to encourage a strong, deep root system. Consistent watering is particularly crucial during the first few years of growth to establish the plant well.
Japanese Wisteria thrives best in full sun, needing at least six hours of direct sunlight each day. The ideal spot for the plant is one where it receives unfiltered, direct sunlight throughout the majority of the day, which promotes vigorous flowering and growth.
Japanese Wisteria is hardy and can survive in temperatures as low as 10 degrees Fahrenheit, though frost can damage young growth. Ideally, it prefers a range within 60 to 80 degrees Fahrenheit. Protect the plant from harsh winter winds to prevent damage to the vine.
Japanese Wisteria needs to be pruned twice a year to control its growth and promote flowering. Prune in late winter to prepare the plant for spring growth, cutting back last year's growth to two or three buds. A second pruning should occur in midsummer, after flowering, to tidy the shape and maintain the structure. Regular pruning helps prevent the wisteria from becoming invasive and encourages more prolific blooms in the following season.
Japanese Wisteria, including 'Lawrence', thrives in a fertile, moist but well-draining soil mix with a pH of 6.0 to 7.0. A blend of loamy garden soil, compost, and perlite or coarse sand would provide the ideal structure and nutrients for healthy growth.
Japanese Wisteria 'Lawrence' should be repotted every 3 to 4 years. It's important to increase the pot size gradually and prune the roots slightly to encourage new growth.
- Humidity & Misting
Japanese Wisteria 'Lawrence' does well in average outdoor humidity levels and doesn't require specific humidity conditions for healthy growth. No need to alter natural outdoor humidity for this plant.
- Suitable locations
Ensure bright light, ample space, and strong support for climbing.
Plant in full sun, provide sturdy support, and space for climbing.
- Life cycle
Japanese wisteria 'Lawrence' begins its life cycle with seed germination, which requires a period of stratification to break dormancy. Upon sprouting, the young seedling emerges and starts developing a strong root system and foliage in its juvenile stage. As the vine matures, it enters a vegetative growth phase, characterized by the rapid extension of its twining stems and the development of compound, pinnate leaves. After several years, the plant reaches maturity and begins to produce its characteristic long, pendulous racemes of fragrant flowers, typically in shades of blue to violet, during the spring season. Following pollination by insects, it sets seed pods that mature over the summer and burst open in the fall or winter to complete the reproductive cycle. The plant continues to grow and can reach great ages, with some specimens living for over a century, continuing to expand and produce flowers annually.
Propogation: The popular method for propagating Wisteria, also known as Japanese wisteria, involves taking softwood cuttings in late spring or early summer. To do this, choose a healthy, new growth shoot and cut a 4 to 6-inch (10 to 15 cm) section just below a leaf node. Remove the leaves from the lower half of the cutting, and dip the cut end into rooting hormone powder to encourage root development. Then, plant the cutting in a pot filled with a mix of half peat and half perlite or sand to ensure good drainage, gently firming the soil around the stem. Place the pot in a warm, bright location out of direct sunlight and keep the soil consistently moist. Roots typically develop within a few weeks, after which the new wisteria can be gradually acclimated to outdoor conditions before planting in its final location.
