Clematis 'Bonanza', is a vibrant flowering perennial vine known for its showy display. It features large, vibrant flowers that usually exhibit a pale to deep lavender or mauve hue, infused with a gradient that can range to lighter shades toward the base of each petal.

The plant has a robust nature that, once established, provides a spectacular visual interest with its seasonal blossoms. The overall impression of the Clematis 'Bonanza' is one of ornamental charm, adding seasonal beauty and vertical interest to gardens and outdoor spaces without commenting on the specifics of its size.

  • water dropWater

    For the Clematis 'Bonanza', water the plant deeply to ensure the soil is moist, but not waterlogged. Initially, water the plant 2 to 3 times a week to help establish roots; then, reduce watering to once a week, giving the plant about one gallon of water per session. During hot and dry periods, increase watering frequency as needed to maintain soil moisture but avoid overwatering. Ensure proper drainage to prevent root rot. Mulching helps retain moisture and reduce the need for frequent watering.

  • sunLight

    Clematis 'Bonanza' thrives best in a spot where it receives at least six hours of sunlight each day. However, the plant prefers its roots to be shaded, so it's ideal to provide some coverage at the base with mulch or low-growing plants. The bright and indirect light will support the plant's vigorous growth and enhance blooming.

  • thermometerTemperature

    Clematis 'Bonanza' performs best in temperature conditions between 45°F and 80°F. It can tolerate temperatures down to 20°F, but growth may be inhibited below this mark. To encourage optimal growth and flowering, protect the plant from extreme temperatures and drafty areas.

  • scissorsPruning

    Prune Clematis 'Bonanza' to promote healthy growth, prevent overcrowding, and enhance flowering. The best time to prune is late winter or early spring before new growth begins. This variety falls into Pruning Group 2, which means it should be lightly pruned to remove dead and weak stems and to shape the plant. It will typically involve cutting back the stems to just above a healthy pair of buds about 6 to 8 inches above ground level.

  • broomCleaning

    As needed

  • bambooSoil

    Clematis Bonanza thrives best in a well-draining soil mix with a pH around 6.5. For an optimal soil mix, combine two parts garden soil, one part well-rotted manure or compost, and one part gritty material such as perlite or coarse sand. This ensures good drainage and fertility, supporting robust growth and flowering.

  • plantRepotting

    Clematis Bonanza, typically grown outdoors, does not need frequent repotting. In containers, repot every 2-3 years or when roots outgrow the pot, doing so in spring before active growth starts.

  • water dropsHumidity & Misting

    Clematis Bonanza prefers a moderate humidity level, similar to outdoor conditions. Consistent humidity levels without significant fluctuations are beneficial, though it tolerates a range found in most garden environments.

  • circleLife cycle

    Clematis Bonanza, often known simply as the Clematis, begins its life as a seed or can be propagated from cuttings. It germinates and emerges as a seedling, developing a strong root system and initial leaves. As the plant matures, it enters a vegetative state, where it produces stems that climb or trail, relying on a support structure, and large green leaves. The Clematis then enters its flowering stage, typically from late spring to early autumn, showcasing vibrant purple flowers which are attractive to pollinators. After pollination, the plant produces seed heads that can be dispersed to continue the life cycle. In winter or during dormancy, the above-ground portions of some varieties may die back, with the root system remaining alive to regrow in the following growing season.

    • Propogation time

      Spring-Early Summer

    • Propogation: The Clematis 'Bonanza', with its striking flowers, can be propagated mainly through softwood cuttings in the late spring or early summer when the plant is actively growing and the stems are still tender. For the most popular method, select a healthy shoot and cut a section about 4-6 inches long, just below a leaf node. Strip the lower leaves, leaving only two or three at the top. Dip the cut end into rooting hormone powder to encourage root growth. Then, insert the cutting into a pot filled with a mixture of equal parts peat and perlite or a well-draining potting mix, ensuring the leaf nodes where you removed the leaves are buried. Water the cutting thoroughly and cover it with a plastic bag or place it in a propagator to maintain high humidity. Place the pot in bright, indirect light and keep the soil moist, but not waterlogged. Roots should develop in several weeks, after which the new plant can gradually acclimate to normal environment conditions before being planted out.
