clematis 'Sieboldiana'


The Clematis 'Sieboldiana' is a stunning flowering plant known for its remarkable blossoms. Its flowers are particularly eye-catching, boasting a creamy-white base color that serves as a backdrop for a prominent, frilly center comprised of purplish-pink staminodes, which are petal-like structures. This contrasting center tends to draw the eye and gives the flowers a two-toned effect that is very attractive in garden settings. The leaves of 'Sieboldiana' are green, and they typically have a glossy sheen, providing a lush background that further accentuates the beauty of the blooms. The plant has a vining habit, which means it can climb and drape over structures such as trellises, walls, or fences, adding vertical interest and a touch of elegance to any garden space where it is grown.

  • water dropWater

    The Siebold clematis should be watered deeply and consistently, aiming for about 1 inch of water per week, whether from rainfall or manual watering. During hot or dry periods, you may need to water twice a week, ensuring that the soil remains evenly moist but not waterlogged. It's preferable to water this plant in the morning to allow any excess moisture on the foliage to evaporate throughout the day. Utilize a soaker hose or drip irrigation to deliver water directly to the base, minimizing moisture on the leaves and blossoms. Adjust watering based on rainfall, lessening the amount when natural precipitation provides adequate moisture.

  • sunLight

    Siebold clematis thrives in a location with full sun to partial shade, requiring at least 6 hours of sunlight daily. The ideal spot allows for morning sun, which is gentler, with some shade during the hottest part of the afternoon to protect its delicate flowers. An eastern-facing garden spot would be well-suited for this clematis, offering ample light without the harsh intensity of late-day sun.

  • thermometerTemperature

    Siebold clematis prefers temperature conditions that range from 55°F to 75°F for optimal growth. It can tolerate temperatures as high as 85°F but may require additional shade and moisture to prevent stress. The plant can survive in temperatures as low as 20°F, but it is best to provide some form of winter protection if it regularly experiences freezing conditions. An ideal environment would maintain moderate temperatures and avoid extremes.

  • scissorsPruning

    Pruning Siebold clematis encourages vigorous growth and abundant blooms. Prune in late winter or early spring, removing dead or weak stems and cutting back the remaining stems to strong buds about 1 to 2 feet from the base. This plant flowers on current year's growth, so annual pruning is necessary to stimulate its best performance. The best time for this is when buds begin to swell but before active growth starts, typically when temperatures begin to stay consistently above freezing.

  • broomCleaning

    As needed

  • bambooSoil

    For the Texas Clematis, the best soil mix is well-draining, moisture-retentive loam with a pH of 6.0 to 7.0. Amend the soil with compost and possibly some perlite or vermiculite to enhance drainage.

  • plantRepotting

    Texas Clematis should be repotted every 2-3 years to replenish nutrients. Younger plants may need repotting more frequently if they outgrow their containers.

  • water dropsHumidity & Misting

    Texas Clematis enjoys moderate to high humidity levels, ideally around 50-70%. It can tolerate lower humidity if other conditions like watering and shade are appropriately managed.

  • circleLife cycle

    Florida Clematis 'Sieboldiana' starts its life cycle as a seed which, under appropriate conditions, will germinate and establish a root system. Following germination, the seedling grows into a vine with a woody base, developing long stems that climb up supports with the aid of leaf tendrils. During the growing season, this herbaceous perennial plant produces large, distinctive white flowers with purplish-brown center staminodes, typically from late spring to early autumn. After pollination, the flowers give way to feathery seed heads which disperse the seeds. In preparation for winter, the above-ground part of the plant dies back, while the root system remains dormant until the next growing season. The cycle is repeated when the plant emerges from dormancy, sprouting new shoots from the crown in spring.

      Spring to Summer

    • The Clematis florida 'Sieboldiana', commonly known as the Florida Clematis, is best propagated by semi-hardwood stem cuttings taken in summer when the plant is actively growing. To propagate by this method, one should select a healthy, non-flowering stem and cut a section 4 to 6 inches (approximately 10 to 15 centimeters) long just below a leaf node. Remove the leaves from the lower half of the cutting and dip the cut end into a rooting hormone to promote root development. The cutting should then be inserted into a pot filled with a moistened mix of peat and perlite or a sterile seed-starting mix, ensuring that the leaf nodes where the leaves were removed are buried beneath the soil surface. The pot should be covered with a plastic bag or placed in a propagator to maintain high humidity, and it should be kept in a bright, indirect light location until roots have established, which typically takes several weeks. After rooting, the new plant can be transferred to a larger pot and gradually acclimatized to outdoor conditions before planting out the following spring.
