Clematis Broughton Star Clematis 'Broughton Star' (M/d)

Water

Clematis 'Broughton Star', also known as Montanas, should be watered deeply but infrequently to encourage a strong root system. Ideally, water the plant when the top inch of soil feels dry, which might translate to roughly once a week during active growth periods, particularly in dry weather. When you do water, aim for about 1 gallon per square foot around the base of the plant to ensure the deep roots have enough moisture. During the winter dormancy, reduce watering to match the plant's slower metabolism, keeping the soil only lightly moist.

Light

For optimal growth, Montanas prefer a location that receives full sun to partial shade. The best spot would allow the plant to bask in at least six hours of sunlight each day, while providing some shelter from the intense midday sun, especially in hotter climates. If you can, position it so that the roots stay cool and shaded while the vine itself receives adequate light.

Temperature

Montanas thrive in a temperature range that generally does not drop below 25 degrees Fahrenheit in the winter and can tolerate summer temperatures up to around 90 degrees Fahrenheit. The ideal temperature for vigorous growth would be between 65 and 75 degrees Fahrenheit. Keep in mind these plants are quite cold hardy and can endure brief periods of colder temperatures.

Pruning

Pruning Montanas helps to control their size, encourage healthy growth, and improve air circulation. Prune the plant lightly in late winter or early spring to remove any dead or damaged stems and shape the plant. After the first flush of blooms, prune lightly again if desired to foster a second set of flowers. Remember to always use clean, sharp tools to make precise cuts.

Cleaning

As needed

Soil

Clematis 'Broughton Star', commonly known as Montanas Clematis, thrives best in well-draining soil rich in organic matter with a pH ranging from neutral to slightly alkaline, around 7.0. A good mix would include garden soil, compost, and well-rotted manure or a balanced commercial potting mix combined with perlite for improved drainage.

Repotting

Montanas Clematis typically does not need frequent repotting and can thrive in the same container for several years. Repotting every 3-4 years, or when the plant shows signs of being root-bound, is sufficient to maintain its health and vigor.

Humidity & Misting

Montanas Clematis prefers moderate humidity levels but is generally tolerant of the typical range found outdoors. It does not require extra humidity measures as long as it is grown in an environment with natural air circulation.

Suitable locations

• Indoor

  Ensure bright light, limited direct sun, good air flow, and stake for support.

• Outdoor

  Plant in sun to part shade, provide support for climbing, mulch well.

• Hardiness zone

  4-9 USDA

Life cycle

Clematis 'Broughton Star' starts its life cycle as a seed, but it is often propagated through cuttings or layering to ensure the cultivar's characteristics are conserved. The plant then enters a vegetative stage where it produces stems and leaves; in this stage, it needs support as it is a climbing vine. With appropriate care, including adequate sunlight, water, and soil nutrients, it reaches maturity and begins to flower, often in late spring to early summer. The flowers are the reproductive part of the plant, displaying a double-flowered form that is pink and magenta in color. Following pollination, which can be facilitated by insects or wind, the flowers develop into seed heads that release seeds, completing the reproductive cycle. During winter or in unfavorable conditions, the Clematis 'Broughton Star' goes into dormancy, with the above-ground growth dying back and the plant surviving on stored energy in its root system until favorable conditions return.

Propogation

• Propogation time

  Spring-Early Summer

• Propogation: The Clematis 'Broughton Star', often referred to as Montanas Clematis, is typically propagated through semi-hardwood cuttings. The most optimal time for taking cuttings is during late summer or early fall. To propagate through semi-hardwood cuttings, select a healthy stem that is not yet woody but has matured enough that it's no longer soft or green. Cut a 4 to 6 inch (10 to 15 cm) length of stem just below a leaf node. Remove the lower leaves, dip the cut end in rooting hormone to encourage root growth, then plant the cutting in a moist potting mix. Ensure the soil remains damp but not waterlogged, and place the cutting in a warm, shaded area until roots develop, which typically takes several weeks. Semi-hardwood cuttings allow the plant to establish roots before a dormant winter season and be prepared for spring growth.
