  • water dropWater

    Cupflower plants are best watered deeply and then allowed to dry out slightly between waterings. Generally, this means watering about once a week but adjust the frequency depending on weather conditions and soil drainage. Each watering should be thorough, providing about 1-2 gallons of water per plant, ensuring moisture reaches the roots. To avoid fungal diseases, water at the base of the plant to keep foliage dry. During hot spells or in particularly dry regions, check the soil moisture more frequently as additional watering may be necessary.

  • sunLight

    Cupflower plants thrive in full sun to partial shade. They perform best when they get at least 6 hours of direct sunlight a day. Ideal placement is in an area where they are exposed to morning sun and some afternoon shade, particularly in hotter climates. Avoid deep shade conditions as this can impact the plant's flowering and overall vigor.

  • thermometerTemperature

    Cupflower plants prefer moderate temperatures and are hardy in a range from about 30°F to 90°F. They can survive light frosts but prolonged exposure to temperatures below freezing can damage or kill the plant. Ideal growing conditions are between 60°F and 70°F. Providing protection from extreme cold or excessive heat will benefit the plant's growth and blooming.

  • scissorsPruning

    Pruning Cupflower plants helps to encourage bushier growth and more blooms. Lightly prune or pinch back the tips of the plants after the initial flush of flowers to promote a second blooming. This can be done every few weeks during the growing season. The best time for more significant pruning is early spring or after the plant has finished flowering, to tidy up the shape and remove any spent blooms or damaged stems.

  • circleLife cycle

    The Nierembergia scoparia 'Mont Blanc', commonly known as Cupflower, begins its life cycle as a seed, which when sown in warm soil typically during spring will germinate within a few weeks. After germination, the seedling emerges and starts developing its root system and foliage in a rosette pattern. As the plant matures, it enters a vegetative stage characterized by the growth of stems and leaves, and it forms a bushy, low mound. Further into the growing season, usually in late spring to early summer, the Cupflower starts to produce its characteristic white, trumpet-shaped flowers that continue to bloom throughout the summer until fall. After the flowering stage, if the pollinated flowers set seed, the plant enters a reproductive stage where it produces seed capsules that mature and eventually release seeds for the next generation. Finally, as an herbaceous perennial in suitable climates, the Cupflower will die back to the ground with the onset of winter's cold, to reemerge from its rootstock once the weather warms again in spring.

    • Propogation time

      Spring to Summer

    • Propogation: The most popular method of propagating Nierembergia scoparia 'Mont Blanc', also known as Cupflower, is via seed. Propagation time often begins in late winter to early spring, as this allows for ample growth time before planting out after the frost. Seeds can be sown in seed trays or pots filled with well-draining soil mix. They should be lightly covered with soil and kept consistently moist but not waterlogged. To encourage germination, maintain a temperature of around 70 degrees Fahrenheit (21 degrees Celsius). Seedlings usually appear in 14 to 21 days, after which they can eventually be transplanted to individual pots when they are large enough to handle and eventually moved outdoors when the risk of frost has passed.
