lupin 'The Chatelaine'


Lupinus 'The Chatelaine', also known as The Chatelaine Lupine, is a captivating perennial known for its ornamental features. This plant boasts tall spires adorned with densely packed, sweetly scented flowers that have a graceful bicolor appearance—generally a soft pink with a white standard, which is the upright petal in the flower's center that can sometimes display a gentle flush of another color. The flowers are arranged in a whorled pattern around the spike, contributing to a striking vertical element in the garden landscape. The foliage of The Chatelaine Lupine is palmately compound, meaning the leaves radiate out from a central point like the fingers of a hand. Each leaflet is narrow with a pointed tip, adding a delicate texture to the plant that contrasts beautifully with the robust flower spikes. The leaves are a rich green color that further highlights the pastel hues of the blooms. This plant, with its impressive flower display and attractive foliage, creates a dramatic visual impact. It's particularly popular for its period of bloom in late spring to early summer, when the garden is transformed by the vertical interest and romantic color palette of The Chatelaine Lupine.

As needed
  • water dropWater

    The Lupine, commonly known as 'The Chatelaine', should be watered deeply and thoroughly to ensure water reaches the root zone, about once a week during its active growing season in spring and summer. It's vital to allow the soil to dry out slightly between waterings, but not completely, which helps prevent root rot. Depending on the climate and soil drainage, you may need to adjust watering frequency. On average, providing roughly one to two gallons of water per week should suffice, though this can vary depending on weather conditions.

  • sunLight

    Lupines, such as 'The Chatelaine', thrive in full sun to partial shade. They perform their best when receiving at least 6 hours of sunlight a day, so placing them in a spot where they can soak up the morning sun with some afternoon shade is ideal. Avoid deep shade as this can hinder flowering and promote fungal growth.

  • thermometerTemperature

    Lupines like 'The Chatelaine' prefer moderate temperatures, thriving best when daytime temperatures are between 60 to 75 degrees Fahrenheit. They can tolerate a minimum temperature down to freezing (32 degrees Fahrenheit) and a maximum temperature of about 85 degrees Fahrenheit, but prolonged exposure outside this range can stress the plant.

  • scissorsPruning

    Prune the Lupine, 'The Chatelaine', to encourage bushy growth and to remove spent floral spikes to potentially stimulate a second bloom. Prune after the first flowering, usually in midsummer, and deadhead as necessary. Cutting back the plant by about one third can also help revitalize leggy specimens.

  • broomCleaning

    As needed

  • bambooSoil

    Lupine 'The Chatelaine' thrives in light, well-draining soil with a slightly acidic to neutral pH range of 6.0 to 7.0. A high-quality soil mix that includes compost, peat, and sandy or gritty materials to improve drainage is ideal. Regular feeding with a balanced fertilizer will support robust growth.

  • plantRepotting

    Lupines, such as 'The Chatelaine', are typically perennial plants and do not require frequent repotting. They are often grown as annuals; hence repotting is usually not necessary. If planted in containers, repotting every couple of years may be needed to refresh the soil.

  • circleLife cycle

    Lupinus 'The Chatelaine' (also known as Lupine), belonging to the Band of Nobles Series, begins its life cycle as a seed that germinates in early spring once the soil has warmed and danger of frost has passed. After sprouting, the seedling grows rapidly, sporting its characteristic palmate leaves, and strengthens its root system. The plant then enters a vigorous vegetative stage, during which it develops a sturdy stem and foliage. By late spring to early summer, the Lupine progresses to the flowering stage, where it produces tall, colorful spires of pea-like flowers that attract pollinators. Following pollination, seeds develop in pods and, once mature, the pods crack open to disperse seeds for the next generation. The lupine is a perennial, so after seeding, it may die back in fall or winter, depending on climate, to re-emerge from its rootstock the following spring.

      Spring-Early Summer

    • Lupine 'The Chatelaine', a member of the Band of Nobles Series, can be propagated through a popular method which involves sowing seeds directly. The best time to propagate lupines by seed is in spring. Seeds should be sown in a light, well-draining soil mix, with a light covering of soil. Prior to sowing, it's recommended to soak the seeds in lukewarm water for a period of 24 hours to soften the seed coat and promote germination. Sow the seeds about 1/8 inch deep (approximately 3 millimeters) and keep the soil consistently moist but not waterlogged. Seedlings typically emerge in 14-28 days, depending on soil and weather conditions. Once the seedlings have grown strong enough to handle, they can be transplanted to their final growing position, ensuring they are spaced adequately to accommodate their mature size.
