  • water dropWater

    Lupine 'Polar Princess' requires consistent moisture, especially during the growing season. Water the plant thoroughly once a week, providing about 1-2 gallons per watering, ensuring the soil is moist but not waterlogged. During hot and dry spells, increase watering frequency to maintain moisture levels. In cooler and wetter periods, reduce watering to prevent root rot. It's important not to let the soil dry out completely between waterings.

  • sunLight

    The lupine 'Polar Princess' thrives best in full sunlight. They need at least 6 hours of direct sunlight daily to ensure vigorous growth and abundant flowering. The ideal spot for planting would be in an area that receives unobstructed sunlight for most of the day.

  • thermometerTemperature

    Lupine 'Polar Princess' prefers temperate climatic conditions and does well in temperatures ranging from 60 to 70 degrees Fahrenheit. The plant can survive minimum temperatures down to 20 degrees Fahrenheit but will not tolerate prolonged periods of extreme cold or heat. The ideal temperature range promotes healthy foliage and flowering.

  • scissorsPruning

    Prune the lupine 'Polar Princess' to encourage bushier growth and to remove spent flower spikes, which promotes further blooming. Pruning should be done immediately after the initial flowering finishes, typically in mid to late summer. Removing faded flowers before they set seed also prevents unwanted self-seeding.

  • circleLife cycle

    The Lupinus 'Polar Princess', commonly known as Polar Princess Lupine, begins its life cycle as a seed, which upon germination in the spring, roots in the soil and sprouts a small rosette of leaves. The plant rapidly enters a vegetative stage where it develops a strong stem and a larger rosette of distinct palmate leaves. Following the vegetative growth, the Polar Princess Lupine enters the flowering stage usually in late spring to early summer, producing tall, erect spikes adorned with white flowers that are attractive to bees and butterflies. After pollination, these flowers turn into seed pods that ripen, dry, and eventually split open to release seeds for dispersal. The plant can then go into a period of dormancy, especially in colder regions, where it may die back to the ground and conserve energy in the roots until the following spring. The life cycle is completed when new growth emerges from the perennial rootstock, repeating the cycle.

      Spring-Early Summer

    • The Lupinus 'Polar Princess', commonly known as Lupine, can be propagated by seed. The most popular method is to sow the seeds directly into the ground or into pots. For best results, seeds should be sown in the spring or autumn. To propagate Lupine by seed, one should first scarify the seeds by gently rubbing them with sandpaper to break the seed coat, which enhances water absorption and germination. After scarification, the seeds should be soaked in water for a period of 24 hours to further assist in softening the seed coat. Once prepared, the seeds can be planted about 1/8 inch (approximately 3 mm) deep in well-drained soil and kept moist until germination, which typically occurs within two to four weeks. Once seedlings appear, they should be thinned out or transplanted to allow ample room for growth.
