Lupine Lupinus 'Blossom' (PBR)

Water

Lupine 'Blossom' prefers evenly moist soil, particularly during the growing season. Water these plants deeply once a week, providing about 1 inch of water each time, which equates to roughly 0.6 gallons per square yard of soil. During hot, dry periods, additional watering may be necessary to maintain moisture, but always allow the soil to dry out slightly between watering sessions to avoid waterlogging, which can lead to root rot. It's best to water lupines early in the morning to reduce evaporation and allow the foliage to dry out during the day, reducing the risk of fungal diseases.

Light

Lupine 'Blossom' thrives in full sun to light shade. The ideal location for these plants is a spot that receives at least 6 hours of sunlight daily, which encourages strong growth and vibrant blooms. Although they can tolerate some light shade, too much shade can lead to weak, leggy plants with fewer flowers. If you're planting in a particularly hot climate, some afternoon shade can prevent scorching.

Temperature

Lupine 'Blossom' is hardy in USDA zones 4 through 8 and can tolerate temperatures as low as 20 degrees Fahrenheit and as high as 75 to 80 degrees Fahrenheit. However, they flourish in cooler temperatures ranging from 60 to 70 degrees Fahrenheit. Extreme heat can stress the plants, especially if night temperatures remain high.

Pruning

Prune Lupine 'Blossom' plants to encourage bushiness and the production of secondary flowers. Deadhead spent blooms by cutting back the flower spikes to the base or to a set of leaves to promote a second bloom. The best time for pruning is immediately after the initial flowers fade, which is usually by mid-summer. If the foliage looks ragged or mildewed in late summer, it can be cut back to the ground to encourage fresh growth.

Cleaning

As needed

Soil

Lupine 'Blossom' thrives in light, well-draining soil with a slightly acidic to neutral pH between 6.0 and 7.0. A mixture of loam, peat, and sand is ideal to provide the necessary drainage and aeration. Enriching the soil with organic matter can also encourage healthy growth.

Repotting

Lupines, including the 'Blossom' variety, typically do not need to be repotted often as they are perennial plants. They should be repotted only if the plant has outgrown its current container or if the soil has become compacted and needs refreshing, which is usually every 2-3 years.

Humidity & Misting

Lupine 'Blossom' prefers moderate humidity levels but is quite adaptable and can tolerate the humidity levels typically found in most outdoor environments. There is no need for specific humidity control for this plant.

Suitable locations

• Indoor

  Place in bright light, ensure good air flow, and water deeply.

• Outdoor

  Choose sunny spot, protect from strong winds, water well.

• Hardiness zone

  4-8 USDA

Life cycle

The life of Lupine 'Blossom', also known as simply Lupine, begins with seed germination, usually occurring in spring when soil temperatures warm. Following germination, the seedling stage commences where the plant develops its first true leaves and establishes a root system. As the plant matures during the vegetative stage, it develops a robust foliage structure and elongated stems in preparation for flowering. The reproductive stage follows, where vibrant spikes of flowers bloom, attracting pollinators which facilitate cross-pollination. After pollination, the plant produces pods containing seeds that mature and are eventually released into the soil to perpetuate the cycle. During the senescence phase, typically in late summer or autumn, the lupine plant will die back, especially in colder climates, though it may act as a perennial in warmer zones, where parts of the plant go dormant before regenerating the following spring.

Propogation

• Propogation time

  Spring-Early Summer

• Lupinus 'Blossom', commonly known as the Lupine, is a popular herbaceous perennial that is normally propagated by seed. The best time to sow Lupine seeds is in late winter or early spring, ensuring they get plenty of cold stratification, which assists in breaking seed dormancy. To propagate by seed, prepare a seed starting mix and plant the seeds at a depth of approximately an eighth of an inch (about 3 millimeters). Water them in well and keep the soil moist. Seeds should germinate within 14 to 21 days with sufficient light and temperatures between 55-70 degrees Fahrenheit (12-21 degrees Celsius). Once the seedlings develop true leaves and are sturdy enough, they can be transplanted into individual pots or directly into the garden, spacing them 12-18 inches (30-46 centimeters) apart. It is important to note that Lupines prefer well-draining soil and full to partial sun to flourish.
