  • skullToxicity

    • To humans

      Lupins, including the variety 'Masterpiece', contain toxic alkaloids, primarily in the seeds, that can cause poisoning if ingested. Symptoms of lupin poisoning can include digestive upset such as nausea, vomiting, abdominal pain, and diarrhea. More severe reactions may involve tremors, dizziness, and respiratory issues. Ingesting lupin seeds can lead to alkaloid toxicity, which can have serious health consequences, and medical attention should be sought if poisoning is suspected.

    • To pets

      Lupins, including the 'Masterpiece' variety, are toxic to pets and can cause similar symptoms as in humans if ingested. The alkaloids present in the plant can lead to poisoning, resulting in gastrointestinal upset, such as vomiting and diarrhea, and more severe cases can cause nervous system signs, like tremors or seizures. If a pet ingests lupins, it is important to contact a veterinarian promptly, as the toxicity can have serious and potentially life-threatening consequences.

  • water dropWater

    The Lupine requires regular watering, especially during the growing season. Water at the base of the plant, avoiding overhead watering to prevent leaf diseases. Initially, water the plant once or twice a week, providing it with about 1 inch of water each time. As the Lupine establishes itself and matures, it can be watered less frequently; however, during hot, dry spells, increase watering to ensure the soil remains moist but not waterlogged. During winter months, reduce watering significantly, but don't allow the soil to completely dry out.

  • sunLight

    Lupines thrive in full sunlight, requiring a minimum of 6 hours of direct sunlight daily to flourish. Place them in a location where they receive plenty of morning light and, if possible, some afternoon shade in areas with very hot summers. Avoid deep shade, as this will reduce blooming and can encourage fungal diseases due to lack of proper sun exposure.

  • thermometerTemperature

    Lupines prefer cooler temperatures and will thrive in conditions between 60 to 75 degrees Fahrenheit. They can survive minimum temperatures down to about 20 degrees Fahrenheit, but extended periods below freezing can damage or kill the plant. The ideal temperature range for robust growth and flower production is between 60 and 70 degrees Fahrenheit.

  • scissorsPruning

    Prune Lupines to encourage repeat blooming and to maintain plant health. Deadhead spent flower spikes after the first bloom has finished to stimulate a second blooming cycle. At the end of the growing season, cut the foliage back to the ground to promote healthy growth in the spring. The best time for pruning is immediately after the first flowering ends and again in late fall or early winter.

    The Masterpiece Lupin thrives in slightly acidic to neutral soil, with an optimal pH range of 6.0 to 7.0. A well-draining soil mix comprising of garden loam, peat, and sharp sand is ideal. Ensure the soil is rich in organic matter to promote vigorous growth and flowering.

  • plantRepotting

    Lupins, including the Masterpiece Lupin, generally do not need frequent repotting and can be left undisturbed for several years. They may only require repotting if they outgrow their current container or if the soil needs replenishment, typically every 2-3 years.

  • water dropsHumidity & Misting

    Masterpiece Lupins prefer moderate humidity levels but are quite adaptable and can tolerate the humidity found in most garden environments. They do not require any special humidity considerations, making them suitable for a typical outdoor setting.

  • circleLife cycle

    Lupinus 'Masterpiece', commonly known as Masterpiece Lupine, begins its life as a seed which, when sown in well-drained soil and exposed to the cool temperatures of early spring or fall, will germinate and sprout. The seedling stage is characterized by the appearance of the plant's first true leaves after the initial cotyledons, establishing a root system and beginning photosynthesis. As the plant enters the vegetative stage, it rapidly produces more leaves, establishing a rosette, and stores energy in preparation for flowering. The reproductive stage occurs when the plant sends up a flowering spike, typically in late spring or early summer, showcasing tall, vibrant, and colorful spires of pea-like flowers that attract pollinators. After pollination, the lupine sets seed pods, which mature, dry, and eventually release seeds, thus completing the cycle. In cold climates, lupines are perennial, dying back to the ground in winter and regrowing from the rootstock the following spring, whereas, in warmer regions, they may complete their life cycle within a year.

      Spring-Early Summer

    • Commonly known as Lupine, Lupinus 'Masterpiece' (PBR) is often propagated by seed. The ideal time to sow seeds is in late winter or early spring, as this coincides with the natural germination period for many perennial plants. To propagate Lupine by seed, you first need to scarify the seeds, which involves scratching or nicking the seed coats to improve water absorption. After scarification, the seeds are usually soaked in water for about 24 hours to further help break down the tough outer coating. The seeds are then sown in a well-draining soil mix, either in a greenhouse or under cloches if outdoor temperatures are not yet suitable. It's important to maintain a consistent moisture level after sowing but to avoid waterlogging, as Lupine seeds can rot in excessively wet soil. Seedlings usually emerge in 14 to 28 days, and after a few sets of true leaves develop, they can be transplanted to their final growing positions.
