The soil should be allowed to dry out between waterings; however, don't let it become completely dry. Adjust the amount of water during rainy seasons to avoid overwatering, which can lead to root rot. When watering, direct the water at the base of the plant rather than overhead to minimize the risk of mildew and other fungal diseases.

  • sunLight

    Desert Sun Lupine thrives in full sunlight, requiring at least 6 hours of direct sun daily. The plant's ideal spot is in an area that receives uninterrupted sunlight throughout the day. Avoid planting in shaded areas, as insufficient light may hinder bloom production and affect the plant's overall health.

  • circleLife cycle

    Lupine 'Desert Sun' starts its life as a seed that, when sown and given the proper conditions, will germinate and produce a small seedling. The seedling will grow into a juvenile plant, developing a strong root system and foliage, before entering the vegetative stage where it focuses on leaf growth. As it matures, it progresses to the flowering stage, where it develops distinctive colorful spires of flowers, typical of Lupines, which are attractive to pollinators. After pollination, the flowers will produce pods containing seeds, thus completing the reproductive stage. Once the seeds are mature, they are dispersed from the parent plant, and this perennial plant may enter a period of dormancy, especially in colder climates, before starting the cycle anew in the next growing season. Over several years, Lupine 'Desert Sun' will reach maturity, with its life span typically ranging from a few years to several years depending on growing conditions and care.

    • Propogation time

      Spring-Early Summer

    • Propogation: The Lupine 'Desert Sun', a stunning perennial known for its vibrant colors, can be propagated primarily through seed sowing. The best time to sow Lupine seeds is in spring, around April to May, when the danger of frost has passed and the soil has begun to warm up. To propagate, soak the seeds in water for a period of 24 hours to soften the tough outer shell, which will foster germination. After soaking, sow the seeds about 1/8 inch (approximately 3 millimeters) deep in a well-draining soil mix. Ensure the soil remains moist but not waterlogged as the seeds germinate, which usually takes a few weeks. Once the seedlings have developed a couple of true leaves, they can be transplanted to their final location in the garden, spacing them about 12 to 18 inches (around 30 to 46 centimeters) apart to allow for mature growth. It's important to note that with patented plant varieties like Lupinus 'Desert Sun' (PBR), reproduction through seeds or any other method may be legally restricted due to plant breeders' rights.
