Lupin Blue Giant Seeds for Non-GMO Perennial Garden Planting

The perennial plant known as lupine is characterized by hollow, powerful stems that can reach a height of 30-50 inches. It features beautiful large spike-like inflorescences in shades of blue. To grow lupine, start by soaking the seeds in warm water overnight to enhance germination. Plant the seeds in loose, compost-amended soil with a spacing of 12 inches between each seed. Once the seedlings have germinated, thin them out to a spacing of 2 to 3 feet apart.

If you prefer nursery-grown plants, they are usually perennials and can be planted in spring or summer, following the same spacing guidelines. To achieve a better visual effect, group the plants together. Lupines thrive in cool soil and temperatures. Therefore, if you are growing them in a southern region, it is best to choose a location that offers afternoon shade to help the plants survive the heat of summer. Additionally, lightly mulch the plants in hot climates to keep the soil cool and moist.

Lupines are drought-tolerant and generally do not require extra watering once established. In terms of fertilization, apply a layer of compost in spring. These plants have taproots that fix nitrogen, so they do not need much additional fertilizer. They also help improve the growth of surrounding plants by breaking up heavy soils.

To encourage more blooms, deadhead spent flowers immediately after they have bloomed. This practice can lead to side shoots that will flower again later in the summer. In the fall, when the foliage starts to yellow, cut back the entire plant to the ground.

If you want to promote self-sowing, leave some of the flowers to set seed. Lupines do not divide well and primarily spread through seed propagation. The package includes approximately 30 seeds, and English instructions are provided. Lupines are of interest in the spring, summer, and autumn seasons. They thrive in USDA hardiness zones 4-9. The specific species is Lupinus polyphyllus, and the germination rate is 90-95%.
