Soil: Lupine needs well-draining soil above all else. It prefers soil on the acid side and will not tolerate high levels of alkalinity or water-logged conditions. Russell hybrids and L. polyphyllus have more tolerance for moist conditions than many other species, but none are lovers Read more
Lupine flowers may be annual and last only for a season, or perennial, returning for a few years in the same spot in which they were planted. The lupine plant grows from a long taproot and does not like to be moved.
In a nutshell, it is an invasive plant that can crowd native species out of their preferred habitats. Also, their seeds are toxic to animals if too many are consumed, which could threaten both grazing farm animals and native herbivores. This does not mean that Read more
Lupinosis is a liver diease caused by mycotoxins (phomopsins) produced by a fungus growing on the pods or seeds. Since lupines are most toxic in early growth and when seed pods are present, cattle should be kept from grazing the plants at these stages.
Growing to be about 12-36” tall, Lupine is a great choice for the front of the meadow or garden bed. Extremely easy to grow and deer resistant, this perennial flower blooms year after year.
The best time to plant untreated lupine seeds outdoors is between September-November. Plants grown from seed will bloom their first year. Pinch off spent flowers to prolong the blooming period.
Light: Full sun is preferred. Lupine can grow in part shade, but flowering will be lessened. Soil: Lupine needs well-draining soil above all else.
Lupines contain alkaloids that are known to be toxic to humans and animals. Though toxicity has been predominantly noted in livestock, the danger of poisoning in dogs is a possibility.

Lupines are deep rooted and do not spread except through re-seeding. Seeds will not come true to the original variety planted, but will eventually revert to blue-violet and white.
Choose a sunny site with average, well-draining soil. Lupines are legumes and can improve a soil's fertility over time. Light: Full sun is preferred. Lupine can grow in part shade, but flowering will be lessened.
