Menopause, or the cessation of menstrual periods, generally occurs in the 40s and 50s and marks the cessation of fertility, although age-related infertility can occur before then.
Silky lupine grows in northern areas from Washington and Oregon east to South Dakota. Tailcup lupine is found in Oregon, California, Idaho, Utah, Montana, and Wyoming. Velvet lupine is found in an intermountain region from Oregon to Wyoming. Silvery lupine occurs from North Dakota and Idaho south to Arizona and New Mexico.
Lupines need neutral to slightly acidic soil, although they can grow in very acidic soil conditions. Lupines donât need rich loam, but itâs important to grow the plants in very well-draining soil to avoid root rot. Sandy soil conditions and poor rocky soil promote the growth of the lupineâs deep tap root. Starting lupines from seed is an economical way to get a showy flower garden the following season. The seed coat is tough, and seeds have a better germination rate if you nick the seed coat or soak them in water overnight.
