What Is A Bigleaf Lupine Plant?
A big leafed lupine (Lupinus albus) is a member of the evergreen family of plants. They are native to North America, but have been introduced into other countries such as Australia and New Zealand. Larger than most trees, they grow up to 30 feet tall with a spread of several yards. Their leaves are long and narrow, reaching almost to their tips. These plants are found growing in dense forests, fields, woodlands and even urban areas.
Bigleaf lupines are not related to the common lupine (Lepidoptera: Nipponidae). They differ from them in having a broader crown and shorter branches.
They are native to the mountains of British Columbia, Canada.
How To Grow Bigleaf Lupine Seeds?
There are two ways to grow big leaf lupine seeds. One way is through seed starting and the other is through cuttings. Seed starting involves taking a small piece of your own foliage or cutting off a branch from another tree and planting it in soil containing the seeds. Cuttings take root in water and need light to develop properly.
Here are instructions for taking cuttings:
Choose a healthy branch with large healthy leaves, the bigger the better. Place it underwater and leave it there until it starts to grow roots.
This could take anywhere from a few days to a few weeks, depending on the size of the branch. Once you see roots form, remove it from the water and plant it in soil. After a few weeks in soil, you should see it start to flower.
Once you have a fully grown lupine, you need to take good care of it if you want it to flower. These plants need a lot of water in order to bloom. If they do not receive enough water, they will not bloom. You should also make sure they get at least six hours of sunlight and have rich soil to help them thrive. Make sure to give them a lot of water so the flowers can grow.
Lupine Flower Facts?
Bigleaf lupines have large beautiful flowers. There are over a hundred different species of big leaf lupines, all with different colored flowers and markings. The most common color is purple, but they can also be blue or pink. The markings can range from spots to stripes to polka dots. The size of the flower can be up to 10 inches across and their six petals each have a unique pattern on them.
The blooming period for bigleaf lupines is typically in late spring and sometimes early summer. They don’t usually last more than a week to ten days, so if you want to see them in all their glory you better keep an eye on the weather forecast.
The birth flower for March is the tulip.
Bigleaf lupines are a great addition to any garden and can be enjoyed by the whole family. If you ever get the chance to see them in person you should definitely take the time to do so.
Try planting a few in your own backyard and enjoy their blooming beauty every year.
