If starting indoors, scarify seeds by chipping, or soak in water for 24 hours prior to sowing. Keep the soil temperature cool by sowing shallowly, a couple of millimetres (1/8′′) deep. Seeds should be sown in late spring or early summer, when temperatures are warm enough for germination to take place.
Seedlings should not be transplanted until they have reached a height of 2-3 metres (6-10 feet) and a diameter of 1.5-2 cm (0.4-1.6 inches), depending on the type of seedling you are growing.

When should I start lupine seeds?
The seeds can be sown directly into a seedbed until august 1st. Between September-November is the best time to plant lupine seeds outdoors. Plants will bloom their first year after being grown from seed. To prolong the life of the plant, pinch off spent flowers. Lupines are hardy to USDA Zones 5-9.
Are lupines hard to grow from seed?
They are among the easiest perennials to grow from seeds. Perennial lupines grown from seed will not bloom until their second year. If you nick the seed coat or soak it in water before planting, the seeds will have a better chance of germinating. Lupine seedlings are easy to care for.
They can be kept in a pot or container in full sun or in partial shade. If you want to keep them indoors, you’ll need to water them once or twice a week. Keep the soil moist, but not soggy, and keep the temperature between 70 and 80 degrees F (21 and 25 degrees C). .
How deep should I plant lupine seeds?
When the soil can be worked, sow seeds in the early spring. When true leaves appear, be thin. The sun/part shade is the lightest point. Cuttings are easy to propagate from seed. Cut the seedlings into 2″ to 3″ sections and place them in a warm, well-drained pot. Water thoroughly and allow to dry completely before transplanting into the garden.
Should I soak lupine seeds before planting?
They have a very tough seed coat, and it’s a good idea to either soak seeds for 24-48 hours, or roughen them between two sheets of sandpaper before planting. Make sure the seeds make good contact with the soil by covering lightly with soil.
Plant the seedlings in a well-drained pot and allow them to grow for a few weeks before transplanting them into a larger pot. This will give them a chance to establish a root system before they need to be transplanted into the garden.
How long does it take for lupine to grow from seed?
Sprinkle water over the planting area after covering the seeds with a small amount of soil. The soil needs to be moist throughout the process. It takes 15 to 75 days for lupine sprout to show up in the soil. Lupines grow best in full sun to partial shade. They prefer well-drained soil with a pH of 6.5 to 7.0.
The soil should be moist but not soggy, and the plants should not be allowed to dry out during the first few weeks of growth. When the plant is about 2 inches tall, it is ready to be transplanted into the garden.
Do lupins grow back every year?
Lupins are perennial (i.e. they come up year after year) shrubs which start into growth after the last frosts, produce their first flush of flowers in late May / June and can continue flowering into early August / September. They can be found in a wide range of habitats, including woodland, hedgerows, parks, gardens, roadsides, fields and gardens.
Will lupines bloom the first year?
Perennials will bloom the first year after seeding, while annuals will bloom the first year after seeding. If growing from seed, soak the lupine seed in warm water before sowing. Seedlings should be transplanted into a well-drained potting mix and allowed to grow for a few weeks before transplanting to a larger pot.
This will give the seedlings a chance to establish a root system before they are planted in the ground. Once established, the plants will be able to tolerate a wide range of soil types and temperatures.
Can you direct sow lupine seeds?
If planting lupine from seed, direct sow in the garden in late fall or early winter for blooms the following spring. If you sow seeds in the spring 4 to 6 weeks before your average last frost date, your plants will bloom later.
Lupines are hardy to USDA Zones 5 through 9, and can be grown in USDA Zone 6 or Zone 7 gardens. They are drought tolerant and do well in full sun or partial shade.
Can lupine grow in pots?
Growing lupines in containers is a great option. You will need a larger container to grow them in. If you’re growing them indoors, you can use a pot that’s at least 10 inches in diameter. The amount of water you need depends on the size of your plant and the type of soil in which it’s growing.
For example, if you have a small plant that grows in a medium-sized pot, it will need about 1.5 to 2 gallons per day, depending on how much light you give it. On the other hand, plants that grow in larger pots will require more water than smaller plants, because they need more light and nutrients.
