Please donate to support our ‘Plants to Save the Planet’ Project. The Project is directed at enabling designers of ‘carbon farms’ and ‘food forests’: agroecosystems of perennial plants, to choose the most appropriate plants for their requirements and site conditions. We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs. We are adding search terms and icons to those plants pages, and providing a range of search options aligned to categories of plants and crop yields, with Help facilities including videos. More >>>

Lupinus perennis - L.

Common Name Sundial Lupine
Family Fabaceae or Leguminosae
USDA hardiness 4-8
Known Hazards The seed of many lupin species contain bitter-tasting toxic alkaloids, though there are often sweet varieties within that species that are completely wholesome[65, 76]. Taste is a very clear indicator. These toxic alkaloids can be leeched out of the seed by soaking it overnight and discarding the soak water. It may also be necessary to change the water once during cooking. Fungal toxins also readily invade the crushed seed and can cause chronic illness[65].
Habitats Grassy places in dry sandy soils[187].
Range Eastern N. America - Maine and Ontario, west to Minnesota and south to Florida.

Edible Uses

Edible Parts: Seed  Seedpod
Edible Uses:

Seed - cooked[105]. Used as a protein-rich vegetable or savoury dish in any of the ways that cooked beans are used, they can also be roasted or ground into a powder. The seed has a bitter flavour due to the presence of toxic alkaloids, it should be thoroughly leached before being cooked[2, 105]. Seedpods - cooked[105].

Medicinal Uses

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
Antiemetic  Haemostatic

A cold tea made from the leaves has been used to treat nausea and internal haemorrhages[222, 257].

Our new book Edible Shrubs is now available.

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Cultivation details

An easily grown plant, succeeding in any moderately good soil in a sunny position[200]. Grows well in a poor sandy soil[187]. Requires an acid to neutral soil[200]. Plants are hardy to about -25°c[187]. This species is very susceptible to slug damage. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[200]. The plant is heat tolerant in zones 9 through 1. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a clumper with limited spread [1-2]. The root pattern is flat with shallow roots forming a plate near the soil surface [1-2].

Propagation

Pre-soak the seed for 24 hours in warm water and then sow in early spring in a greenhouse. Germination should take place within a couple of weeks. When they are large enough to handle, prick the seedlings out into individual pots and plant them out in early summer. It should also be possible to sow the seed outdoors in situ in the middle of spring. It might be necessary to protect this sowing from mice. Division in early March[1]. Difficult. Basal cuttings in April[1]. Harvest the shoots when they are about 10cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer.

If permitted, this plant thrives in northern Maine (hardiness zone 3b). Appears in unmowed pastures of abandoned farms. pH 5.5 to 6. Organic matter 6 to 7%. Caribou gravelly loam, annual rainfall 34 inches. Obviously, this wild plant can be grown organically. Interesting you mention potential mice damage. A red fox and occasional hawk patrol my 4-acre field regularly.

This plant was introduced in a western U.S. national park and now they would like to eradicate it. I need some advice on how to eradicate Sun Dial Lupine
