Lupins 'Blue Sonet' is a hardy annual green manure that can be planted from March to July and is part of the legume family. They suit light sandy acid soils and soils up to pH8 and are a hardworking leguminous plant that has very long tap roots that dredge up minerals. Lupins fix 25% more free nitrogen than clovers and 28% more than peas and beans. The long roots also help to break up and aerate heavier soils and allow more moisture retention with the addition of humus from the break down of the roots on light sandy soils.
Lupin Blue Sonet produce a beautiful blue flower but it is best to dig it in and cut down before they flower to help prevent them seeding and then becoming a nuisance. The flowers are great for insects so a few could be left to flower to draw more insects into the vegetable area.
It is possible to sow Lupins as an intercrop, e.g. among long growing varieties of veg like cabbage and sprouts, where they will contribute nitrogen to the soil (once they are dug in) and help promote growth in the veg crop. Treat as a legume for crop rotation purposes so great before nitrogen hungry crops like brassicas. Lupins can be slower to germinate than other green manures.
Did You Know?
That Lupins (Lupinus angustifolius) is a high-protein crop... the beautiful flowers are followed by large pods full of nutritious seed like a flattened bean. The kernels of Lupin are rich in protein (40%), fibre (40%) and moderate in fat (8%) made up largely of unsaturated fatty acids.
They are popular in Italy, often salted and served with a cold glass of beer!
COOKING: With young tender lupin seeds (in the green pod stage) you can just shell them out and boil them for 15 minutes or until soft. If cooking with dried lupin seeds then you will need to soak them overnight, then boil in fresh water for 40 minutes or until tender.
People who are allergic to peanuts can also react to eating lupin seed, so don't feed lupins to anyone with a peanut allergy.
Plant your Lupin seeds in spring (April onwards) in a small pot and transplant them out once about 4 or 5 inches tall. Maybe plant two seeds per pot as germination is often a bit erratic.
