Lupinus Polyphyllus Albus.
There are blue and white Lupins, and both kinds flower at the same time and require the same treatment. We advise you to choose the white one if you have blue Delphiniums, as they will come out together, and make your garden gay all through June. Slugs are very fond of Lupins, and you often find a fine spike just about to flower half eaten away. Unless you want to increase your stock from seed, you should cut off the flowers as they fade, in order to prolong the flowering season. The plants may be left undisturbed year after year, and will make large clumps that grow from three to six feet high. If you take up a Lupin you will find it has huge tap-roots, and on this account it is not an easy plant to transplant or divide. When you want to move them, you must do it in the autumn, after the leaves have died down. The seeds come up easily if you sow them in a box, and the seedlings flower the second year; but if you have blue and white Lupins, the seed from your white Lupin will produce many washed-out blue flowers.
