 Lupinus : Lupinus Arboreus, the tree-Lupin, is quite 

 different from the ordinary border varieties. It develops 

 into a huge bush if given a sunny and sheltered position, 

 and this bush is covered from June-September with yellow 

 or white flowers. Tree Lupins do best on very hungry 

 soils. They thrive excellently on the red sand capping 

 the Oxford Clay in Berkshire. They need no care except 

 frequent hoeing and strong staking, and are not thirsty 

 plants. They may be raised from seed ; or they may be 

 propagated by division, which, however, is not at all easy, 

 as may be seen by examining the roots of a plant in the 

 autumn. 



The border Lupin, L. polyphyllus, is hardier, and while 

 not such a good drought resister as the tree-lupin it is not 

 a particularly thirsty plant. It often grows to 3-5 ft. high, 

 and the spikes themselves are frequently 24 ins. in length. 

 It enjoys a position in a sunny border, and may be planted 

 near shrubberies where it need not be disturbed. It will 

 grow nearly everywhere, and therefore is specially suitable 

 for town gardens. It should not be replanted frequently, 

 and like the tree-lupin it is almost impossible to divide the 

 roots. It is best to raise it from seed sown in May or June, 

 and to discard the old roots when they get too big. Stake 

 securely in mid-May.
