It is propagated by offsets, which are often planted in September or October, but the principal crop should not be got in earlier than February or the beginning of March.
Attached to the rod by offsets are one or more plunger or bucket pumps, set at intervals in the shaft.
Babylonica is sometimes spoken of as Pope's willow, having been cultivated by that poet, or as Napoleon's willow, because his tomb at St Helena is overshadowed by a tree of this species, from which many offsets exist or are reputed to exist in modern gardens.
They are readily propagated by offsets or by seed.
Are called the offsets from the diagonal to the angular points.
Along the base-line, and the lengths and directions of the offsets NB, PC, QD,.
The breeder bulbs and their offsets may grow on for years producing only self-coloured flowers, but after a time, which is varied and indefinite, some of the progeny "break," that is, produce flowers with the variegation which is so much prized.
Tulips are usually increased by offsets, which most varieties produce in fairly large numbers.
Some varieties produce offsets sparingly and must be increased by seed - a slow and uncertain method.
They are then lifted and treated like offsets, being sown thinly in beds out of doors.
Running south-west to north-east, and united on the north with one of the offsets of the Pyrenees, is the range of the Sierra Llena, which bisects Catalonia, and forms its central watershed.
Proliferum, produces small bulbs instead of flowers, and a few offsets also underground.
The stem bulbs of lilies are similar in character to the offsets from the parent bulb.
After they have ripened in connexion with the parent bulb, the offsets are taken off, stored in appropriate places, and at the proper season planted out in nursery beds.
Neat-growing, succulent plants, forming rosettes of fleshy leaves close to the ground, and rapidly increasing by runner-like offsets; they are well adapted for rockwork, and do best in sandy soil.
The head is pruned to form six or eight strong offsets; and by judicious use of the knife, and by training, preferably on a hoop placed within them, these are caused to grow outwards and upwards to a height of about 6 ft.
Like other bulbs they are increased by offsets, which should be carefully removed when the plants are at rest, and should be allowed to attain a fair size before removal.
They mature very slowly and die after flowering, but are easily propagated by the offsets from the base of the stem.
(4) The columella, a structure which occupies the centre of the calicle, and may arise from the basal plate, when it is called essential, or may be formed by union of trabecular offsets of the septa, when it is called unessential.
