This fine Amaryllid has to be seen in full bloom to be appreciated. It bears several spikes, each of which is surmounted by a large umbel of pure white funnel-shaped flowers. These, when backed up with its beautiful foliage, make it a noble and attractive plant. Of all the pancratiums I consider this one of the finest. It requires a stove or warm greenhouse to grow it to perfection. I find the following treatment to suit it perfectly: They are increased from offsets that push up from he base of the flowering bulb, and which, if severed from the bulb that produces them, with the roots which they have made entire, will at once commence to grow.
To thus increase them, it is necessary to turn them out of the pots and shake the soil away, so as to separate them without injury to the roots. But this is an operation which should not be resorted to often, as they do not like being disturbed at the roots, and offsets increase faster by being left on the parent plant till there are several of them to take off. As they do not like to be meddled with in a growing state, the operation should be performed when they are at rest. The young stock thus removed should be potted in small pots, the size of which will be regulated by the size of the bulbs; on no account should they be over-potted, as, if too much room be given them, they will never do well, and the soil is apt to sour. Therefore, the principal thing to avoid in cultivating this class of plants is over-potting. The best soil to use, is a good loam, well incorporated, with a little sand and rotten cow manure. In potting, disperse the roots evenly in the pot, keeping about two-thirds of the bulb above the soil, which should be rammed well with the potting lath, to make it quite solid. They should have plenty of light.
Be careful not to over-water them until the roots begin to grow freely, after which they must have as much as will keep the soil moderately moist until after their growth is made. If the plants are small, it is better to keep them growing for the first season, the idea being to get them as large as possible. When they fill a 7-inch or 8-inch pot well with roots, then they can be treated for flowering, which should be done by giving them a good rest, say for four or five months. If you want them to bloom about Christmas time, let them rest during the summer months, giving them as much water as will keep them from getting dust dry. As this pancratium belongs to the evergreen section, it should never be allowed to get too dry, or will suffer. About the first of November the pots should be examined, to see if the drainage is all right, or if they need a shift into a larger pot. Now is the time to do it, but remember they must not have too much pot room, or your flowers will be scarce. You can have them in flower at any time of the year, according as you regulate their resting period, but I should think winter preferable to have them in bloom, as any one who can boast of a garden and greenhouse has plenty of flowers out of doors in the summer.
They are not much subject to insect pests, although green-fly, thrips, and scale will live upon them if not taken good care of. A liberal use of the syringe and tobacco smoke will exterminate the former, and the latter can be removed with the sponge.
