PRETTY as a picture is this beautiful bulb, which is hardy south of Virginia, and variously known as hymenocallis, pancratium, Spanish Lily, Spider Lily, etc. It is one of the most desirable "novelties" I have grown for some seasons. Last spring 100 extra large bulbs were sent to me, many over the size of a pint cup, and after I had sold all I could, I planted the remnant late in May, and by August the plants were in full flower. I was astonished and delighted with the result. From August to hard frost the bulbs constantly bore great masses of fine, waxy white flowers, so fragrant that many objected to the odor as some object to that of tuberoses. They are also very peculiar in structure, each plant being furnished with one thick, strong stem, surmounted by clusters of blooms, often 25 to a stalk, which commence to open, a few each day, until the whole are expanded, the flowering period of one stalk being in this way extended from ten to fourteen days. Each bloom is single, with an expanded center much like a Morning Glory (convolvulus), but with long, slender, strap-like extensions or elongations from the outer edge, which is in five sections, and these give it an exceedingly quaint and attractive appearance.
From the parent stalk one can strip a single flower furnished with a stem and tube fully 5 to 8 inches long, so that it can be easily arranged for cut-flowers, giving an exquisite grace to any design. This Sea Daffodil is a native of the South, growing most readily in low, flat, undrained lands, but it readily adapts itself to any or all situations. Especially will it delight the amateur, as it can be potted, and with a little care, will flower in from two to six weeks. At the Centennial Exposition bulbs of this kind readily sold for $1. 50 apiece as Spanish Lilies, where the shrewd dealers kept a succession always in flower, which needed only to be seen to find eager purchasers. I would hesitate to say how many flowers my small bed, 4x18 feet, bore last season, but there were enough to make it quite an easy matter to pluck from 5 to 10 long stalks per day for my friends, always leaving many unplucked stalks.

[It is evident that our correspondent refers to either the Hymenocallis Harrisiana or H. rotata, both natives of the south, the former of Mexico and the latter of Florida, and both also remarkably pretty. The cultivation of these and several other species of the genus is not so extensive as it should be, especially in the warmer sections of the north, where it can be easily grown especially if the bulbs are stored in sand in winter as recommended for other bulbs. When grown in pots in the house the several species of stove and greenhouse varieties require a strong loamy soil, well drained, and a liberal allowance of pot room. The bulbs must be buried under the soil, as shown in the illustration (page 209), and always kept moist. - Ed].
