ments are being carried on with this parent by which it is 
expected to realize some new hybrids this summer. 
The day-blooming lilies do not stand the “drying off” 
treatment as the lotus type does. If grown as perennials, it 
is necessary to plant them in tubs in the winter. However, 
better results are obtained by treating them as annuals. The

Hardy Nymphaeas.—The native lilies and their hybrids 
are perfectly hardy, that is, the rhizomes or roots may be left 
in the ponds throughout the winter. The best hybrids have 
originated from three native species, Nymphaeae odorata, 
white, NV. odorata, pink, and N. flava, yellow. It was 
this yellow-flowered variety—that attracted the French 
hybridist, Latour Marliac. He crossed N. tuberosa and N. 
flava, thus originating the beautiful hybrid, N. Marliacea 
chromatella, The influence of this yellow species may be 
traced in the majority of hardy lilies. The first hybrid that 
appeared in sink or rose was NV. Marliacea rosea in 1887, 
the parentage of this plant being known only to the-hybridist. 
The European rose-colored lily, Nymphaea alba rosea was
