Although they will grow well enough in pots, these lilies are quite worthless for pot culture.
One of the best of the Isolirion group of lilies is Lilium Batemanniae. This plant resembles L. Elegans in some particulars, but its blossoms are quite distinct. They are of a rich unspotted apricot colour. The perianth is more reflexed than is commonly the case in this group. It flowers in the late summer. It should be grown in a good peaty soil.
Lilium Wallacei, a very similar species, has the flowers of a rich apricot, densely spotted with black. The bulbs of this species are very small. It requires similar treatment to the last.
Lilium Philadelphicum is an American species, and has a rhizomotose bulb. The stem produces a single blossom, dirty orange colour spotted with black and yellow. It requires a wet, very peaty soil.
Another American species is Lilium Catesbaei, a very curious and interesting plant. The bulb is unlike that of any other lily except L. Avenaceum. It somewhat resembles a fir-cone. This plant grows to the height of about a foot. It produces a single blossom, about five inches across. The segments are curiously curved and curled. Its colour is reddish orange and yellow. It should be grown in a peaty soil, but it is a somewhat tender species, and is not really suitable for outdoor culture in this country.
We have hurried through this group of lilies because the species are not remarkable either for form or for colour. They are certainly inferior to any other of the genus lilium.
