The frequent name “fire lily” has been applied to these diverse plants as gloriosa lily (Gloriosa), kaffir lily (Clivia), Scarborough lily (Cyrtanthus) along with orange lily (Lilium bulbiferum). On the other hand, the care of the first three is similar — they all need a dormant period and can be kept dry in a cool garage during winter. The kaffir lily will continue to need light, though, and shouldn’t be left unwatered for longer than two months.
Gloriosa Lily
Gloriosa lily flowers are in comparison to claws, with petals curling up like talons in their centers. Gloriosa rothschildiana boasts the biggest red and yellow blooms, while the smaller simplex stays more orange than red; lutea all yellow; and citrina mainly so. A tropical vine, gloriosa lily climbs by using the curling tips of its leaves like tendrils. Although considered hardy to U.S. Department of Agriculture plant hardiness zone 9 — or even zone 8 if protected — it is often grown in a pot, since it dies back to the ground in winter and needs to be kept dry during those months. Pick the gloriosa lily’s location carefully — it is very poisonous.
Kaffir Lily
The kaffir lily belongs to the identical family as amaryllis. The most frequent type — Clivia miniata– is the most amaryllis-like, with stout, strappy foliage and a cluster of orange, outward-facing blooms. You can also locate new yellow hybrids, such as “Sir John Thouron,” but must be prepared to pay dearly for them. In the wilds of South Africa, nevertheless, most kaffir lilies — such as Clivia caulescens, cyrtanthifolia, gardenii and nobilis — produce green-tipped reddish flowers that dangle like bows. The plant is only hardy to USDA zone 10, but it’s easy to grow in containers. It ought to be kept slightly stale bound, and demands a six-week cool and dry rest period during the winter to stimulate blossom in the spring.
Scarborough Lily
Also an African indigenous and member of the amaryllis family, Scarborough lily is known as fire lily since it blooms later flames have scorched its habitat. Again, the very popular form, Cyrtanthus elatus, flaunts the most amaryllis-like blooms. This time, however, they are red and decorate a lot slimmer plant. Other types, such as the pink delicata and yellowish ochroleucus, stretch more tubular blooms. Though some sources list these blooms as hardy to USDA zone 9, they need dry conditions during their winter season. The bulbs should, consequently, be potted in gritty dirt with the necks protruding, and kept under a roof during the winter to reduce root rot.
Orange Lily
The orange lily is a European wildflower similar to the tiger lily, named for the bulbils that dot its stems. The upward-facing flower’s color ranges from red to orange with maroon freckles scattered around its middle. Lilium bulbiferum var. Croceum is the strongest grower but lacks bulbils. Shorter and poorer, Lilium bulbiferum var. Chaixii generally manages only one or two blooms, but lots of infant coats. The orange lilies are hardy in USDA zones 7 to 10, and — like most lilies — must be implanted at least 4 inches deep in well-drained dirt.
