In appropriate locations, the Flame Vine may present its vigorous growth with lush, evergreen

leaves. In its native country, Brazil, it climbs fast by twining or tendrils to a height of 24 metres

under perfect conditions, but is limited to about 14 metres in cultivation. The tendril is a mo-

dified leaflet at the tip of a compound leaf which twines around anthropogenic structures such

as a fence, or a natural support such as trees. Such overgrowing may result in invasions that kill

shrubs or small trees in the vicinity. In its homeland tropical South America, where no frosts

occur, dormancy may be induced during a brief period of dryness. Twigs take some frost, but

protected sites are recommended initially, especially in Arriyadh. Plants recover readily after

hard pruning, which is best done after flowering. Most striking is its spectacular flowers that

measure up to 8 cm across. Abundant clusters of bright-golden or orange flowers show up mainly

in early summer, and sporadically throughout the year. They are tubular, curved and waxy. They

are followed by pods of 30 cm in length. Flame Vines do best in full sun with moderate to ab-

undant watering, and respond well to fertiliser. They can be trained along a pergola, but should

be allowed to drape over structures, since the best effect can be achieved when the flowers hang

down. They are most often multiplied by layering and cuttings. They can also be propagated at a

small scale by separating suckers.
