This species is closely related to, and perhaps not specifically distinct from
L. pilosa. Differing from L. ciliosa in its smaller leaves; flowers with more
slender tubes, lips more pronounced and glabrous style. In European
gardens L. arizonica, L. ciliosa and L. pilosa are very rare. If you like this
kind of flowers it is better to choose L. semperivens ́Superba ́ or L.
×brownii ́Dropmore Scarlet Trumpet ́ known for their hardiness.
