Yellow Trumpet Vine

Follow a regular watering schedule during the first growing season to establish a deep, extensive root system. Feed with a general purpose fertilizer. Provide support such as a trellis or arbor. Prune annually to control size. Pruning time: summer after flowering.

This lovely tropical appearing vine is much hardier than expected. One of the few trumpet-flowered vines that self clings, its little suction cups are easy on masonry. Plant it out of the wind but in full sun to cloak a wall in golden yellow. Stunning when trained up buff-colored classical columns or pilasters. Let it wind its way through very large-dimensioned latticework, or send up on the roof, where it blooms with vigor in warm climates. Perhaps the best vine for sculpting over windows and doorways in warmer climates.

To create a frost-tolerant semitropical garden, combine this Trumpet Vine with fragrant plants such as Star Jasmine (Trachelospermum jasminoides), First LoveTM Gardenia (Gardenia jasminoides 'Aimee') and Variegated Winter Daphne (Daphne odora 'Aureo-marginata'). Lovely mixed with the lavender Little Grapette Miniature Daylily (Hemerocallis hybrids Little Grapette) and Mini Pearl Miniature Daylily (Hemerocallis hybrids Mini Pearl). Then, spot in Silvery Sunproof Lilyturf (Liriope muscari 'Silvery Sunproof') for foliage variation.

This vine and its kin are mired in a complex, changing nomenclature within the family Bignonia. Alfred Rehdr of the Arnold Arboretum listed the genus as Doxantha and later it was dropped altogether and given Macfadyana to include only four species. The vine is native to the American tropics from Mexico south to Argentina. The ungus-cati is from the Latin for cat's claw, referring to the shape of its climbing holdfasts.

Trumpet vines of all kinds are exceedingly attractive to hummingbirds which can reach deep into the flowers for their nectaries.
