Annuals Having Ornamental FoliageClimbing Annuals

Although most vines are woody or perennial, a few annuals can also be used in situations best filled by plants that reach heights of at least four feet and self-attach. Here are a few that can be successfully grown in Idaho. Most adapt better to warm regions rather than colder, high elevations areas. There are exceptions, such as sweet peas.

 

Common Name Scientific Name Regional Adaptation
Black-eyed Susan Vine Thunbergia alata N, SW, SC, SE, HA
Canary Bird Flower Tropaeolum peregrinum N, SW, SC, SE
Cardinal Climber Quamoclit sloteri N, SW, SC, SE
Climbing Nasturtium Tropaeolum majus N, SW, SC, SE
Moonflower Ipomoea alba N, SW, SC, SE
Morning Glory* Ipomea purpurea N, SW, SC, SE
Scarlet Runner Bean Phaseolus coccineus SW, SC
Sweet Pea Lathyrus oderatus N, SW, SC, SE, HA

*Ipomea is not invasive like field bindweed, which is sometimes incorrectly called "Morning Glory."

Key to regional adaptation notes:
N = Northern Idaho valley locations in USDA zones 5 & 6, Moscow to Sandpoint.
SE = Southeastern Idaho valley locations in USDA zones 3 & 4 from Rexburg to Pocatello.
SC = South-central Idaho Magic Valley locations in USDA zones 4 & 5, Burley and Twin Falls.
SW = Southwestern Idaho Treasure Valley locations in USDA zones 5 & 6, Boise area (also Lewiston).
HA = High altitude (>5,000 ft) areas of central, southeastern Idaho and similar locations elsewhere.
