Annual Vines for Part-Shade Arbor in DC: Black-Eyed Susan, Canary Creeper, Sweet Pea

DC area gardener wants an annual vine for a part-shade arbor (impatiens thrive there) that blooms all summer. Perennials don't bloom long enough.

Top Choices for Part Shade

• Black-eyed Susan vine (Thunbergia alata)—favorite, colorful, vigorous.
• Canary Creeper (Tropaeolum peregrinum)—yellow fringed flowers, climbs well.
• Sweet Pea (Lathyrus odoratus)—fragrant, cool-season but blooms into summer with care.

Growing Tips

• Start seeds indoors now; transplant in 30–45 days.
• Fertilize regularly.
• Well-drained soil, kept evenly moist—dryness stops flowering.

Black-eyed Susan vine is the standout for color and ease in part shade.
