Hummingbirds favor tubular type flowers, so you have many options. I would think twice about morning glory (the one with large purple flowers), unless it is in a container and you keep it trimmed. Honeysuckle or jasmine are good choices.

Thanks 1gteacher. I'll probaly put some jasmine on my trellis.

Coral Honeysuckle is good or major wheeler which is mildew resistant and aphid resistant. Hummers love and use both of those here.
