I have an antique ornamental structure that I think was intended to be a tomato cage, but I find it impractical for that purpose, so I decided to use it to dress up the garden. I have a row of zucchinis and a row of crooknecks with a space in between intended for a companion--but I have so many nasturtiums, marigolds, etc. that I'd rather just do something pretty that won't hurt, rather than worry about extra help. The cage is only about 3 ft. tall, but I'd like something to climb and wrap around it to give a nice spot of bright color. Suggestions? Is passion flower friendly with zucchini? I had thought of that with our hot, dry climate (Southern California). Thanks!
