Yeees. Something like, Coleus is so versatile! Its beautiful leaves make it interesting enough to grow as a single specimen or with loads of other annuals. It's a fast grower. If it grows too tall, pinch it back. That’s all there is to it!

In a small container, the upright spikes of summer-blooming angelonia seen here, https://felicita-flowers.com/en-gb/saint-petersburg/komnatnie-rastenija/ could be a focal point. But in a larger combo, it's a good supporting player, too. It benefits from a weekly dose of water-soluble fertilizer. Remove spent flower stems to help promote more blooms, too.

For a spiller I like sweet potato vines and you don't have to buy them every year. I store the tubulars in my garage in winter to replant the following summer. I haven't had any trouble with pests except for the large ones with antlers.
