A 15 sq m terrace makeover: simple and clean is a kind of beauty too

A beautiful 15 sq m "terrace makeover." After seeing the flowers grown by the experts, I got hooked. I happen to have a small terrace, so I'm tinkering with it too. For now there isn't a single flower, so any tips are welcome!
A beautiful terrace - I immediately couldn't help imagining all sorts of things for it
A gorgeous terrace, so enviable, so beautiful
Plants: potted red roses, plus a group of coleus (Solenostemon scutellarioides), both add a cheerful tone to the whole space.
For plant arrangement, I follow the garden's spatial structure, from inside to outside and from low to high.
Simple and clean - this is also a kind of beauty
The petunias sown in summer have finally bloomed. Although they have no shape and are a bit thin, at least there are flowers. I hope the Catharanthus roseus and rain lilies I just sowed will also bloom on my balcony.
Carbonized wood is a garden decoration material that has risen in popularity in recent years. After high-temperature carbonization treatment, carbonized wood has strong rot resistance.
The terrace at night - the soft glow adds a touch of tranquility to life on the terrace!
