Fleur, Those nicotiana and verbena are over 2 metres tall! I think they would look gawky by themselves, but luckily don't when together. Also, when it is windy, they hold each other up.
I sowed the nicotiana, but the Verbena bonariensis sowed itself

I wasn't sure that the foxgloves would like it here in Crete, so I only sowed a few and put those in shade, mainly under two apricot trees. They have been fine, so I will try some more next year.
Jills, I have a very small garden. Small enough to water by hand, which I do fortnightly in the summer.
It is still quite young. Nothing has been planted more than two and a half years. Next year I will try watering once every three weeks, apart from any new plantings, and see how that goes.
I do have in the garden a few fruit trees, which are very useful shade for some plants. The trouble is, I am very greedy

and have already run out of space.
Here are a few more combinations that I like.


Dahlia Arabian Nights and Rose Teasing Georgia have a similar flower shape, but I like them together.

Nepeta tuberosa with an ivy leaved pelargonium.

Rose William Shakespeare 2000 with Verbena x hybrida, a pink petunia, Nemesia denticulata Confetti. Lychnis coronaria and Rehmannia elata.

Pansy Padparadja being overtaken by Felicia amelloides.

Felicia amelloides and Erysimum Apricot Twist.

Nepeta Walkers Low with Alstromeria Polka and Phormium Jester.
