Way back in spring I planted some lavatera, nicotiana sylvestris cardoon and verbena bonariensis from seed, in order to "fill up" this garden which was only started last year. Yikes!! They're all huge and blooming away now. You can't even see the cardoon at the back and I have to keep cutting the self-seeded borage back. But still, annuals are a great way to fill up space while you're waiting for your perennials to mature. I think I'll skip the nicotiana sylvestris next year, though. It just takes too long to get big - in the spring you wish it would fill up a spot faster, and now it's so huge you can't walk on the pathway beside it!!
