This year I've had great success with tulip 'Spring Green' and globe thistle (Echinops ritro).
Here's 'Spring Green' in full flower, the same image as a couple of posts ago.
The globe thistle is visible in the middle of the clump.
As the flowers faded, the thistle was just rising above them.
A few days later when I removed the spent stems, the thistle had expanded enough to neatly cover what was left.
In a month or so, it will produce its own flowers, lovely steely-blue balls on long stems. I'll post a picture when it happens.
