I first planted this a couple of years ago with some seed sent in a swap. Thinking it was rather delicate, I sowed seed in a semi-shaded...Read More location beside an unattractive post. It grew and turned an eyesore into an attractive spot in the garden. It did not reseed, nor did it return the next year. This year, I came across some of the seed I had saved from that plant and planted them in full sun under a pole supporting a hummingbird feeder. I suspended some twine from the hooks and fully expected to be cutting that twine off when the old seed failed to sprout.

It grows two stories tall in full sun on my front stoop in a small planter with limited nutrients competing with mint, and equally vigorously in more than half a day of shade in hanging baskets.

A lovely, nice delicate plant. Reseeds easily, but is not invasive. Very recommended!

It will grow just as well in the ground. I'm in California (U.S.), and they appear to be a perennial, though usually treated as annual in other parts of the country. They love my roses and add such a delicate balance to the garden.
