An even more intoxicating scent is emitted by the four o'clocks, Mirabilis jalapa, so called because it opens its blossoms late in the day. It seems to be classified as an annual, but does come back from its roots here, as well as self-seed prolifically, abundantly. I am constantly pulling up errant seedlings all during the growing season. But, oh, to enhale that luscious odor at twilight is certainly worth a bit of effort. I wish I could post a sample of that scent here instead of merely a photo of its simple flower. Mine are a hot pink but they come in a variety of colors as well as multicolored. I took some seeds from a plant growing more or less wild alongside a former railroad track in the middle of the city.
There are some others, but as this post is getting lengthy, I think I'll write about them another day. All of these plants make themselves at home in both some sun and even in quite a bit of shade where they might not bloom prolifically but at least do provide carefree foliage. I let them sort themselves out as to who gets to be dominant in their various gardens areas, and they carry on with panache. The other morning a woman walking her dog complimented me on the display out front, and when I replied that everything there was easy to grow, she said, "that's your secret."
