yellow four o’clocks in my garden, 8:30 pm
When we were at Monticello last summer I was struck by how large Thomas Jefferson’s four o’clocks (Mirabilis jalapa) were compared to mine. I also liked the fact that it was a plant he knew and grew and could still be grown today as an heirloom. Although I had a few small plants in dry, lean soil in full sun, I was inspired to start new plants from seed this year. I planted them in very rich soil, under morning sun and afternoon shade. Yes, Virginia, despite our heat, humidity, and lack of rain, they are growing very well. They are about 2 feet tall with light green leaves and many yellow or pink blossoms.
The only trick is that the flowers do not open in the day. Although they are named for opening at 4:00 pm, mine never do. The tubular blossoms are sensitive to light and temperature and prefer to open during the cool of the evening, usually between 4 and 8 pm, and stay open all night long. Currently we are in the midst of a heat wave so they do not seem to be opening fully.

Flowers come in pink, white, red, yellow, magenta, or mixed, liked speckled. They are tender perennials which means they will grow as perennials in the south but in my zone 7 garden, I can grow them as annuals that may not overwinter, dig and save the tubers for next year, or start new seed next year. Four o’clocks were cultivated and selected for various colors by the Aztecs prior to the Spanish Conquest. They were then introduced to Spain and England and were in cultivation in Europe for about 200 years before Linnaeus first described the species in 1753. Thomas Jefferson received his from France. In July 1767, exactly 250 years ago to the month, he noted in his journal “Mirabilis just opened, very clever.”
Garden Bloggers Bloom Day occurs on the 15th of the month. Garden bloggers from around the world post their articles about blossoms in their garden.

Lovely four-o’clocks!
They remind me of my mother
Happy Garden Bloggers’ Bloom Day!
I have four-o’clocks also in zone 6b/7a, lower middle Tennessee. They were started from seeds, have spread everywhere and I have never dug any of them up before winter. For me, they have survived the winter weather fine; however, they are the very last thing to sprout in the Spring.
When my sons were small they would try to guess which one would open next. Ripping the bud open did not count as winning.

that is a cool story, what memories!
It was free entertainment that kept them outside. Now, you try guessing which one will open next…when you have nothing else to do.
