Garden Bloggers Bloom Day: Four O’Clocks

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.

8th Annual Heritage Harvest Festival, September 12-13, at Monticello, Charlottesville, Virginia

The 8th Annual Heritage Festival is presented by the Thomas Jefferson Foundation at Monticello in partnership with the Southern Exposure Seed Exchange. Thomas Jefferson is often called America’s “founding foodie”. He championed vegetable cuisine, plant experimentation, and sustainable agriculture. Each year the Heritage Harvest Festival honors Jefferson’s legacy with this fun, affordable, family-oriented, educational event promoting gardening, sustainability, local food, and the preservation of heritage plants. Participants enjoy tastings, workshops, hands on demonstrations, interpretive walks, and a variety of garden tours and exhibits. Friday and Saturday offer more than 100 programs and workshops, 90 vendors and exhibitors, and sample food from local farms and restaurants. On Friday evening, Aaron Keefer, the culinary gardener of The French Laundry, will offer the keynote speech and there will be a Chefs’ Harvest Dinner on Montalto, Jefferson’s high mountain overlooking Monticello. This year an additional pre-festival program on edible landscaping will be held at Montalto on Thursday, September 11.
