I bought this plant (the one in the base of the citrus) as a 6″ annual for an outdoor hummingbird container I was planting in 2015. It was called “Jewels of Opar” (don’t you love common names sometime? They’re so romantic!) The botanical name is talinum ‘limon’ presumably for the chartreuse foliage.
As I was scouting around for the botanical on this, lo and behold, I also discovered it was edible! Gracious! This really is the plant that keeps on giving! When I entitled the post that, I merely meant that since 2015, it has self-sowed into various containers of mine and continues to bloom all over the place. You see it here in 3 containers in 3 different stages: blooming, near bloom, and seedling.
It was blooming outside in my garden beds as well. When I find these flower stalks going to seed, I shake the seeds over my beds and borders and the next season I find plants coming up in the gardens. How delightful. Plants without work. I am all for that!
The article I link to above makes mention of how wonderful these itty bitty tiny flowers are for pollinators. So many of us grow huge hulking flowers to draw in bees and butterflies but we forget about our smaller bees. There are bees that are the size of a grain of white rice and we need to be mindful of those pollinators too!
Of course, if you are going to attempt to eat what you are growing, make sure that you are growing it organically. No pesticides of any kind, especially on the plants but even in your soils. Be mindful of that.
Otherwise, just enjoy these lovely plants and flowers.
