Mirabilis prostrata is a broadleaf deciduous perennial bulb / corm / tuber with green foliage. In summer pink flowers emerge. Grows well with sun and even moisture water. Does well in rich and well-drained soil.
I'll start with the disclaimer, because I know how some of you worry - don't panic! In contrast to the brash & thuggish Mirabilis jalapa, this airy & girly Chilean wildflower is just as polite as can be, reseeding very minimally if at all. Feel better? Good. Unknown in the garden world, what info we did find led us to believe it would have a strange habit, with long low stems leading flat along the ground, but ours grew bushy & erect to 2' high & wide, producing a cloud of 3/4" blooms in a pretty purple-pink. Bloominess went on for a month or more before the plant started to transition to seed-making mode. By Fall, the plants died back to their tubers. Dormancy lasts until mid-late Spring, when it will peek back out of the soil & do its thing again. We grew ours in cushy amended garden soil, but I'm betting this plant will take a rougher patch of earth & drought with no fuss!
