Description

This tiny perennial wildflower (Talinum / Phemeranthus calycinum) produces ascending stems 2-6" long topped with bright magenta flowers. The cluster of bright green foliage at the base is only a few inches tall and resembles round tubes giving it a succulent look. Blooming occurs in mass, each flower lasting only 1 afternoon, but repeating all summer with available moisture. Fame Flower is native to a large area of the great plains to the eastern woods of Missouri and Arkansas. This cold hardy succulent occupies an unusual niche: growing in extremely shallow sandstone based soils and on sunny rock cliffs that dry out too quickly for most other plants to colonize. A good question is how does it find such isolated areas to colonize in the first place? Grow this small native gem in a rock garden, in cracks between rocks, or on top of or in a retaining wall. It will re-seed to thicken the colony but only germinate in bare thin soils with no mulch. It will not tolerate competition in rich moist soils as other plants will shade it out. If grown in pots and kept on the dry side, you may leave out all winter allowing to freeze solid; plants will either return from dormant stems or reseed in the same pot. Great low maintenance cold hardy succulent. ADDITIONAL INFORMATION ABOUT CREVICE GARDENING: In nature, some of the most interesting xeric plants grow in tough places such as inhospitable rock outcroppings with almost no soil. We can recreate that specific and exclusive growing environment with a crevice garden. Crevice gardening allows you to grow cold-hardy cacti and succulents that are normally cold hardy to our climate (Lawrence, KS zone 6a) but not normally tolerant of excessive moisture (40"/year), especially in the winter. This technique provides optimal xeriscape growing conditions by limiting the amount of soil and water around the roots and reducing the potential of root rot. Start with a raised mound of fast draining soil mix consisting mostly of decomposed granite, coarse sand, gravel, and a small amount of organic matter. Incorporate vertical rock formations such as flagstone into a raised landscape bed creating narrow 1-2" wide crevices filled with the soil mix. This helps quickly channel rain and snow melt water down more deeply into the soil encouraging deeper root growth while keeping the soil dry around the base of the plant. It is important that the entire mound is well above grade level to avoid drainage problems; crevice gardens typically range from 12"-36" tall. After installing the plants, mulch with a thin layer of pea-gravel or decomposed granite. In our Lawrence Kansas zone 6a winters with occasional polar vortexes or arctic blasts, this technique works well in any hot microclimate such as a south facing side of a berm or under a south or west facing roof overhand of a house or building. Kansas Plant Farm LLC built a trial crevice garden in 2022 and we have now had enough time to evaluate the plants after a true winter cold spell. During the arctic blast of January 2024, low nighttime temperatures got down to -11 degrees F (Jan 10th,2024). The longevity of this cold blast was also impressive: 4 days on a row with single digit highs including 1 day with a daytime negative high(-2F), 4 nights of lows in negatives (-8For lower), and 48 straight hours of 0 degrees F and mostly lower. A light snow cover helped insulate the ground but wind blew off most powdery snow on the foliage exposing the top parts of the plants to some extreme temperatures with surprisingly little damage. In our crevice trial gardens in Lawrence, KS (zone 6a), this variety survived harsh winters for 20 plus years.
