Incredible "Red Velvet Shamrock"--a striking selection with handsome dusky glowing purple foliage with a central vivid violet flame on each triangular leaflet; low statured mound topped with many delicately toned lilac fls. A knockout with a distinct winter dormancy cycle (unlike the species) if allowed to dry out or to chill, or even experience very low light levels. Has been featured and pictured in many articles recently; has also increasingly added new names to its nomenclatural chaos. Leaflets have chevron design unlike the solid purple of Oxalis Floribunda.

| Family | Oxalidaceae |
| Plant Details | |
| Cultural Code | HP CGH |
Some of you grow only indoors, some only in terrariums; many of you have hobby greenhouses; while a growing number of customers live in subtropical or tropical areas of the world. These brief codes are an attempt to suggest whether or not a particular plant will do well in your particular conditions.
If an entry has the cluster HP CGH, this means normal house plant culture will be successful if the plant is given a cool CGH moist location; however if the entry has the cluster CGH HP, you would interpret this to suggest that while Cool Greenhouse conditions are needed for total success with this plant, House Plant conditions will be adequate, while not ideal. If the cluster is HH CGH you would interpret this to mean that while in Zone 8 or below this will be winter hardy outdoor, further north it will need considerable mulch, a cold frame, or a Cool Greenhouse to thrive. And so on.
