The perfect spot for Malvaviscus drummondii (Dwarf mallow), would be in full sun, or semi-shade and regular amount of watering. The off-white flowers, with a hint of crimson, are also a magnet for butterflies. It also enjoys a rich, moist soil and compost should be added to the soil when planting. This plant can survive in USDA Zones 8-10 and a mature plant can cope with cold hardy temperatures of at least mid-20sF for a short period of time.
For pot grown shrub in cold regions, the optimal spot for it is to choose a sheltered spot to get partial shade in summer. Water regularly, so that the soil doesn't dry out, but avoid overwatering as this will cause root rot. Keep containers well insulated, mulch the surface and wrap outdoor containers in bubble wrap and insulated fabric. In case of extended cold temperatures, it is better to move it indoors or at least bring the pot to a sheltered position, as this will ensure the survival of the plant.
