Annual Mallow 'Silver Cup'

Keep in mind when planting that Silver Cup is thought of as tender, so it is really important to ensure that the outside temperature is well above freezing before planting or moving outdoors.

Look to ensure a distance 11.7 inches (30.0 cm) between seeds when sowing - bury at a depth of at least 0.12 inches (0.3 cm) deep. Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Silver Cup is a tender plant.
