Hollyhock 'Creme de cassis'

Hollyhocks in general seem to suffer from ‘rust’
After flowers are faded the plant can be cut above ground level and it will grow back. Flowers will open in fall.¹
but flowers in subsequent years are not as good and rust often takes hold

Position in a full sun location and remember to water moderately. Keep in mind when planting that Creme de cassis is thought of as hardy, so this plant will survive close to or on freezing temperatures.

Sow thinly into pots or modules in mid summer using ordinary potting compost. As soon as the seedlings are large enough to handle pot on individually

Try to aim for a seed spacing of at least 0.2 inches (0.5 cm) and sow at a depth of around 0.1 inches (0.25 cm). Soil temperature should be kept higher than 12°C / 54°F to ensure good germination.

By our calculations, you should look at sowing Creme de cassis about 56 days before your last frost date.

Plant out at the end of the summer into the final flowering position in a sunny situation using a wall to set off the flowers and provide protection from the wind
Hollyhock can be used in borders in sun, on well drained soil

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Creme de cassis is a hardy plant.
