How to grow Cape daisy 'Superbum'

  • Medium

Keep in mind when planting that Superbum is thought of as half hardy, so although it can survive a small mild cold snap, it is wise to ensure that this plant is protected from frost damage.

Growing Superbum from seed

Sow 0.04 inches (0.1 cm) deep with a guideline distance of 11.7 inches (30.0 cm). Soil temperature should be kept higher than 18°C / 64°F to ensure good germination.

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

Transplanting Superbum

As Superbum is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.
