Globularia members such as Globe daisy can be sown outdoors in either late autumn or the start of spring. The seeds should be sown on the surface.
Globe daisies are able to grow successfully in sunny and partially shaded areas. They prefer a moist soil of pH 5.5 to 7.
The spacing is species dependent: sow small Globularia species 12 to 20 cm (5 to 8 inches) apart; and larger Globularia varieties about 30 cm (12 inches) apart.
If starting off indoors, you should first chill Globularia seeds in the fridge, within soil (in a bag) for three weeks.
Sow them about a month and a half in advance. It should take from one to seven weeks for Globularia to germinate in the light, at about 12 degrees centigrade (54°F).
Transplant them into the garden a week or so after the last chance of a frost.
As globe daisies and other Globularia plants like a moist soil, it is best to water them on a regular basis.
They also require an occasional application of fertilizer. Once flowering has finished cut back to encourage a second bloom in autumn.
If you require more globe daisies then propagate by division in the spring.
