Sugar star phlox is an annual plant producing pretty, blue-violet flowers with a delicately scented, star-shaped white center. Perfect for brightening up a sunny border. It withstands dry spells well. It holds up well in a vase. They produce nectar and honey, and attract butterflies. Height: 50 cm.

Sow in March-April in pots of fine seed compost. Phlox seeds need darkness to germinate, so sow them 3-4 mm deep. Press lightly.
Water and keep moist until emergence.
Place the seedlings in a sheltered greenhouse or under a frame with sunny exposure.

It is possible to sow directly in the garden from May to June. Sow by broadcasting or in pockets and cover with 3-4 mm of fine seed compost. Keep moist. Thin out to leave 15-20 cm between plants.


Plant in May when frost is no longer a risk.


Water the plant regularly during hot periods.
Remove faded flowers.
Cut back the plant after flowering in the fall.


Sow from July to September.
