Grown from seed Heliotrope will flower later in the same season. Pinch off faded flowers to encourage more to form. will flower late into autumn until the frost.
Mature plants can be lifted and over wintered under protection of fresh plants started from seed again in the early spring
Heliotrope can also be grown as a house plant in a cool conservatory
Start seeds under protection sow thinly in a 7cm pot or module in very early spring. Once germinated pot on when just large enough to handle into individual pots and grow on under protection
Try to aim for a seed spacing of at least 0.78 inches (2.0 cm) and sow at a depth of around 0.04 inches (0.1 cm). Soil temperature should be kept higher than 15°C / 59°F to ensure good germination.By our calculations*, you should look at sowing Heliotrope about 77 days before your last frost date .
Pot on as necessary and plant out only after all danger of frost has past in mid summer. Choose a sunny well drained spot at the front of a border or path edge. Heliotrope is also good in pots and containers
Ensure that temperatures are mild (minimum night temperatures should be around 5°C / 41°F) and all chance of frost has passed before planting out, as Heliotrope is a tender plant.Can be used as cut flowers
After flowers have faded, cut the ripening seed heads into a paper bag. Continue to dry on a warm windowsill until the seeds can be shaken from the seed heads.
