How to Grow Globe Flower and Other Trollius
It is best to sow Globe flower (and other Trollius) seeds outdoors using fresh seeds in early autumn; sow on the soil surface in peat pots, and sink the pots about 30 to 45 cm (12 to 18 inches) apart into the garden in a shady area, keep well watered.
Use a few seeds in each pot as Trollius suffers from poor germination> It may be easier to grow from purchased plants or divisions took from established plants.
The seeds should take from one month to one year to germinate.
Ideally they should grow in a shady part of the garden, they will tolerate sunny areas but keep the soil well moistened, almost boggy if growing in these areas.
Ideally the soil that they grow in will be sligtly acidic to neutral (pH 5 to 7) and humus rich.
Caring for Trollius Plants
When looking after Trollius species such as Globe flowers it is important that the soil they grow in is very moist so keep well watered.
Once they have finished flowering dead head them, this should hopefully result in prolonged blooming of globe flowers.
If you require more plants then propagate by division in either spring or autumn, however, it is important not to do this too frequently, perhaps every three or four years at the most.
