How to Grow Scarlet Pimpernel

It is best to sow Scalet pimpernel and similar species at a depth of 1/4 cm below the soil surface, with a spacing of 12 to 20 cm after the last frost of spring.

pimpernel prefers to be grown in full sunlight. The soil type is not important. Anagallis requires between 30 days and 45 days to germinate, it is best to plant seeds outside as transplanting pimpernel plants is problematic.

Anagallis is easy to grow and looks after itself, the only thing to remember is not to move the plant once it has been set as they do not tolerate being moved.
