Propagation Notes -

For viable seed -
Start with two or more mature plants. Many times flowers develop in the first season. Collect seed late in the fall once they are brown. Only collect seed when it is dry, never after it has rained. Store in a paper bag. Once seed has set for a few weeks move to a container with a lid. I save different sized containers through the year.

Germination
- Best results - We collect our seed and plant it outside in a well drained flat, protected from heavy rain. Old windows work great! If it is a warm dry winter flats will need to be occasionally watered.
