I grew the blue bacopa from seeds this year. I got them from Ebay. They are tiny little seedlings, but almost all of what I sowed in the house under lights grew. I put some in a hanging basket and some in a pot with other plants. Both were in full sun from 7 am till about 8 pm. They are still in full bloom. I'm going to try bringing them in the house for the winter in the next few days as it supposed to frost.

Were they hybrid varieties to begin with? If so then what you will get from their seeds normally will be two to four (on average) different types depending on their parental lines. That is assuming only two parents. If they were older open-pollinated (heirloom) varieties then their seeds will usually breed true. And since you cross-pollinated them the variables increase to 16-20 if hybrids. So you will need to grow out most of the seeds, select the ones with the characteristics you want to keep, grow them out, select again, etc. Normally it takes 6-7 generations of selecting and growing out to stabilize a cross-pollinated hybrid variety.

The issue is are they hybrids or heirlooms/open pollinated varieties. If they are hybrids then the seeds you save won't breed true. Hybrid seeds in the packet are the result of manual cross-pollination of at least 2 parent varieties. The seeds saved from those hybrid plants once grown, will revert to the parent stock or some strange combination of them. If your seeds planted and grown are heirlooms or open-pollinated plants, not hybrids, then yes you can save the seeds and re-grow them. Depending on what the plant is - self-fertile like tomatoes or insect pollinated like most flowers, they may or may not grow true. In some cases, like hollyhocks you will still get lots cross-pollination by insects so your saved seeds may change color etc. It all depends on how much you care whether or not the seeds you saved breed true or not. Many don't care, many do. Some research on cross-pollination will explain this in more detail. ;) Dave

Kerria, forsythia, mahonia, hypericum will all produce yellow flowers but none of them are very large. They tend to make up for lack of size with abundance :-) Try Googling with the botanical name and seeds - that should provide a number of sources (it did for the kerria and hypericum). But I too would start out with a small plant........growing just about any woody plant from seed is a long, multi-year process to get to a flowering stage.
