Echinacea

I've just planted a couple of these in the garden.
Having been caught out by certain other plants that have spread all over the place once they got established I wonder if these have a tendency to propagate themselves by creeping roots or other crafty methods. Any advice welcome.

 

Which ones? Some are more likely to spread than others, though seeding is more likely than root running.

 

Echinacea purpurea (coneflower) was one. I lost the packet of the other but it was a white as opposed to the aforementioned pink variety.

 

Echinacea purpurea (coneflower)

This one in my garden is not invasive in the least - it don't spread, and it don't self seed easily even leaving the seed heads all winter - collecting them and trying to germinate in the spring. Prolly the conditions are not right!.

However I have a yellow variety - that was sold as yellow coneflower, but whilst having the same bud openng is likely to rudbeckia - is definitly one that root runs - not a thug, but definitly a spreader.

The white variety of echinacea is not one I have grown so.

 

Neither of those two are a problem. Seed needs to be sown fresh and over wintered.

 

My Echinacea purpurea is not at all invasive, it is almost too slow to bulk up. Though it will grow easily from seed up in a seed tray.
