We have such voracious birds around our house with a predilection for tender shoots that I found it impossible to raise seedlings until The Husband devised this makeshift greenhouse on a rack for me. I am raising echinacea seedlings this time. They'll give flowers in 3 years time. Along the way, some will die so I made sure I seeded many pots.
The seedlings are fragile and need careful tending. They grow rather slowly too. It takes a fair amount of patience and 5 minutes every morning. But this plant is really important to our family so I guess I'll just have to make time. See here and here, for the use of echinacea.
