I cant give up, so I let seeds that wont germinate have more than a fair chance and don't toss them quickly. it took over 3 weeks to finally germinate.

Agustina Nader

I’ve had these sprouted for maybe 3 weeks now. They’re quick to sprout.

Fidel Marvin

Sprouted right after planted.

Clementine Feil

Not sure if they will look good yet. At least the germination rate was great.
