Yes, it may take me a bit but I will see what I can put together to send you and if you don't want or need what I send, share at will.
The Papalo is an odd seed to germinate. I think it produces loads of seed due to low germination but the plant is sturdy in the summer heat. As much as I like Cilantro, the verdict is still out on Papalo. It is an unusual taste/scent.
I love Underwood Gardens. I have bought from them in the past. Their site has great information and they have some unusual plants. I always look for plants better suited to our summer heat. Sometimes I win and sometimes the summer temps win.
And if anyone else reading this thread wants to try some of these herb seeds, I will share. Just let me know...
A smaller lettuce that I love for winter growing is Little Gem. It is a small romaine although I don't care if it forms heads. I trim it like a loose leaf and love the taste.
