my bf's mother has just brought me back some seeds from her hols in Arizona and Nevada. can anyone tell me the best ways to germinate them and where to grow them as the instructions are a bit brief.

the first is just a mixture called 'desert gatherings' including: Brittlebrush, Desert Marigold, Mexican Poppy, Chuparosa, Fairy Duster, Owls Clover, Desert Lupine, Prickly Poppy, and Penstemon.

the second is some seeds called 'Indian Paintbrush' (Castilleja sp.)

and the last is 'Desert Globemallow' (Sphaeralcea ambigua).

Thanks!
