They grew real easy for me. I planted a couple of plants and all the other popped up in the yard. Best of luck to you. I hope to see pics of them growing in your garden.
Dry garden, little irrigation, 9" precip
Shoshone Idaho USA. Zone 5b-6a
Hot and dry in the summer, cold and snow in the winter.
The Alplains catalogue says to cover seed (though not indicated as being necessary) and to cold stratify for 8 weeks. Then there is usually germination once the seeds are brought out to warmer conditions. So, stratification is recommended, as is the case for most penstemons.
I don't know what your winters are like. If you don't really get a winter where you are (?), you could always stratify the seeds in a damp folded paper towel in a plastic bag in the refrigerator.

-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
Our winters are mild by your standards but we do get frosts and can drop down below 5oC most winters (the worst was -7oC!) so I'll cold stratify them in pots outdoors; still too hot here this week to start seed sowing And next week the tops are only in the low 30s (oC) so we hope the cool weather will be here soon,

Hi Aaron,
well I've got my seeds and I hope to get them sown when the weather cools down a bit. Hopefully they will get to be like yours and start to self sow!
cheers
