FAQ
Does Sand Penstemon need sandy soil?
It is best suited to sharply drained sandy or mineral soils. Avoid heavy, constantly wet beds, especially while seedlings are establishing.
Do the seeds need cold stratification?
Many penstemons germinate better after a cool moist period. Fall sowing outdoors or refrigerator stratification before spring sowing can help.
Is it useful for pollinators?
