Aka "old man's whiskers" is easy to care:Plant directly into the soil 1/8 inch deep when a light frost is still possible.
Seeds will germinate in 10-20 days and plants will bloom the following year – after one season’s growth.
Apply an organic all-purpose fertilizer early in the season to promote strong, sturdy growth.
Prior to blooming, switch to a bud and bloom booster high in phosphorus to promote spectacular flowers.
Well these grow in a cold climate.
