Hardy in zone 3, Calgary, Alberta, Canada.
Not problematic to grow in this drier climate. Does not go dormant in summer here.

This is the second most popular Parryi primula species. All of this group are native to western North America. This one, specifically, is native from Mexico north to New Mexico and SE Arizona where it grows on damp, shaded limestone cliffs and ledges. It is challenging in cultivation as the plant needs to be kept dry over the winter but needs plenty of moisture in spring and summer. This species is quite similar in appearance to P. parryi but is overall smaller.
