NIEREMBERGIA

Small genus of plants from sunny, moist areas in South America. Species include a spreading mound and a ground-covering mat. Both are blanketed with broadly cup-shaped blooms in summer. Beyond the hardiness range, treat these perennials as annuals.

Nierembergia linariifolia

Grows to 6–12 in. high and wide. Much-branched, mounding plant, with very small, stiff leaves. Flowers are blue to violet. Trimming back plant after bloom to induce new growth seems to lengthen its life. ‘Purple Robe’ and the white ‘Mont Blanc’, usually sold as N. hippomanica, may be varieties of the similar N. scoparia. ‘Augusta Blue Skies’ is a compact hybrid with lavender-blue flowers and improved heat tolerance.
