Calling out for attention, Penstemon heterophyllus 'Blue Spring' (Foothill Beardtongue) is a clump-forming evergreen perennial boasting a spectacular display of wide-mouthed, tubular bright blue flowers tinged with pink in spring and summer. The profuse blossoms are borne on upright, branching stems and rise well above the foliage of narrow, shiny, bluish-green leaves. They attract scores of hummingbirds, butterflies and other beneficial pollinators. Long-lived, easy to grow, fuss-free, deer resistant, Foothill Beardtongue 'Blue Spring' is a seed strain of the outstanding California native Penstemon heterophyllus. It is perfect for the sunny water-wise garden and looks dramatic planted in masses in a dry mixed border.

  • Grows up to 12-18 in. tall and wide (30-45 cm). Often self-seeds in the garden.
  • Performs best in full sun in moderately fertile, sharply-drained soils. Water three times per month in summer once established. Drought tolerant.
  • Provides a charming impact in beds and borders, city gardens, cottage gardens, coastal gardens, rock gardens, Mediterranean gardens. Plant in bold groupings.
  • Keep an eye out for slugs, snails, aphids, leaf and bud eelworm, grey mould, powdery mildew and fungal leaf spot. Deer resistant.
  • Prune any winter-damaged stems back hard to encourage fresh new growth from the base. After flowering, shorten flowered stems by half (unless seed is required) to promote more blooms.
  • Take softwood cuttings in early summer or semi-ripe cuttings in midsummer or propagate by division.
