Penstemon barbatus 'Twizzle Blue' - BEARD-LIP BEARTONGUE 'TWIZZLE BLUE'
Narrow upright plant with evergreen basal leaves. Wonderful transparent vertical accent for sunny and dry garden.
Shorter-lived perennial - the clumps have to be divided to renew the vigor of the plant, or can be grown from seeds.
Blooming Time: May/June to June/July
Size: 35" tall and 12-18" wide
USDA Zones: 5 to 8
Culture: full sun, partial sun. Best in soil with some drainage (gravel, coarse sand, haydite, gritty soils, sandy soils). Avoid waterlogged and wet soils. We have succesfully grown the 'Coccineus' cultivar (orange-red), which is not bothered much by the humidity and heat, so we expect this one to be as good.
Moisture Needs: medium-dry, dry
Origin: Introduced by Van Hemert & Co., as a part of Twizzle Serie. The species of P. barbatus is native to AZ, CO, NM, TX, UT, where can be found on rocky slopes, open woodlands and mesas
Deer/Rabbit Resistant: yes / yes
Attracts Butterflies or Pollinators: yes - pollinator friendly
Attracts Hummingbirds: yes
Pot Size: square 3.5" x 4" deep perennial pot
Plant combinations: Xeriscape, dry beds with drained soil, rock gardens, crevices, and drained or dry soils.
It can be combined with many sun-loving drought tolerant perennials like Achillea 'Moonshine', Asclepias tuberosa, Calamintha, Callirhoe, Coreopsis, Dalea, Dianthus, Echinacea (with narrow leaves), Eryngium, Iberis, bearded Iris, Oenothera, other Penstemon, Rudbeckia missouriensis, Salvia, Thymus, Teucrium, Yucca and medium to smaller grasses like Koeleria, Sporobolus, Muhlenbergia, Stipa, Schizachyrium.
