Penstemon

Penstemon is a genus of flowering plants known for their tubular, brightly colored flowers and adaptability to dry, rocky environments, including deserts. With over 250 species native to North America, Penstemons are a staple in wildflower displays and xeriscape gardens.

Key Features:

• Flowers:
  The flowers are tubular or bell-shaped, typically with five lobes, and come in a wide range of colors—red, pink, purple, blue, and white are common. They often appear in vertical clusters on tall spikes above the foliage.

• Blooming Season:
  Most species bloom from late spring to early summer, although timing may vary based on location and rainfall.

• Leaves:
  Generally narrow, lance-shaped, and arranged oppositely along the stems. Some species have smooth leaves, while others may have a slightly fuzzy texture.

• Size:
  Penstemons vary in size, from small ground covers to tall, upright plants reaching 1 to 4 feet in height.

• Habitat:
  Found in arid to semi-arid regions, including deserts, foothills, and alpine zones. Many species thrive in well-drained, rocky soils and full sun.

• Pollinators:
  Especially attractive to hummingbirds, bees, and butterflies, thanks to their tubular shape and vivid colors.
