Grand, Pacific, or Western Hound’s Tongue
- Monocots are a major lineage of flowering plants; see family for general characteristics
- Borage Family (Boraginaceae)
- Perennial herb
- Alternate (1 leaf at each junction with stem) and simple (not divided into leaflets)
- Broad and up to 8 in. long
- Clusters of flowers, pink in bud changing to blue
- Five fused petals with white appendages forming a central crown
- Ovary superior (above the attachment of other flower parts)
- Fruit is a set of 4 nutlets (a small, dry fruit that does not split open, derived from a multi-chambered ovary), though some may not develop
- Height can exceed 2 ft.
- Native to California
- Grows in woodlands and in shady areas in chaparral
- See Calflora for statewide observations of this plant
- Outside California, grows from British Columbia south into California
- Grows at elevations to 5,600 ft.
- Cynoglossum (sy-no-GLOS-sum) – from the Greek kynos, “dog,” and glossa, “tongue”
- grande (GRAN-dee) – from the Latin for “big” or “showy”
- Hound’s-tongue – for the shape of the large leaves
- Flowers change color, perhaps telling pollinators whether a specific flower is worth visiting for pollen and nectar
- Flowers from more than 70 plant families use color changes to direct pollinators; documented examples include forget-me-nots (Myosotis) and heliotrope (Heliotropium), also in the Borage family (Weiss 1991)
- Bees can see blue colors, but not reds (Riddle 2016)
- Immature pink flowers may signal to bees, “Not ready; move on”; the mature blue flowers, “Ready for pollination”; and the fading pink of the aging flowers, “I’m done; don’t bother”
- Bees perceive ultraviolet colors of the nectar appendages, which appear white to us (Breckling 2008)
- Nutlets have hooks (cf. velcro) that catch on passing animals to aid in dispersal
- Some Native people called this plant ‘coyote ears’ (Breckling 2008)
- May be confused with forget-me-nots (Myosotis species)
- Hound’s tongue has larger, wider leaves; its flower center is white
- Non-native forget-me-nots have much smaller, narrower leaves; their flower centers are yellow
- Found in woodlands, especially in dappled shade
- See iNaturalist for observations of this plant
- Flowers February – April
