OVERVIEW
About This Plant
Beardtongues (penstemons) are a standout choice when you want a plant that looks great and is easy to include in a pollinator-friendly space. Their tubular flowers are made for sipping, and the plants often form neat clumps that fit well in borders, school gardens, and containers.
If you’re new to growing beardtongues, focus on two basics: sun and drainage. A bright spot helps the plant bloom well, and well-drained soil helps prevent the most common problems. In containers, always use a pot with drainage holes and avoid letting water sit in a saucer.
For a bigger visual and pollinator-friendly impact, plant a small group together rather than a single plant tucked away. Then keep care simple: water while it’s establishing, trim spent blooms if you want a tidier look, and skip pesticides—small patches of leaf damage are normal in a living garden.
Best role for pollinators
Sunny beds, borders, and containers where you want long-lasting color and pollinator-friendly blooms

SUMMARY
If You Remember Three Things
A quick scan of what they do, what they need, and the best first step.
What they need
Sun and good drainage are the big keys; steady care while establishing, then lighter watering.
One best action
Choose a spot (or pot) with excellent drainage and plant in a small group for a bigger impact.
IMPACT
Why Plant This?
In a city like Toronto, even small plantings can add up. Beardtongues are a practical way to add pollinator-friendly flowers to a yard, school garden, or balcony container—especially when you focus on sun, drainage, and pesticide-free care.
The name “beardtongue” comes from a fuzzy, tongue-like structure inside many Penstemon flowers.
Key Impacts
What it Supports
- A single flowering plant in a pot can be a helpful stop for pollinators in a city.
- Tubular flowers can be especially useful for pollinators that prefer deeper blooms.
- Perennial clumps can return year after year, making it easier to build a reliable flower patch over time.
RECOGNITION
Identification Guide
Use these quick clues to recognize beardtongues in the garden:
Leaves
Often lance-shaped to oval, usually in a basal clump with additional leaves along the stems; texture and color vary by species.
Flowers
Tubular, two-lipped blooms held in clusters; colors vary widely by species and selection.
Fruits
After flowering, plants form small seed capsules that can be left to mature if you want to try natural reseeding.
LOCATION
Where It Grows
Native environments and the best spots to place it in your landscape.
Habitats
- Open, sunny slopes
- Well-drained upland areas
- Rocky or gravelly soils (varies by species)
Where it is often used
- Pollinator-friendly container planting
- Sunny border or front-of-bed color
- Rock-garden style plantings where drainage is excellent
- Mixed wildflower beds for season-long blooms
SEASONALITY
When It Blooms
Notes on bloom windows and how this plant helps pollinators across the seasons.
Bloom window
Bloom timing depends on the species and the growing conditions, but many beardtongues flower from late spring into summer.
Bloom Season Role: A bright, nectar-friendly bloom that can help fill the mid-season gap in many gardens.
Seasonal benefits
- Adds a strong burst of color when many gardens shift from spring to summer
- Provides repeat interest if spent blooms are trimmed
- Works well as a “bridge” plant between early and late bloomers
REQUIREMENTS
What It Needs
The right mix of sun, soil, and space for healthy growth.
Sun exposure
Choose a bright spot with plenty of sun; part sun can work, but flowering may be lighter.
Soil type
Well-drained soil is essential. If your soil stays wet, consider a raised bed or a container with drainage holes.
Moisture needs
Water regularly while the plant is settling in. After that, water when the top layer of soil dries—avoid keeping it constantly damp.
Planting method
Plant in spring or early fall when conditions are mild. Space plants so air can move between them.
Mulching tips
Use a light mulch (or gravel mulch) to reduce weeds without trapping too much moisture around the crown.
GARDENING GUIDE
How to Grow It
Simple steps to plant, prune, and maintain healthy trees without pesticides.
Planting tips
- Pick a sunny spot (or a pot) with excellent drainage.
- Loosen the soil and mix in grit or coarse material if drainage is slow.
- Plant at the same depth as in the nursery pot; don’t bury the crown.
- Water in well, then let the soil dry slightly between waterings.
- Add a light mulch and keep weeds down while the plant establishes.
Seasonal care
- Deadhead (trim off spent blooms) to keep the plant tidy and encourage more flowering on some types.
- Avoid overwatering—especially in cooler or rainy periods.
- Leave some seed heads late in the season if you want natural reseeding or winter interest.
- Cut back old stems when new growth starts, rather than rushing to tidy too early.
What not to do
- Planting in a spot that stays wet after rain
- Watering on a schedule instead of checking the soil
- Using pesticides to deal with minor leaf damage
- Cutting everything back too early in the season
Pairings
Best Pairings for Season-Long Bloom
Pairing ideas to keep pollinators fed throughout the growing season.
Early Bloom
- Early-blooming native wildflowers suited to your site
- Spring bulbs in nearby areas (where appropriate)
Mid-Season Bloom
- Other sun-loving wildflowers with similar drainage needs
- Low grasses or grass-like plants for contrast
Late-Season Bloom
- Late-summer and fall bloomers to extend the flower season
- Seed-head plants that add texture after flowering
