What penstemons need

What they need and which plants grow well with them

THEY NEED

At least six hours of sun daily.

Good air circulation.

Soil that is well drained and relatively low in organic matter.

To encourage plants in containers to establish in garden soil, remove most of the soil mix from around the rootballs of plants before setting them in the ground.

Little competition from neighboring plants.

Irrigation/rain before bloom, dry conditions thereafter.

Prompt removal of spent flower stalks to prevent energy-robbing seed formation.

Shrubby evergreen species need protection from drying winter winds.
