Water Saving Tip:

Replace turf with groundcovers, trees, and shrubs. If you have areas where no one uses the grass, patches that do not grow well, or a turf area too small to water without runoff, consider replacing the turf with water-efficient landscaping.

  • Description

  • Notes

Foxglove is a clump-forming biennial with tall spikes of tubular flowers blooming May and June. Plants grow about 2 to 3 feel tall and half as wide. The foliage grows in a clump at the base and is a soft green.
Foxglove need rich, amended soil that is very well draining. Wet soils are its death. Prefers part sun, with shade being provided during the hottest part of the day. Deadheading can encourage new flowering, though leaving flowers to go to seed may invite new plants for the following season. The basal foliage is practically evergreen, though it does get very tatty over winter and the worst leaves should be cut away as new growth comes on in the spring. Leaves are toxic if ingested. Though biennial, we've included this plant in the annuals listing as it is frequently used that way.
