The forever plant (Sedum purpureum), also known as the “live forever,” is a showy evergreen plant of the Sedum genus, which is poisonous if ingested. This robust wildflower works well as a ground cover; the forever plant only grows to heights of 18 inches, with a 2-foot spread of coarse-toothed foliage. The plant produces clusters of pink or yellow blooms that rise above each terminal shoot. Forever plants thrive in USDA hardiness zones 5 through 9, preferring well-drained, sunny soil with a pH between 7.0 and 8.5.
Things You'll Need
- Soil testing kit
- Lime or peat moss
- Forever plant
- Soaker hose
Test the soil after choosing a planting location for the live forever plant. Soil pH test kits are available in nurseries or garden centers. If the results of the soil test do not meet the requirements of the forever plant, the soil will require amending.
Break up the soil using a pitchfork and add the necessary amendment. For a soil pH below 7.0, amend with lime. A soil pH above 8.5 will need peat moss. Add either the lime or the peat moss per label instructions.
Dig a hole for the forever plant that matches the depth of its root ball, and twice its width. Remove the live forever plant from its nursery container and place it in the center of the hole. Backfill and pat the soil down gently to remove air pockets.
Supply the forever plant with at least 1-inch of water per week for the first two weeks. Plants of the Sedum genus enjoy moist soil at a depth of 1-inch during this time. Once established, supplemental watering is only required during times of drought. A soaker hose will provide deep watering down to the roots of the plant better than a sprinkler.
Apply a 3 to 4-inch layer of mulch around the forever plant. Straw or bark chips should suffice. Mulching will help protect the roots during dormancy, help with water drainage, and also reduce weed growth around the plant.
