Bertram Anderson Hybrid Stonecrop

Sedum 'Bertram Anderson'

The Story

Plant Bio

Sprawling or trailing stonecrops are low-growing succulent perennials that form mats of colorful foliage, valued for their toughness and use in hot, dry locations like rock gardens and border edges.

'Bertram Anderson' is an RHS Award of Garden Merit winner, celebrated for its unique, smoky purple-gray foliage on arching stems. This beautiful foliage provides a perfect backdrop for the clusters of rich, rosy-pink flowers that appear in late summer.

Uses & Benefits:

Offers sophisticated color and texture with its dusky purple foliage and arching habit. It's perfect for softening the edges of stone walls or pathways and provides a beautiful color echo for other purple-toned plants.

Its drought tolerance and low-maintenance nature make it an ideal choice for xeriscaping, rock gardens, and containers. It forms a dense mat that can help suppress weeds.

The late-summer flowers provide a valuable nectar source for bees and butterflies, contributing to the health of local pollinator populations.

Planting

How to Grow

Choose a site in full sun for the best foliage color.
Ensure the soil is gritty, lean, and drains quickly.
Dig a hole just deep enough to accommodate the root ball.
Gently tease out the roots and place the plant in the hole.
Backfill with soil, firming it gently around the plant.
Water sparingly after planting and allow soil to dry between waterings.

Pro Tip

Give this plant a 'haircut' in late spring by trimming stems back by half to encourage a denser, less open habit.

Keep It Thriving

Care Guide

Do

Provide at least six hours of direct sunlight daily.
Plant in sharply drained soil, such as in a rock garden or on a slope.
Allow the plant to trail over rocks or the edge of a container.
Cut back old foliage in early spring.

Don't

Do not overwater or plant in wet, heavy soil.
Avoid rich soil and fertilizer, which can cause weak, floppy growth.
Don't plant in a shady location, as the foliage color will be poor.
Avoid burying the crown of the plant when planting.
