Autumn Amethyst is the perfect plant for any purple lover. After a brief rest, the plant blooms again throughout summer and autumn. Its purple beauty is not over. Throughout winter, it continues to bloom in evergreen leaves that turn a rich bronzy violet color when temperatures drop. You can place it alone or in a group near a window, or along a walkway. Its small size and extreme cold tolerance make it a great choice for containers. It looks great in containers with black, white, or gray borders.

How to Grow Autumn Amethyst

Plant them in either sun or shade. Its soft color allows it to blend well with other plants that are in partial sun or dappled sun. You can play up the purple color by pairing it with hostas in white or purple. hydrangeas, ferns, and hydrangeas are also great companions. Pair it with spring-blooming peonies and iris for sunnier areas. You can then pair it with coneflowers, daylilies, coneflowers, and phlox later in the season to complement its lavender flowers.

General Care Guide for Autumn Amethyst


They don’t like soil that is too wet. Dig the planting hole so it is at least twice as large and not deeper than the root ball. The backfill soil that is average in quality should be sufficient. 


After planting, water the well and keep it hydrated throughout the growing process. It is important to keep an eye on the plant during dry spells. If there is not enough rainfall, water it. 

Pruning and Maintenance

Protect the base of the plant from weeds by applying light mulch. After spring blooming, you can start trimming them. To enhance blooming, apply granular fertilizer to acid-loving plants early in the spring.


Autumn Amethyst is an upright mounding shrub, measuring 4×4 feet in stature and habit, and can be planted almost anywhere. It should be planted alone at 2.5 feet from all sides. This will allow it to spread out and fill in. These shrubs can be planted in a large area, which is useful for foundation plantings under windows or mature trees. You can space them a bit tighter, at 2 feet from the center. Container plantings require a minimum 16-inch opening and a capacity of several gallons. To prevent it from tipping over if the container is very light, anchor it using bricks or stones at the bottom.

Hello, I’m Pete and I’m currently based in the west of Scotland, in a small place called Rosneath, where I’m exploring my garden adventures. I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
