Flowers and Foliage
This pretty perennial produces a profusion of small, daisy-like flowers with white petals that gradually fade to pink, giving the impression of a multi-coloured display on one plant. The cheerful yellow centres add warmth and brightness. The fine, trailing stems are covered in small, mid-green leaves that form loose mats or tumble attractively over edges and walls.
Garden Uses
Erigeron karvinskianus is ideal for growing in cracks between paving, on walls, or in gravel gardens where it will happily self-seed and spread gently. It’s perfect for spilling over raised beds, steps, containers or stone walls, and its long flowering season makes it a valuable addition to relaxed, naturalistic planting schemes. It pairs beautifully with lavender, thyme, nepeta, and other sun-loving plants.

A magnet for bees, butterflies, and other pollinators, this plant provides a valuable source of nectar across the summer months. Its informal, spreading habit also offers shelter to small garden insects, adding ecological value to borders and hard landscaping.

Buying Alpines from Jacksons Nurseries
At Jacksons Nurseries we lightly trim back our alpines after flowering to ensure that the plants remain neat and tidy whilst in the pot. The more tender the plant the less we cut back to help protect exposed stems from winter frost. Depending on the plant variety we will then prune back further in spring once the risk of the more severe frosts is over.
As a result, depending on the time of year you buy alpines, they may not look like images showing their ‘prime time’ in flower and looking at their best.

From late autumn onwards and dependant on variety, there may be very little visible above the soil except for a few cut back dormant leaves or stems. It is perfectly normal for dormant plants to look like this from autumn onwards, they will however burst back into life in spring.
Alpines are a group of perennials that generally grow in rocky conditions at high altitudes.
As for all plants, soil preparation is time well spent. Dig over the area to be planted ensuring that the ground is free draining. If not then you may wish to either consider planting in a different spot or raising the level of the planting area by adding additional topsoil, well rotted garden compost and/or well rotted manure. Add ‘Fish, Blood and Bone’ fertiliser or a high potash fertiliser to encourage good root growth and development.
It’s always a good idea to plant a few of the same plant together, we recommend planting in 3’s or 5’s to provide a bold effect but allowing them plenty of room to develop.
By using this simple guide and a little time, alpines can make an absolutely spectacular difference to your garden.
