Buy Perovskia 'Blue Spire' Russian sage ( syn. Salvia Blue Spire ): Violet-blue flowers and silvery foliage. Great planted en masse

This shrub is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring.

  • Position: full sun
  • Soil: well-drained, poor to moderately fertile
  • Rate of growth: average
  • Flowering period: August to September
  • Hardiness: fully hardy

    With its aromatic leaves and upright spikes of violet-blue flowers, Russian sage makes a wonderful companion to all kinds of late-summer ornamental grasses and perennials. In August and September, tiny, violet-blue, tubular flowers appear on silver-grey spikes above the main framework of the plant, among deeply-cut and lobed, grey-green leaves. This deciduous sub-shrub makes a real impact planted en masse alongside a path, where the sage-like fragrance of its leaves can be appreciated, or try it alongside other silver-leaved plants, or in swathes in a sunny border. One of our recommended plants, it copes well with dry, chalky soil and salt-laden air.

  • Garden care: As this shrub has a tendency to flop a little, in March cut back to the permanent framework of the shrub to promote bushier growth. After pruning apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant.

Planted in a South facing collection of containers, this plant has thrived. 2 seasons of pleasure. Can't say more.

A lovely health plant


this plant has been put in our front border to complement other plants




Satisfied customer


I first saw this plant when I visited an "Open Garden" so made a note of the name and then looked online to find a supplier. I am very pleased with the plant, it took a short while to establish but once it got going it flowered very well. I am looking forward to it being even better next year. I was very impressed with the packaging and delivery.

Used in a border however did not mature as fast as expected so was small.

I saw the combination of the Silver Ghost with Perovskia Blue Spire. They do look great together. Healthy plants which are still going. Which for me - is somewhat a miracle.




Lovely plant, securely boxed and delivered quickly.


Really good service, I will reuse Crocus!

I planted my perovskia 9cm pots back in April, at the back of a new border in full sun but relatively fertile ground (clay, but reasonably well draining). They got the full May bucket of water, but were not waterlogged for a particularly long time. None of them seem to have grown more than an inch and are being rapidly out-grown by my new front of border plants. Should I be expecting some growth by now?!


Yes I would expect to see some growth on these plants, particularly as the weather has improved in recent weeks. Feel free to get in touch with us at with your order number, photos of the plant and mention you've posted a review here too, thank you.


I have received delivery of my order of perovskia in 9cm pots but assume I am not meant to plant them out until the spring? I intend to repot them into larger pots. Do I then keep them in the green house and if so do I need to keep it heated?


These plants are fully hardy, so provided your soil is not waterlogged or frozen, they should be planted straight out in the border.


My mother got exited with the pruning and by the end of September, to my horror, she cut back all my Perovskias almost to the ground! Is there a chance they will grow back or have they been killed?


Ideally these plants should be cutback in spring, however it's not possible for me to tell if they will have been killed. by their autumn trim. With that in mind, I would just keep an eye on them and keep my fingers crossed. I also wouldn't give up on them too early either, as it is often late May or even June before they start to put on new growth.


I have a group of Perovskia Blue Spire plants in a sunny gravel garden. They flowered well last summer and are now just silver stems with no sign yet of any new growth. when should I expect new green growth to start appearing? In the meantime I have not pruned any of the silver stems as I do not know if they should be cut down?


Hello there In the spring, say about March I would cut the plants back to a framework approx 30-45cm above ground. This will help to encourage bushier growth. As these are later flowering plants they can be quite late to show any new shoots.

All my Perovskia stems have turned silver during the winter, and there is no new growth coming through yet. I have not cut any stems down. When should I expect new growth?


Hello, These are late-summer flowering, so I would not expect them to be showing any signs of life for another couple of months. You shoud however cut them back in March.


Any reason why myplants are not flowering? Hello. I have some plants that seem to be happy and growing well but aren't flowering- two Fuchsias, a Crambe cordiflora, and a Geranium 'Buxton's blue'. Even those that are flowering are a bit rubbish - a Perovskia 'Blue Spire' and some Verbena bonariensis have produced some flowers but not many. What can I do to improve flowering - is there a particular feed or fertiliser I should use? The soil is dense london clay, but the garden is not shady, but nor is it in full sun. It is quite sheltered. Many thanks, Robert

Hello There, There are a number of reasons why plants don't flower including too much shade, not enough water or nutrients, or pruning at the wrong time of the year. It can also be caused by the plant putting on new root growth instead of focusing its energies on producing flowers. I am not really sure why yours has not produced buds, but you can often give them a bit of a push by feeding with a high potash fertiliser. I hope this helps. Helen Plant Doctor
