    Comments about Crocus Perovskia 'Blue Spire':

    This is a fantastic plant! I've got a couple together in the poorest soil imaginable. A hot, dusty border, full-sun and chalky soil and they are flourishing. This is the third year for them and each year they've been great. Beautiful colour flowers, attractive leaves and give height to the border. I should have put in plant supports as they grew (prune back hard in spring) as once they've got the flowers, the stems do flop. But hard to sort that now they're attracting so many bees! Thoroughly recommend this plant - and I get flowers throughout July and all the way through well into autumn.

    Comments about Perovskia 'Blue Spire':

    perovskia takes quite a long time to get going. It's a late summer bloomer but when it does start flowering it goes on and on for months. These specimens were quite small and took their time to bulk up but did eventually overtake the ones I bought from a garden centre that were larger, and these flowered for longer.

    Comments about Perovskia 'Blue Spire':

    purchased new plant in March, very slow to start and come up, flower display only average, very floppy, needs staking. I had bought this to go with the gaura but would have been disappointed with the display had I not had the chocolate cosmos to go with it.

      Comments about Perovskia 'Blue Spire':

      I needed a large perennial for a hot sunny spot,that would go well with Mediterranean plants near a terrace in a blue, white and pale pink colour scheme. I planted these in a row in a raised bed was able to have some exposure to wind. From late May onwards they gave us fabulous pale purple display about 3 feet high and I have not cut them back. They are still, in mid December, providing our use as a lovely serial screen of pale grey stems and branchlets, spectacular in the few frosts we've had.as we had a fairly hostile April in this region they were slow in getting going, but that is the only negative. I would recommend giving these plenty of room to show their full glory.

        • Q:

          Hi, I have a 'Blue Spire' plant that is in need of help! It has 3 branches, each is bare for about 6 inches from the soil up, after that it's bushy, leafy and covered in flowers. Sadly, it looks ridiculous because of the naked bottom (so to speak). Is there anything I can do to encourage new branches from the base or is it a lost cause?

            A:

            Hello,

            Perovskias do have the tendency to become leggy, so we recommend giving the a hard prune, each year in mid-spring, just as the new growth is starting to emerge. If you have not done this previously, then you should cut back all the stems to approximately 5 - 10cm above ground level. In subsequent years, you can then cut the stems back again to within 3 or 4 buds from the old wood.

        • Q:

          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
