  • Position: full sun
  • Soil: fertile, well-drained, neutral to alkaline soil
  • Rate of growth: vigorous
  • Flowering period: April to June
  • Hardiness: frost hardy (needs winter protection in cold areas)

    In mid-spring, this spreading, evergreen shrub is an arresting sight, smothered in dense clusters of dark blue flowers. It makes a superb specimen plant for a south or west-facing border among spring-flowering bulbs, and when has finished flowering, provides an excellent foil for later-flowering deciduous shrubs and perennials. It needs a protected site, as the deeply veined, dark green leaves are easily scorched by cold, drying winds.

  • Garden care: Each year after the plant has flowered reduce the shoots by one third and apply a 5-7cm (2-3in) mulch of well-rotted organic matter around the base of the plant.

      When is the best time for planting this shrub I need it to cover a fence at the top of my garden

        Hello there
        As a general rule plants that are grown in containers can be planted at any time of year as long as the soil isn't frozen solid. The best time to plant is in the autumn when the soil is still warm enough to encourage root growth but the plant isn't in active growth, or the spring before the temperatures.
        However as Ceanothus are not fully hardy I would wait until the spring now, unless you live in a warm part of the country, with a sheltered garden and are able to protect the plant from cold weather.
        Hope this helps.

    • Q:

      I have a west facing very brick wall with trellis on top as the garden boundary. (13meters long) I would like some evergreen climbers provide some colour and act as privacy hedge that grow to 2 to 2.5m high. I heard that Ceanothus can be trained to grow as climbers. Could you please advise on which variety of Ceanothus would work best? and also which other climbers would mix well with Ceanothus?
      Thank you,

      There is a lot of dead growth at lower part of my ceanothus puget - the flowering branches are al to the top rear of the schrub - should I prune all the dead areas now or wait until flowering has dies away? Thank you

        Ideally any pruning should be tackled after flowering in midsummer, but if the lower growth is completely dead, then it can be removed at any time of the year. These plants flower on the current seasons growth, so to keep them looking their best, you should reduce the shoots that have flowered by one third. This will encourage fresh new growth. It is worth keeping in mind though, that these plants tend to be relatively short-lived, so if it starts to look old and woody after 10 years or so, it may be better to replace it.

      Asked on 7/4/2010 by Linda Binfield

      • A:

        Hello Linda, The most likely cause of these black spots is Fungal Leaf Spot. This can be caused by a number of things, but is usually a result of the plant being stressed in some way. It may be that it was slightly too cold in winter, or if it is in a pot it may need to be moved to a larger one, or planted out into the ground. Keep an eye on the watering and try to improve the general growing conditions and you should start to see new growth. If the black spots are really unsightly, you should pick off the affected leaves (being careful not to defoliate it completely) and give it a feed with a general purpose fertiliser like Growmore. I hope this helps. Helen Plant Doctor

      Ceonothus 'caught' by cold weather....

      Hi, I wonder if you could help me! I have a large, established low-growing Ceanothus that has never had a problem with the cold weather before, but this year's snow has caused most of the usually evergreen foliage to turn brown and take a turn for the worse. There is still some foliage towards the bottom of the plant that's still green. Do I leave it be, trim it back or has it died? Many thanks, Gareth

      • A:

        Hello Gareth, Ceanothus are not fully hardy, and they are quite short-lived too, so they usually only last around 6 - 8 years. Therefore I suspect that the combination of old age and freezing temps have taken their toll and it is time to replace it. I'm sorry not to be more help. Helen Plant Doctor

      Growing plants for a wedding

      Dear Crocus, I am a very happy customer ..... I love your site, plants and service. I learnt about you first from Arabella Lennox-Boyd. But now I am writing for some advice please. My sister is getting married in Oxfordshire on the last weekend of May. I would love to grow the flowers for the wedding. I have a big garden with empty beds and a green house at my disposal. Could you give me some advice on types of cut flowers that would be in bloom at the end of May? Some pointers as a place to start my research and buying would be fantastic. Thank you very much, Best wishes, Kate

      Clay loving evergreen plant for covering a wall

      Sir, I need to hide an ugly brick wall. I would prefer to have all year cover, meaning evergreen, and not over 6` or so tall, and able to thrive in my clay rich soil. I thought of a blue lilac but am not sure if the roots could cope. A variety of plants might look nice and would breakup the monotony of the wall, but your advice would be much appreciated. Sincerely, Dorothy.

      Specimen Ceanothus or another large bushy shrub....

      Good afternoon, When I was first looking for a Ceanothus to replace the one we have in our front garden, I looked on your website, but you only had small ones. Our once lovely Ceanothus has been pruned out of all recognition again this year, as I planted it a bit too near our boundary when it was a baby. I know it may come back, but it is getting ridiculous as every time it grows back it has to be cut back again severely and then ooks a mess for most of the year. Have you got a nice, tall, bushy Ceanothus to replace it? I love my Ceanothus but perhaps if you don't have a big one, do you have another large, flowering shrub as an alternative? Hope you can help Regards Margaret

      • A:

        Hello Margaret, it is rare to find larger sized Ceanothus as they are usually quite short-lived and don't normally live longer than 6 - 8 years. We do have a selection of larger shrubs on our site like Hamamelis, Hydrangeas, Magnolias, Acer, Cornus, Cotinus, Philadelphus, Syringa and Viburnum, so you may find something of interest. They will be listed in this section. http://www.crocus.co.uk/plants/ I hope this helps. Helen Plant Doctor

    • Q:

      Which Ceanothus - Puget Blue,Concha or Autumnal Blue?

      Hello, I would like to plant 5 Ceanothus along the edge of my patio in large concrete rings. I was hoping that the Ceanothus would quickly grow to form a cascading effect between the concrete rings, can you advise me which variety would be best and what soil to fill the tubs with, thank you, sincerely, Paula
      Asked on 4/7/2009 by Paula O'Dwyer

      • A:

        Hello Paula, All of the Ceanothus you have listed are upright and shrubby, so if you want to create a cascading look then the best option would be Ceanothus thyrsiflorus repens, which will tumble over the edges of the rings.

      • A:

        Hello David, Iris are certainly lovely plants, however the rhizomatous types do not have a particularly long flowering period. With the exception of the unguiculares, which flower from autumn to spring, most of them will flower from mid- to late spring. The later ones include those from the arilbred, spuria or louisiana groups. Most of the bulbous types will flower in winter or early spring. I hope this helps. Helen Plant Doctor
