- Position: full sun or partial shade
- Soil: fertile, well-drained soil
- Rate of growth: fast-growing
- Flowering period: June and July
- Hardiness: fully hardy
In June and July this lovely deciduous shrub is smothered with highly fragrant, double, pure white flowers among dark green leaves that turn yellow in autumn. This tall, vigorous variety of mock orange looks wonderful towards the back of a mixed or shrub border, where on warm summer evenings, the delicate, orange-blossom fragrance floats on the breeze. It is a magnet for bees and can also cope with urban pollution and salt-laden air.
- Garden care: Mulch around the roots in spring with a deep layer of well-rotted garden compost or manure. Prune in late summer, immediately after flowering, removing one in four of the older stems to ground level.

Q: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 MargaretAsked on 5/12/2009 by D DRAKETT
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 DoctorAnswered on 8/12/2009 by Crocus Helpdesk
Q:Plant help with Camellia pruning, bugs on our Acer, Cornus not growing and our Philadelphus still not flowering!
I have some queries regarding a few plants purchased from Crocus which I'm hoping you can help me with. This year we purchased "Camellia ?? williamsii 'Debbie'" and it seems to be growing nicely already, however it's very straggly, it arrived with two stems tied to a cane. The stems have continues to grow, and it's now tied to a longer cane, but it's showing no signs of bushing out. Will it do this with more time or do we need to start pruning to encourage it? We also bought "Cornus alba 'Sibirica'(red-barked dogwood)" and have it in a nice sunny position. It's lost its leaves for the winter and the stems are lovely, but it hasn't grown at all since we bought it (in June). Is this normal or do I need to do anything specific to help it along? We bought a Japanese Maple "(Acer palmatum var. dissectum Atropurpureum Group)" a few years ago but has recently become infested with some kind of beetle. We didn't notice anything, until we were moving the tub at the weekend and found the tree, soil and side of the pot coated in little grey/brown beetles slightly bigger than aphids. I've sprayed it with a pesticide which seems to have killed them, but I'm wondering what they were and what if anything can be done to ensure they don't come back, preferably without having to keep coating it with pesticides. Finally, we also bought a Mock Orange (Philadelphus Manteau d'Hermine). We originally had it in a tub, where it grew at an enormous rate, but it had no flowers. This year it seemed to be pot-bound, so we transplanted it into the garden, in a nice sunny position. It has continued to grow in both width and height, but to date has still had no flowers. Any suggestions? Thanks MarkAsked on 21/10/2009 by Anonymous
A:Hello Mark, Young Camellias can be very variable in shape, and some pruning is often needed to encourage a balanced, bushy shape. If yours is long and thin, then you can encourage it to bush out by pinching out the growing tips and shorten over-long stems. Ideally this should be done in spring, after it has finished flowering but before the leaf buds break. As for the Cornus, it may simply be concentrating on putting on new root growth rather than top growth, or perhaps you have very heavy soil, which will slow growth down. You should not really be feeding many plants at this time of the year as you can do more harm than good by encouraging new growth at this time of the year. I would however expect to see some signs of growth in spring next year, at which point you can start feeding again. I am not really sure what insects you found on your Acer, but it may have been woodlice. These are completely harmless, but they do eat decaying organic matter such as leaves etc and they do like cool, damp spots to hide out in. Finally, 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. 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 during the growing season. I hope this helps.

Q:My Philadelphus doesn't flower
Please could you offer some advice. Last year we bought two Philadelphus plants. We planted one in the tiny back garden and one in the front garden and both have grown quite vigorously. Our problem is that they have not flowered and still show no signs of doing so. Is there anything I can do to encourage flowering? Lynda and ArthurAsked on 22/6/2009 by Lynda Styles
A: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, which is quite common for things that have recenlty been planted. 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.
