Sumptuous, large, deep purple flowers with greenish centres from mid-summer to early autumn. This large-flowered clematis can be relied upon to produce a mass of velvety blooms with either 4, 5 or 6 petals from June to September. Ideal for growing in a large container, supported by trellis or garden canes, it copes well in a north-facing site.
- Garden care: In early spring cut back the previous year's stems to a pair of strong buds about 15-20cm (6-8in) above ground-level and apply a slow-release balanced fertiliser and a mulch of well-rotted garden compost around the plant, avoiding the immediate crown.

Q:Climbers for trellis with wildlife considerations
Hi I have a bare trellis at the end of my garden which marks the end of my raspberry and rhubarb beds, and where my composting and comfrey live. I want to cover this trellis with something to give colour all the year round, even if that "colour" is green leaves. I also want to provide something beneficial to the wildlife. I had thought about growing an Ivy, with a Clematis. Would these two climbers work in a small area and would I get my combination of colour, all year interest and wildlife benefits? Thanks MikeAsked on 17/3/2010 by Mike Simpson
A:Hello Mike, The best climbers for wildlife are Hederas (Ivy) or Lonicera (Honeysuckles). These are both pretty big and vigorous plants though and your trellis sounds quite small. The ivy can be cut back very hard though, so perhaps your best option would be to use an ivy and then plant a smaller growing group 3 Clematis, which should be cut in early spring each year. I hope this helps. Helen Plant DoctorAnswered on 17/3/2010 by Crocus Helpdesk
Q:Can I use weedkiller in the border?
Is it okay to use products like 'Roundup' in a flower bed or am I at risk of damaging the plants I want to keep as well as the weeds?Asked on 19/3/2005 by Ellen Hesketh
A:Most weedkillers like Roundup' are indiscriminant, so they will kill off anything they come into contact with. Therefore, you need to be extremely careful when applying them, and try to isolate the plants you want to kill off. Sometimes you can do this using cardboard sheeting, but make sure you spray it on a calm day so the spray does not drift in the wind. Alternatively, I would suggest you remove the weeds by hand or hoe.Answered on 21/3/2005 by Crocus
