Phlox paniculata 'Blue Evening'
- Position: full sun or partial shade
- Soil: fertile, well-drained soil
- Rate of growth: average
- Flowering period: July to September
- Hardiness: fully hardy
Trusses of fragrant, lilac-coloured flowers, which appear bluer in the early evening light, form on top of the upright, leafy stems from midsummer, attracting many beneficial insects. Very effective when teamed up with rich plums, purples and silver.
- Garden care: Support with bamboo canes, brushwood or ring stakes before the flowers appear. Phlox are greedy plants, so apply a mulch 5-7cm (2-3 in) deep of well-rotted garden compost or manure in early spring. Shear off the spent flowers to prevent reseeding. If the leaves show signs of powdery mildew, cut down to the ground and dispose of the affected foliage, but do not compost it. Clear away the debris around the plant to reduce the chances of reinfection. Cut down to the ground in autumn. Lift and divide large clumps in autumn or spring.

Q:My Phlox and Bergamot leaves are browning
Hi there I have a Phlox and some Bergamot which I bought from you a while back and whilst it's growing really well, I am finding that the lower leaves on the Phlox are going brown then yellow. I've been taking them off but as it's happening all the the way up the plant, bit by bit, it's going to look quite bare soon! I wondered why they are going yellow, and what I could do about it please? More or less the same with the Bergamot except that the leaves are going brown around the edges. Should I be taking those off and is there anything I could do to prevent it? Many thanks and best wishes DebbieAsked on 6/16/2009 by Deborah Newbury
A:Hello Debbie, It is quite normal for the older leaves on herbaceous perennials to die off as they are putting on new growth, so I would not be too concerned. Towards the end of summer, they will die back completely and in spring next year the cycle will begin again. If the plants look really tatty, then just remove the older foliage. I hope this helps.

These lovely plants produce a succession of lily-like flowers each of which lasts for just one day. At first, this seems rather disappointing, but they are such bright, exotic flowers and produced in such profusion that this isn't actually a drawback. InRead full article
Many gardeners who are happy, even gung-ho, with the secateurs when pruning shrubs and climbers are surprisingly reluctant to take the shears to herbaceous perennials. Maybe this is because it just doesn't seem quite right to be cutting back all that newRead full article
In the third week of this month you can 'Chelsea chop' your summer-flowering perennials to delay their flowering times. Sedums can be cut back by two thirds to provide lusher foliage, but at the expense of flower.Read full article
