Phlox paniculata 'David'
A very vigorous new white, with mounds of scented flowers - already a border star in America - and it shrugs off mildew
- Position: full sun or partial shade
- Soil: fertile, moist soil
- Rate of growth: average
- Flowering period: July to November
- Hardiness: fully hardy
Phlox have always been country garden favourites for their delicious scent and attraction to butterflies and bees. This new variety has gorgeous trusses of hydrangea-like, pure white flowers which appear from July to November above dark green leaves. It is a showy perennial that forms a natural mound and looks wonderful planted near patios or paths where the scent of the flowers can be fully appreciated. It will tolerate full sun or partial shade, but like all phlox, does not like soil that dries out in summer. This vigorous variety has good resistance to powdery mildew too.
- 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.

Many flowering plants can be encouraged to produce better and longer-lasting displays with the minimum of effort. A plant produces flowers in order to reproduce and ensure the survival of the species. Once a plant has flowered and fertilisation has takenRead 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
