FLOWERS & FOLIAGE FLOWERS & FOLIAGE

Phlox Volcano are tidy, with narrow pointed leaves. Each produces large multi-branched flower clusters, with around 125 softly fragrant flowers per stem. There are many different flower colours – even bicolours – blooming from early summer through to autumn if the old stems are cut back by a quarter after the first flush is finishing.

PLANTING TIPS PLANTING TIPS

Phlox perform best in sunny positions but they will tolerate some shade. They’re also fairly tolerant of a range of soils but thrive where the ground is well-worked and fertile. To avoid putting their tolerance to mildew to the test, plant Phlox Volcano 30cm-40cm (12-16") apart to boost air circulation.

Phlox are very useful plants in the garden. They look wonderful in massed wedges of colour where large areas need to be filled. They are a great way to add pops of colour to an existing planting scheme. Mixed with other warm-weather flowering favourites they give form, colour and fragrance to containers filled with summer arrangements.

Phlox Volcano produce branches from a central base point. Each branch is upright and is strong enough not to need staking. Once the plants reach maturity they will stand up to 80cm tall and around half a metre wide.

FOOD & WATER FOOD & WATER

One of the benefits of this summer plant is that it will tolerate moderately dry conditions, but it’s good to note that it performs best when well-irrigated. In spring, feed with a slow release balanced fertiliser.

PESTS & DISEASE PESTS & DISEASE

Phlox Volcano is very tolerant but not entirely impervious to mildew, so when you do water, use a soaker hose instead of overhead watering to side-step the risk. All phlox can be affected from time to time by spider mites and thrips.
