Volcano phlox produce masses of large flower clusters over an extended flowering season, creating a dazzling display throughout the summer months. Their sturdy, well-branched growth habit ensures the plants remain attractive while supporting an abundance of blooms, making them equally suited to garden beds, borders and decorative containers.

The fragrant blooms are also highly attractive to bees, butterflies and other beneficial pollinators, adding life and movement to the garden while supporting biodiversity.

Award Winning Plant

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

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 them 30cm-40cm (12-16") apart to boost air circulation.

WAYS TO USE THEM

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.

SHAPE & SIZE

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

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

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.
