Flower Colour (?):

What does this mean?

Flower Colour

Flowers come in a vast variety of colours from pure white to almost black. Colour can be affected by a number of factors including environment and diet. Use the photographs as a guide and expect variations.

Orange
Flowering Time (?):

What does this mean?

Flowering Time

A plants development is synchronised with the changing seasons and flowering is one of several changes that occur at the appropriate time of year dependent on the specific plant. While our meteorological seasons are defined by specific dates; there can be two or the weeks difference in the start and end of the horticultural 'season' between the north and south of the UK.

Summer - Autumn
Foliage (?):

What does this mean?

Evergreen

Plants that have leaves all year round are classified as evergreen. They can however lose leaves sporadically throughout the year.

Deciduous

Deciduous plants drop their leaves in autumn, look bare in winter and put out new leaves again in spring. Some plants such a Beech retain their dead leaves until the new spring growth.

Semi-evergreen

There are exceptions, some plant drop their leaves in cold winters but keep them if it is mild. These are classified as Semi-evergreen.

Deciduous
Fragrant (?):

What does this mean?
Fragrant
For plants that are fragrant the level of fragrance may vary, results may improve by planting in larger blocks. The fragrance may come from flowers or foliage.

No
Growth Rate (?):

What does this mean?

Growth rate of a plant will determine how fast the plant reaches it ultimate height and is affected by four main factors: temperature, nutrients, light, and water.

Average
Hardiness (?):

What does this mean?

Fully Hardy

Hardy in most places throughout the UK even in severe winters (to -15)

Half Hardy

Hardy throughout most of the UK (to -10)

Frost Hardy

Hardy in coastal and relatively mild parts of UK (to -5)

Fully Hardy
Position (?):

What does this mean?

Full Sun

Six or more full hours of direct sunlight but don't forget to water.

Partial Shade

Two or three hours either in early morning or late evening sun. Very limited exposure to midday sun.

Dense Shade

Usually no more than two hours direct sunlight. Usually under dense trees, shurbs or in shade cast by buildings/fences etc.

Full sun, Partial shade
Soil Moisture (?):

What does this mean?

Well Drained

Well-drained soil allows water to percolate through reasonably quickly without pooling. Well drained soil can often be dry and lack nutrients.

Poorly Drained

Poorly Drained soil is usually saturated periodically during the growing season and remains wet for several days at a time. Saturated soil can deprive roots of oxygen.

Moist Well Drained

A moist well drained soil is the best of both worlds by combining high permeability with the ability to retain moisture. Adding well rotted organic matter to dry or wet soil will help improve both these characteristics.

Moist Well-drained
Soil PH (?):

What does this mean?

Acid

Soil with a pH between 1 and 7 is classed as acid, ericaceous plants such as Rhododendrons need acid soil.

Neutral

A neutral pH which is around 7, will be suitable for most plants. Clay soils tend to be neutral.

Alkaline

Soil with a pH between 7 and 14 are refereed to as Alkaline. Chalky soil is usually Alkaline.

Acid, Neutral, Alkaline
Soil Type (?):

What does this mean?

Chalk

Chalky or lime-rich soils may be light or heavy, largely made up of calcium carbonate and are very alkaline.

Clay

Clay soils are potentially fertile and hold a high proportion of water. They drain slowly and take longer to warm up in spring.

Loam

Loam soils are s mixture of clay, sand and silt that avoid the extremes of clay or sandy soils. Fertile, well-drained and easily worked.

Sand

Sandy soils have a low clay content, drain quickly, easy to cultivate and work. They can dry out quickly and are low in plant nutrients. Often very acidic.

Glowing Orange Blooms with a Sweet Scent

‘Prince of Orange’ produces large, dome-shaped flower clusters in vivid orange hues, with subtle coral and salmon undertones that intensify in evening light. The starry flowers are lightly fragrant, making them a delight near seating areas or garden paths. Flowering through the heart of summer, they add bold, warm colour just as earlier blooms begin to fade.

Perfect for Borders and Cottage Gardens

With its upright habit and generous flowering, this phlox is ideal for the middle or back of mixed borders. It blends beautifully into classic cottage garden schemes, prairie-style planting, or more formal arrangements. It also makes a striking contrast when paired with cool purples, blues, or silvers in summer borders.

Long-Lasting Colour and Excellent for Cutting

The vibrant blooms of ‘Prince of Orange’ are long-lasting in both the garden and the vase. Regular deadheading encourages a prolonged flowering period, often well into early autumn. Cut stems for bold, fragrant arrangements to bring a splash of colour indoors.

Growing Tips

Watering: Keep soil moist during dry spells, particularly when the plant is in flower.
Feeding: Apply a balanced fertiliser in spring and mulch with compost or well-rotted manure to support strong growth.
Pruning: Deadhead regularly to extend flowering. Cut back stems to ground level in late autumn.
Dividing: Divide large clumps every 3–4 years in early spring or autumn to maintain vigour.
Positioning: Best in full sun but will tolerate light shade, particularly in warmer areas.

Fully Hardy and Reliable

Phlox ‘Prince of Orange’ is fully hardy throughout the UK and thrives in a wide range of garden soils, as long as they are not too dry or poorly drained. It returns reliably each year, forming a sturdy clump that expands gradually over time.

Perfect Companions

Pair Phlox ‘Prince of Orange’ with:

Salvia nemorosa ‘Caradonna’ – for deep purple contrast
Achillea ‘Terracotta’ – for a warm, sunset-themed palette
Veronicastrum virginicum – for upright structure and soft lilac blooms
Perovskia ‘Blue Spire’ – for a silver-blue haze against the orange tones

Buying Perennials from Jacksons Nurseries

At Jacksons Nurseries we lightly trim back our perennials after flowering and trim them back at the end of the season to ensure that the plants remain neat and tidy whilst in the pot. The more tender the plant the less we cut back to help protect exposed stems from winter frost. Depending on the plant variety we will then prune back further in spring once the risk of the more severe frosts is over.

As a result, depending on the time of year you buy perennials, they may not look like images showing their ‘prime time’ in flower and looking at their best.

From late autumn onwards and dependent on variety, there may be very little visible above the soil except for a few cut back dormant leaves or stems. It is perfectly normal for dormant plants to look like this from autumn onwards, they will however burst back into life in spring.

Availability: Stock availability figures are provided as a guide only. There is a delay between orders being placed and the plants being gathered by our pulling team. During this time it may be possible for a member of the public to purchase these plants from our Garden Centre, while this is rare it is a possibility and we will notify you of any problems as soon as possible. This figure may also include plants that have not yet be flagged as unsaleable.

Pre-order: Pre-order times are given as a guide only and may vary dependent on the growing season. Orders containing Pre-ordered products will be shipped as a single order when all items become available. Large orders may be part shipped, please contact us on 01782 502741 or email sales@jacksonsnurseries.co.uk.

Perennials are described and classified differently by different gardeners but all would agree that they are plants that come into flower every year from early spring to late summer, the exact time dependent on variety and most die back to ground level in autumn and winter.

As for all plants, soil preparation is time well spent. Dig over the area to be planted ensuring that the ground is free draining. If not then you may wish to either consider planting in a different spot or raising the level of the planting area by adding additional topsoil, well rotted garden compost and/or well rotted manure. Add ‘Fish, Blood and Bone’ fertiliser or a high potash fertiliser to encourage good root growth and development.

It’s always a good idea to plant a few of the same plant together, we recommend planting in 3’s or 5’s to provide a bold effect but allowing them plenty of room to develop.

Always check eventual plant heights when planning borders to ensure that the taller plants are at the back (or at the centre of an island bed) followed by the medium and then smaller low growing plants.

Remember to deadhead perennials after flowering, trim back lightly in autumn as required to tidy the border and if necessary trim again in spring once the risk of heavy frost has passed.

If perennials get too big, start to flower less and less or if it seems to be dying off from the centre, consider dividing the plant but always check that the particular variety is happy to be divided and that you divide at the right time of year for the plant.

By using this simple guide and a little time, perennials can make an absolutely spectacular difference to your garden.
