Flowers
The charming feature of 'Toparia' is its profusion of small, pure white flowers that appear in dense terminal spikes during the summer months. Each individual flower is tiny but they are produced in such abundance that the entire plant becomes smothered in white, creating a spectacular display that attracts bees, butterflies, and other beneficial pollinators. The flowers have the characteristic four-petalled Hebe form with prominent stamens, and their pure white colour provides excellent contrast against the dark green foliage.
Foliage
The plant forms dense mounds of small, oval leaves that are glossy dark green and closely packed along the stems. The foliage is evergreen, providing year-round garden structure and interest. The leaves are typically 1-2cm long, creating a fine-textured appearance that gives the plant its naturally topiary-like form. The dense branching habit creates perfect symmetrical mounds without any pruning required.
Growth Habit
'Toparia' is particularly noted for its naturally perfect, dome-shaped habit that forms symmetrical mounds without any intervention from the gardener. This unique characteristic makes it appear as though it has been carefully shaped by topiary shears, hence the cultivar name. The plant maintains its neat, compact form throughout the year, making it ideal for formal gardens and situations where controlled growth is essential.
Soil Requirements
For optimal growth, plant in well-draining, fertile soil with good organic content. Excellent drainage is important as waterlogged conditions, particularly in winter, can cause problems. Most garden soils are suitable provided they don't become waterlogged. Heavy clay soils benefit from organic matter incorporation and improved drainage, whilst very sandy soils should be enriched with compost.
Light Requirements
Best grown in full sun but tolerates partial shade reasonably well. Provide at least six hours of direct sunlight daily to maintain the compact form and prolific flowering. Full sun positions produce the most abundant white blooms whilst maintaining the naturally tight, dome-shaped growth habit that makes this variety so distinctive.
Watering Needs
Once established, demonstrates good drought tolerance but performs best with consistent moisture during dry spells, particularly in the first year after planting. Water deeply but infrequently rather than little and often. Avoid overwatering, especially during winter months when the plant's water requirements are minimal.
Planting
Plant from spring through early autumn, with spring planting providing optimal establishment time before winter. Space plants 40-50cm apart for individual specimens or closer for low hedging effects. Being reasonably hardy, it performs excellently in borders and can be successfully grown in containers, making it versatile for different garden situations.
Maintenance
Exceptionally low-maintenance due to its naturally perfect growth habit. No pruning is required to maintain shape, though light trimming immediately after flowering can be done if desired. Remove any damaged or dead growth in spring. The plant rarely needs dividing and established specimens can be left undisturbed for many years.
Feeding
Benefits from annual feeding in spring with a balanced fertiliser. Apply a slow-release fertiliser as growth begins, or use liquid feed monthly during the growing season. An annual mulch of well-rotted compost helps retain moisture and provides gentle nutrition whilst improving soil structure.
Formal Gardens
Perfect for formal garden settings where its naturally geometric form provides structure without the need for regular clipping. The symmetrical mounds create excellent punctuation points in formal borders and can be used to create low, informal hedging with remarkable uniformity.
Topiary Effects
Ideal for gardeners wanting topiary-like effects without the maintenance commitment. The naturally perfect dome shape eliminates the need for skilled pruning whilst providing the structural interest that clipped plants offer. Multiple plants can create stunning geometric displays.
Container Gardens
Excellent for containers where its compact size and evergreen nature provide year-round interest. The neat habit makes it perfect for formal container displays, and the summer flowering adds seasonal appeal. Choose containers with good drainage and be prepared to water regularly during dry periods.
Border Edging
Outstanding for border edges where its compact habit and evergreen foliage create reliable year-round structure. The neat growth won't overwhelm neighbouring plants whilst providing consistent form and seasonal white flowers that complement virtually any colour scheme.
Rock Gardens
Suitable for larger rock gardens where its dense habit and drought tolerance make it a valuable structural plant. The naturally rounded form contrasts well with the angular nature of rocks whilst the summer flowers provide seasonal colour.
Companion Planting
'Toparia' creates beautiful combinations with ornamental grasses, particularly those with fine textures that complement its small-leaved appearance. Pairs excellently with other evergreen shrubs for year-round interest, and the white flowers combine well with virtually any colour scheme. Particularly effective with purple-leaved plants like heucheras or silver-leaved artemisias.
Potential Issues
Generally trouble-free and remarkably resistant to pests and diseases when grown in appropriate conditions. The main concerns are poor drainage leading to root problems and occasional scale insect infestations. In very exposed positions, some winter protection may be beneficial in colder regions.

Buying Alpines from Jacksons Nurseries
At Jacksons Nurseries we lightly trim back our alpines after flowering 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 alpines, they may not look like images showing their ‘prime time’ in flower and looking at their best.
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
orders@jacksonsnurseries.co.uk.
From late autumn onwards and dependant 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.
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.

Alpines are a group of perennials that generally grow in rocky conditions at high altitudes.
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.
By using this simple guide and a little time, alpines can make an absolutely spectacular difference to your garden.
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.

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.
