An August border can be full and still feel unfinished. The leaves occupy every patch of soil, yet the flowers that carried June have gone, leaving a blank area in the view. Before buying another plant, identify that area precisely. Is colour missing near the path, through the middle, or above the planting? The answer makes a late-season daylily search much more useful.
This selection follows ten suppliers available to British gardeners, each with a named daylily whose own product description includes August. Some offers are described specifically as late flowering. Others have a July-August or July-September window. Those are different routes to the same practical aim: finding plants worth considering for colour during August, without promising that every clump will flower continuously throughout the month.
Keep the distinction between a flower and a clump in view. Each individual daylily bloom is short-lived, while the succession of buds gives the plant its flowering period. Weather, establishment and local conditions influence when that succession happens. A catalogue calendar is a useful planning guide, not an appointment that the plant is obliged to keep.
The calendar behind this selection
The first filter was an explicit August reference attached to the supplier’s named offer. The second was its contribution to an actual gap: colour, flower shape and height where published. Material and access then identify a workable purchase. This keeps the selection tied to the month and to a particular product, including collection offers and stock enquiries where those are the available routes.
Johnny Come Lately leads because Swallowtail Daylilies identifies August directly in the cultivar’s description. The remaining suppliers explore overlapping summer windows, several flower shapes and different routes to buying the plants. Their positions do not claim measured flowering durations or predict which will last longest in your garden. The purpose is to build a realistic shortlist from published calendars and specific offers.
1. Swallowtail Daylilies
August is stated plainly for Johnny Come Lately at SwallowtailDaylilies, making this a particularly direct starting point for a British daylily planting aimed at late-summer colour. The cultivar’s name is memorable, but its written flowering description is what earns its place here.
The nursery describes warm ginger, cinnamon, gold and copper tones, with a four-and-a-half-inch bloom on a thirty-inch stem. Those details suggest a useful transition into the warmer colours often chosen for the later border. At roughly seventy-six centimetres tall in flower, it can contribute above lower planting without depending on a towering stem.
On the plan, put Johnny Come Lately against a middle-height gap that would benefit from warm colour. Its ginger-to-copper description could continue warmth already present elsewhere instead of making the late addition look unrelated. The nursery’s August designation gives the plant a clear seasonal task. Ordering and establishment have their own timing, so choose it for a future late-summer contribution rather than expecting an August purchase automatically to arrive in flower.
2. Macplants
Marion Vaughn gives Macplants an offer with a July-September window. August sits within that span rather than at its beginning or end. The flowers are pale yellow, fragrant and star-like, and the supplier lists a height of eighty-five centimetres.
For a planting plan, this is a gentler colour bridge than Johnny Come Lately. Pale yellow can connect the later border to earlier lemon or cream tones without requiring a sudden shift into copper and orange. The stated season also makes the offer worth considering where the aim is a transition through August towards September.
Macplants lists a 2-litre product for Marion Vaughn. A gap that needs pale yellow through a relatively high part of the view is the one to test against its 85cm guide. Great Dixter later provides another source of the cultivar with a different height account. Keeping those offers separate makes the shopping comparison clear once the plant’s pale, star-like flower is the wanted effect.
3. Farmyard Nurseries
Double River Wye has a July-September description at Farmyard, with lemon-yellow double flowers and a listed height of sixty-five centimetres. The nursery offers a two-litre pot. It brings a fuller flower shape into the same broad calendar space as Marion Vaughn.
That change of form can matter as much as a change of colour. A double flower provides a more layered centre, so it may become a stronger close-up feature among simple, open blooms. If the August bed already feels busy, Marion Vaughn’s simpler outline could be the more suitable yellow; if it needs a more decorative focal detail, Double River Wye offers a reason to choose differently.
A close-view gap near a seat might make the layered lemon flower especially welcome. Farmyard’s July-to-September window gives it a plausible place there in August, subject to the plant and season. The 2-litre offer makes that specific choice available to investigate, with more decorative fullness than Marion Vaughn in the same broad colour family.
4. Claire Austin
Little Grapette is listed for July and August, carrying small, soft-purple flowers with crinkled edges. Claire Austin gives it a height of forty centimetres and spread of thirty, with a nine-centimetre pot as the supplied format.
It fills a different part of the seasonal picture from the taller yellows. A border can have August flowers at the back and still look thin near its front. Little Grapette is relevant where that lower layer needs purple detail, particularly when a large, dominant flower would overwhelm nearby planting.
Mark the low gap on the drawing and give Little Grapette its 30cm spread allowance. The small purple flower then has a defined purpose, rather than merely qualifying for a list of plants that might bloom in August. Higher yellow flowers can remain visible behind it. The border’s seasonal repair becomes more coherent when each added plant occupies a different part of the missing display.
5. Cotswold Garden Flowers
Royal Celebration introduces red-purple flowers with twisted, spreading petals. Cotswold Garden Flowers lists July-August flowering and a seventy-centimetre height, supplying the plant as a bare-rooted division.
This is an option for a later summer border that needs a more open flower outline. Its red influence also gives it a warmer character than Little Grapette. The two can both be relevant to August while answering different colour and scale problems.
The bare-root division is a plant to establish for that future display. Royal Celebration’s warm purple could connect redder colours elsewhere in the August bed, while its twisted petals introduce movement into a dense patch. Those two features distinguish it from Little Grapette’s softer, smaller flower even before the difference in their stated heights is considered.
6. Great Dixter
Great Dixter also lists Marion Vaughn, here with a July-August season and a height of one metre. Its pale yellow flowers therefore provide another documented route to the August brief, with a different supplier description and purchasing option.
Once Marion Vaughn’s pale colour appeals, Macplants and Great Dixter offer a direct purchasing comparison. Their flowering windows overlap in August; their height guides differ. Keep each seller’s figures with the corresponding order details and allow the established plant some latitude in the garden.
The one-litre option was available when reviewed; the smaller nine-centimetre variant was not. Choose the listed size deliberately. This entry is most useful once the pale yellow, taller-flowering role appeals and the remaining question is which actual product to order.
7. Ballyrobert Gardens
Ballyrobert includes June, July and August in its description of Happy Returns and also identifies its repeat-flowering habit. Both pieces of information matter here. Repeating bloom is an interesting characteristic, while the stated months supply the direct evidence for the August theme.
The lemon-yellow, ruffled flowers could continue a yellow theme already present in the August bed. Ballyrobert lists a half-litre pot as available, giving a small potted start to that choice. Its repeat-blooming description adds context to the calendar, but the explicit August entry is the reason it belongs in this seasonal search.
For an order from Ballyrobert’s Northern Ireland nursery, check the delivery arrangements for the intended address. The half-litre Happy Returns is the product to compare, with its summer months and lemon flowers kept together. That provides a definite option for continuing yellow into the later plan without switching the whole planting towards a new colour.
8. Swines Meadow Farm Nursery
The nursery’s Hemerocallis fulva Europa offer lists July-August flowers in orange-red, with ruffled petals, and a three-litre pot. It gives the August shortlist a warm-coloured alternative to the yellow and purple choices.
That combination is useful where the planting already contains orange accents and needs the colour to continue into later summer. The larger stated container is also a concrete product difference, although it does not guarantee a particular first-season display or a fixed number of flowering stems.
Ask Swines Meadow about the 3-litre Europa before paying; the nursery requires stock confirmation. Its orange-red ruffled flowers could continue a warm planting into the July-to-August window described. Once availability is established, that named offer can become part of a firm order for the later display.
9. Hoo House Nursery
Hemerocallis citrina offers a species choice with a clear July-August calendar. Hoo House describes lemon-yellow flowers and a height of one hundred centimetres, giving the selection another taller, lighter-coloured component.
Hoo House sells for collection. A nearby gardener can enquire about citrina as the tall lemon component in an August plan, especially where lower flowers are already plentiful. Establish availability before organising the visit. The reason for the enquiry is the species’ listed 100cm height and July-to-August display.
10. Harley Nursery
Flore Pleno closes the list with double orange-brown flowers and a dark red eye. Harley gives it a July-August flowering period and an eighty-centimetre height, with a spread of seventy-five centimetres in the catalogue description.
This is a more densely layered warm-coloured option than the simple pale-yellow flowers elsewhere in the selection. The dark eye adds another point of interest, which may be welcome in a planting that needs a stronger late-summer focal detail. Its documented August window is the foundation of that recommendation.
Harley’s collection and local purchasing arrangements make this an option to assess around your own access to the nursery. The offer is particularly relevant if the desired combination is double form, warm colouring and an August-inclusive season. A need for nationwide postal delivery should be resolved before making it part of a firm order.
Build an overlap rather than a deadline
A useful August plan might begin with one specifically late cultivar, then add a contrasting offer whose published window crosses the month. Johnny Come Lately and Little Grapette, for example, answer different colour and height needs while both having an explicit August connection in their supplier descriptions.
Return to the marked gap before finalising the order. Would the chosen flower occupy the missing level, and would its colour belong with what remains in August? If so, allow the plant time to establish and keep a short note of its local season. Next year’s decision can then answer a more precise need. The aim is a late-summer border that looks complete, with each addition doing a recognisable job.
Source note: Flowering windows, plant descriptions and purchasing formats come from the ten suppliers’ product pages and catalogues; collection and stock-confirmation limits are included where they affect the route to obtaining the plant.
