Gladiolus

This is our inactive listing for this genus.

The category is for plants which we normally offer but which are not currently available for ordering.

They are showing 'out of stock' either because they are sold out at the moment or because they are seasonal and currently unsafe to send.

These species are however a normal part of our range and we would hope to have them available, and included in the active list again, in the next correct season.

Please check on the left hand side of the screen, we may also have an active list (of other, different species) for this genus.



Ordering of different species from Autumn and Spring lists.

Gladiolus atroviolaceus

This has distinctly violet flowers and not the usual pink-purple of the genus. These are marked with deep violet stripes on the lip around a paler throat. There are several flowers, laxly held on an upright stem that can be from as little as 20cm up to 50cm tall.

Spread from Greece to Iran. Remarkably hardy and readily grown in well-drained, loam soil in sun, or a pot.

Gladiolus carmineus

This species is unique in its autumnal blooming, it flowers in September in the UK, before the leaves come into growth. It normally has grey-green foliage and flower stems, the latter carrying 4-5 large flowers of rich deep pink to near-carmine, marked on the lower petals with white.

Hardy in the UK with good drainage and sun being its ideal combination, it does not need lifting for winter. It is native to South Africa growing there on sandstone cliffs.

Gladiolus communis byzantinus

Gladiolus communis byzantinus

A readily grown species from the Mediterranean region with slender spikes of pink, bright carmine or magenta flowers. These can be marked with paler and darker lines in some plants.

A deep fertile soil is best with the plants left undisturbed, to encourage flowering rather than increase.

Horticultural stock originally from plants raised in a wet area of Scotland rather than the more widely grown Dutch horticultural forms. We hope that in some way this may make them more amenable to the British climate.

Gladiolus cunonius

A very bright red, spring flowering species with long tubular flowers each of which has an elongated upper petal.

A native of sandy soils in the Cape province of South Africa.

Readily grown and very attractive for the intensity of the colouring in its flowers and its tidy, narrow foliage.

Gladiolus flanagannii

Gladiolus flanagannii

A rare and highly protected species in the wild, this has, fortunately, taken well to cultivation. In South Africa it goes by the name of ‘Suicide Gladiolus’ in allusion to its natural habitat in inaccessible crevices in vertical cliffs, trying to get to them is tantamount to killing yourself! It hangs from basalt cliffs which run with water at some times of the year.

This species has stunning, vivid red flowers with long tubes and has adapted itself for pollination by the Malachite Sunbird which migrates to higher areas, when the plant is in flower, to probe for its nectar. In cultivation it needs only a well drained, humus rich soil to perform well. Increase is by seed and offsets, and of course there are those fabulous flowers, arguably the best in the genus. Certainly if you only grow one hardy Gladiolus this has to be the one.

Gladiolus illyricus

A hardy species native to southern and western Europe and the Mediterranean basin. It flowers from about April onwards in a variety of habitats which are mostly well drained and sunny. Stems with up to 10 flowers (facing in two different directions) bear quite large, showy, flowers of carmine, magenta or bright pink, each bloom with three pale pink, or white, streaks on the three lower petals.

Easily grown in any rich, fertile, well drained soil in full sun. Best planted deep and better not potted, lest the bulbs split up too much - which does not happen planted deeply, in the garden, and left alone.

Gladiolus kotschyanus

An unusual Asian Gladiolus found from Anatolia to Iran and Iraq, where it grows in habitats ranging from boggy meadows to sub-alpine levels.

It make just two or three, 1cm wide, ribbed leaves and a 40-60cm stem with a superb spike of individually large flowers of a crimson-violet shade, rare in the genus and hard to describe. Individuals with a far paler ground colour are also known, often with darker markings and frequently bicoloured. Our stock contains these lovely forms also.

Very hardy and an excellent garden plant rarely seen in cultivation however it is not difficult in a well drained, humus-rich soil in sun, a damp spring may benefit it, but is not essential.

Gladiolus robertsoniae

Gladiolus robertsoniae

Slender growths and spikes of beautiful, virtually white flowers with tiny red pencillings inside the flower, contrasted with yellow pollen. It is deliciously and powerfully spice-scented in the evening, an indication usually of Moth pollination.

This is restricted by lack of a suitable conditions in the wild as it is eminently growable and sets good seed in cultivation. Despite its wild habitats, it is best in a fertile, well-drained, very sandy but humus-enriched soil with good drainage but ample water when growing. This is not a garden species. It dislikes cold wet winter conditions though it is adapted to cold, due to its high altitude habitat. Frost-free cultivation is best, but with the minimum of heat needed to prevent freezing through, but not enough to encourage too much winter-growth. Good air circulation is also helpful with almost all of the winter-growing S. African Gladiolus.

A rare species from high altitude grassland in Mpumalanga. One of the rarest of Gladiolus in S. Africa, with a restricted and decreasing habitat, due to the advance of agriculture.

Gladiolus saundersii

The "Lesotho Lily" has 50-90cm tall stems bearing large flowers of salmon to scarlet with an infusion of orange. In contrast, the lower petals are white in the centre with the white speckled with the same scarlet-orange shades. The region around can sometimes, rarely, be a darker shade, as in our plants.

Reliably cold hardy, this can overwinter in the ground as long as it does not sit in stagnant wet conditions. In the wild it is a native of the highest regions of the Drakensberg Mountains of South Africa where it occurs at over 2700m near the ski resort of Tiffindell.

Hardy in the UK it likes deep planting in a fertile, well-drained soil in full sun and lack of disturbance. Very little known but extremely deserving of cultivation.

Gladiolus sericeovillosus

This is a summer-growing, winter-dormant species from South Africa.

It has large, robust stems, reaching 80-100cm, or even 120cm tall in vigorous specimens, with broad, ornamental leaves below a two-sided spike of cream to softest caramel flowers often with a pink-infused hood, giving a bicoloured effect. Rarely, green marked or wine red flowers are known. Flowers start to appear in July. The whole plant is densely covered in small hairs.

Grown from seeds from South African seed though a different subspecies is known from Zimbabwe at considerable altitude (2,000m +). Supposedly hardy to -15°C and readily grown in the garden, outside, in a fertile, sunny spot in a decent soil with good drainage. Lifted and dried for the winter if you are not convinced that it is hardy.

Gladiolus symonsii

Many, more experienced, growers will have heard of the winter-green species of South African Gladiolus. These grow on a Mediterranean type cycle of winter wetness and summer dryness. I would bet that few gardeners are familiar however, with a far smaller group of species, from higher altitudes, which are summer growing and possibly hardy in the UK.

G. symonsii is one of the latter group. It starts leaf growth in spring and flowers in mid- to late-summer, with slender spikes of beautiful pure sherbet-lemon-yellow flowers (in this unoublished colour form). These are attractive and graceful, smaller than the monstrous creations of the hybridist but far, far more attractive.

These have been raised from seed in the UK and overwintered outside, in frames but unprotected. The species may be hardy - but please note the italics.

Gritty, well drained yet peaty soil in full sun and perhaps amenable to pot cultivation inside.

Drakensberg Mountains of South Africa, at altitude.
