Thalictrum - Zantedeschia
Plant names highlighted in green have images attached, click to view.

Thalictrum actaeifolium var. brevistylum BSWJ8819 £4.50
A pink flowered job which is said to reach 1.5m (not for us). It’s the shape of the leaflets which give a distinct and very attractive look.
Thalictrum aquilegifolium ‘Thundercloud’ AGM £5
Quite tall, early to mid-summer flowering, with flowers of a nice dusky purple.
Thalictrum cultratum £4.50
One of those minus types which you grow for the lovely, stiff, very finely divided foliage which is held with great poise. The flowers are dominated by the rich brown anthers, well into the growing season. 50cm.
Thalictrum delavayi ‘Album’ £5
Pure white flowered form of the classic large flowered, fine leaved border variety. It’s anthocyanin-free, so the leaves are a pure light green. Lovely.
Thalictrum ‘Elin’ £5
A spectacularly tall, and self-supporting Swedish hybrid which gets its purple tinted stems and violet flowers from rochebrunianum, and its glaucous leaves and height (3m+) from flavum var. glaucum. By division, from stock we’ve had for many years, from before it was tissue cultured, if such things matter to you.
Thalictrum omeiense ex DJHC 762 £4.50
Clouds of little white flowers in spring over unusually brown-tinted (Sarah says chocolate) foliage. 30cm. From wet limestone cliffs, but suits woodsy conditions. I do not understand why this is so rarely grown.
Thalictrum squarrosum £4
Another shorter species, with pretty clusters of yellow-green flowers very early in the growing season. Widespread in NE Asia.
Thalictrum uchiyamae £4.50
For us, a splendid tall (1.8m) upright thing with good sized lilac flowers and pretty green leaves with rounded leaflets. Tigridia orthantha is on a break, but it will return with some exotic colleagues.
Tricyrtis formosana ‘Dark Beauty’ £4.50
The Toad Lilies are autumn flowering plants for moist soil in some shade. This about as dark and as blue as they get.

Tritonia
Relatives of Crocosmia from South Africa, well proven as garden plants. A burgeoning collection here.
Tritonia crocata group varieties £4
Lots of tubby flowers crowded on 30cm stems in late spring. Winter green. For a sunny, well drained spot. Bulks up quickly to make a striking clump. Good in a pot, potted on or split annually at the end of summer, and put in the greenhouse during cold snaps. T. deusta and T. squalida may be involved here too. I’d like to call this group by its South African name, the Mossel Bay kalkoentjies, but I can’t pronounce it.
‘Pink Sensation’- clear pink, probably a form of squalida; ‘Princess Beatrix’ - intense orange with dark basal blotches; ‘Prince of Orange’ - vivid orange; ‘Serendipity’ - a delicate light orange, ‘Tangerine’, ditto, but the first to flower, and ‘Plymouth Pastel’ - very delicately blended pastel shades of orangey yellowy pink .
Tritonia deusta £4
Vivid orange. Somebody pointed out to me that the dark blotches are little browny purple hearts. Ahhh.
Tritonia disticha ssp. rubrolucens tall pink form £5
Classic tall species, 1m high in flower. Like a delicate Crocosmia, carrying lovely clear pink flowers on wiry, branched stems in late summer. Easy in good soil in sun. Winter dormant. The form we’ve offered for years, originally from South African seed.
Tritonia disticha ssp. rubrolucens shorter redder form £4
More like 60cm tall at the end of flowering, a little earlier, and a redder pink - perhaps carmine describes it best. The Cornish consider this the usual form.
Tritonia lineata winter growing form £4
This species is variable, and while it mainly lives in the Eastern Cape, does extend into the winter rainfall area. Rather a tall plant - up to 40cm - with cream flowers, veined brown outside. May flowering, before dying down.
Tritonia laxifolia£3.75
Orange, outfacing flowers on a 25cm plant in May. A winter grower for us.

Trollius x cultorum ‘Pritchard’s Giant’ £5
A tall variety reaching 1m on fertile moist soils, with large upfacing rich yellow flowers with a hint of orange.
Trollius stenopetalus £5
Big, bold, upward facing abut fully open buttercup yellow flowers. 60cm.

Tulbaghia - Society Garlic

Tulbaghia ‘Bob Brown’ £4
A putative violacea / cernua hybrid which usefully combines the vigorous evergreen (usually) clumps and tall flower stems of violacea, with the subtle merging green/purple/yellow colours in the flowers normally found only in winter dormant species. Pretty hardy and easy, flowering in early summer.
Tulbaghia cernua CDR 199 £4.50
Broad leaved, winter dormant plant with stout crowns. Small green flowers with yellow coronas in summer. 50cm. Sun, ideal for a pot.
Tulbaghia ‘Cosmic’ £4
An evergreen violacea hybrid, with a decent head of pink-purple, not uniformly coloured flowers, with a chunky yellow corona. It’s quite tall, in the way of violacea. Thanks to Liz Powney, a lady who takes her National Collection seriously. All power to her and her informative website tulbaghia.com.
Tulbaghia ‘Fairy Star’ £4
Short (25cm) with fine leaves and starry lilac-pink flowers. Very floriferous and distinctive. Evergreen too.
Tulbaghia ‘Fairy Snow’ £4
A white flowered counterpart to ‘Fairy Star’, with just a hint of lilac in the tube. Our own seedling, and one of those names just waiting to happen.
Tulbaghia ‘Hazel’ £4
Yet another taller evergreen hybrid, this time with flowers of a strange but attractive brownish pink. The corona is yellow, tipped with brown. Night scented – cool! I really rate this plant – thanks again, Liz.
Tulbaghia ‘John May’s Special’ £4
A splendid large selection, up to 80cm in height with 2cm diameter mauve flowers in summer and autumn. As hardy as tulbaghias get, in well-drained soil in sun. Evergreen, a violacea or close hybrid – the best of those types.
Tulbaghia leucantha H&B 11996 £3.75
Little orange and brown flowers on thin 20cm stems. Fast bulking and free flowering. The form once known as dieterlinii.
Tulbaghia leucantha larger form £4
Creamy-green with orange corona - height 25cm.
Tulbaghia ‘Moya’ £4
An evergreen hybrid with rather small but remarkably rich purple flowers with an orangey brown corona. 30-40cm tall in flower. Raised by Jaap Duis and distributed under the number Otterlo 927 before it was named.
Tulbaghia natalensis B&V 421 clone 1 £4
Clusters of white flowers on 15-20cm stems, in late spring. Winter dormant. Floriferous and beautifully scented. The V of B&V is Canio Vosa, chromosome man and Tulbaghia expert, who I remember from my time at Oxford. The academic world divides remarkably sharply into those who treat students as if they were fellow human beings, and those who, well, don’t. Dr Vosa was one of the good ‘uns. We dealt with the B back in the Ks – were you paying attention?
Tulbaghia ‘Peppermint Garlic’ £4
An American selection, almost as tall as John May’s, but with larger, paler flowers. Very nice.
Tulbaghia ‘Purple Eye’ £4.50
A widely admired fine-leaved evergreen hybrid, selected by Dick ‘Agapanthus’ Fulcher. It does the ‘Fairy Star’ thing, flowering on and on, but is about half as big again, in height and flower size. The lilac-pink flowers are set off by a purple corona in the middle. A very good plant.
Tulbaghia violacea pallida £4
Pretty white flowers from pale pink buds; 50cm. Tough.
Tulbaghia violacea ‘Silver Lace’ £4
Beautiful silver variegation contrasts well with pink-purple flowers on 30cm stems. Bulks up to form an attractive clump, but best given some protection in colder parts of the UK. Often flowers more freely in pots.

Tulipa sprengeri AGM £3.75
The classic easy, lovely, slender, red, late flowering tulip species which naturalises so well in grass, even in quite a bit of shade as at Kingston Bagpuize House. Always in short supply.
Uvularia grandiflora 'Lynda Windsor' £5
Butter-yellow leaved version of the classic woodsy species. The yellow cast isn’t transient, but lasts right into the summer. I know you may not like yellow leaved things. If you do, I reckon this is a good ‘un.
Uvularia grandiflora 'Pallida’ £4.50
More normal glaucous green leaves, but very pale creamy yellow flowers in this form.
Veratrum formosanum £5
Quite unlike the familiar stout, large leaved, slow-bulking curse-of-the-cows species, this narrow leaved Taiwanese plant has spikes of really dark blackish red flowers in late summer. Slugs love it as much as nigrum, I’m afraid. Always in great demand.
Veratrum nigrum AGM £4.50
And here’s the classic dark flowered monolith, with splendid pleated foliage. A year or two off flowering size, these. I’ll say it again, beware slugs!
Vernonia arkansana ‘Mammuth’ £5
The effect is somewhere between Aster and Eupatorium - rich violet-purple composite flowers on tall stems, 2m+ under the right conditions. An excellent plant for the border in autumn.
Veronicastrum latifolium £4
This is a traily / climby species, which can root to form fair sized clumps or ramble through shrubs. Small blue flowers in axilliary clusters. Interesting and pleasant, but not for tidier parts of the garden.
Veronicastrum virginicum ‘Lavendelturm’ £5
The usual 2m stems with whorled leaves, with branched spikes of lavender flowers in this case. Self supporting. I picked it out in the garden at Beth Chatto’s as being somehow more graceful in habit than other varieties, but I still can’t put a finger on why.
Wachendorfia thyrsiflora £5
What an interesting plant! From dense clumps of dark green, corrugated leaves in fans, emerge furry 1.5m stems bearing yellow flowers in summer. South African, and hardiest on well drained soils in mild gardens, but still only borderline. Easy and drought tolerant in a large pot: this also allows you to break the ice at parties by showing your friends its vivid orange roots. Or maybe not...

Watsonia
One of the great genera of the Iridaceae from southern Africa, with Gladiolus-like corms and leaves, and spikes of showy flowers in spring or summer. Hardiness varies: all these should be hardy in mild coastal gardens experiencing just a few degrees of frost at night. Most can take much more and are good doers across the south and west of Britain. Grow them in full sun, avoiding poor, dry soils. All make good pot subjects, and can be overwintered under glass in cold districts. Well grown clumps become congested after 3-5 years, and flower better if lifted and split up. Always handle them in late summer, after flowering and before root growth has got under way.
All these priced £5 for largest sizes, but of course smaller ones will be cheaper.

Watsonia ‘Dart Sea Trout’
Our own seedling from the splendid ‘Tresco Dwarf Pink’ is one of the pretty, floriferous, long tubed types in a soft salmony pink, unlike anything else here. Height 1m.
W. aletroides has unique tubular flowers in a 2-sided spike, a delicate soft red in colour. Ours reaches around 40cm, though it can be taller.
W. angusta is an evergreen from wetter habitats with light orange flowers, reaching about 1m. Tough.
W. brick red hybrid is a long tubed type, 1.5m, a deeper, softer colour than ‘Stanford Scarlet’.
W. borbonica pink formis a lovely clear pink, and seems quite tolerant of heavy, wet ground. Early season. It’s great favourite of ours.
W. borbonica ‘Arderne’s White’is the classic white watsonia, large flowered, and a pure opaque white.
W. knysnana (silent k, y as in ‘eye’ - named for the town) is a large flowered mid-season pink in our form.
W. laccata Pink Form: related to aletroides. Pink open faced flowers from smart ‘varnished nails’ bracts on slender 60cm stems: really lovely.
W. laccata Orange Form is just the same but a soft peachy orange . Thanks to Dick ‘Agapanthus’ Fulcher.
W. marlothii
A tall species endemic to the Swartberg and rarely offered for sale. The flowers are medium sixed, short tubed in a many flowered spike. Most commonly scarlet flowered, this seed collection is turning out to be pink, in varying shades.
W. ‘Peachy Pink Orphan’ Tall, semievergreen and hardy, with short, curved light peachy pink flowers. pillansii influence.
W. pink hybrid is a fantastic colour, despite the prosaic name. Very long, branched inflorescences of big, screeching pink flowers make it a real traffic stopper. Cold, wet winters may be fatal, so look after it! Later season.
W. ‘Stanford Scarlet’(another tough pillansii hybrid) reaches 1.5m high in our heavy soil, with loud orange-scarlet flowers. Close inspection is rewarded by the beautifully contrasting indigo anthers.
W.’Tresco Dwarf Pink’ is a charming, very floriferous and hardy shell pink variety, more compact at around 60cm.

Wulfenia x schwarzii £4
Related to Veronica, with 30cm spikes of deep blue flowers in spring, over clumps of rounded glossy green leaves. Sun, ordinary soil. I’ve no idea why this fine, easy plant is so rarely seen.
Ypsilandra thibetica £4.50
Belonging to the Melanthiaceae, and close to Heloniopsis, this is a distinctive woodland perennial forming clumps of leafy rosettes. The flowers, in spring, are in tight bunches, white in bud and when first open, ageing pink in fruit. Eminently growable, it will probably become more widely planted than any Heloniopsis in time.
Zantedeschia odorata £7
Imagine a low-growing, fragrant, winter growing version of the classic big white Z. aethiopica, and you pretty much have it. It’s endemic to the Bokkeveld Plateau, and unlike Z. aethiopica (which is native to both summer and winter rainfall areas of South Africa, and absolutely not Ethiopia) doesn’t become a summer grower in Britain. Keep it in a pot in the cool greenhouse and dry it out in summer, at least for a little while. If leaf tips start to show, water it up again. The scent is of a delicate floral soap. We were given material of two stocks, each grown in Gloucestershire and kept frost-free over winter, by Robin Sibson and John Grimshaw. Prof. Sibson flowers it every year; John had to wait a long time (see the informative piece on his blog). We immediately dispensed with all heat, as usual, gave them very well drained compost, and set them off. Some flowered. Some didn’t. None seemed badly bashed up by frost when on the dry side. As with other aroids, we think size of crown is key to flowering, but what
conditions help you achieve that? Try it. You won’t often get the opportunity.
