Acanthus mollis or Bear's Breeches has handsome large dark green shiny leaves deeply lobed, with impressive tall flower spikes in late summer.  Flowers are white with purple-shaded bracts. Outstanding for the back of the border, where this Acanthus will create a stunning effect. Tolerates some shade and dry conditions. Easy to grow.

Agapanthus Headbourne Hybrids

Hardy Nile Lily 10 seeds җ җ җ
Agapanthus Headbourne Hybrids are fully hardy, dying back to the fleshy root stock over winter. Available in most Garden Centres but expensive - why not try growing some from seed if you can wait a few years for the plants to mature?

Agapanthus umbellatus


Hardy Nile Lily 10 seeds җ җ 

Agapanthus Umbellatus has strong stems to 4 ft tall with large spherical heads crammed with rich cobalt-blue flowers. They are a beautiful sight to behold in full flower in Summer and have become particular favourites for larger pots.. They have handsome dark green, broad strap-like evergreen leaves but their evergreen nature makes them slightly less robust in cold Winters and in pots. Best brought under cover (no heat is required, just hard frost protection).in colder areas Flowers June-August.

Agave montana

JS 2409
Mountain Agave 15 seeds җ җ
One of the most exciting plants to recently come out of the Mexican mountains is this cool and wet hardy Agave montana. It forms a tight rosette of variably patterned and variably armed foliage of immense beauty, up to 1.5m across. Given a very well drained site in full sun this is by far and away the best Agave to try and grow outside in the UK

Allium aflatunense

Ornamental Onion Aprx 50 seeds җ җ җ
Allium aflatunense is a late spring perennial  flowering bulb with strap shaped pale green leaves appearing soon after the last frost. The globe shaped flowers are about 7 cm across, composed of dense tiny lilac florets on a strong single stem held well above the leaves. Height 90 cm. Spread 15 cm. Best in a well drained soil with full sun. Once established they will spread making quite a show in late spring to early summer.

Allium cernuum Hidcote Pink

Ornamental Onion Aprx 50 seeds җ җ җ
Allium cernuum Hidcote Pink is a very pretty ornamental onion to 50cm , this allium has pendulous loose flowerheads made up of clusters of bell-shaped, pink flowers. The fine leaved strappy foliage makes an attractive clump at the base of the plant.

Allium christophii

Persian Onion Aprx 50 seeds җ җ җ
Allium christophii is the largest of all the ornamental onions, with a huge 12" spherical head consisting of 80 individual star like purple flowers on strong stems up to 60cm high.  When they have finished flowering the seedheads can also be cut and dried for use in flower arrangements. Unlike many other varieties the strap like leaves remain in good condition while the plants flower and the flower heads last for weeks. Our favourite border ornamental onion.

Allium insubricum

Alpine Ornamental Onion 10 seeds  җ җ җ
From the Alps, this rare flowering onion is considered to be among the most desirable of Allium species. Allium insubricum is closely akin to the equally beautiful Allium narcissiflorum. It can be difficult to grow and flower well and best suited to alpine rockery conditions.

Alstroemeria ligtu hybrids

Peruvian Lily 20 seeds җ җ җ
Alstroemeria are exotic South American perennials from tuberous roots, producing abundant red, yellow, orange and pink flowers, often strikingly streaked and spotted. Excellent cut flowers. Easily grown in full sun or part shade, preferring rich deep soil. Best left undisturbed and mulched in hard frost areas. We have been growing these for many years with a fantastic colour display for most of the summer.


Service Berry 10 seeds җ җ җ
A fully hardy small to medium sized shrub from North America, Amelanchier has pretty snowy white flowers in spring and bears tasty edible blackcurrant sized fruits in mid summer. The plants tolerate a wide pH range and will also grow well in heavy clay soils. Water needs are minimal. Although fruit production is best when grown in full sun, partial shade is also tolerated. The berries are sweet and juicy, can be eaten fresh, canned, frozen, made into jams, pies or wines, and can be dried and eaten like raisins. Some say the taste is far superior to Blueberries without the problem of needing and acid soil to grow them.

Angelica gigas

Purple Angelica 10 seeds җ җ җ
From Korea, Angelica gigas is an architectural and quite dramatic recent introduction growing to 4’, with huge, bold leaves and striking flowers produced in mid to late summer in large clusters resembling a large Allium. Flowers and stem are a rich, purplish red and the plant won a gold medal in 1993 when it was introduced.

Anthriscus sylvestris Ravenswing

Purple Cow Parsley 10 seeds җ җ җ
Anthriscus sylvestris Ravenswing is a clump forming biennial or short-lived perennial with dark foliage providing a useful contrast in borders. The attractive dark purple-brown foliage and stems are followed in late spring to summer with lacy umbels of tiny white flowers, with small pink bracts. Pick out the best dark colours from the seeds discarding any green seedlings. Once established spreads easily from self sown seeds.

Aquilegia F1 Origami Mixed

Columbine 10 seeds җ җ җ
Aquilegia F1 Origami, a unique variety flowers the first year from seed because the cold stratification requirement is only 14-21 days with temperatures as high as 10C. An October/November sowing produces April/May flowering plants. Its hybrid vigour translates to a free flowering 12" to 18" habit with exceptional uniformity across all 6 colours that are clean and bright.

Arisaema consanguineum

Jack in the Pulpit 10 Seeds җ җ
One of the easiest to grow, but spectacular, is the giant Arisaema consanguineum. The flowers have a purple-green spathe with narrow, white, vertical stripes and a hood with a filamentous tail-like tip. The spathe encloses the club-like spadix (itself extended by a whiplash tail), which has all over its surface hundreds of tiny flowers. In late summer, the spathe withers and exposes a head of tightly packed red-orange berries. A slender tall plant (to 2 meters!) with mottled snake skin patterned stems.

Aruncus dioicus


Goats Beard Aprx 100 seeds

Goats Beard is a tall majestic plant with fine feathery plume shaped cream blooms similar to Astilbe. A giant back or border perennial reaching 120-150cm tall. Flowers June to August and perfectly hardy.

Astelia chatamica

Silver Spear 10 seeds җ җ
Astelia chatamica or Silver spear is a hardy, clump-forming perennial with elegant silvery spear-shaped leaves. In very cold winters in exposed areas plants may suffer frost damage and may benefit from protection. During mid- to late spring long stalks of yellowish-green flowers emerge from female plants that give rise to orange berries in summer. This plant can make a dramatic feature in the garden especially when planted close to purple-foliage plants such as Aeonium 'Schwarzkopf'. It makes an unusual alternative to phormium or New Zealand flax.

Baptisia australis Caspian Blue

False Indigo 10 Seeds җ җ җ
Baptisia australis forms a spectacular multi-stemmed plant specimen in the flower garden capped with lupine-like spires of this rich yet subtle shade of blue.  Each floret is centred white offering eye-catching contrast.  After flowering the uniform, vase shape of the plant bears rich green foliage all season offering a most pleasing architectural form.

Calla palustris


Bog Lily 25 seeds

This attractive marginal plant produces simple white arum-like flowers in May/June, followed by bright red berries in autumn. It has heart-shaped glossy mid-green leaves, and spreads on long creeping stems. It thrives in shallow water, making it one of the best plants for disguising the pond's edge with its lush greenery. Unlike many pond plants, it will grow and even flower in deep shade, although planting in sun or part shade will result in more blooms.

Calycanthus chinensis


Chinese Allspice 10 seeds

A deciduous shrub from Eastern China with glossy mid-green leaves, and camellia-like flowers up to 4" diameter. It will tolerate down to about -15C but prefers a sheltered site from cold winds and in partial shade rather than full all day sun. Large glossy green leaves and it should produce flowers after 3 or 4 years. Slow to germinate and some scarification necessary as encouragement.

Camassia quamash

Blue Camas 10 seeds җ җ җ
Camassia quamash are excellent plants and ideal for planting in a semi shaded garden position or in a wild meadow or orchard. Tall pale blue flower spikes in June. If they like their position they increase rapidly making them ideal for naturalisation. They become dormant in the winter producing underground bulbs.

Campanula carpatica Pearl Deep Blue

Carpathian harebell Aprx 50 seeds җ җ җ
Campanula carpatica are a robust, rock garden species, and will thrive on sunny walls or banks. They require moist, very well-drained soil and will grow in either sun or partial shade. Pearl Deep Blue blooms 2-3 weeks earlier than the species and is covered in cup-shaped 2 inch wide, vivid violet blue flowers with a lighter centre over dark green foliage from late spring to late summer. Regular dead heading increases the flowering period. Good choice for edging, containers, the front of borders, or growing among rocks.

Campanula pyramidalis Mixed

Chimney Bellflower Aprx 500 seeds җ җ
Campanula pyramidalis  is a superb and beautiful species forming a large basal cluster of leaves from which arise numerous pyramidal, leafy spikes of countless pale blue or white, saucer-shaped flowers, each 1 in. or more across, the whole making one enormous mass of bloom. Out of doors it will grow to a splendid 4 ft., but in your cool greenhouse, generously nurtured in a 10 in. pot, it will often reach a breathtaking 9 ft. or more! Often grown as a biennial but once established it tends to self seed. Certainly does in our garden!

Campanula takesimana Bell Ringers

Korean Bell Flower Aprx 50 seeds җ җ җ
An impressive discovery from Korea that is vigorous, easy and floriferous. Attractive glossy foliage supports nodding bells, faintly speckled or spotted maroon within. Excellent for quickly filling a border. Campanula takesimana Bell Ringers mixed has shades of pink, purple and white all with spotted centres.

Cardiocrinum giganteum

Giant Himalayan Lily 10 seeds җ җ җ
Although classed as a lily for many years, Cardiocrinum giganteum an aristocratic woodland plant from the Himalayas is unmistakably different. The bulbs eventually make 8" across, from which a rosette of leaves then appear for 2 to 4 years before an astonishing and stately flower spike erupts, with up to 50, 6" long glistening white very fragrant trumpets. After that the main bulb dies, leaving many smaller ones that take a few years to reach flowering size again. RHS AGM award. Slow from seed but very expensive to purchase bulbs.

Chiastophyllum Solar Yellow

Turtlehead aprox 25 seeds җ җ

Chiastophyllum Solar Yellow is a hardy, arching evergreen perennial with large fleshy ovate leaves often used in rockeries or containers. In spring an intense flush of yellow weeping flowers are produced creating a real splash of welcome colour. Best in well drained compost and partial sun.

Selected for its colourful foliage, 'Solar Yellow' is a cultivar of Chiastophyllum oppositifolium, a hardy succulent perennial from the Caucasus. It spreads slowly to form a mound of fleshy oval blue-green leaves 15cm to 20cm tall. Hardy to -20C

Chrysanthemum leucanthemum Crazy Daisy


Double Shasta Daisy aprox 100 seeds җ җ җ

The first medium tall Chrysanthemum with a high percentage of fully double flowers. The flowers are white with a yellow eye, many of the flowers have 'quill' type petals giving Crazy Daisy a fluffy look. 60-70cm. Flowers are ideal for cutting. Divide plants in the spring every 2 to 3 years to maintain vigour. Removing faded flowers regularly will greatly increase the blooming time. Attractive to butterflies.

Clerodendrum trichotomum


Glory Bower 10 seeds җ җ

Clerodendrum trichotomum or Glorybower, is a vigourous and fast-growing deciduous tree from China that produces masses of white starry flowers in summer that are followed in autumn by highly-ornamental metallic blue berries surrounded by maroon star-shaped caylces. A strong-growing plant, Clerodendrum trichotomum will quickly establish itself in a warm sheltered spot in the garden and will need a relatively generous space to accommodate its growth and may need active pruning every year to shape it and to cut back basal suckers. Hardy down to -10c this ornamental shrub is a must for any exotic garden.

Cordyline australis

Cabbage Tree 20 seeds җ җ
The Cordyline is a well known plant that needs little introduction, tolerating about minus 10°C without protection. If planted in more severe conditions it would require some protection, otherwise the growing point would be killed by the frost. However, even cut down to the ground you could expect new suckering growth the following year to compensate for any top growth loss. Many people leave the old leaves on the trunk to provide additional protection, or tie up the crown leaves during the worst weather conditions. This plant is readily available from most garden centres, but it is easy from seed, making it an excellent choice for any summer bedding scheme.

Cordyline australis purpurea

Cabbage Tree 20 seeds җ
This Cordyline produces an alternative, attractive purple/red foliage. Culture the same as above. Please bear in mind that the non green varieties are not quite so hardy if you are thinking of  a permanent position out of doors.

Cordyline indivisa

Large Cabbage Tree 20 seeds җ
A magnificent Cordyline species, growing to 8m, with a truly exotic bold look, this is slightly more tender than Cordyline australis and not so often seen in cultivation in the UK, frost tender to -5C. Cordyline indivisa differs from C. australis by having much broader leaves often with a red central midrib.


Cardoon 20 seeds җ җ җ
Cynara is an architectural clump forming plant which if given space really comes into its own. The plant shown in the picture is about 3 years old, already 10' across. Flowers are carried on strong stems up to 10' high and new foliage, beginning early autumn, is a very attractive soft blue grey. The flower form relates closely to the shape of a classic artichoke flower, slightly smaller and more delicate than the edible varieties, topped by a brush of bright blue flowers, quite stunning.  After the flowers fade I cut down the old stems and new growth soon forms from the base. These remain over winter growing slowly and looking very attractive, with only the occasional light frost damage before the spring heralds rapid new growth. Easy to raise from seed but you will need space to accommodate  it permanently. Young plants from off shoots or seedlings make excellent bedding before  becoming too large.

Cytisus battandieri

Pineapple Broom 10 seeds җ җ
A native shrub from the Atlas Mountains in Morocco. The dense clusters of pineapple scented yellow flowers appear in mid summer and together with the silvery grey green foliage present a wonderful sight. For well drained, even dry sandy soils in sun and tolerates frost to about -10°C. We have tried to acquire seeds of this wonderful Cytisus battandieri shrub for a few years and we are really pleased to be able to offer it again.
