Agapanthus Headbourne Hybrids

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?

Agave montana

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.

Giant Ornamental Onion Aprx 25 seeds җ җ җ
Allium giganteum a beautiful ornamental onion from Iran produces dense 9" heads of lilac-pink, star-shaped flowers in summer.

JS1486

Alyssum montanum Mountain Gold

Mountain madwort Aprx 100 seeds җ җ җ
I have never been without this useful and easy-to-grow spectacular spring flowering plant in our garden. Alyssum montanum  is low-growing 7 to 10cm and evergreen and produces masses of bright yellow flowers in clusters in late-spring. It's a perfect companion for spring bulbs or purple aubrietia  on a rock garden or bank, but also good in difficult, dry Mediterranean theme situations such as on a hollow topped wall or cracks in paving. It can also be used as a containerised specimen. It thrives in the poorest soil provided it's well-drained. Annual trimming after flowering prolongs the life of plants, improves later flowering and keeps plants compact.
JS2724

Amelanchier alnifolia

Saskatoon Service Berry 10 seeds җ җ җ
A fully hardy small to medium sized shrub from North America, Amelanchier alnifolia 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.

Double-Whip Cobra Lily 10 Seeds җ җ
This species grows native from Nepal & Northeast India to south central China. It has exotic looking dark purple to chocolate spathes striped or marked white. The mottled or purple-blotched leaf stem bears a huge tropical-looking shiny palmate leaf, divided to look a bit like three leaves with reddish brown margins. It is called a Double-Whip Cobra Lily because it has two tongues. The first is at the pointed tip of the hood or spathe, the "tongue" common to Arisaemas generally. But much stranger is an unexpected tongue that extends from the head of the spadix or jack. To 2ft.

Arisaema tortuosum

Whipcord Cobra Lily 10 Seeds җ җ
Described as tortuous because of the extremely long, curling green, sometimes purple, spadix which curves out of the mouth of the spathe tube and bends backwards tapering to a fine tip.

Arisaema triphyllum

Jack in the Pulpit 10 Seeds җ җ
Arisaema triphyllum or Jack-in-the-pulpit is a spring woodland wildflower usually growing 1ft to 2ft tall. Flower structure consists of the spadix (Jack) which is an erect spike containing numerous, tiny, green to purple flowers and the sheath-like spathe (pulpit) which encases the lower part of the spadix and then opens to form a hood extending over the top of the spadix. The outside of the spathe is usually green or purple and the inside is usually striped purple and greenish white, though considerable colour variations exist. Two large green, compound, long-petioled leaves (1ft to 1.5ft long), divided into three leaflets each, emanate upward from a single stalk and provide umbrella-like shade to the flower. The fleshy stalk and leaves lend an almost tropical aura to the plant.

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.

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

Cynara

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. 

JS1167

Cytisus scoparius Broom

Scotch Broom mixed colours 10 seeds җ җ
The ornamental broom plant, or Cytisus, is a lovely short lived shrub with evergreen, long whip-like branches covered in small leaves. The pea-like flowers bloom from late spring through mid-summer in shades of red, yellow, white pink and some bi-colours from our hybrid seed mix. Resistant to pests and tolerant of dry weather changes, the broom plant is ideal for a low-maintenance garden. I used to grow these all the time but it seems to have gone out of fashion for some reason which is a shame, perhaps because it is seen as a weed in some countries. However it never gave me any problems and it can be kept pruned to size for a few years before becoming leggy.

Fargesia yunnanensis

Clumping Bamboo 10 seeds җ җ

This beautiful and vigorous bamboo is native to the mountain forests of south-western Sichuan and Yunnan province of China. Its robust, clustering culms can reach a height of 7m to 10m and a diameter of up to 6 cm. The leaves are long, narrow and deep green. A fabulous and easy ornamental for cool and warm temperate regions. It is unharmed by moderate frost down to -8°C but not much lower so best in milder districts of the UK. The young shooths are edible and of excellent quality.
