  2. PROTEA OBTUSIFOLIA

    An absolutely glorious variety, having sizeable, shiny, richly coloured flower heads during winter. One of the very few proteas that can thrive in both alkaline or acidic soils, making it one of the most adaptable proteas for many gardens. With a robust-growing habit, it makes a large upright rounded shrub, 2–4 m tall with a spread of up to 5 m, and an incredibly stout main trunk up to 600 mm/2feet in diameter. The inner involucral bracts are hairless and shiny with a fringe of silver white hairs along the margin, the colour varying from deep carmine to creamy white, with many shades of pink in between. Flowering occurs from autumn until spring, peaking during midwinter dependent on location. Proteas require extremely well drained soil which is both acidic and very low in nutrients, fertiliser containing excess phosphates or nitrates may kill them (this variety being the exception) Proteas should not be fed with standard liquid feeds. Protea feed is available from specialist stockists. Proteas prefer full sun on a south facing slope in an open unshaded position. ... Learn More

  3. PROTEA REPENS

    The large deep red flowers of this sturdy, densely shrubby Protea are an excellent addition to any "wild-life" garden, as the large amount of nectar produced attracts birds, bees and other insects. The latin name "repens" is wrong and was caused by a mix-up in ancient times. The botanist Thunberg later named the same plant Protea mellifera, referring to the sweet nectar produced by the flowers. However, this later correct name was not valid so so this upright shrub is now called Protea repens! Proteas require extremely well drained soil which is both acidic and very low in nutrients, fertiliser containing excess phosphates or nitrates may kill them! Proteas should not be fed with standard liquid feeds. Protea feed is available from specialist stockists. As a rule proteas prefer full sun on a south facing slope in an open unshaded position. ...

    This rarely-offered plant has striking, linear, purple-brown and white foliage. This slow-to-grow endemic shrub from South Island, Fiordland, the Southern Alps and northwest Nelson in New Zealand is more of less hardy, preferring montane to low alpine forest in damper regions mainly west of the Main Divide. ...

  6. PTEROSPERMUM ACERIFOLIUM

    Large fragrant nocturnal white flowers open on stems bearing enormous mature leaves which can reach a length and width of up to thirty five centimetres. Indeed, they can be used as actual dinner plates or as packaging and storage for wrapping materials inside. The leaves are also used as a primitive method of re-enforcing roofs and preventing leaks. The wood is flexible and durable and is often used for box making. Mostly planted as an ornamental or shade tree, the leaves, flowers, and wood thus all serve a large variety of functions. It is home to Southeast Asia, from India to Burma. ... Learn More

  7. PUTRANJIVA ROXBURGHII

    This attractive, moderate-sized, evergreen tree flowers from March to May when its yellowish male flowers crowd into rounded axillary clusters, the female flowers being solitary and greenish yellow. It has pendent branches and dark grey bark, with both bark and leaves being used as medicine, the leaves and fruits traditionally used as medicine for rheumatism. The fleshy fruit has a hard seed-containing stone within, which is strung into necklaces for putting on children, the belief being they ward off evil. The plant contains mustard oils as a chemical defence against herbivores and is widespread across SE Asia. ... Learn More

  8. QUERCUS ILEX (ACORN)

    This large spreading evergreen tree bears dark green leaves which are tough and leathery, with pale undersides. Finally becoming a large and impressive specimen, it is native to the Mediterranean region, although it grows well in almost all parts of the UK once established. The male flowers are catkins and the female flowers give rise to large seeds or "acorns", in a very similar way to the English Oak, Quercus robur. Seeds are rarely produced, and only in "Mast" years which occur with oaks only every five to ten years, hence their scarcity. It takes one of its common names from 'holm', an ancient name for holly (whose botanical name is Ilex). ... Learn More

  9. QUERCUS ROBUR (OAK TREE) ACORN

    It can take a full 50 years before this tree has its first crop of very large seeds, called acorns, which are produced on attractive "pixie pipes". Sadly, these seeds are not produced every year, but only in occasional "Acorn or "Mast" years when the tree has built up strength and feels like it! These special years occur with oaks only every five to ten years, hence their scarcity. We have numerous old oaks growing here, so we are always able to sell fresh, top grade, carefully cold-stored seeds, grown and collected from our own ancient 200 to 300 year old oak trees at Plant World. This most well-known and best-loved king of the forest can live for more than a millennium and can take as long as 150 years before producing the strongest and most durable timber. Until the middle of the 19th century, when iron took over for building ships, thousands of oaks were felled every year, it was estimated that it took 2,000 trees to make a single large ship. Plant one for your grandchildren! ... Learn More

  12. RHODODENDRON MACABEANUM

    This is not just a superlative rhododendron, it is in fact one of the most magnificent plants one can grow. Maturing as a large evergreen shrub, it can, in many years, become a tree, with enormous, magnificent, glossy dark green leaves up to 30cm in length, with whitish down beneath. The large flowers, in dense rounded trusses, are bell-shaped, cream to pale yellow with a purple blotch in the throat. Both the BBC and Independent TV companies filmed this in full flower during the spring here in Plant World Gardens, whilst visitors come to our gardens especially to see these plants in full bloom! ...
