Great Dixter in East Sussex maintains one of the most influential perennial borders in the world, yet its plant palette owes a quiet debt to a network of small, family-run alpine nurseries in the Czech Republic. Many of the most coveted garden plants begin not in tissue culture labs or breeding programmes, but as seed collected responsibly from wild populations under national permit systems. Sourcing that seed legally and ethically demands patience, paperwork, and an understanding of the international frameworks that govern plant movement — but for gardeners seeking authentic species material, the rewards are considerable.
The international seed trade inhabits a regulatory space that is far simpler than the live-plant equivalent. Most seed shipments under 5 kg and intended for personal propagation require only a phytosanitary certificate from the country of origin, rather than the full import permit and post-entry quarantine demanded by live nursery stock. Countries operating under the International Plant Protection Convention (IPPC) issue these certificates after inspection confirms freedom from listed pests and diseases. For the home gardener, this means seed can arrive through standard postal channels without the expensive freight-forwarding and inspection fees that make importing live plants prohibitive.
Understanding CITES and the Nagoya Protocol
The Convention on International Trade in Endangered Species (CITES) lists species whose trade is controlled or prohibited. Most familiar garden plants fall well outside its remit, but alpine enthusiasts seeking specialist saxifrages, terrestrial orchids, or certain bulbs must check the CITES appendices before ordering. Cypripedium species, for example, appear on Appendix II, meaning international seed shipments require both export and import permits. The cost and administrative burden often render such transactions impractical for small quantities, and many specialist nurseries now refuse CITES-listed material altogether.
Equally significant is the Nagoya Protocol on access and benefit-sharing, which came into force in 2014. This supplementary agreement to the Convention on Biological Diversity requires users of genetic resources to obtain prior informed consent and establish mutually agreed terms with the provider country. In practice, this means that seed collected from wild populations in ratifying nations — including India, South Africa, and most of the European Union — must be accompanied by documentation demonstrating compliance. Reputable seed merchants are increasingly transparent about their collection permits, and some now include Nagoya compliance statements in their catalogues. The gardener sourcing Dierama seed from a South African collector, for instance, should expect to see reference to a permit issued by the relevant provincial conservation authority.
The Alpine Nursery Network of Central Europe
The most rewarding source of unusual perennials for the British gardener is the constellation of small alpine nurseries stretching from the Czech Republic through Slovakia, Austria, and Slovenia. Many of these businesses operate on a scale that would be commercially unviable in Western Europe, cultivating plants from wild-collected seed obtained under their own national permit systems. The Czech firm Euroseeds, based near Brno, publishes an extraordinary list of over 2,000 taxa, many collected by the owner on expedition to Central Asian mountain ranges. Their annual catalogue includes collection data — altitude, location, and date — a practice that reassures buyers of both legality and provenance.
Slovakian nursery Pavelka’s Plants specialises in high-altitude alpines, offering seed of species rarely seen in British catalogues: Androsace villosa from the Tatra Mountains, Gentiana frigida from the Carpathians, and an extraordinary range of Daphne. Orders from these nurseries arrive with phytosanitary certificates as standard, and the seed quantities are generous enough to allow for the inevitable losses of alpine propagation. Gardeners should expect to pay between £2 and £8 per packet, plus shipping, and to order in autumn when fresh seed becomes available.
“The Czech and Slovak alpine growers are the unsung heroes of perennial diversity. What they offer is genuine wild-origin material backed by proper permits — exactly what a responsible plantsman should be seeking.” — Dr Kit Strange, former curator of the Alpine House, Royal Botanic Gardens, Kew
North American Seed Banks and the Wildflower Trade
Across the Atlantic, a parallel tradition of small-scale seed collection has produced some of the most interesting perennial introductions of the past three decades. American seed banks such as Alplains in Colorado and Western Native Seed in Colorado and surrounding states operate under permits from the US Forest Service and Bureau of Land Management, collecting seed from discrete wild populations and selling it in quantities suitable for the home propagator. Their catalogues read like a flora of the Rocky Mountains: Penstemon species in bewildering variety, Aquilegia forms unknown to European gardens, and an extraordinary range of Eriogonum.
Orders from North America require a USDA phytosanitary certificate, which reputable suppliers arrange as a matter of course. The cost of this certificate — often around $25–$50 — is added to the invoice. Delivery to the UK typically takes between two and four weeks, and gardeners should time orders to avoid the summer heat, which can damage seed viability in transit. Autumn ordering aligns well with the natural dormancy cycles of many temperate perennials, and seed can be sown immediately upon arrival or stored cool and dry for spring sowing.
Japanese and East Asian Perennials: A Special Case
Japan presents a more complex proposition for the home gardener, largely because its domestic horticultural industry has not developed the small-scale seed catalogue culture found in Europe and North America. Most Japanese perennial seed moves internationally through botanical garden exchange programmes, which are governed by institutional agreements and are not available to private individuals. However, a handful of specialist Japanese nurseries are now offering seed to overseas customers, often through English-language sections of their websites.
The Hokkaido-based nursery Miyama Shokubutsuen offers seed of Japanese alpine plants including Primula sieboldii in colour forms rarely seen in the West, and the Tokyo firm Kōbe Alpine Nursery has begun listing seed of Japanese woodlanders such as Anemonopsis macrophylla and various Epimedium species. Phytosanitary certificates are available on request, and the Japanese Ministry of Agriculture, Forestry and Fisheries maintains a relatively efficient inspection system. Gardeners should be aware that some Japanese species are subject to domestic collection restrictions, and reputable nurseries will state clearly when material is nursery-propagated rather than wild-collected.
“The Japanese seed trade is opening up slowly, but the gardener must be vigilant. Look for explicit statements about propagation origin. If a Japanese species is offered without any collection data or propagation note, assume nothing.” — Rosy Hardy, Hardy’s Cottage Garden Plants, Hampshire
The Self-Collecting Option: What the Law Allows
Gardeners travelling abroad often return with envelopes of seed collected from roadsides or wild habitats, unaware of the legal risks. In most countries, collecting seed from protected areas without a permit is illegal, and in some — Australia and New Zealand are notably strict — even dead plant material requires a collection permit and a phytosanitary certificate for export. Within the European Union, plant health regulations are harmonised, and small quantities of seed for personal use can move freely between member states. However, the moment seed is posted across an external EU border, phytosanitary requirements apply, even for the smallest private transaction.
The responsible approach is to apply for collection permits in advance when possible, and to limit wild collection to species that are abundant locally. National park authorities in countries such as Georgia and Turkey have been known to issue seed-collecting permits to amateur botanists for a modest fee, and several British tour operators now offer guided trips that include legal seed-collecting opportunities. The Alpine Garden Society runs occasional expeditions with collecting permits pre-arranged, and participants can bring home seed of species including Campanula choruhensis and Verbascum wiedemannianum entirely within the law.
The Garden Destination: Building a Perennial Collection from International Seed
The practical endpoint of all this international sourcing is the propagation bench. Seed arriving from high-altitude and continental climates often requires specific germination triggers: cold stratification, scarification, or exposure to fluctuating temperatures. Gardeners ordering seed from the Czech alpine nurseries should invest in a copy of the Nordic Journal of Botany germination database or the Royal Horticultural Society’s propagation literature, which detail the requirements of many unusual species. The work is considerable, but the genetic diversity captured in wild-collected seed often produces plants that are demonstrably tougher, more floriferous, and longer-lived than their vegetatively propagated commercial counterparts.
A single successful order from Euroseeds or Alplains can populate a border with perennials that are genuinely rare in cultivation. The plants that result are not merely acquisitions but propagules of wild genetic resources, conserved ex situ in British gardens. When the gardener shares seed with the Hardy Plant Society or the Cottage Garden Society exchange schemes, that material enters a distributed conservation network that has quietly preserved countless garden-worthy species for decades — a process that begins with a carefully placed international order, a bundle of paperwork, and a packet of seed arriving in the post.
A single order from Pavelka’s Plants in the Tatra foothills reveals a deeper truth about the alpine nursery network: its survival depends on a generation of growers now approaching retirement, and the regulatory burden described in the draft is accelerating a quiet crisis. The Czech and Slovak nurseries that supply British gardeners with wild-origin seed are typically one-person operations, often run by botanists in their sixties or seventies who learned their craft under the state-run botanical institutes of the Communist era. When those institutes were disbanded or privatised in the 1990s, many former researchers established private nurseries using their existing permits and collecting routes. Three decades later, their catalogues are unmatched in Europe, but succession plans are rare.
The Nagoya Protocol, introduced in 2014, has added administrative layers that these small businesses struggle to absorb. A Slovakian nursery such as Ladislav Hrib’s Alpines, which offers over 1,500 taxa from Carpathian collections, must now document prior informed consent for every species collected in a Nagoya-ratifying country. The paperwork for a single expedition to the High Tatras can require weeks of correspondence with national park authorities, university ethics committees, and the Ministry of Environment. Many of these growers are unwell or fatigued; Dr Kit Strange notes that three of the ten most important alpine nurseries in Central Europe have closed in the past five years, their proprietors citing regulatory exhaustion as a primary cause. The loss is tangible: the closed nurseries hold propagation know-how that cannot be recovered from seed banks or published literature.
British gardeners face a narrowing window of opportunity. The Alpine Garden Society has begun a programme to archive seed from retiring Czech and Slovak growers, but the scale of the challenge is vast. A single order from Euroseeds or Pavelka’s Plants is not merely a shopping transaction — it is an intervention in the preservation of a living botanical tradition. Gardeners who delay sourcing Gentiana frigida or Androsace villosa from these sources may find that within a decade, the seed no longer exists in the commercial trade. The responsible course is to order now, propagate generously, and share the resulting progeny through the Hardy Plant Society exchange schemes, ensuring that these genetic lineages persist beyond the working lives of the men and women who collected them.
