On 10 August 2026, PostNL released Beleef de natuur – flora Saba, the fourth and final stamp sheet of the 2026 Experience Nature series. The sheet contains 10 postage stamps in 10 different designs. The stamps bear the denomination 1 for mail up to 20 grams within the Netherlands, and a sheet of 10 stamps costs €14.00.
The stamp sheet is part of the multi-year Beleef de natuur (Experience Nature) series, dedicated in 2024–2026 to the biodiversity of the Caribbean Netherlands. Each year, four stamp sheets are released, each with 10 different stamps depicting plants and animals native to this part of the Kingdom of the Netherlands. The islands boast an extraordinary biodiversity, with thousands of species of flora and fauna — a richness unparalleled in the European Netherlands.
The 2026 Saba Series
In 2026, PostNL is devoting four consecutive stamp sheets to the biodiversity of the windward island of Saba: birds (released 5 January), butterflies (30 March), underwater life (8 June), and flora (10 August). The fourth and final sheet, Beleef de natuur – flora Saba, shines a spotlight on the island's remarkable plant life.
The 10 plant and tree species featured on the stamps are:
About Saba
Saba — together with Bonaire and Sint Eustatius — is a special municipality of the Netherlands, collectively referred to as the Caribbean Netherlands. Alongside the autonomous countries of Aruba, Curaçao, and Sint Maarten, these islands form the Caribbean part of the Kingdom of the Netherlands. Saba belongs to the windward islands, a name derived from their position relative to the prevailing northeast trade winds.
Located 30 kilometres northwest of Sint Eustatius and 45 kilometres southwest of Sint Maarten, Saba is a roughly circular island about 4.5 kilometres in diameter, with an area of just 13 square kilometres. Geologically, Saba is a dormant volcano with four lava domes. At 870 metres, Mount Scenery — the highest point in the entire Kingdom of the Netherlands — is covered in tropical rainforest and cloud forest, a special type of rainforest found only on mountain slopes. The humid, misty air condenses on the mountain's slopes, giving the island's lush flora a hazy, atmospheric character rarely seen on Dutch stamps.
Design and Designers
The stamp sheet Beleef de natuur – flora Saba was designed by graphic designer Frank Janse from Gouda. Each of the 10 plants and trees is portrayed in its natural habitat on its own stamp. All photographs are embedded in a graphic layer of circular motifs that extends onto the sheet margin. In some places, the imagery continues across adjacent stamps and onto the selvage.
Janse enriched the sheet with graphic elements derived from symbols found on old topographical maps — representing landforms, contour lines, vegetation, soil structures, and waterways. A distinctive feature of the design is an additional transparent layer with monochrome images (both white and in colour) of characteristic fauna. These translucent depictions run across the perforations, visually connecting the stamps with one another and with the sheet margin. The following plants are rendered in this way: elephant ear (top left), yellow blossom (top right), Caribbean bladderwort (centre), leaves of the West Indian treefern (bottom left), and leaves of the West Indian mahogany (bottom right).
For the typography, the designer used DIN 2014, a typeface designed by Vasily Biryukov from Bulgaria and released by Paratype in 2015.

Why This Issue Matters
The Beleef de natuur – flora Saba stamp sheet rounds off PostNL's 2026 tribute to the remarkable natural heritage of the Caribbean Netherlands. From the majestic West Indian mahogany and the ancient West Indian treefern to the carnivorous Caribbean bladderwort, the sheet showcases the extraordinary botanical diversity of Saba's cloud forests — one of the most biodiverse yet lesser-known corners of the Kingdom of the Netherlands.
For collectors of nature-themed stamps, Caribbean philately, or the Beleef de natuur series, this sheet is an essential addition. The sophisticated design by Frank Janse — with its interplay of photography, topography-inspired graphics, and translucent overlays — makes it a particularly appealing piece for those who appreciate thoughtful stamp design. With a circulation of 275,000 sheets, it is widely available but remains a significant record of the Netherlands' Caribbean natural heritage.
