Comparing Caudex and Leaf Forms: Five Collector Plants Coming to Yokohama

From adeniums to snake plants, what to notice before choosing a plant on 26 September

A swollen trunk, a caudex at the soil line, overlapping leaves that hold their shape and upright blades. On 26 September in Yokohama, different ways of growing will be visible in the outlines of five plant groups. The exhibitor guide for GreenSnap Marche YOKOHAMA 2026 AUTUMN names adeniums, Dorstenia, Stephania, tank bromeliads and snake plants.

Five names to compare in one place

The list comes from adeadenium, which is exhibiting on 26 September only. Rather than folding everything into the label “bizarre plants,” visitors can compare plants that draw the eye to the base, plants whose overlapping leaves form a vessel-like center and plants whose upright foliage shapes the space around them.

The adenium in the photograph is a representative plant, not one of the specimens promised for the event. Varieties, sizes, prices and stock can change on the day. The useful preparation is not a ranking of rarity, but a sense of which form holds your attention.

Use the label to begin a conversation

When a plant catches your eye, start with the botanical name and any cultivar name on its label. Recording the name attached to that particular plant, rather than stopping at a broad label such as adenium or snake plant, makes reliable information easier to find after you bring it home.

Then ask how it was propagated—by seed, cutting or division—and whether it is actively growing or closer to a resting phase. Questions about rooting, its most recent repotting and how it was managed before the event add a history that appearance alone cannot show.

Work backward from the place it will live

Before going, note the width of the available windowsill, the lowest winter temperature indoors and the hours of direct sun it receives. A photograph of the spot helps a seller picture the conditions. You can then compare the appeal of the plant with the conditions needed to keep growing it.

Look quietly beneath the leaves, around the base and across the potting surface. A mark or change in color is not automatically a problem, but it is worth asking about. Bizarre, exhibiting tank bromeliads and other plants on 26 September, says it will explain both their appeal and cultivation. Specific questions are part of the value of meeting specialist sellers in person.

The plants change between 26 and 27 September

adeadenium and Bizarre are listed for the 26th only. On the 27th, Jardín de Shonan plans to bring named agaves, caudex plants and cacti. SOUBU GARDEN appears on both days with moss terrariums, bonsai, caudex plants, carnivorous plants and other indoor specimens. Check the exhibitor day first if a particular group matters to you.

GreenSnap plant auctions are scheduled for 11:30 and 13:45 on the stone stage on the 26th. The organizer notes that the venue map may change and some booth positions may move in rain. Check the official update and the signs at the venue before setting out.

Two days in Yokohama

GreenSnap Marche YOKOHAMA 2026 AUTUMN runs from 10:00 to 17:00 on 26 September and from 10:00 to 16:00 on the 27th at Yamashita Park’s Festival Square. Instead of rushing to choose one plant, read its name, compare its form and ask about the time it has already spent in cultivation. That order can begin a longer relationship after the journey home.
