[Until We Thrive Again]
When creating layouts in glass paludariums, I try to draw inspiration from the materials themselves — to sense the world they evoke and choose plants that harmonize with that atmosphere. For this piece, I used a piece of driftwood pierced with numerous honeycomb-like holes. Its rough texture and rigid, linear form offered little flexibility in placement and gave a strong impression of decay. What I felt from it wasn’t moisture, but dryness — and in response, I chose Hatiora as the central plant. This epiphytic cactus, known for its ability to grow even in rocky environments, has a kind of pioneering spirit. It takes root in withered places and slowly brings them back to life. The layout is an expression of that quiet resilience — the steady, determined effort of a plant restoring moisture to a dry landscape.

Hatiora salicornioides
Hatiora is a close relative of Rhipsalis, and part of the epiphytic cactus family. It’s well-suited for the drier areas of paludariums. It has fleshy leaves that branch out like coral.

Plectranthus ernstii
Plectranthus ernstii is a caudiciform plant belonging to the family Lamiaceae, native to South Africa. It grows slowly, but once the leaves have matured, it produces flower spikes with delicate pale purple blossoms.

Begonia dregei
This type of Begonia dregei is known for its maple-like leaves and relatively high drought tolerance. It forms a thickened, woody stem like a caudiciform and grows upright, tree-like. Its flowers are white and hang gracefully from the stems.
