01 — The Leaf Archive

Every surface
tells a story.

Macro documentation of rare cultivars — close enough to see the trichomes, the cell walls, the architecture of variegation.

Extreme macro of Monstera deliciosa leaf surface showing cell structure and trichomes under magnification

Monstera deliciosa

Swiss Cheese Plant

Fenestrations develop in response to wind patterns in the canopy — the holes let light through to lower leaves.

Close-up of Philodendron gloriosum velvety leaf surface with prominent white veining

Philodendron gloriosum

Velvet Philodendron

Velvety texture is caused by microscopic papillae on the leaf surface that scatter light.

Thai Constellation Monstera leaf with dramatic white variegation pattern on deep green background

Monstera 'Thai Constellation'

Thai Constellation

Stable chimeral variegation — white cells lack chloroplasts, creating the constellation pattern.

Calathea ornata pinstripe leaf showing intricate pink stripe pattern on dark green surface

Calathea ornata

Pinstripe Calathea

Nyctinasty — leaves fold upward at night, a circadian rhythm older than most animals.

Alocasia zebrina leaf underside showing dramatic patterned petiole and pale green reverse

Alocasia zebrina

Zebra Elephant Ear

Zebraprint petioles are a form of aposematism — the patterns may deter herbivores.

Hoya kerrii heart-shaped leaf with waxy surface texture in raking light

Hoya kerrii

Sweetheart Hoya

Succulent-like leaves store water — a single leaf can survive months without roots.

Weeks of watching.

Real propagation journals — humidity readings, substrate experiments, and the small victories that don't photograph well.

Monstera deliciosa var. borsigiana

Thai Constellation — Cutting #3

14 Feb 2026

Propagation — Day 23

"Root nubs visible at node junction. Water temp holding at 22°C. Slight yellowing at cut end — trimmed 2mm and refreshed sphagnum. Humidity tent maintaining 87%. First aerial root emerging from the internode."

Velvet Phil — Soil Transition

08 Feb 2026

Soil Transition — Week 2

"Moved from LECA to chunky aroid mix (30% perlite, 30% orchid bark, 20% coco coir, 20% worm castings). New leaf emerging — petiole showing the characteristic white stripe. No transplant stress observed. Watered to runoff with pH 6.2 solution."

Dragon Scale — First Unfurl

19 Feb 2026

New Growth — Day 7

"Third leaf of the season unfurling. The scale texture only fully develops after the leaf hardens — currently still soft and almost translucent at the edges. Kept away from direct airflow. Calcium deficiency suspected in previous leaf — added CalMag to last two waterings."

Named and placed.
Carefully.

Botanical illustrations peeled apart into labeled diagrams. Distribution, habitat, authority — the full scientific record.

Liebm., 1849

Monstera deliciosa

Swiss Cheese Plant

Order

Arales

Family

Araceae

Distribution

Southern Mexico to Panama

Habitat

Tropical rainforest understory

Growth Form

Hemi-epiphytic climber

Described

Liebm. (1849)

Field Notes

Juvenile leaves entire; adult leaves develop fenestrations and perforations. Produces edible fruit — the only edible Monstera.

André, 1876

Philodendron gloriosum

Velvet Philodendron

Order

Alismatales

Family

Araceae

Distribution

Colombia, Venezuela, Ecuador

Habitat

Cloud forest floor, 500–1800m

Growth Form

Terrestrial creeping rhizome

Described

André (1876)

Field Notes

Velutinous leaf surface with contrasting white venation. Terrestrial — unlike most Philodendrons, it grows horizontally along the forest floor.
