Quick Verdict
Choose Mamei if you prefer the more elongated leaf form and redder new growth. Choose Silver Cloud if you want a rounder heart-shaped leaf with heavier silver coloration and more visibly wavy petioles. Both are crawlers, so they need horizontal room rather than a vertical climbing setup. For more close comparisons, collector varieties, and care guides, explore our Philodendron & Rare Aroids guide.

Mamei vs Silver Cloud at a glance
Mamei looks more elongated; Silver Cloud looks rounder
Mamei
The source describes Mamei as having the more elongated leaf shape. If you are also comparing Mamei with another crawler, see Philodendron Mamei vs Plowmanii.
Silver Cloud
Silver Cloud is described as rounder and more clearly heart-shaped.
The emerging leaf color can help
Mamei: new growth is described as red.
Silver Cloud: new growth is described as lighter or whitish.
Use this as a supporting clue rather than relying on a single emerging leaf.
Silver Cloud is described as more wavy
The source notes that Mamei tends to show more red in the petiole, while Silver Cloud has less red and a more strongly wavy or ruffled petiole.
Silver Cloud should look more obviously silver
The name is useful here: the source specifically describes Silver Cloud as having a more silvery appearance overall. For more unusual foliage forms beyond this pair, browse our rare Philodendron varieties.
Both plants are crawlers
Mamei and Silver Cloud move horizontally across the substrate. A longer planter is more useful than a standard moss-pole setup because it gives the stem or rhizome somewhere to advance. The Indoor Plants hub can help if you want to compare this growth habit with Monstera, Alocasia, easier houseplants, and other indoor plant groups.
Care is largely the same for both
If you are deciding whether a collector Philodendron is a good fit for your experience level, compare these requirements with our Philodendrons for beginners guide.
Light
Bright indirect light is the safest default.
Soil
Use a well-draining, airy aroid-style mix rather than dense soil.
Watering
Let the top portion of the substrate begin to dry, then water thoroughly.
Do not use a calendar
The original text included seasonal schedules, but drying speed changes with light, temperature, pot size, and substrate.
Buy for the problem your plant actually has
Mamei and Silver Cloud need the same basic environment, so the useful purchases are not variety-specific. Start with the bottleneck: insufficient light, uncertainty about room conditions, or a root zone that stays wet too long.

Room too dim?
Start with the grow light. Supplemental light is the most useful purchase when either plant is stretching, producing weak growth, or sitting too far from usable natural light.
Unsure about humidity?
Measure before adding equipment. A hygrometer tells you what the plant zone is actually experiencing instead of turning humidity into guesswork.
Mix stays wet?
Change substrate only when repotting is justified. A chunkier aroid mix can improve drainage and root-zone air space, but a healthy new arrival does not need an automatic repot.
SANSI Clip-On Grow Light
Buy this if: your Mamei or Silver Cloud does not receive enough usable natural light.
Why it earns its place: improving light addresses a fundamental growth limitation instead of adding unnecessary collector accessories.
Skip it if: the plant already receives strong bright indirect light for much of the day.
Check the SANSI Grow Light
Govee H5075 Hygrometer
Buy this if: heating, air conditioning, or seasonal changes make you unsure whether the plant zone is genuinely dry.
Why it earns its place: it gives you a real temperature and humidity baseline before you spend money on humidity equipment.
Skip it if: you already monitor the growing area reliably.

Molly's Aroid Potting Mix
Buy this if: you are already repotting and the existing substrate remains wet or compacted too long.
Why it earns its place: a chunkier mix can provide better drainage and air space around aroid roots.
Skip it if: the current root zone is healthy and draining properly. Amazon currently shows limited availability, so this is an optional repotting choice rather than an essential purchase.
Check Molly's Aroid MixWhat should you buy first?
Poor light → grow light. Unknown room conditions → hygrometer. Repotting because the substrate stays wet → aroid mix. If none of those problems exists, you probably do not need another accessory. Give the crawler horizontal growing room instead.
Choose the setup that matches your room
Mamei Setup
Use: long planter + chunky aroid mix + bright indirect light.
Why it works: matches the crawling growth habit.
Silver Cloud Setup
Use: long planter + stable light + room to display the silver foliage.
Why it works: lets the plant show its strongest visual difference.
Dry-Room Setup
Use: either plant + hygrometer, then add humidity support only if the room is genuinely dry.
Why it works: solves the real environment instead of guessing.
What makes identification harder
Looking at silver alone
Use leaf shape, new growth, and petiole structure together.
Identifying from one juvenile leaf
Mature foliage gives stronger clues.
Calling them climbers
Both are crawlers and need horizontal room.
Using fixed watering schedules
Water according to substrate dryness, not a specific number of days.
Which one are you looking at?
- More elongated leaf → Mamei.
- Rounder heart-shaped leaf → Silver Cloud.
- Redder new growth → Mamei.
- Lighter new growth → Silver Cloud.
- More reddish petiole → Mamei.
- More strongly wavy petiole + more silver foliage → Silver Cloud.
- Both are crawlers.
Frequently Asked Questions
What is the easiest way to tell Philodendron Mamei and Silver Cloud apart?
The supplied source points to leaf shape first: Mamei is described as more elongated, while Silver Cloud is rounder and more heart-shaped.
Is Silver Cloud more silver than Mamei?
Yes. The source specifically describes Silver Cloud as having a more obviously silvery leaf surface.
How does new growth differ?
The source describes Mamei new growth as more red, while Silver Cloud new growth appears lighter or whitish.
Do the petioles look different?
Yes. Mamei is described as having more reddish petioles, while Silver Cloud has less red and a more strongly wavy or ruffled petiole.
Are Mamei and Silver Cloud climbers?
No. Both are crawlers, so they need horizontal space for the stem or rhizome to advance across the substrate.
How should I water Mamei and Silver Cloud?
Let the upper layer of the substrate dry before watering again, then water thoroughly. Avoid fixed summer or winter schedules because drying speed changes with light, temperature, pot size, and substrate.
