Haworthia
Small South African rosette succulents, split in recent taxonomy into Haworthia, Haworthiopsis, and Tulista — nurseries still mostly sell them under the old combined name, and care is identical across the group.
Haworthia / Haworthiopsis
Haworthia spp. / Haworthiopsis spp.
Botanical notes
Compact rosettes of thick, fleshy leaves. Haworthia proper often has translucent "windows" at the leaf tips that let light reach internal tissue; Haworthiopsis species tend toward firmer, more ridged or textured leaves without windows.
Soil & moisture
Gritty cactus/succulent mix with sharp drainage. Water thoroughly, then let the pot go fully dry — soggy soil is the fastest way to lose this plant.
Fertilizing
Diluted cactus fertilizer twice during the growing season is plenty.
Common mistakes
- Overwatering — the dominant cause of loss by far
- Regular potting soil instead of a gritty succulent mix
- Intense afternoon direct sun scorching window-leaved species (morning sun is safer than afternoon)
✓ Pet safety
Generally considered non-toxic to cats and dogs — one of the safer choices on this list if it ends up somewhere reachable.
Propagation
Divide offsets/pups that form around the base of the parent rosette — the fastest and most reliable method. Individual leaf propagation is possible but slow and not always successful.
CR note
A great choice for a bright windowsill that gets some direct morning sun; keep it away from intense unfiltered afternoon sun through glass, which can still scorch it.
Hedera
A classic trailing/climbing vine — easy indoors in a pot, but worth keeping contained rather than let loose outdoors.
Variegated English Ivy
Hedera helix 'Variegata'
Botanical notes
A woody climbing/trailing vine with lobed, cream-edged juvenile leaves. Given a support to climb, mature growth can eventually shift to a different, non-lobed leaf form and even flower — rare in a home setting.
Soil & moisture
Standard well-draining potting mix. Consistent light moisture suits it better than a dramatic dry-out cycle.
Fertilizing
Light balanced feeding monthly during growing season.
Common mistakes
- Dry indoor air inviting spider mites — mist or increase humidity if you spot fine webbing
- Overwatering causing root rot
- Letting it root into garden soil outdoors, where it can spread aggressively
⚠ Pet safety
Toxic to cats and dogs (saponins), causing drooling, vomiting, or GI upset if chewed — worth keeping trailing stems out of easy reach.
Propagation
Extremely easy — stem cuttings root readily in water or moist soil within a couple of weeks.
CR note
English Ivy is considered invasive in a number of warm, humid regions once it escapes into the ground. Best kept strictly as a contained pot or hanging basket plant in Costa Rica rather than allowed to root into garden beds.
Hemigraphis
A low, creeping groundcover named for its puckered, "waffled" leaf texture — easy, fast, and a great filler for humid shaded containers.
Variegated Waffle Plant
Hemigraphis alternata 'Exotica Variegata'
Botanical notes
Low, creeping habit with textured, puckered leaves — the solid-color species is typically metallic purple-silver, while this variegated cultivar adds streaks of cream and pink.
Soil & moisture
Moisture-retentive but still well-draining mix; consistent dampness suits it far better than a dry-down cycle.
Fertilizing
Light balanced feeding monthly in growing season.
Common mistakes
- Too little light fading the variegation toward plain green
- Letting it dry out fully, causing crisping
- Leggy, sparse growth from not pinching regularly
Propagation
Very easy — stem cuttings root quickly in water, and trailing stems will root on their own wherever a node touches moist soil.
CR note
A strong choice for a shaded, humid patio container where it can spread and trail — CR's ambient humidity does most of the work.
Hypoestes
A cheerful, short-lived shrubby plant grown for spotted foliage — best treated as a plant to refresh from cuttings every year or two rather than one to keep indefinitely.
Polka Dot Plant
Hypoestes phyllostachya
Botanical notes
Small, shrubby plant with leaves speckled pink, white, or red. Naturally short-lived and prone to getting leggy and sparse with age — regular pinching and periodic replacement from cuttings keeps it looking its best.
Soil & moisture
Well-draining, moisture-retentive mix; consistent moisture suits it better than letting it dry between waterings.
Fertilizing
Light balanced feeding monthly during growing season supports its fast growth.
Common mistakes
- Letting it flower and set seed, which noticeably shortens the plant's vigor — pinch off flower spikes as they appear
- Too little light fading the spotted coloring
- Keeping an old, leggy plant indefinitely instead of refreshing it from cuttings
Propagation
Very easy from stem cuttings rooted in water or moist soil — the best way to keep a fresh, full-looking plant long-term.
CR note
Grows quickly in Costa Rica's warmth, which also means it ages through its natural cycle faster — take cuttings proactively every several months to always have a fresh plant on hand.
Ledebouria
A small bulbous succulent from South Africa, low-maintenance and quietly self-multiplying at the soil surface over time.
Silver Squill
Ledebouria socialis (syn. Scilla violacea)
Botanical notes
Small bulbs sit partly above the soil surface, sending up silver-green, purple-spotted leaves with deep purple undersides. Naturally clump-forming, producing new bulblets around the base of established ones over time.
Soil & moisture
Well-draining, slightly gritty mix. Plant bulbs shallow, with the top visibly exposed — burying them too deep encourages rot.
Fertilizing
Light feeding during active growth is enough; this genus needs very little.
Common mistakes
- Overwatering, which rots the bulbs
- Planting bulbs too deep instead of leaving the tops exposed
- Letting the clump get overcrowded for years without dividing
Propagation
Separate the small offset bulbs that form around the parent bulb and pot them individually — the easiest and most reliable method.
CR note
A low-fuss choice for a bright windowsill or covered patio shelf; it multiplies happily on its own with minimal attention.
Monstera
Climbing aroids native to Central American rainforests — genuinely at home in Costa Rica's climate. All three below want something to climb: fenestration and leaf size both improve dramatically once the plant is allowed to grow vertically against a moss pole or similar support, mimicking how it climbs tree trunks in the wild.
Monstera deliciosa
Monstera deliciosa
Botanical notes
Large, iconic split and perforated ("fenestrated") leaves on a climbing vine that produces aerial roots to anchor itself to trees. Mature, well-lit, well-supported plants can eventually produce an edible fruit — hence "deliciosa" — though this rarely happens in typical indoor conditions.
Soil & moisture
Chunky, well-draining aroid mix (bark, perlite, peat/coco coir). Provide a moss pole or similar support — climbing plants develop larger, more fenestrated leaves than ones left to sprawl.
Fertilizing
Balanced fertilizer at half strength every 4 weeks during growing season.
Common mistakes
- Too little light producing small, unfenestrated leaves
- No climbing support, limiting eventual leaf size
- Overwatering, particularly in a mix that isn't chunky enough
⚠ Pet safety
Toxic to cats and dogs (calcium oxalate crystals) if chewed, causing oral irritation and drooling; unripe fruit is also unsafe. Worth training climbing stems away from spots pets frequent.
Propagation
Stem cuttings with at least one node and, ideally, an aerial root establish reliably in water or moist sphagnum moss before potting up.
CR note
Genuinely native to the region and one of the easiest, most rewarding growers on this whole list here — a bright, covered patio spot with a support to climb suits it beautifully.
Monstera adansonii
Monstera adansonii
Botanical notes
Smaller, thinner, more heavily perforated "Swiss cheese" leaves than M. deliciosa, on a faster-growing, more compact vine — equally happy climbing or trailing from a hanging basket.
Soil & moisture
Chunky, well-draining aroid mix. A support to climb produces larger, more fenestrated leaves; left to trail, leaves stay smaller.
Fertilizing
Balanced fertilizer at quarter to half strength every 4 weeks in growing season, given its fast growth.
Common mistakes
- Overwatering in a mix that isn't well-draining enough
- Very low light producing sparse, small leaves
- Letting vines get long and bare without pinching to encourage fullness
⚠ Pet safety
Same oxalate-crystal toxicity as other Monstera if chewed.
Propagation
Stem cuttings with a node root readily in water within a few weeks — one of the easier Monstera species to propagate.
CR note
Does well both trailing from a hanging basket on a covered patio and climbing indoors — a versatile, fast-growing choice for the collection.
Thai Constellation Monstera
Monstera deliciosa 'Thai Constellation'
Botanical notes
A tissue-culture-propagated cultivar with stable cream-and-green speckled variegation — unlike some variegated plants, it won't revert to solid green, but the reduced chlorophyll does make it a meaningfully slower, more deliberate grower than standard M. deliciosa.
Soil & moisture
Chunky, very well-draining aroid mix. Because growth is slower, it's easy to accidentally overwater relative to actual use — let it dry a bit more between waterings than a green Monstera.
Fertilizing
Quarter strength balanced fertilizer every 5–6 weeks in growing season — light feeding to match its slower metabolism.
Common mistakes
- Watering on the same schedule as a faster green Monstera, causing rot
- Too little light, which this cultivar tolerates worse than green deliciosa
- Pale/white leaf sections being more prone to bacterial or fungal spotting — avoid getting water on the leaves and ensure good airflow
⚠ Pet safety
Same oxalate-crystal toxicity as other Monstera.
Propagation
Stem cuttings with a node root in water, though more slowly than green Monstera — patience and stable warmth help.
CR note
Reserve your brightest indoor spot for this one, with good airflow around the leaves to reduce the fungal-spotting risk that comes with humid conditions and pale leaf tissue.
Peperomia
A large, varied genus of compact, semi-succulent plants — thick, water-storing leaves mean the single most common mistake across the genus is overwatering. Also a genuinely reassuring one: most Peperomia are non-toxic to pets.
Watermelon Peperomia
Peperomia argyreia
Botanical notes
Rounded, silver-and-green striped leaves on red petioles, resembling watermelon rind — a compact rosette-forming species.
Soil & moisture
Light, well-draining mix. This is a genus where the soil should dry out meaningfully between waterings — soggy soil is by far the most common cause of stem rot at the base.
Fertilizing
Light balanced feeding every 6 weeks in growing season; it needs relatively little.
Common mistakes
- Overwatering, causing rot right at the soil line
- Too little light producing leggy, sparse growth
- Watering on a fixed schedule instead of checking soil dryness first
✓ Pet safety
Considered non-toxic to cats and dogs — a safe choice for lower shelves or more accessible spots.
Propagation
The classic method: a leaf with a short piece of petiole attached roots readily in soil or water, eventually producing a new plantlet at the base.
CR note
A forgiving, compact choice for shelving or a desk spot with bright but indirect light.
Peperomia caperata 'Schumi Red'
Peperomia caperata 'Schumi Red'
Botanical notes
Deeply corrugated, rippled leaves in a rich burgundy-red, forming a dense, compact rosette — one of the more dramatic-textured Peperomia cultivars.
Soil & moisture
Light, well-draining mix; water at the soil line rather than overhead, since the tightly packed crown can trap moisture and encourage rot or mold if watered from above.
Fertilizing
Light balanced feeding every 6 weeks in growing season.
Common mistakes
- Watering into the crown and trapping moisture, inviting rot
- Overwatering generally, given its succulent-like water storage
- Low light causing the rosette to stretch and lose its compact form
✓ Pet safety
Non-toxic to cats and dogs.
Propagation
Leaf cuttings (leaf plus a short petiole) root easily in soil or water, same method as Watermelon Peperomia.
CR note
Water carefully at the base rather than misting overhead, given how humid CR air already is — extra surface moisture on this compact rosette isn't needed and can invite fungal issues.
Variegated Baby Rubber Plant
Peperomia obtusifolia 'Variegata'
Botanical notes
Thick, glossy, rounded succulent-like leaves marbled cream and green on a compact, bushy plant — no relation to true rubber plants (Ficus) beyond the resemblance of its thick leaves.
Soil & moisture
Light, well-draining mix. One of the easier-going Peperomia — quite tolerant of missed waterings, much less tolerant of consistently wet soil.
Fertilizing
Light balanced feeding every 6 weeks during growing season.
Common mistakes
- Overwatering, the main risk given its thick, water-storing leaves
- Too little light fading the cream variegation toward solid green
- Assuming it needs frequent watering because the leaves look lush — they don't
✓ Pet safety
Non-toxic to cats and dogs — a genuinely safe option for a spot within reach.
Propagation
Stem or leaf cuttings root easily in soil or water within a few weeks.
CR note
An easy, low-maintenance choice for a bright shelf or side table — genuinely one of the most forgiving plants in the whole collection.
