Black Rose Aeonium
Aeonium arboreum 'Zwartkop'

Ravenea rivularis
Also known as: Ravenea Palm
A large, statuesque palm with a full crown of arching, feathery fronds. Naturally grows along riverbanks, so it prefers consistently moist soil compared to many other indoor palms.
Watering amount
Estimated guideline, not a precise measurement — scale up for larger pots, brighter light, or active growth; scale down for smaller pots, lower light, or winter dormancy. Always water until it drains from the pot's base rather than measuring exactly.
Season note
Keep soil evenly moist (not waterlogged); check the top inch of soil before watering, and avoid letting it dry out completely.
Overwatering signs
Yellowing leaves in consistently wet soil
Underwatering signs
Crispy, browning leaf edges, dry potting mix
Light level
bright indirect
Best rooms
Soil
Well-draining, loamy potting mix
Humidity
Prefers high humidity; benefits from misting or a humidifier
Fertilizer
Palm-specific fertilizer monthly during spring and summer
Temperature range
18°C – 27°C
Majesty palm, botanically Ravenea rivularis, is endemic to Madagascar, specifically found along riverbanks and in swampy, permanently wet valley bottoms in the island's eastern and central provinces, where it grows at elevations up to roughly 1,000 metres in gallery forests bordering freshwater river systems. It belongs to the palm family, Arecaceae, and the species epithet "rivularis" comes directly from the Latin for "of the streams," reflecting the plant's genuine and specific ecological dependence on consistent freshwater access — the species demonstrates a remarkable tolerance for waterlogged conditions in the wild, growing directly in standing or flowing water in ways relatively few other commonly cultivated palms can match. Madagascar itself is recognized as one of the world's most significant biodiversity hotspots, home to roughly 170 palm species found nowhere else on Earth, and Ravenea rivularis represents just one striking example of this island's extraordinary and highly localized plant diversity. The species is dioecious, meaning individual plants are either male or female, and it typically fruits in its native habitat between December and May, though fruiting is essentially never observed on plants kept as indoor houseplants, which are grown exclusively for their ornamental foliage rather than any expectation of flowering or fruit production.
In its native riparian habitat, majesty palm develops into a genuinely towering tree, with a solitary, pale gray, tapering trunk reaching 20 to 25 metres in height, topped by a crown of 10 to 15 gracefully arching, feathery fronds up to 3 metres long. This dramatic scale, however, is almost never approached by indoor-grown specimens, which typically max out somewhere between six and ten feet even under favorable conditions — a substantial and genuine gap between the plant's wild potential and its realistic indoor performance that reflects a broader, well-documented pattern with this particular species.
Confirmed non-toxic to cats, dogs, and horses by the ASPCA, making it a safe large statement plant for pet households.
Yes, it's confirmed non-toxic to pets by the ASPCA, making it a safe choice for a large indoor statement plant.
Every 5-7 days, keeping the soil evenly moist — unlike many palms, it doesn't like to dry out completely between waterings.
Usually low humidity or underwatering — this palm is naturally riverside-dwelling and needs consistently moist soil and higher humidity than most indoor palms.
