Buddleja speciossisima/ Buddleia speciossisima | Brazilian Butterfly Bush
*Seeds were collected late summer of 2025.
Buddleja speciossisima, which has not been given a common name and deserves one, we’ve appropriately named ‘Brazilian Butterfly Bush’. It’s a spectacular and extremely rare South American shrub native to a very restricted area of Southeastern Brazil’s high mountains, specifically the high altitudes (2,000–2,500 meters) of the Serra do Itatiaia mountains in Itatiaia National Park, where it grows in rocky grasslands. It has fuzzy, silvery-white foliage and is best known for its striking, long, tubular reddish-orange flowers with flared mouths that grow in woolly panicles, which are pollinated by hummingbirds and hawkmoths. It differs from many other American Buddleja species by having perfect (hermaphroditic) flowers and is self-fertile. Despite its tropical origins, Buddleja speciossisima is surprisingly hardy, surviving cold temperatures in places like southern UK gardens, the Pacific Northwest areas of the US, and Nothern France.
Plants can reach up to 10 ft in height, however in temperate home gardens typically grows as a fairly low, scrubby shrubs. Hardy to around 15-20° F, perhaps lower for shorter periods of time.
Seeds germinate with heat, humidity, and light. Do not cover tiny seeds with soil. Seedlings start out extremely tiny and grow slow, so the most delicate of care must be taken for the first few weeks. This is a slow growing species and is difficult to propagate via cuttings, too.
We are the only company in the world to currently offer these seeds, and they may very well have never been available publicly in the U.S. until now!
Buddleia speciossisima is very similar in appearance to Buddleia longiflora, which has lighter orange and even longer flowers and grows in Brazil on the Serra Caparao mountain in the same region.
