Pluchea carolinensis is also known as sourbush and cure-for-all. This latter name probably comes from its medicinal use in its native range, which is the tropical Americas. It’s a member of the aster family – Asteraceae.
The plant was first reported in Hawaii in 1931 and on the Big Island in 1933. It’s believed to be an accidental introduction, possibly associated with shipping to Hawaii and within the islands. The onset of World War II prompted the plant’s spread through the Pacific, probably in military shipments.
On the Big Island it’s most often seen in drier coastal areas, but it can tolerate a variety of climates and conditions. These photos were taken on the Puna Coast Trail in Hawaii Volcanoes National Park.

Calotropis procera, also known as Apple of Sodom, is a member of the milkweed family. A native of parts of Africa and Asia, it’s another of the many invasive plants that have found a home in Hawaii. On the plus side, it’s a host plant for Monarch butterfly caterpillars, while the butterflies themselves feed on the flowers.
In these photos, you can see the leaves, flowers, and the large green fruits of the plant.
Halemaumau Crater, at the summit of Kiluaea Volcano, underwent profound changes during the 2018 eruption. When lava drained from the summit vent, the crater floor experienced a series of collapses, radically changing the appearance of the crater and its surrounds.
I had seen this area from the air and posted about it (here). The middle photo was taken during that flight and shows where a section of Crater Rim Drive slid into the crater. When I last visited the park, I got a different view of this.
The recently reopened Byron Ledge Trail has good views across the crater. In the top photo, the chunk of road is clearly visible with its white line running down the middle of it. The bottom photo shows the longer view across the crater with the road in the distance. In the center of the photo, equipment used to monitor the volcano’s activity, can be seen. The tree in the foreground is an ‘ōhi‘a lehua with its brilliant red flowers. It’s an early colonizer of new lava flows and all those little dark spots on the main crater floor are ‘ōhi‘a lehua trees, mostly still shrub-sized at this time.

There’s a very large mango tree in the yard, which is an erratic producer of fruit. Some years, there’s not much. Other years, the tree looks like an overdecorated Christmas tree. In those times, it’s best not to spend much time under the tree, particularly when it’s windy, because the thud of fruit hitting the ground is frequent (though, standing under that tree is risky any time, since large branches are prone to breaking off).
When fruit does start to fall, wild pigs move in. There are always windfalls available and the pigs love this easily-accessed treat. The pig population around here varies, mostly depending on whether hunters are active in the area. Pigs are nocturnal, so do most of their foraging at night, but the younger ones are more likely to venture out in daylight hours, either because they haven’t yet learned how dangerous that is, or because it’s harder for them to get a look-in when the big pigs are around.
This year, there have been as many as nine pigs in the yard at one time, but this younger pig was out by itself. As there were quite a few mangos on the ground, it was being quite choosy as to which ones to eat. Hard ones will be shunned, unless that’s all there is. This mango was just right, and the pig was tucking in until something disturbed it and it ran off, but not without its prize.
Mostly the pigs are a source of entertainment and don’t bother me. The exception is when they roam past the bedroom window in the middle of the night and get into arguments, grunting and squealing. They also have a very ripe smell, which drifts in through the open window. Fortunately, they’re easy to disperse. I just do my large, angry dog impersonation, consisting of a few loud barks, and they disappear like they’ve been shot out of a cannon.
This evergreen tree, also known as Natal Plum, hails from South Africa. The fruit is edible and the flowers fragrant. In Hawaii, it’s also grown as a hedge, particularly in coastal areas, as it tolerates both salt and wind.
This drynaria rigidula ‘Whitei’ basket fern was growing on a tree trunk at Hawai’i Tropical Botanical Garden (which has since change its name). I like basket ferns, which look like upturned umbrellas. This fern was complemented by a dinema polybulbon orchid, a delicate and fragrant epiphytic orchid that was winding it’s way up into the fern.
