beautiful volunteer flower
#11
if its the hibiscus, which I hope it is, here is the info from the Manual...



5. Hibiscus furcellatus Desr.
[H. f. var. youngianus (Gaud. ex Hook. & Arnott) Hochr.; H. youngianus Gaud. ex Hook. & Arnott]
(ind) 'Akiohala, 'akiahala, hau hele, hau hele wai

Coarse perennial herbs or subshrubs 1-2.5 m tall, young branches, petioles, and pedicels densely stellate pubescent and often (in all Hawaiian collections) also with setose, pustulate-based, simple hairs 0.5-2 mm long. Leaf blades ovate or sometimes orbicular in outline, 5-15 cm long and wide, unlobed or shallowly and angulately to deeply 3-lobed or 5(7)-lobed, midvein on lower surface with a basal gland, both surfaces stellate tomentose and sometimes setose on veins, margins glandular serrate to glandular dentate, base cordate, stipules filiform, 4-8 mm long, caducous, leaving an elliptic scar. Flowers solitary in the upper leaf axils or in racemes, pedicels stout, 1-2 cm long, not articulate but deciduous at point of insertion; involucral bracts usually 10-14, linear, 10-15 mm long, apex bifid; calyx 1.8-2.5 cm long, up to 4 cm long in fruit, stellate pubescent and hirsute with simple hairs, especially on the 10 prominent veins, median vein of each lobe with an elongate gland above the middle; petals apparently not opening widely, pale magenta to rose, more deeply colored at base, 5-9 cm long; staminal column included, maroon, antheriferous from near base. Capsules ovoid-apiculate, enclosed by the calyx, 2-2.5 cm long, thin-walled, hirsute. Seeds 2.4-2.8 mm long, glabrous or papillate. [2n = 72.] Indigenous to primarily marshy or low places near sea level in the West Indies, Florida, Central and South America, and apparently also in Hawai'i; in Hawai'i occurring primarily in wet, disturbed areas, 90-240 m, on Kaua'i, O'ahu, Maui, and Hawai'i. However, Sinclair (1885) states that it was once common "in nearly all valleys and sheltered places" on both windward and leeward sides of the islands. - Plate 124.

The association of the Hawaiian populations with Hibiscus furcellatus follows Menzel, Fryxell, and Wilson (1983). Hawaiian collections of the species have copious, simple-pustulate hairs on the stems, a feature apparently lacking or poorly expressed elsewhere. Plants collected on Hawai'i (Big Island) often have deeply lobed leaves, but on the other islands the leaves are usually angled or shallowly lobed, as is typical of the species.

It would be easiest to identify if you could get a photo?

Several kinds of Tibouchina: the cane variety is narrowly upright with small flowers, while the multiflora can be a large shrub with 2-3" flowers. Both very invasive.

Bananahead, this is fabulous! I think those are my plants! I have them all over. If they are rare, how did this happen? How rare are they? I'll try and seed them throughout my property, and I'll bring some to Hilo also. I just let stuff grow because I dont like using chemicals and now things are in flower.

'Akiohala
they are not rare overall, over all the islands, just scarcer in Puna now, they used to grow all along the wetter lowlands before all the invasive stuff showed up over last 235 years and pushed them out a bit.... beside Ohia there is prob not another native flowering plant in most yards in Orchidland... so thats lucky you have these, they like disturbed sunny areas that get rain. 'Akiohala is the only native hibiscus that will grow to full size in one season, they are fast growers growing to full size and flowering in 1-2 years and they have alot of seeds (very prickly brown seedpods, use gloves), I have about 100 2" seedlings right now and its just from 2-3 seed pods I collected about 5 months back.
I went back and looked at some of my full grown 2-3 year old ones and they do have 5 lobed leaves on mine that are from seeds collected, the ones I have from cutting from a plant only 10' from the hwy near the Keaau Dump (now gone because of construction) has only heart shaped leaves.... it may be possible the older they get the less lobed the leaves get, the one killed by construction was at least 8-10' tall and large at the base from many years of being hit by that arm mower that trimmed the hwy. PS. I can easily ID these at 60+ MPH Smile

in the future, the plants on the Big Island and in Hawaii in general may become an endemic subspecies because of the evolved differences from the central American type ie very hairy/prickery and lobed leaves

Thanks so much bananahead for the links. Maybe some of your seeds wafted down to Orchidland and grew on my lot! Anyhow, I'll definately bring these to my yard in Hilo and plant them there too. Gardening in Hawaii is so much fun!

Went out there today and looked again. They are definately hibiscus. I have at least 20 of them. No clue how they got there.

UK - you did take the hibiscus starts I had (most were the pinks from my neighbors trimming), but I really doubt they are them, unless you have a super lot to get them 4' already!

if anyone wants to see this type of native pink hibiscus up close (Hibiscus furcellatus), there is one near the end of the loop trail at Lava Tree Park (the end if you go counterclockwise)... its next to a cyclone fence on the left side, a sprawling older bush that is sometimes 1/2 dead looking but has alot of seeds at times
dont look for what many think is a normal hibiscus, these plants look different and grow much differently (faster)

in same park... there are also many trees of the Hawaii state flower, an endemic hibiscus called Ma'o Hau Hele (Hibiscus brackenridgei), it has yellow flowers and maple or grape type leaves... an endangered species

both of these types of native hibiscus are often called 'hearty hibiscus', because they like drier hotter temps than the common ornamental tropical types..., grow faster live shorter lives, and look far different too with fuzzy hairy leaves etc.
