Blue Blossom
Montara Mountain~Montara, California USA
This is the hardiest and largest ceanothus. Each spring the highways of the West Coast display masses of Blue Blossom flowers. Plants can be grown in screens, in hedges, and against walls. Elk and deer browse the foliage. The shrubs form dense thickets after fires and logging. The scientific name, meaning "thyrse-flower," refers to the compact, branched flower cluster; thyrsus is the name of the staff, adorned with leaves and berries, that belonged to Bacchus, the Greek god of wine.

Coastal California Poppy
Coastal Bluff Trail~Half Moon Bay, California USA
On sunny days in spring, California Poppies, the state flower, often turn hillsides orange. Responsive to sunlight, the flowers close at night and on cloudy days. The spicy fragrance attracts mainly beetles, which serve as pollinators. Flowers produced early in the season tend to be larger than those later on. There are other species in California, but none has the conspicuous pink rim at the base of the ovary.
The genus is named after Dr. J.F. Eschscholtz who lived from 1793 to 1831. He performed duties as a surgeon and naturalist with Russian expeditions to the Pacific coast from 1815 to 1818.

Common Sunflower
Farmer John~Half Moon Bay, California 2023
The state flower of Kansas. Contrary to common myth, the heads of sunflowers do not follow the sun each day. However, developing flower buds and leaves do exhibit some phototropism. The plant has been cultivated in Central North America since pre-Columbian times; yellow dye obtained from the flowers, and a black or dull blue dye from the seeds, were once important in Native American basketry and weaving. Native Americans also ground the seeds for flour and used its oil for cooking and dressing hair. It was believed, in the 19th century, that plants growing near a home would protect from malaria. Seeds from cultivated strains are now used for cooking oil and livestock feed in the United States and Eurasia. Many variants have been developed, some with one huge head topping a stalk 9-16 ft (3-5 m) tall, others with maroon rays. Prairie Sunflower (H. petiolaris), found throughout the Great Plains and similar to the wild forms of Common Sunflower, has scales on the disc in the center of the head tipped by white hairs, easily visible when the central flowers are spread apart. Developed in a single large head variety by Russians.

Ice Plant
Coastal Bluff Trail~Half Moon Bay, California USA
This plant is quite iconic to the California Coast; along highways you see bright green carpets stretching wide next to the glistening ocean. You often see spots of hot pink, yellow or even purple as these flowers bloom. While the view may be lovely, their impact on our California dune ecosystems does not have the same effect. Although ice plant is supposed to help stabilize the soil, it’s actually pretty bad at that as well. With shallow roots and branches climbing over each other, it can become very heavy. This causes large mats of the ice plant to fall off of steep surfaces at once, taking nutrients and topsoil along with it.

Genus: Carpobrotus
Family: Aizoaceae
Category: angiosperm
PLANTS group: Dicot
https://en.wikipedia.org/wiki/Carpobrotus
https://www.calflora.org/app/taxon?crn=1660
Carpobrotus chiefly inhabits sandy coastal habitats in mild Mediterranean climates, and can be also found inland in sandy to marshy places. In general, they prefer open sandy spaces where their wiry, long roots with shorter side branches form dense underground network, which extends much further than above-ground prostrate branches. Plants thrive well in gardens, but readily escape to other suitable places. They can form wide-area ground cover over a sandy soil, which suppresses indigenous sand dune vegetation when introduced to a non-native area.
Naked Lady
Terrace~Half Moon Bay, California USA
Leaves of A. belladonna begin growing in early spring, or during late autumn. They last for a few weeks to a few months until they wither away, and a flower stalk will begin growing. When found in the wild, Amaryllis belladonna is pollinated by hawk moths and carpenter bees. The flower has a long-tubed, pale perianth, which fully expands at night. This flower will then release a sweet fragrance, that contains acyclic terpenoid alcohol, linalool and abundant nectar, that attracts pollinators to it

San Mateo Tree Lupine
Montara Mountain~Montara, California USA
Lupines were once believed to be "wolf-like," devouring soil nutrients (the genus name comes from Latin lupus, meaning wolf). In fact, they "prefer" poor soil, which they do not further deplete. Tree Lupine, one of the most handsome species in the genus, grows rapidly, and its deep roots make it an effective and beautiful stabilizer of shifting coastal dunes; portions of San Francisco that were once unstable sand were reclaimed by Tree Lupine. However, its effectiveness at stabilizing coastal dunes has led to its introduction and subsequent invasion of areas north of San Francisco Bay where the species has pushed out native species and formed monocultures. The California Invasive Plant Council has declared Tree Lupine an invasive species outside its native range.

Alula
Limahuli Gardens Hanalei, Kaui, Hawaii USA 2024
Once found mostly on windswept sea cliffs of Kauaʻi (Nā Pali Coast, Hāʻupu Ridge, Nāwiliwili) and most likely extinct on Niʻihau (Kaʻali Cliff). Ālula experienced a serious set back in 1992 when Hurricane ʻIniki destroyed half the natural population (60 to 70 plants) along the Nā Pali Coast on Kauaʻi. The combined hurricanes of ʻIwa (1982) and ʻIniki destroyed 10 of the remaining 12 individuals in the Hāʻupu area. [1]. Locations where the last populations are known to exist on the Nā Pali coast were searched. Only one ālula is known to remain in the wild. [Ken Wood, National Tropical Botanical Gardens]

History
The first European to describe these plants was Philibert Commerçon, a botanist accompanying French Navy admiral Louis Antoine de Bougainville during his voyage of circumnavigation of the Earth, and first published by Antoine Laurent de Jussieu in 1789.[
The small, tubular, whitish, 5 to 6-lobed flowers are surrounded by 3 colorful, papery, triangular to egg-shaped, petal-like floral bracts. The leaves are green or variegated with yellow, cream, or pale pink, alternate, and egg-shaped, elliptic, or heart-shaped. The mature branches are woody, brittle, and have slender spines at the leaf axils. The plants are climbing or straggling.

Halaakala Silversword
Haleakala Crater Maui, Hawaii USA 2009
The Haleakalā silversword, Argyroxiphium sandwicense subsp. macrocephalum, has numerous sword-like succulent leaves covered with silver hairs. Silversword plants in general grow on volcanic cinder, a dry, rocky substrate that is subject to freezing temperatures and high winds. The skin and hairs are strong enough to resist the wind and freezing temperature of this altitude and protect the plant from dehydration and the sun.
The silvery hairs, fleshy leaves, and low-growing rosette form of the Haleakalā silversword (Argyroxiphium sandwicense subsp. macrocephalum) allow it to survive in hot, dry climates like the aeolian desert cinder slopes of the crater. Silverswords live between 3 and 90 years or more. They flower once, sending up a spectacular flowering stalk, and then die soon afterward, scattering drying seeds to the wind.

Hibiscus Mao hau hele (State Flower)
Hanalei Wildlife Refuge, Kauai, Hawaii USA 2011
Hibiscus brackenridgei A.Gray – maʻo hau hele ("hau most similar to maʻo") is a tall shrub (up to 10 m or 33 ft) with bright yellow flowers, closely related to the widespread H. divaricatus. Two subspecies are recognized: H. b. ssp. brackenridgei, a sprawling shrub to an erect tree found in dry forests and low shrublands at elevations of 400–2,600 ft (120–790 m) above sea level on Molokai, Lanai, Maui, and the island of Hawaii;[4] and H. b. ssp. mokuleianus, a tree from dry habitats on Kauai and the Waianae Range on Oahu. This species is listed as an endangered species by the USFWS. The yellow flower of this species was made the official state flower of Hawaii on 6 June 1988,[5] and although endangered in its natural habitats, has become a moderately popular ornamental in Hawaiian yards.
The flowers are 4 to 6 inches (10 to 15 cm) wide and have 5 crinkled, egg-shaped petals, a yellow staminal column with a small, 5-lobed style and yellow to reddish anthers all along the length of the column, and 7 to 11 hairy, green, linear to awl-shaped bracteoles below the flowers. The flowers either have a solid red center or just have small splotches of red at the base of each petal. The flowers are followed by beaked seed capsules. The leaves are green, alternate, toothed, finely hairy to almost hairless above, and fuzzy below. The mid-plant leaves are either egg-shaped or have 3 to 7 palmate lobes like a maple leaf. The upper leaves are more lanceolate to oblanceolate in shape. The branches are smooth to wrinkled and spineless or covered with pustule-like spines.

Hibiscus Pua Aloalo
Limahuli Gardens Hanalei, Kauai, Hawaii USA 2011
The native plants in the genus Hibiscus in Hawaii are thought to have derived from four independent colonization events for the five endemic species (four closely related species plus the yellow-flowered species) and one each for the two indigenous species.
Hibiscus arnottianus subsp. immaculatus is a shrub or small tree generally 8 meters in height, though individuals may reach 10 meters tall. The leaves are oval with a smooth upper surface and smooth or slightly round-toothed edges. The leaves are 4 to 10 centimeters long and often have red veins and stems. The faintly fragrant flowers have white petals 8 to 11 cm long, 2.5 to 3.5 cm wide, with the calyx being 2.5 to 3 centimeters long. Anthers are arranged along the upper third of the white staminal column 10 to 14 cm long. This subspecies is distinguished from the other native Hawaiian members of its genus by its white petals and white staminal column. The flowers may be slightly pink or may age to pale pink.

Closely related to the Haleakala silversword (Argyroxiphium sandwicense subsp. macrocephalum) and in the family Asteraceae, the Mauna Kea silversword is a member of the silversword alliance, a group of approximately 50 species in three genera, all endemic to the Hawaiian islands. Their diverse morphologies belie extremely close genetic kinship and suggest extremely rapid evolution from a single precursor species.[7][8] The silversword alliance is considered the most dramatic example of adaptive radiation among plants in Hawaii, illustrating the role of isolation and distinctive ecological conditions in promoting evolution

Plumeria
Limahuli Gardens Hanalei, Kauai, Hawaii USA 2011
In Hawai`i, Plumeria rubra produces flowers before the leaves emerge at the beginning of summer and has a flowering peak from April through to September. The original trees introduced to Hawai`i had white flowers with yellow centers, however subsequently trees with red flowers have also been introduced. Breeding programs have crossed trees with different colored flowers to produce a wide range of color varieties of this species: red, pink, or white flowers can be seen with flowers frequently either a single color or with a yellow or pink splash of color in the center. The flowers produce nectar which has a strong lemon scent. The fruit of this species is a dry follicle which splits along one side to release many winged seeds.
The flowers are in rounded, bouquet-like clusters at the branch tips. The individual flowers are tubular, 3 inches (8 cm) across, and have 5 white, blunt-tipped, spreading lobes and a yellow center. There is no tinge of red anywhere on the flowers or the flower buds. The flowers are sometimes followed by dry, brown, linear-oblong seed follicles containing numerous winged seeds. The leaves are shiny dark green above, paler green and prominently veined below, leathery, and narrowly egg-shaped with a distinctive rounded tip. The leaves are clustered near the tips of the thick, fleshy, knobbly, brown branches.
