Trevesia palmata
snowflake aralia, snowflake tree
Highlight Month:
August
Nativity:
Trevesia palmata belongs to the ginseng family, or Araliaceae, and has a large native range from Nepal to China and south to Thailand and Vietnam.
Growth Habit:
Individual leaves can reach up to two feet wide and are circular in outline. As the plant matures, successive leaves change their morphology from simple to palmate and, in some selections, the leaves display attractive dissected sinuses. The common name references this highly variable and cut-leaf foliage in the pattern of a snowflake. The cultivar ‘Micholitzii’ is one of these horticultural selections chosen for dramatic leaf shape and fuzzy white newly emerging foliage. Trevesia palmata grows in evergreen forest understory typically as a solitary trunk with few side branches, reaching a maximum height of 15-20 feet tall. The stems and petioles have scattered short prickles.
Growing Requirements:
T. palmata prefers light shade to part sun and is hardy to USDA Zone 9.
Features:
Like many other species in the Araliaceae, Trevesia palmata produces its reproductive structures on an umbel. Short flower stalks gathered in a cluster resemble spokes on an umbrella. Flowers on the ends of the stalks emerge yellow in the spring and mature into half-inch round fruits. The young flower buds are edible. The genus Trevesia contains eight species, all native to Asia. Other well-known genera in this family include Aralia, Cussonia, Fatsia, Hedera, Pseudopanax, Heptapleurum, Schefflera, and Tetrapanax.

Acanthostachys strobilacea
pinecone bromeliad
Highlight Month:
July
Nativity:
This odd genus of bromeliads contains only three species, all endemic to South America. In its native habitat, it grows epiphytically or on rocks from eastern Brazil to Paraguay and northeastern Argentina.
Growth Habit:
It is a low maintenance, drought tolerant plant that spreads via short basal rhizomes.
Growing Requirements:
The long narrow foliage is covered in tiny specialized white scales called trichomes and initially grows upright and then arches and becomes pendulous, making it an excellent subject in a hanging basket or tall pot.
Features:
A. strobilacea blooms in the summer with small, dense inflorescences reminiscent of tiny pinecones. The flowers have yellow petals and are set inside showy bright orange and red pointy bracts. The genus name is derived from the Greek, acanthos (thorny or spiny), and stachys (a flower spike). The specific epithet, strobilacea, also refers to the cone-like appearance of the persistent inflorescences.
Lotusland is home to one other species in this genus, Acanthostachys pitcairnioides, which exhibits a much different growth habit with upright, bright orange leaves lined with dark brown teeth. Its lavender flowers emerge at the base of each rosette and develop into attractive ovoid white fruits.
Where at Lotusland:
Acanthostachys strobilacea can be found in the Lower Bromeliad Garden at Lotusland where it happily grows in a terra cotta strawberry pot.

Deuterocohnia brevifolia
Highlight Month:
June
Nativity:
D. brevifolia is native to southern Bolivia and northwestern Argentina.
Growth Habit:
There are approximately seventeen species of Deuterocohnia, all bromeliads native to South America. A small group of these species grows in dense cushion-like mounds amongst rocks or terrestrially in the ground. These mounds form from continuously branching stems, or ramets, and can reach several feet in width. Branching usually occurs after an individual rosette has flowered and new ramets form out of the upper part of the flowering rosette. The older, interior ramets form a spongy mat that eventually decomposes but stores water and decomposing nutrients.
Deuterocohnia brevifolia is one of the most cultivated of the genus and flowers in winter to spring with sparse tubular chartreuse flowers. It is closely related to the red-green flowering Deuterocohnia lotteae. The small rosettes of leaves range in size from 1-2.5 inches in diameter, have varying amounts of teeth on the margins, and are covered in small silvery scales called trichomes.
Growing Requirements:
Requires well-drained soils and full to part sun.
Features:
Deuterocohnia brevifolia is one of the most cultivated of the genus and flowers in winter to spring with sparse tubular chartreuse flowers. It is closely related to the red-green flowering Deuterocohnia lotteae. The small rosettes of leaves range in size from 1-2.5 inches in diameter, have varying amounts of teeth on the margins, and are covered in small silvery scales called trichomes.
The genus name is dedicated to the German botanist and microbiologist Ferdinand Julius Cohen (1828-1898) who already had the genus Cohnia, named after him. Deuteros, from the Greek for second, designates Deuterocohnia as the second genus named in his honor. The specific epithet, brevifolia, comes from the Latin brevis = short, and folium = leaf.
Where at Lotusland:
D. brevifolia, and several other Deuterocohnia species, can be found in the Lower Bromeliad Garden at Lotusland.

Graptopetalum paraguayense ssp. bernalense
Highlight Month:
May
Nativity:
This diminutive succulent is known from only one location and was first introduced to the botanical field in 1979 by Alfred Lau (1928-2007), a German plant collector and missionary living in Mexico. Lau found the plant at 700-800m on Cerro del Bernal, a solitary mountain peak located 39 km east of Ciudad Mante, Tamaulipas, Mexico. It was observed growing in both rock fissures and on flat ground amongst Sedum, Echeveria, Tillandsia, Ficus, and several orchid species.
Growth Habit:
The one other subspecies, G. paraguayense ssp. paraguayense, has only ever been observed in cultivation when volunteer seedings appeared in the New York greenhouse of Frank Weinberg in 1904, likely traveling as seed amongst cacti imported from Mexico. After much taxonomic and nomenclatural confusion, it retains the specific epithet, paraguayense, despite its likely origins in Mexico, not Paraguay.
G. paraguayense ssp. bernalense differs by having a smaller overall size and yellowish to whitish green leaf coloration versus the larger rosette and greyish violet color of ssp. paraguayense.
Growing Requirements:
Sun, well-drained soils
Features:
The genus Graptopetalum comes from the Greek grapto, “to write,” and petalum, “a petal,” referencing the marked or inscribed petals often colored with red in some of the species. Graptopetalum flowers face upwards and spread out like tiny stars. There are approximately sixteen Graptopetalum species recognized with the majority occurring in Mexico and two into Arizona. As of 2012, botanical researchers in Russia have suggested elevating G. paraguayense ssp. bernalense into its own species, G. bernalense.
Where at Lotusland:
Lotusland is home to both subspecies in the “echeveria circle” in the Succulent Garden. Our ssp. bernalense came from the original collection by Lau, donated through the International Succulent Introductions through The Huntington (ISI 1660, HBG 42730). Our ssp. paraguayense originated from the late John Bleck, former greenhouse manager at UCSB and owner of Abbey Garden succulent nursery, and distinguished Santa Barbara plantsman.

Euphorbia makallensis
sausage plant, hamat kolkwal
Highlight Month:
April
Nativity:
E. makallensis is native to the Tigray Region of northern Ethiopia where it is found in only two locations. The first recording, near Igre Hariba, was documented in 1975, and a second population was later found in 2011, 75km north in Hawzen.
Growth Habit:
This compact euphorbia is easy to grow and makes a great statement plant as a potted specimen or in the ground. In the wild, E. makallensis can form tuffet-like mounds up to five feet wide, resembling large rocky outcrops from a distance. At first glance, it resembles a miniature version of Euphorbia resinifera from Morocco. The stems of this plant are usually four-sided, edged with grey spine shields along the entire length, and produce spines in pairs of two. Flowering occurs in the late spring/early summer with bright yellow floral parts arranged in a unique structure called a cyathium.
Growing Requirements:
Well-drained soils, full sun.
Features:
Although this species had been in cultivation for some time, it wasn’t officially described as a new species until 1981 by researchers at Kew Gardens. The local Tigrinya name for this species is “hamat kolkwal” meaning “the mother-in-law of kolkwal,” in reference to the larger Euphorbia candelabrum.
Where at Lotusland:
E. makallensis can be found on the euphorbia side of the Main Drive at Lotusland near the entrance to the Water Garden.

Magnolia x soulangeana
saucer magnolia
Highlight Month:
February
Nativity:
Garden Origin
Growth Habit:
This deciduous magnolia may grow as a multi-trunked or single-stemmed bush. It usually grows 10 to 15 feet in height. Flowers appear in early spring before the glossy green leaves.
Growing Requirements:
While perfectly happy in our Mediterranean climate, this magnolia will also thrive in temperate climates. Likes regular water and rich, well-amended soil.
Features:
The showy flowers are cup shaped, reddish purple on the outside shading to nearly white on the inside. It is a hybrid of Magnolia denudata and M. liliiflora.
The original Magnolia x soulangeana cross originates from France, where it was originally bred by plantsman Étienne Soulange-Bodin, and first flowered in 1826. Over fifty cultivars of Magnolia x soulangeana exist today.

Camellia ‘Minato-no-akebono’
Minato-no-akebono hybrid camellia
Highlight Month:
January
Nativity:
Garden Origin
Growth Habit:
This plant’s understated pink flowers have 5-7 notched petals with darker coloration towards the petal tips. They are borne profusely on this upright shrub from December to March. The entire plant has an open branching habit and can reach 5-9 feet high and 4-8 feet wide.
Growing Requirements:
Prefers regular water, full to part shade, and well-drained soils. It is hardy to USDA Zones 7-10.
Features:
The simple, light pink flowers may appear small on this camellia, but this winter-bloomer is highly scented, perfuming the air around it on a warm winter day with a spicy-sweet aroma. Camellia ‘Minato-no-akebono’ is a hybrid of Camellia lutchuensis, the source of the fragrance, and Camellia japonica ‘Kantō-tsukimiguruma’, adding increased cold hardiness and pink flower coloration. It originates from Yokohama, Japan where it was hybridized by Masaomi Murata in 1981 and officially registered in 1989. The cultivar name translates to “harbor at dawn.”
Where at Lotusland:
Camellia ‘Minato-no-akebono’ can be found in Lotusland’s Japanese Garden near the Torii Landing.

Aloe tororoana
Tororo Rock aloe
Highlight Month:
December
Nativity:
SE Uganda
Growth Habit:
Aloe tororoana grows on bare rocky slopes with decumbent stems. It is a perfect candidate for a small garden or container as it does not take up a lot of space. The leaves are a distinctive milky-green color and are covered in small white spots. Flowers are borne on 18-inch racemes, are coral-red with green tips, and appear in fall/early winter in Santa Barbara.
Growing Requirements:
Well-drained soil, sun
Features:
This species was originally described by Gilbert Westacott Reynolds in 1953 from Peter René Oscar Bally’s 1952 collection off Tororo Rock in SE Uganda. Originating over 250 million years ago, Tororo Rock is a volcanic plug created by hardened magma inside the vent of an active volcano. The now eroded remains are an iconic feature and tourist attraction in the town of Tororo. Additional populations of Aloe tororoana have recently been located in the nearby Osukuru Hills, as mentioned in the 2017 field guide, Aloes of Uganda by Thomas Cole and Tom Forrest. These outlying populations are under increasing threat due to phosphate mining, rock quarrying, and land clearing for housing and livestock grazing. A. tororoana is currently listed as Vulnerable by the International Union for the Conservation of Nature.
Where at Lotusland:
This species can be found in the Aloe Garden at Lotusland which houses two accessions, both of which are presumed propagations from the original 1953 Bally & Reynolds collection from the type locality.

Begonia angularis
Highlight Month:
October
Nativity:
South and SE Brazil
Growth Habit:
This species blooms sparsely in the upper leaf axils from winter to spring with white flowers. The leaves are a soft grey-green with attractive pale grey venation and occasional reddish undersides. The plant can reach over 8 feet tall in the landscape and is in the “cane-like” category, producing multiple stems from the base. Pinch the growing tips of tall stems to give it a bushier appearance. The specific epithet, angularis, references the uniquely angled stems with six prominent ribs, a defining characteristic of this species.
Growing Requirements:
Considered an excellent choice for the beginner begonia grower, B. angularis prefers shade, moist soils, and can be grown outdoors in Santa Barbara.
Features:
Begonia angularis is native to the Atlantic coastal forest of Brazil, an incredibly diverse region under threat due to ninety percent of the area being heavily fragmented by human activity. Almost two hundred Brazilian Begonia species occur in this cool, moist upland strip along the Atlantic Ocean, with only a few found in the adjacent Amazonian rainforests. This species was first described by Italian botanist Guiseppe Raddi in 1820 and introduced into European horticulture in 1845.

Phanera yunnanensis
climbing Chinese orchid vine
Highlight Month:
October
Nativity:
South-Central China, Myanmar, and Thailand
Growth Habit:
This vining plant in the legume family comes from China, Myanmar, and Thailand and displays light pink flowers from late summer into fall. Vines reach 15-20’ long and require a structure or another plant to climb on.
Growing Requirements:
They prefer part to full sun for best flowering, are tolerant of drought once established and are hardy to USDA Zone 7b.
Features:
After decades of taxonomic reshuffling and reorganization of the subfamily Cercidoideae, 82 species have now been placed in the genus Phanera. P. yunnanensis was previously in the genus Bauhinia and continues to be sold as such at nurseries. Phanera are separated on the basis that all are vines or lianas (woody vines) with tendrils, have a lobed calyx, have 2-3 fertile stamens, and are distributed across Asia and Australasia.
