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.

Eucalyptus megacornuta
warted yate, big-horned eucalyptus
Highlight Month:
December
Nativity:
E. megacornuta has a very limited range in the southwest of Western Australia near the Ravensthorpe Range. The population is estimated at less than 1,000 individuals and is listed as Vulnerable by the IUCN.
Growth Habit:
E. megacornuta is a great tree for small spaces, reaching only 30’ high and 15’ wide. The bark is smooth and mottled with grey, green-grey, and orange peeling strips. The leaves are evergreen, lanceolate, and contain oil glands. It is hardy to USDA Zones 9-10. This species is considered a mallet, a small form of eucalypt from Western Australia. Mallets are single stemmed, have steeply angled branches, and lack the regenerative structures of a lignotuber and epicormic buds.
Growing Requirements:
Full sun to partial shade, well-drained soils, drought tolerant once established.
Features:
This showy eucalyptus displays large chartreuse to yellow stamens over a long period from winter to summer. Flower buds are temporarily concealed by a two-inch warty cap called an operculum, resembling a monstrose fingertip. They are borne in clusters of 3-7 on a flattened woody peduncle. The flowers produce abundant nectar for pollinators and the fruits later mature into a woody capsule containing the seeds. Both the opercula and capsules can be used in dried arrangements or for art projects.
The genus name comes from the Greek, eu (well) and kalyptos (covered), referring to the operculum. The specific epithet, megacornuta, means large-horned, also referencing this same structure.
Where at Lotusland:
There is one E. megacornuta specimen at Lotusland in the Australian Garden, near the Cold Spring Gate entrance. The tree was grown from seed by Cameron Hannah-Bick, UCSB Greenhouse Manager, and donated to Lotusland in 2018.

Xanthorrhoea quadrangulata
Australian grass tree
Highlight Month:
December
Nativity:
South Australia
Growth Habit:
Grass-like foliage covers its thick woody trunk that can reach 6’ tall. Mature plants produce a 6-12’ stalk bearing small white fragrant flowers in the spring. Slow-growing.
Growing Requirements:
Full sun, drought tolerant.
Features:
The scientific name is derived from the Greek ‘xanthos’ (yellow) and ‘rheo’ (to flow), in reference to the resin exuded out of the trunk. The resin is used by Aboriginal Australians for spear-making, patching, and as a varnish. The specific epithet comes from the Latin ‘quadra’ (four) and ‘angulata’ (angular), describing the four-sided cross section of the leaf.

Ilex cornuta ‘Burfordii’
Burford holly
Highlight Month:
December
Nativity:
Ilex cornuta is native to East Asia; ‘Burfordii’ is a cultivar developed from a sport discovered on a plant growing in a Georgia cemetery around 1900.
Growth Habit:
A tree to 15 ft tall and 10 ft wide. It naturally forms a dense shrub, but can be pruned into a small tree by removing the lower limbs. It is easily shaped, and can even be espaliered along a wall.
Growing Requirements:
Full sun or partial shade with regular watering. It is adaptable to different soil types, and is drought-tolerant once established.
Features:
Burford holly has glossy dark green leaves with only one spine on the tip. The small white flowers are not an important ornamental feature, but are followed by clusters of large red berries in fall that last for months. Unlike some types of holly, Burford holly is self-fertile and a single plant will have prolific fruit.
Where at Lotusland:
There are two specimens growing in the Arboretum, an area between the Aloe Garden and the Japanese Garden which has many unusual trees and shrubs.

Nandina domestica
Heavenly Bamboo, Sacred Bamboo
Highlight Month:
December
Nativity:
China and Japan
Growth Habit:
A multi-stemmed shrub up to 8 feet tall, speading outward by underground runners.
Growing Requirements:
Nandina will grow in sun to light shade, and is adaptable to moist or dry soil. It is very hardy and resistant to oak root fungus, as well as most pests.
Features:
Although not related to bamboo, it has the same lacy, fine-textured foliage. The leaves are pinkish when young, then turn green when mature and finally bronze or red in autumn. Fall color is best in sunnier locations. Clusters of small white flowers are followed by bright red berries, though plants may have both fruit and flowers at the same time. There are many cultivars with variations of height, flower, and berry color.
Where at Lotusland:
There are over eighty Heavenly Bamboo growing in the Japanese Garden.

Berberis oiwakensis (syn. Mahonia lomariifolia)
Chinese holly
Highlight Month:
December
Nativity:
South-central China, Hainan, Myanmar, Taiwan, and Tibet
Growth Habit:
This architectural Berberis has it all! Long bluish-green leaves with 19-37 leaflets emerge atop corky 6-12’ stems. Fragrant bright yellow flowers appear in winter followed by edible powdery blue berries in spring, much beloved by birds. It makes a great statement in a tropical or woodland garden, even when not in bloom.
Growing Requirements:
This plant prefers moist, well-drained soils, part-shade, and is hardy down to USDA Zone 8, and possibly Zone 7 with minor damage.
Features:
There is significant debate over the correct name of this species with all Mahonia species now incorporated into the genus Berberis. The featured plant was long known as Mahonia lomariifolia, referencing the leaves appearing similar to the fern genus Lomaria (now Blechnum). B. oiwakensis is one of the parents of the B. × hortensis (Mahonia × media) hybrids, most popular being ‘Charity’ and ‘Winter Sun’.
Where at Lotusland:
Berberis oiwakensis can be found in the Japanese Garden and across the main drive in the Tropical Garden at Lotusland.

Laelia anceps
Highlight Month:
December
Nativity:
Mexico to Honduras
Growth Habit:
This orchid species grows epiphytically on trees. Specimens may be mounted directly on the trunk of a suitable tree or attached to a plank and hung in the garden.
Growing Requirements:
Laelia anceps should be positioned in light to moderate shade. Established plants can withstand some drought, but do best when watered regularly. Bloom production can be enhanced by monthly applications of dilute liquid fertilizer.
Features:
Laelia anceps is one of the easiest orchids for outdoor culture in Southern California. It survives temperatures as low as 22° F and does not mind hot summers.
Where at Lotusland:
There is a large hanging specimen in the Upper Bromeliad Garden.
