Southern Mexico and Central America
The stems of this bamboo grow in a tight clump. They shoot straight up for 15 feet or so and as the leaves open, the whole culm will arch down toward the ground. Where it touches the ground, an individual stem can form roots and thus a new plant. Leaves occur in whorls along the stems.
This species will grow in sun or partial shade with moderate water. It is hardy only to about 28 degrees and does not do well with extreme heat.
The fluffy appearance of the leaves and graceful arching culms make this plant highly ornamental

Parts of Serbia and Montenegro
This ground-hugging perennial grows by stems that creep along the soil, rooting as they travel. Eventually, it can cover a large surface area. It will also climb up rocks and taller plants that have a rough surface for it to hold on to.
Serbian Bellflower thrives in shaded or semi-shaded woodlands and is hardy to about 40° F. It requires consistent water, especially in warmer months.
The dainty, star-shaped blue flowers brighten the shady gardens that it grows in.

Nymphaea ‘Madame Ganna Walska’
This waterlily is in the group known as tropicals. These species and selections only thrive in the tropics or ponds that are warm year round. Only reluctantly can they be coaxed into going dormant and in cool weather climates, they typically are grown as annuals.
All waterlilies are rooted in soil and in cultivation in ponds are grown in large planting containers filled with soil containing no organic material. Most are heavy feeders and require plenty of balanced fertilizer to grow lushly and bloom well. Tropical waterlilies may be over-wintered in heated tanks, if available.
This pink-flowered selection was bred by hybridizer Jack Wood and named for Madame Walska (pink was her favorite color). It also has striking maroon variegation on the leaves.

Medium sized rosette of narrow, recurved leaves, two to three feet across. The wavy margins are dotted with soft spines. Overall appearance is chalky gray.
Agaves generally require well-drained soil and full sun. Although this species is native to regions with calcareous soils, it will do well in most soil types.
Like all agaves, this species flowers at the end of an individual plant’s life cycle. The very tall inflorescences bear bright orange clusters of flowers that produce copious nectar. Although the mother plant dies after flowering, many “pups” or offsets are produced at the base.
Just off the driveway on the path leading down to the water garden.
Hardy and tropical waterlilies grow in lakes and ponds in shallow water from 2 to 6 feet deep. Hardy types go dormant and remain in the pond year round. Tropical varieties are mostly treated as annuals outside the tropics, although they may be over-wintered in a warm tank.
Waterlilies are rooted in the mud in nature, so they require planters or pots in a water garden. Use good soil without organic amendments and plant in full sun.
Waterlilies provide a nearly unlimited spectrum of colorful flowers in the water garden. Hardy varieties occur in white, pink, red, yellow and shades of orange. Tropicals are more electric and include the above colors as well as blue and purple. There are some tropical varieties that bloom at night, opening in late afternoon and closing by mid-morning. All others bloom during the day.

Native to Brazil and commonly found north through Mexico.
A sprawling shrub growing 15 ft tall. Deciduous in cool winter climates. It is easily propagated from cuttings or seeds.
Grows in full sun or partial shade. It needs well-drained soil but more water than most cacti, especially during the summer growing season.
Pereskia is a genus in the cactus family that is unusual in having large leaves as well as spines. P. grandifolia has pink or white rose-like flowers which are followed by pear-shaped green fruit.
The Rose Cactus grows in the Cactus Garden, along with several other types of Pereskia.
An evergreen coniferous tree which can reach up to 100 feet tall. Younger trees have a distinctive conical shape, which becomes rounded with age as the lower branches are dropped. They make beautiful shade trees with enough space, though the large cones and fallen spiny dried branchlets make them hazardous in areas with pedestrians.
Grows in full sun to partial shade; needs regular watering. Young plants make good container specimens outdoors and also indoors, as they are able to grow well in low light.
Bunyas have two types of foliage. The younger or understory needles are narrow, glossy green with a point and are arranged in two rows. Mature leaves are stiff with very sharp points and spirally arranged around the branchlets. A. bidwillii produces very large, spiny female cones up to 2 feet long and 1 foot wide, weighing 10 - 15 pounds. The cones take two years to mature, and each contains up to a hundred seeds. The seeds were a food source for aboriginal Australian peoples.
There are five A. bidwillii at Lotusland growing in the Japanese Garden and the Blue Garden.
Iochroma coccinea and Iochroma cyaneum
There are around 20 species of Iochroma, native to Central and South America
The two species of Iochroma growing at Lotusland are shrubby perennials 8-10 feet tall. They can be trained as a small tree or pruned into a rounder shrub form. The flowering is on the new growth, so prune stems back at the end of the blooming season to promote next year’s flower production.
Plant in full sun to partial shade. Iochroma are not drought-tolerant and require regular watering during the summer months.
Iochroma have 3 inch long tubular flowers that hang down from the branches. They flower from spring through fall, or sometimes all year round in warm-winter areas.
There are both red-flowered (Iochroma coccinea) and blue-flowered (Iochroma cyaneum) species growing in the Fern Garden.
