Quadricolor Agave Lopthana

The Quadricolor Agave Lopthana, also known as the “painted agave”, is a stunning and unique succulent that can add a pop of color to any indoor plant collection. This plant is native to the mountains of Mexico and boasts vibrant green and yellow striped leaves.

Caring for it is relatively easy, but there are a few key things to keep in mind to ensure it thrives. It is drought-tolerant and does not need frequent watering. Water it deeply, but allow the soil to dry out completely between watering. Overwatering can lead to root rot, so be sure to check the soil moisture before watering.

The Quadricolor Agave Lopthana thrives in hot, dry climates with alkaline soils that are well-drained and low in nutrients. It prefers soils with a pH between 7.5 to 8.5, which are moderately alkaline. It does not require rich, fertile soil with high organic matter or nitrogen. In fact, too much fertilizer can reduce flowering. Poor, infertile soil is ideal.

This plant prefers bright, direct light. Full sun exposure is essential. It needs 8-10 hours of direct, unfiltered sunlight per day. Shady conditions will cause the plant to become leggy, spindly and lose its natural rosette form.

The Quadricolor Agave Lopthana can be propagated from offsets and seeds. The easiest and most common way is to propagate offsets. Look for pups growing around the base of the parent plant. Carefully detach the pups with a sharp knife or saw, leaving some roots attached. Allow the wounds to dry for a day or two before planting.

Quaker’s Bonnet

The Quaker’s Bonnet, also known by its scientific name Primula vulgaris, is a primrose plant that can commonly be found presented at flower shows. This plant is native to several areas across Europe and Turkey.

It is a compact, rosette-forming, evergreen perennial with dark green textured foliage. Large, fragrant double rose-violet to lilac-pink frilly flowers appear from early winter through until early spring when flowering increases. The plant is characterized by white, bell-shaped, butterfly-like flowers with purplish veining in the center.

The Quaker’s Bonnet prefers full sun or partial shade and grows in moderately fertile, moist but well-drained, humus-rich soil. It can be propagated by division in autumn or after flowering.

Quaking Aspen

The Quaking Aspen (Populus tremuloides) is a tree in the willow family. It is the most widely distributed tree species in North America, growing from Alaska and Canada all the way south to Mexico. It can withstand a wide range of climatic conditions by growing at lower altitudes in the north and higher altitudes in the south.

The Quaking Aspen is easily identified by its smooth, light-colored bark, interrupted at intervals by darker knots and horizontal scars. An even better-identifying feature is its flattened leafstalks, which cause the leaves to “quake” when the wind blows. The leaves are rounded to slightly triangular, 3 inches across, and finely toothed.

This tree is not only known for its unique heart-shaped leaves but also for its stunning fall color (golden aspen), bark color (white aspen), or favorite habitat (mountain aspen). It grows about 2 feet a year and on average, it lives about 60 years and up to 150 years in the western United States.

Quaking Aspens can sprout new trees from one root underground. So, even if a tree dies after 60 years or so, a new shoot from the same root underground may produce another clone. So, the root may live underground for tens of thousands of years. Pando, a grove of quaking aspens in Utah, is surmised to be the oldest living organism on the planet.

This tree prefers full sun exposure and well-drained soil with a pH that can be acidic, neutral, or alkaline. It’s a high-maintenance plant due to its ability to spread unless it is a large stand of quaking aspen that you desire over time. To grow a single quaking aspen as a specimen plant or shade tree, you must continually remove any new plants from the root system to avoid growing unwanted trees and protect foundations and septic systems.

Quaking Grass

The Quaking Grass, scientifically known as Briza, is a group of easy-to-grow, dependable ornamental grasses. It’s native to various regions and can be found in different sizes and scales, suitable for nearly any garden in a temperate climate.

This grass is known for its tiny, pendulous flowers that dry out in the sun and shiver charmingly in a breeze. It’s often grown in 18-inch-high clumps and is perennial in USDA zones 4 to 10. Quaking grasses make an airy, ornamental backdrop to flowering perennials.

Quaking Grass grows best when used in masses and is excellent for cutting, fresh or dried arrangements. It grows in a dense clump about 2-3 ft. tall (60-90 cm) and 12-18 in. across (30-45 cm), enjoying full sun and average, medium moisture, well-drained soils.

From tufts of smooth, flat grey-green leaves, it bears branched heads of ‘quaking’ green-yellow flowers, often tinged purple. It’s a short-lived perennial and can take a while to become established. Best grown in groups for maximum impact, grow Briza media in moist but well-drained soil in full sun to partial shade.

In addition to its aesthetic appeal, Quaking Grass also has practical uses. Widely cultivated for use by florists and designers, their delicate seed heads add texture to floral arrangements. In a garden, Quaking Grass can fill holes between seasons—and if you leave the seed heads in place after other perennial flowers die back, Quaking Grass will feed birds in early winter.

 Queensland Firewheel Tree

The Queensland Firewheel Tree, scientifically known as Stenocarpus sinuatus, is a medium to large Australian rainforest tree. It’s part of the Proteaceae family and is widely planted as an ornamental tree in various parts of the world.

This tree is characterized by its irregular grey-brown bark, simple or pinnate wavy-edged, veined leaves that are 12-20 cm long. The leaves can be oval-shaped, lobed or have wavy edges. They are usually 15 – 25 cm long (but can be up to 45 cm long) and 2 – 5 cm wide.

The Queensland Firewheel Tree is known for its bright red pinwheel flowers which form mostly between February and March. These flowers cluster in a wheel-like arrangement at the end of a stalk. The cluster can be up to 10 cm in diameter and consists of 6 – 20 flowers.

Following the flowering period, a grey-brown seed pod which is 5 – 10 cm long and has short hairs appears. The seeds inside are 2.5 – 3.5 cm long.

This tree can grow up to 40 metres tall and 75 cm in trunk diameter in its natural habitat, but when grown in gardens it usually reaches a height of only about 10 m with a width of 5 m. It’s adaptable to a range of climates if given adequate water and is planted outside these regions.

The Queensland Firewheel Tree is not only beautiful but also practical. It’s a popular ornamental tree and the subject of some of Margaret Preston’s most popular prints.

 Queen Anthurium

The Queen Anthurium, also known as Anthurium Warocqueanum, is a tropical plant native to the rainforests of Central and South America. It’s a popular houseplant among enthusiasts and collectors due to its large, heart-shaped leaves and striking, velvety texture.

This plant is characterized by showy long and narrow dark green leaves with relatively short stems. The beautiful foliage of this plant is dark green with a leathery feel. The leaves are narrow and elongated and may appear to be hanging downwards. The silver-white venation on the leaves gives the plant a unique overall appearance. The variegations on the leaves will become even more prominent as your plant matures.

During the growing season, the Queen Anthurium produces inconspicuous blooms that show up on a spathe enclosed by a spadix of yellow-green color. The spadix houses red-colored berries. These berries captivate birds to take forward the process of pollination.

This exquisite plant can grow to a magnificent size and make the rest of your indoor plant collection look small in comparison. When grown in its natural tropical habitat it can show a tremendous growth rate along with enormous size. However, when grown indoors its size is restricted by limiting environmental factors. On average, the plant can grow up to 6 feet tall while the leaves can grow 3 to 4 feet long.

Most species of the genus Anthurium are considered toxic, and Queen Anthurium is no exception. Due to its toxicity, the plant is not safe for pets and humans alike.

Queen Victoria Agave

The Queen Victoria Agave, scientifically known as Agave victoriae-reginae, is a small species of succulent flowering perennial plant. It’s native to the Chihuahuan Desert in the Mexican States of Coahuila, Durango, and Nuevo León.

This plant is highly variable in form, but in general, the rosettes are small and compact, growing to 0.5m. It’s composed of short, rigid, thick leaves that are green with a pattern of distinctive white markings. The markings are generally along leaf keels or margins, giving a sort of polyhedral appearance. Marginal teeth are usually lacking, while the terminus of the leaf may include 1 to 3 spines, each 1.5–3 cm in length.

The Queen Victoria Agave is noted for its streaks of white on sculptured geometrical leaves and is popular as an ornamental plant. Cream-colored flowers are borne in erect racemes up to 4m in length. A. victoriae-reginae is found with about a half-dozen subspecies named.

This plant is not only beautiful but also practical. It’s a stunning, drought-tolerant plant with large leaves. It’s cold-hardy as agaves go and thus finds favor as a small accent in many northerly gardens. However, it is recommended in the UK that this plant be kept in heated conditions under glass during winter.

Quehla Chin Cactus

The Quehla Chin Cactus, scientifically known as Gymnocalycium quehlianum, is a species of flowering plant in the family Cactaceae. It’s native to northern Argentina.

This cactus is slow-growing with spherical stems that have 8 to 14 low, variously tuberculate ribs lined with closely placed, felted areoles bearing clusters of weak spines. The stems can grow solitary or sparingly clustering and reach up to 6 inches (15 cm) in diameter, usually much smaller. They range in color from brown to dark grayish-green.

Each areole bears 5 to 7 radial spines that are pale yellow, brownish at the base, and up to 0.4 inches (1 cm) long. The flowers are funnel-shaped, white, flushed red at the base of the petals and in the throat, and appear at the top of the stems in summer. The fruits are club-shaped, greyish-brown, and contain brownish-black seeds.

This cactus grows in rocky outcrops in the Sierras de Córdoba at elevations that range from 1,970 to 3,940 feet (600 to 1,200 m). It requires light shading from the sun during the hottest months. Too much shade can cause loss of flowers.

The Quehla Chin Cactus prefers soil with good drainage. It can tolerate high temperatures but is not cold-hardy. It grows best in USDA Plant Hardiness Zones 9b to 11b, with average minimum winter temperatures ranging from 25 to 50 °F (-3.9 to 10 °C).

Water your Gymnocalycium quehlianum frequently during the growing season, but allow the soil to dry out completely before watering again. Cut back on watering during winter when it goes dormant. While it does not need much fertilizing, occasionally giving the plant extra nutrients will keep it healthy and prolong the time for repotting.

It is recommended to repot this cactus every two years into a pot that is the same size or slightly larger. Late winter or early spring is the best time for repotting.
