Xanthoceras sorbifolium, also known as Shiny Leaf Yellowhorn, is an attractive large shrub or small tree, which is native to China. It generally reaches a height of 5-10 ft, but can develop into a small tree of 10-20 ft depending on the area. It is deciduous and is cold hardy at least to the 30s F for a short time, and can be grown in USDA Zones 4-7.

It thrives in full sun and semi-shade, requiring regular watering. In Spring, it bears multitudes of flower spikes densely packed with star-shaped white flowers featuring chartreuse centers that darken to an intense scarlet. These are heavily fragrant and very attractive to pollinators.

It also produces edible fruits, which hang from the branches in bunches at the end of summer. Each fruit has a single large seed covered by an orange/yellow skin. These seeds and skin are edible, but also have medicinal and therapeutic uses, making it a medicinal tree as well. The fruits have a sweet, tart flavor, and can be eaten raw or used in various recipes. The fruits are also high in protein, fiber, iron and vitamin B1, which has several health benefits. It can produce up to 10,000 fruits per season if it is in ideal conditions.

In colder regions, Xanthoceras sorbifolium is usually grown in a pot. While container grown plants require more attention and regular water and fertilizer, they are more easily managed in cold climates. The container should be sufficiently deep and wide to accommodate a root system. A rich potting mix, good drainage and exposure to full sun is recommended for the optimal growth of the plant.

Xerochrysum bracteatum, also known as Strawflower, is a popular plant choice for gardeners in USDA zones 8-10. This small plant is easy to care for and produces a showy display of colorful flowers that attract butterflies and hummingbirds. It can be grown in either full sun or semi-shade and requires regular or moderate watering to ensure optimal growth and flowering. The plant comes in a variety of colors, including pink, white, red, yellow, and orange.

When planting Xerochrysum bracteatum in a pot, gardeners in colder regions should take extra care to ensure the plant thrives. Bring the pot indoors during cold winters.

Xerochrysum bracteatum is not only a great addition to a garden but is also excellent for use in dried arrangements.

Xerochrysum bracteatum has been proven to be adaptable to cultivation and was first propagated and developed in Germany in the 1850s. Annual cultivars in a range of color forms, from white to bronze to purple flowers, are widely available.

Yucca typically grows up to 5-10 feet tall, that is a popular ornamental plant for Mediterranean gardens, giving a huge impact to the garden when in full bloom. Yucca boasts of attractive foliage, producing sword-shaped leaves that keep the plant looking green, even during the summer months. The uniqueness of the foliage and its variable forms makes it an excellent species for adding texture in the garden.

The ornamental foliage of the Yucca will delightfully burst into bloom during summer. The plant produces creamy white or off-white flowers that attract butterflies and hummingbirds. The fragrant blooms are also perfect for adding a touch of texture and interest to bouquets.

Different species of Yucca can tolerate cold within the USDA Zones 4a to 11, depending on the variety and growing conditions. The Yucca is also adapted to seaside conditions and is quite salt-tolerant, making it an ideal choice for coastal gardens.

Yucca requires minimal effort. The plant prefers well-drained soil, but it can tolerate a range of soil pH, both acidic and alkaline. It can also tolerate moderate levels of humidity and needs full sun to partial shade. Yucca is very tolerant of drought, so it needs only occasional watering during dry spells.

For gardeners living in cold regions, Yucca is an excellent choice for a pot-grown plant. It is important to provide adequate drainage and choose a pot that is large enough for the root system. During the growing season, make sure to water the Yucca regularly and feed it with a balanced fertilizer once a month. In winter, the plant will need some protection to survive the cold temperatures and the plant should be brought indoors.

Zamioculcas zamiifolia (Aroid Palm) is a small shrub reaching 2-5 ft tall, native to Tanzania, Zanzibar and other parts of eastern Africa. With its ornamental foliage and shiny elliptical leaves arranged in upright clusters, this resilient plant is remarkably easy to grow. It tolerates low water and low light conditions, thriving equally well in semi-shade. An excellent choice for a houseplant, it can also perform well in seaside gardens and other warm-climate outdoor settings in USDA Zones 9 11.

Zamioculcas is highly tolerant of salt, making it suitable for outdoor planters in coastal areas. It is also known for withstanding occasional neglect, including infrequent repotting. Water sparingly, as overwatering may cause lower leaves to yellow. When grown in containers, place in bright indirect light or partial shade; plants in full sun will need more frequent watering. In regions with winter frost, move pots indoors to a warm location and monitor for leaf discoloration. Fertilize lightly once or twice a year before growth starts in spring. With its glossy foliage, striking form, and ease of care, Zamioculcas zamiifolia is a standout specimen for both home and office.

Zamioculcas 'Black Dragon' is a rare and highly sought-after variety with foliage so dark it appears almost black. Young leaves emerge bright green and gradually deepen to their distinctive near-black shade as they mature. This dramatic color change, combined with the plant s naturally glossy texture, makes 'Black Dragon' a striking focal point in any collection. Its care requirements match those of the standard form, making it just as undemanding while offering an even bolder visual impact.
