Sunflower (Helianthus):
USDA hardiness zones 2-11
Sunflowers (Helianthus) are renowned for their large and vibrant yellow flowers. They are known for their iconic appearance, featuring a central disk surrounded by numerous ray-like petals ranging in color from bright yellow to golden yellow.
The disk in the center of the flower is composed of tiny individual florets that develop into seeds once pollinated.
These yellow flowering herbs are famous for their impressive size, with some varieties growing as tall as 10-15 feet (3-4.5 meters) or even more.
The flowers themselves can reach diameters of 8-12 inches (20-30 centimeters) or larger, depending on the specific cultivar. The petals are long and often slightly pointed, giving the flower a distinctive appearance.
The flowering period of sunflowers occurs during the summer months, with the flowers facing toward the sun and tracking its movement throughout the day. This behavior is called heliotropism.
The vibrant yellow petals and the prominent disk of the sunflower attract bees, butterflies, and other pollinators, which play a vital role in the plant’s reproduction.
The seeds of sunflowers are highly nutritious and are a rich source of healthy fats, protein, fiber, and various vitamins and minerals. They are used as a snack or an ingredient in cooking and baking.

Yacon
USDA hardiness zones 7 to 11
Yacon (Smallanthus sonchifolius) is a perennial plant native to the Andean region of South America. It is primarily cultivated for its edible tubers, which have a sweet, crisp, and juicy texture.
It belongs to the Asteraceae family and is related to sunflowers and daisies. The plant’s growing zone and requirements can vary depending on the climate and specific cultivar.
Yacon is grown in regions with cool temperate to subtropical climates. It thrives in USDA hardiness zones 7 to 11.
This yellow flowered herb prefers mild temperatures between 60°F (15°C) and 75°F (24°C) but can tolerate a range of temperatures from 45°F (7°C) to 80°F (27°C). In areas with hotter summers, partial shade or protection from intense sunlight can help prevent heat stress.
Regarding soil conditions, yacon prefers loose, well-draining soils with a pH between 5.5 and 7.5. The soil should be rich in organic matter and have good water-holding capacity. Yacon can tolerate various soil types, including sandy, loamy, and clay. However, heavy clay soils should be amended to improve drainage.
Yacon is propagated by planting its tubers or rhizomes. It is usually planted in spring after the last frost date or during the cooler months when soil temperatures reach around 60°F (15°C).
The tubers should be planted horizontally, with the buds facing upwards, at a depth of about 6 to 8 inches (15 to 20 cm). Space the plants about 24 to 36 inches (61 to 91 cm) apart to allow sufficient room for growth.
Regular watering is crucial for yacón plants, especially during the active growing season. They have high water requirements and prefer consistently moist soil. Avoid waterlogging or overly saturated soil, as it can lead to root rot. Applying mulch around the plants can help retain soil moisture and suppress weed growth.
Yacon plants can grow quite tall, reaching heights of 4 to 8 feet (1.2 to 2.4 meters). As they grow, they develop attractive leaves and produce small, sunflower-like yellow flowers.
It’s advisable to stake or support the plants to prevent them from toppling over under their weight. Some varieties may require pruning to maintain a more manageable size and shape.
Harvesting yacón tubers occurs in late autumn or early winter when the plants have completed their growth cycle. The tubers are ready for harvest when the leaves turn yellow and die back.
Carefully dig around the plants to avoid damaging the tubers, then remove and store them in a cool, dry place. Yacón tubers can be stored for several months and develop a sweeter flavor over time.
Yacón tubers are valued for their crisp texture and sweet taste. They can be consumed raw, sliced into salads, or used as a low-calorie substitute for sugar in various culinary preparations.
Toothache Plant/Paracress
USDA hardiness zones 9 to 11
Toothache Plant (Acmella oleracea or Paracress) is a flowering herbaceous plant native to Brazil and other parts of South America. It is popularly known for its unique properties, particularly its numbing effect on the mouth, which is why it earned the name “Toothache Plant” or “Paracress.”
It is a small annual or short-lived perennial plant belonging to the Asteraceae family, commonly called the daisy family. It grows well in tropical and subtropical regions but can also be cultivated as an annual in temperate climates. It is commonly grown as a medicinal and culinary herb.
This herb with yellow flowers is best suited for USDA hardiness zones 9 to 11. It prefers warm temperatures and thrives in full sun to partial shade. The plant can tolerate a range of soil types, but well-draining, fertile soil is ideal for its growth.
The flowers have yellow or orange petals and a central disc that may be dark red or purplish. They are produced in clusters and add a vibrant touch to the plant.
Toothache Plant contains a compound called spilanthol, which is responsible for the numbing sensation it produces when consumed. This effect is often utilized to alleviate toothaches, hence the common name.
The leaves and flower buds of the plant are used in various culinary preparations, such as salads, soups, and stir-fries, to add a tingling and numbing sensation to dishes.
When growing Toothache Plant, starting from seeds or young seedlings is recommended. The seeds should be sown in well-prepared soil after the last frost date. They should be lightly covered with soil and kept moist until germination, which typically takes around 7 to 14 days. Space the plants about 6 to 12 inches (15 to 30 cm) apart to allow room for growth.
Toothache Plant requires regular watering to keep the soil consistently moist, but it should not be waterlogged. Mulching around the plants can help retain moisture and suppress weed growth. The plant has a relatively fast growth rate and can reach a height of 12 to 24 inches (30 to 60 cm).
The leaves and flower buds can be harvested once the plant has reached a suitable size and the flowers have fully developed. Harvest before the plant starts to produce seeds for the best flavor and quality.

Tansy has been used for centuries for both medicinal and culinary purposes. However, it contains certain compounds, such as thujone, which can be toxic in large quantities. Therefore, using Tansy with caution and under professional guidance is recommended.
Tansy can be grown from seeds or propagated through division in the garden. Sow the seeds directly in the garden or indoors in spring or early summer before transplanting.
The seeds should be lightly covered with soil and kept consistently moist until germination, which typically takes around 10 to 14 days. Space the plants about 12 to 18 inches (30 to 45 centimeters) apart to allow for their spreading growth habit.
Tansy is a relatively low-maintenance plant. It requires regular watering, especially during dry spells, but be careful not to overwater as it can lead to root rot. Once established, Tansy is quite resilient and can tolerate periods of drought. Deadheading the spent flowers can help promote continuous blooming and prevent self-seeding.
It’s worth noting that Tansy has a reputation for being a natural insect repellent, particularly against ants and flies. However, it can also repel beneficial insects, so carefully consider its garden placement.
