Sunflower
Helianthus annuus
The Sunflower is an annual plant in the Asteraceae family, known for its large yellow flowers that follow the sun's movement (heliotropism). Native to the Americas, it is cultivated worldwide for both ornamental purposes and the production of seeds and oil.
Beach Sunflower
Helianthus debilis
Helianthus debilis, commonly known as beach sunflower, is a sprawling, short-lived perennial native to coastal regions of the southeastern United States. This vigorous groundcover produces a dense carpet of bright yellow flowers, blooming almost year-round in warm climates. Individual flowers measure 2-3 inches across with sunny yellow rays surrounding a dark reddish-brown central disk. The distinctive triangular, slightly lobed leaves resemble cucumber foliage, which is the origin of its alternate common name, cucumberleaf sunflower. This species is exceptionally salt-tolerant, drought-resistant, and well-adapted to harsh coastal environments, making it an excellent choice for beach gardens, dunes, and low-maintenance landscapes. The plant grows rapidly, self-seeds prolifically, and spreads via underground runners. It attracts butterflies and songbirds, making it valuable for pollinator gardens.
Maximilian sunflower
Helianthus maximiliani
Maximilian sunflower (Helianthus maximiliani) is a perennial sunflower in the Asteraceae family, native to the prairies of central North America from Canada to northern Mexico. It is named after Prince Maximilian of Wied-Neuwied, who came across it on his travels. It forms clumps of upright, hairy stems 1 to 3 m tall with narrow leaves up to 30 cm long, grayish from fine white hairs and folded upward. From late summer into early fall the stems fill with yellow flower heads 5 to 7 cm across, with 15 to 40 rays and a faint chocolate scent. It spreads by rhizomes and seed into large colonies, draws bees and butterflies, and its seeds feed birds.
Prairie Sunflower
Helianthus petiolaris
Helianthus petiolaris, commonly known as the Prairie Sunflower or Lesser Sunflower, is a fast-growing annual native to the dry prairies and sandy soils of western and central North America. It produces cheerful bright yellow daisy-like flowers with dark brown central discs from summer through fall, attracting bees, butterflies, and other pollinators.

One of the most productive and hardy food crops, it thrives in a wide range of conditions and was a staple food of Native American peoples long before European contact.
Helichrysum
Helichrysum
Helichrysum is a large genus of about 600 species in the daisy family (Asteraceae), native mainly to Africa and Madagascar, with others around the Mediterranean, in Eurasia and Australasia. Most are low, bushy subshrubs or perennials with narrow, often silvery or woolly grey leaves and clusters of small button-like flower heads surrounded by dry, papery bracts that keep their shape and colour when dried, hence the names everlasting, immortelle and strawflower. In gardens the most common are Helichrysum italicum (curry plant), with curry-scented silver foliage and mustard-yellow flowers, Helichrysum petiolare (licorice plant), grown for its trailing felted leaves, and compact rock-garden species such as H. amorginum and H. stoechas. Grown plants usually stay 20-60 cm tall. The big, colourful annual sold as strawflower (formerly H. bracteatum) is now classified as Xerochrysum bracteatum.
Curry Plant
Helichrysum italicum
Helichrysum italicum, commonly known as the Curry Plant, is a drought-tolerant, aromatic evergreen subshrub native to the Mediterranean region.
