Night-blooming cereus is the common name referring to many flowering ceroid cacti that bloom at night. The flowers are short lived, and some of these species, such as Selenicereus grandiflorus , bloom only once a year, for a single night, [ 1 ] though most put out multiple flowers over several weeks, each of which opens for only a single night.
Coreopsis (/ ˌ k ɒr iː ˈ ɒ p s ɪ s / [2]) is a genus of flowering plants in the family Asteraceae. Common names include calliopsis and tickseed , a name shared with various other plants . Description
Plants produce both basal and cauline leaves; the foliage occupy 1/4–1/2 of the plant height, the leaves have petioles 1–6(–10+) cm long, with simple leaf blades or they sometimes have 1 or 2, or more lateral lobes. The basal leaf blades are suborbiculate or ovate-elliptic to lance-ovate and typically 15–55 mm long and 9–25 mm wide.
The flower heads contain ray florets up to 2.5 centimeters long, or sometimes longer. [6] They are yellow, and generally a paler shade of yellow than related native Coreopsis. [4] The center of the head has many disc florets that bloom yellow and darken as they dry. [6] The plants flower in summer [6] and the herbage may age red in the fall. [5]
Coreopsideae is a tribe of flowering plants belonging to the Asteroideae subfamily. [1] It includes widely cultivated genera such as Coreopsis, after which the tribe is named, as well as Cosmos and Dahlia.
The stem of Coreopsis gigantea is a trunk up to 1 metre (3 + 1 ⁄ 2 feet) tall, and 4–10 centimetres (1 + 1 ⁄ 2 –4 inches) in diameter. The plant can reach 3 m (10 ft) high by 0.61 m (2 ft) wide. [6] [7] It is summer deciduous, leaving a sculptural bare trunk and branches during the dry season.
Coreopsis hamiltonii typically grows 10–20 centimetres (3.9–7.9 in) tall or sometimes taller when in bloom. The foliage is low growing, producing bright golden yellow colored flower heads and red purplish tinted peduncles. The foliage is deeply cut with a thin ferny shape.
The plant has foliage that is lobed and mostly linear in shape, with lobes that are 5–30 mm long and 1–2 mm wide. The 12–20 mm long flower phyllaries number 12–13, sometimes more, and they are lanceolate. [6] Plants bloom in late winter to early summer, with normally one or two flower heads per stem, on 15 to 30 cm long peduncles, but ...
