#red flowers

• Aesculus pavia — Scientific name of the red buckeye, a small deciduous tree or shrub species native to the southeastern United States, structurally recognized by its erect inflorescences with bright red tubular flowers and smooth, spineless capsules containing seeds rich in toxic saponins. It is widely cultivated as an ornamental plant in parks and gardens due to the vibrant color of its spring blooms and its ability to attract hummingbirds.
• Agapetes buxifolia — A shrub species in the genus Agapetes, native to the mountainous regions of Northeast India (Assam) and Bhutan, characterized by small, oval, evergreen leaves that structurally resemble those of boxwood (Buxus), and bright red tubular flowers, often solitary or grouped in small fascicles. Structurally, the plant develops a swollen lignotuber at the base for water storage and is grown in greenhouses as a spectacular botanical rarity.
• Red kangaroo paw — A herbaceous perennial species of the Anigozanthos genus, remarkable for the deep red, purple, or maroon color of its tubular flowers. This structural plant develops vigorous, branched flowering stalks completely covered in fine red hairs, creating a deep velvety appearance, and is widely cultivated in Mediterranean climate regions or warm greenhouses due to its high ornamental value.
• Aporocactus martianus — A rare species of epiphytic or lithophytic cactus native to Mexico (endemic to Oaxaca state), belonging to the genus Aporocactus (classified by some taxonomists as Disocactus martianus). It is distinguished by thick, deeply ribbed green trailing or pendulous stems (bearing 8-10 pronounced ribs), reddish-brown acicular spines, and large, tubular, bright scarlet-red flowers that remain open both day and night.
• Aylostera deminuta — A species of perennial dwarf cactus native to the arid rocky regions of Argentina and Bolivia, structurally recognized by its dark green cylindrical-globose stems covered with rigid brown or whitish spines. Its specific epithet emphasizes the reduced dimensions of the plant body, which compensates however with huge funnel-shaped, bright red or intense orange flowers arising delicately from the lower areoles, creating a striking visual contrast.
• Aylostera pseudodeminuta — A perennial species of dwarf cactus native to the mountainous and arid areas of Argentina, structurally classified as a close link within the Rebutia complex. The plant develops spherical or short cylindrical vibrant green stems covered with dense, brown or yellowish spines. Its specific name emphasizes the great morphological similarity to the deminuta species, from which it is delicately differentiated however by significantly larger funnel-shaped, brilliant bright red flowers that erupt abundantly from the lower areoles.
• Aylostera spinosissima — A perennial species of dwarf cactus native to the mountainous and arid regions of Bolivia, structurally recognized by its dark green globose or short cylindrical stems, characterized by an amazing density of long, thin, and extremely rigid spines. Its specific epithet originates from Latin, meaning 'most thorny', reflecting this dense protective shield from which spectacular, deep brick-red funnel-shaped flowers erupt delicately in spring from the lower areoles.
