A large, evergreen tree, Cupressus × leylandii reaches a size between 20 and 25 m high, with its leaves giving it a compact, thick and regular habit. It grows very fast with yearly increases of 1 m. The leaves, about 1 mm long and close to the twig, are presented in flaky, slightly aromatic branches. They are dark green, somewhat paler on the ...
One study shows that growing chili peppers near tomatoes in greenhouses increases tomato whitefly on the tomatoes. [57] Cucumbers and squash can be used as living mulch, or green mulch, around tomato plants. The large leaves of these vining plants can help with soil moisture retention. [79] Turnips and rutabagas: Brassica rapa and Brassica ...
A geophyte (earth+plant) is a plant with an underground storage organ including true bulbs, corms, tubers, tuberous roots, enlarged hypocotyls, and rhizomes. Most plants with underground stems are geophytes but not all plants that are geophytes have underground stems. Geophytes are often physiologically active even when they lack leaves.
Cryptomeria grows in forests on deep, well-drained soils subject to warm, moist conditions, and it is fast-growing under these conditions. It is intolerant of poor soils and cold, drier climates. [9] It is used as a food plant by the larvae of some moths of the genus Endoclita including E. auratus, E. punctimargo and E. undulifer.
Cypress are evergreen trees or large shrubs, growing to 5–40 m (16–131 ft) tall, exceptionally up to 102 m tall (the second-tallest tree species on earth, after Sequoia sempervirens) in Cupressus austrotibetica. [5] The leaves are scale-like, 2–6 mm long, arranged in opposite decussate pairs, and persist for three to five years. On young ...
Leaf expansion is a process by which plants make efficient use of the space around them by causing their leaves to enlarge, or wither. This process enables a plant to maximize its own biomass, whether it be due to increased surface area; which enables more sunlight to be absorbed by chloroplasts, driving the rate of photosynthesis upward, or it enables more stomata to be created on the leaf ...
Phyllanthus niruri is a widespread tropical plant commonly found in coastal areas, known by the common names gale of the wind, stonebreaker, shatter stone, seed-under-leaf, quebra pedra and chance pierre. It is in the genus Phyllanthus of the family Phyllanthaceae.
Some of the species, like the majority of Bromeliaceae, grow as funnel bromeliads, with a compressed stem axis. The leaves are then close together in rosettes, and cover the lower areas of the leaves, forming a funnel for collecting water. [2] These leaf rosettes, a common physical characteristic in Tillandsia species, collect nutrients and water.
