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 ...
The leaves are scale-like, 2–5 mm long, and produced on rounded (not flattened) shoots; seedlings up to a year old have needle-like leaves 4–8 mm long. The seed cones are globose to oblong, 20–40 mm long, with 6–14 scales, green at first, maturing brown about 20–24 months after pollination.
Rumex obtusifolius is a perennial herbaceous flowering plant that grows to a height of 40 to 150 cm (16 to 59 in). [2] It is easily recognizable by its very large oval leaves with cordate bases and rounded tips, some of the lower leaves having red stems. [2]
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 ...
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.
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 ...
Escape – a plant originally under cultivation that has become wild, a garden plant growing in natural areas. Evergreen – remaining green in the winter or during the normal dormancy period for other plants. Eupotamous – living in rivers and streams. Euryhaline – normally living in salt water but tolerant of variable salinity.
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.
