Foliage during autumn Dogwood trees in Nagano, Japan. Cornus florida is easily propagated by seeds, which are sown in the fall into prepared rows of sawdust or sand, and emerge in the spring. Germination rates for good clean seed should be near 100% if seed dormancy is first overcome by cold stratification treatments for 90 to 120 days at 4 °C ...
The pattern may be unstable, plus the plants can produce green growth reversions. It benefits from siting in some shade. 'Wolf Eyes' [15] Variegated form with leaves that show a uniform white margin. The leaf margins are often prominently wavy. In fall, the leaves develop attractive pink to red coloration. Shrubby and slow-growing, to 10' tall ...
Small trees such as holly and dogwood are understory specialists. In temperate deciduous forests, many understory plants start into growth earlier in the year than the canopy trees, to make use of the greater availability of light at that particular time of year. A gap in the canopy caused by the death of a tree stimulates the potential ...
For example, with an annual growth rate of 4.8% the doubling time is 14.78 years, and a doubling time of 10 years corresponds to a growth rate between 7% and 7.5% (actually about 7.18%). When applied to the constant growth in consumption of a resource, the total amount consumed in one doubling period equals the total amount consumed in all ...
Cornus canadensis is a slow-growing herbaceous perennial growing 10–20 centimetres (4–8 inches) tall, generally forming a carpet-like mat. The above-ground shoots rise from slender creeping rhizomes that are placed 2.5–7.5 cm (1–3 in) deep in the soil, and form clonal colonies under trees. The vertically produced above-ground stems are ...

RGR is a concept relevant in cases where the increase in a state variable over time is proportional to the value of that state variable at the beginning of a time period. In terms of differential equations, if is the current size, and its growth rate, then relative growth rate is. . If the RGR is constant, i.e., , a solution to this equation is.
Limited growth of the penis occurs between birth and 5 years of age, but very little occurs between 5 years and the onset of puberty. [1] [6] [needs update] The average size at the beginning of puberty is 6 cm (2.4 in), with adult size reached about 5 years later. W.A. Schonfeld published a penis growth curve in 1943.
