Introduction:
Digitalis purpurea, commonly known as the foxglove is one of the deadliest but at the same time most medicinal plants in our world. This flowering plant is very widespread being found in much of temperate Europe and parts of North America. While, the leaves, flowers, and seeds are all poisonous to us and other animals, compounds have been extracted from the species and are used in heart medicines and other medicinal products that we still use today. The foxglove can grow in very little soil and can often be found in many cracks and crevices making it a very common and recognizable plant species (Royal Botanic Gardens, 2011).
Description:
Digitalis purpurea is a biennial plant meaning that it only lives for two years and after that it dies, and reproduces (Cornell, 2014). It has soft, pubescent, ovate to lanceolate shaped leaves forming a basal rosette. During the first year of growth the plant forms a basal-rosette and does not mature until the next years grow cycle (Cornell, 2014). During the second year of growth the foxglove begins to grow a flowering stem that can reach 3-6 feet high (Cornell, 2014). The flowers form a spike growing off of the stem and can bear up to 20 flowers on each stem. Each flower is about 2” and bilaterally symmetric coming in a wide variety of colors such as; purple, lavender, pink, yellow, and white (Brun, 2014). Each flower has five petals that are fused into a coronal tube. The flowers hang down in a droop-like fashion and only come off of one side of the stalk, and last about four weeks. The foxglove is extremely poisonous and is lethal if ingested; all parts of the plant are toxic including; roots, stems, flowers, leaves, and so on. While, every part of this plant is toxic it i...

They can detect perceived threats, then convey warning signals to other plants via chemical signaling. Forewarned plants will then assemble their defenses against these potential threats, thus, increasing their chance of survival and reproduction. Communication and competition are common occurrences among the plant world. Another brilliantly, almost inconceivable capability plants possess is the ability to recognize coexisting family members within their home range....   [tags: Environment, Plant Species, Plant Communication]

Essay on The Effect Of Plant Outdoor On The Plants

- Many problems arose when conducting this experiment. Initially, I planned to record results every day for the plants, however, the plants did not always grow every day. The plant which received the most light in particular did not show many results initially as it took it up to nine days before recording results was possible. This was a set back and I ended up having to change the times at which I was recording results. I ended up measuring a day apart and then waited 3-4 days before recording results again....   [tags: Light, Photosynthesis, Plant, Fern]

Essay about pH Soil and Plant Growth

- The acidity or alkalinity level is dictated by the pH, potential of hydrogen, scale. Soil pH or soil reaction is an implication of the acidity or alkalinity of soil and is measured in pH units. Soil pH is characterized as the negative logarithm of the hydrogen particle fixation. As the measure of hydrogen particles in the soil builds the soil pH diminishes along these lines getting to be more acidic. From pH 7 to 0 the soil is progressively more acidic and from pH 7 to 14 the soil is progressively more alkaline or basic....   [tags: plant development, alkalinity of soil]

Reciprocal Coevolution and Plant-Pollinator Interactions Essay

- ... Due to certain restrictions, only specific species can act as a vector and that led to specialization of a relationship. It was more of a key and lock mechanism rather than a coincidental coevolution. Since the species that could not get to the specific flower, carried on until it found a suitable one. This therefore does not necessarily mean that either the flower or the vector altered their morphology just to increase the fitness. All of the above arguments are also thought to be the root of the mentioned ‘plant syndrome’ that specifies the pollinator response and the species that acts as a vector....   [tags: floral mechanisms, biology, plant syndrome]
