Plants suitable for growing in humid environments, e.g. Typha and Pyracantha coccinea

Typha is a small genus with only about a dozen species, distributed in almost all regions of the world except South Africa, but most species grow in the northern hemisphere. They like to stay at a wetland evirment. Typha is perennial aquatic or marsh herb. The rhizome is milky white. The above-ground stems are strong, tapering upwards, 1.3-2 meters high。

Typha belongs to Typhales, Typhaceae Juss, Typha Linn.

How Typha could live in wetland during any weather?
Typha like a hot and humid climate. The suitable temperature for growth is 15-30℃. When the temperature drops below 10℃, the growth basically stops. During the winter, it can withstand a low temperature of minus 9℃. When the temperature rises above 35℃, the plant grows slowly. The most suitable water depth is 20-60 cm, and it can withstand 70-80 cm deep water. This growth habit gives cattails strong vitality to fight any extreme weather.

My observation is about plants and insects that are suitable for growing in the humid weather in Vancouver. Except for cattails, most of my materials are not suitable for cold. It may be because Vancouver is in a humid and warm environment and winter is not very cold, so Some plants will grow here that are not available in other locations.

Flora and Fauna (Sunflower) Journal Entry

The Helianthus Annuus, also known as the common sunflower, is situated in the Helianthus genus, which is in the Asteraceae Family, Asterales Order, and Magnoliopsida class. Which is a section in the magnoliophyta division, also known as the flowering plant, which falls under all the seed plants, known as the spermatophyta superdivision, under the subkingdom, tracheobionta, called vascular plants, as well as the plantae kingdom, which encompasses all plants; plants are a part of the Eukaryotes Domain, which falls under Archaea and Eukaryotes, and falls in all of life.

Since there is a wide variety of species from the different locations, it is difficult for all the species to have a common adaptation. Since the species thrive in different environments, eukaryotes have adapted to their environment in different locations around the world, for example, species in British Columbia have adapted to the wet environment, however species in California have adapted to the burnt environment, by triggering the release of seeds during wildfires.

One adaptation of the common sunflower, Helianthus Annuus, is that since young sunflowers require complete exposure to the sun during growth, they have adapted to turn towards the sun the entire day, east in the morning, and west in the afternoon.

The Adaptations and Phylogeny Placement of Candelabra Aloe Compared to Other Species

Phylogeny placement of Candelabra Aloe

Candelabra aloe, also called Mountain Bush Aloe is in the species of aloe that falls within the family of aloes, which are part of monocotyledons, which are a branch of flowering plants. Flowering plants are a branch of seed plants, which are part of vascular plants, which then fall in the wider group of land plants that are part of green plants. Green plants are part of the wider plant classification, which are part of plants, alveolates, brown algae, and more, which are part of Eukaryotes. Eukaryotes fall under archea and eukaryotes, which then falls under all life.

Adaptations of Other Species

As of now, there are a great variety of adaptations in our group project, especially because we have chosen a wider topic due to the distances between us, and each specific species observed has different adaptations to best fit their environment. For example, while plants like the Ghostplant, a type of succulent, and the Cadelabra aloe both are adapted to drought climates, others, like roses and the California poppy, have adapted to attract pollinators with their bright colors.

One unique adaptation of the Candelabra Aloe

One unique adaptation of my obervarions os the ability to retain water that was developed by the Candelabra aloe. The leaves are thick and fleshy to retain water during periods of drought, and also have small spikes around the edges of the leaves to ward off predators. Furthermore, the leaves grow in rosettes to maximize the amount of sunlight it gets, which allows for photosynthesis. Lastly, the Candelabra can grow to great heights, though the average height is about 3 meters, further aiding in its ability to get sunlight.
