No, pine trees are not flowering plants.
There are actually two types of seed bearing plants. There are gymnosperms, where the seeds develop on a surface, such as a pine cone. Gymnosperms do not flower. Then there are angiosperms, where the seeds develop within an ovary. Angiosperms are what we commonly call flowering plants.
Pine trees are gymnosperms, so they only produce cones and never flowers. The cones work as the male and female parts of the tree. The long tubular parts are the male cones, and they are covered in pollen. The larger brown pine cone that we are used to seeing have seeds under each little prong of the cone. They are the female cone.

These certain palm trees grow successfully in Seattle
1. Windmill Palm

3. Mediterranean palm (both green and blue varieties)
4. Needle Palm
5. Chilean Wine Palm
6. the Pindo or "Jelly" palm
Seattle is in growing zone 8 (Maximum winter lows between 10°F and 20°F). The last time Seattle saw a single-digit Fahrenheit temperature was 9°F in the winter of 1990-91. The all-time record low is 0° in downtown Seattle on January 31, 1950, and even then near the water it was still 4° warmer.
Marginal palms grown with success in Seattle:
- Blue Hespar Palm
- Sabal species - but it doesn't usually get warm long enough for their preferred 90°F high temperatures
- Mexican Fan Palm crossed with California Fan Palm - In cold winters keep copper fungicide handy.
- Canary Island Date Palm -shelter from NE winds, and use copper fungicide after periods below 17°F
- California Fan Palm - once per winter requires a liberal dose of copper fungicide, also repeated after any cold snap below 20° to prevent mold and crown rot.
- Mexican Fan Palm - best chance is near Puget Sound (Pacific Ocean saltwater) where the ocean moderates any cold temperatures - shelter from NE winds and cover emerging growth when below 20°F. *This palm can only survive 12°F if the center spear is wrapped and copper fungicide is added bi-weekly until the last frost in March.
The summer in Seattle is perfect palm weather, because May through September is the dry season, with summer highs between 67° and 85°F.
Typically only one to five days in the 90s, and the all-time high is 103°F.
However, Sabal Palms in particular do not prefer the cool, dry, semi-arid summers and do better in much warmer temperatures.

What is a shrub with glossy evergreen leaves and largefragrant white flowers?
Oleander is the name of one of many poisonous shrubs.
Specifically, oleander (Nerum oleander) can be a convenient choice for cultivators, gardeners, and landscapers. It grows in alkaline and poor soils. It has attractive parts and structure. It is drought- and salt-tolerant.
But all parts of an oleander shrub are poisonous. No amount of drying or processing changes that fact. Ingesting -- for example, chewing or saving foliage and twigs -- may dilate pupils, provoke diarrhea and nauseousness, and slow pulses. Additionally, burning any of the plant's parts will release toxic fumes.
If a tree falls and you didn't hear it did it fall?
the answer is no it does not make a sound, this is because sound does not exist until someone or something picks it up. nothing actually makes sound, if a tree falls it gives off "VIBRATIONS" and "ENERGY" and that vibration travels for so far, and if it does not reach an eardrum than that vibration never turned into a sound. Humans pick up these vibrations with there ear drums and we take it as a sound, but if an eardrum does not pick it up, its just a lost vibration.
this also applies to a microphone, think of the eardrum as a microphone.
so if a tree falls in the middle of no where and there is no one around to hear it, does it make a sound? no it makes a vibration and an energy.
