James C asked:


you know most flowers have common structures because their environment is relatively the same, but wat about flower in the desert and all the other extreme environments, how can they manage to survive.

ex: Sêth, in his desert, was angered against Osiris, for everywhere green things that Sêth hated were growing over the land–vine, and grain, and the flowers. Many times Sêth tried to destroy his brother Osiris, but always his plots were baffled by the watchful care of Isis.

Kate_ asked:


I have trellis installed behind my home that faces the south-east and gets the morning and mid-afternoon sun. I just got this as my very first home and I would like to plant some vines that could help cover these possibly all year round. I have never grown a plant in my life but this is going to be my big yearly project and I am quite determined.

I have been doing research on several vines. Snail vines (purple flowers), Passionflower, Morning Glory, and Kudzu vines are all very beautiful, and I was wondering if at all I could plant these type in this desert heat. I live in Lake Havasu City AZ, which gets to 120 degrees in the summer easily. We have a very dry climate as well…

http://www.wrcc.dri.edu/cgi-bin/cliMAIN.pl?azlhac

Please tell me if my efforts with any of these vines would be futile, and if so, what vine should I really try growing? My grandmother has snail vines at her home in this same town, but she’s had trouble without them getting proper shade… HELP?!?!?

This tree almost reminds me of a weeping willow except that it doesn’t weep. The branches seem light weight…any kind of wind will make it seem flowy. The tops are usually almost perfectly rounded. Like I said, its such a flowy and very pretty shady tree with no flowers or fruit ( I think ). Our climate here is close to arrid desert (west texas). Please help me…I want a tree like this to plant at home.

bb761866 asked:


Some species of bats feed on a sweet substance called nectar, which plants produce to attract pollinators. These bats are important pollinators of trees and other large plants in the tropics and the desert. They pick up pollen on their heads when they feed on flowers, and some of that pollen rubs off onto other flowers they visit. In fact, many plants in deserts and the tropics rely exclusively on bats to move pollen from one plant to another, ensuring fertilization.

I need help badly!

pcfwest asked:


my neighbor was moving and she gave me a bougainvillea that didn’t have that much leaves.
i have been watering it every day and new leafs have grown and i have been keeping it indoors and only taking it out a hour for sun
but i have been reading that they need a lot of sunshine(about 5 hrs) to bloom flowers .
but i live in arizona here it is a desert, it is very hot(like 110 ‘F)
and i worry that if i leave it outside 5 hours that it will die because of the excessive heat in arizona.

i am not a plant expert . so i will really appreciate all of the advice.

thank you
