Q. I have a 4th floor apartment facing north. Any suggestions for plants on the porch which can survive winter in Las Vegas?
A. Below is a list of shade accepting plants that will take our cold winters. I listed all different size plants because you did not specify size requirements. A good source for info on particular plants is snwa.com under 'landscapes'.
Spider Agave (Agave bracteosa)
Soap Aloe (Aloe saponaria)
Guara-pink and white (Guara species)
Variegated Flax Lily
Yew Pine (Podocarpus microphylla or macrophylla)
Japanese Aralia (Fatsia japonica)
Gold dust Aucuba (Aucuba "Gold Dust')
Asparagus Fern (Asparagus spengerii)
Foxtail Fern ( Asparagus 'Foxtail')
Bay Laurel (Laurel nobilis)
Heavenly Bamoo (Nandina domestica)
Ivy (Hedera species)
Hope this helps. Feel free to contact me with other questions.
