This is the second part of the series on the top air-purifying ornamental plants as declared by the National Aeronautics and Space Administration. If you have not yet seen the top 10, you may see them here. I am including pictures on each plant for the reason that most of the articles I see on the web do not have a picture for each of these important plants. This article may be the only one you can find on the web that has complete pictures. Some of the pictures may be those of plants I have in my own garden, while the rest are taken from other sites but of course, given proper photo credits. I am doing this really for my benefit as I want to have all 20 of these plants.
So here are the top 11 to 20 air-purifying plants.

11. Boston fern (Nephrolepis exaltata)

This is one outstanding filler plant which can give good coverage to any space that needs some lush sprucing up. Imagine this nook without this abundantly-growing Boston fern. It is easy to grow, easy to divide and gives you enough foliage for your flower arrangements.
12. Dwarf date palm (Phoenix robelenii)

This is one elegant palm I’ve been dying to have in my garden but which seems out of my budget right now. It makes a grand statement when set in a corner or in a frontyard. Apparently, it also serves to filter air.
13. Areca palm (Chrysalidocarpus lutescens)

I am presently growing a collection of this palm as it is so easy to grow and there seems to be a lot of seedlings growing in our yard, probably from bird droppings. My garden is attracting birds and butterflies lately and I’ve been blessed with some palm seeds growing here and there. Would you like some?
14. Kimberly Queen Fern (Nephrolepis obliterata)

16. Flamingo Lily (Anthurim andraeanum)

I have this air-cleaning plant but it it isn’t flowering yet. The leaves as well as the flower are heart-shaped. I find that it is rather difficult to grow but now that I have learned of it’s air-filtering powers, I would keep it.
17. Broadleaf lady palm (Rhapis excelsa)

You’ve probably seen this palm which has robust-looking leaves. I hope the birds in my garden would drop me down some seeds of this.
18. Cornstalk dracaena (Dracaena fragans)

This is one of the plants in my collection. It can grow as tall as a tree but can also be potted like this for a more streamlined look.
19. Gerbera daisy (Gerbera jamesonii)

Who would have thought these lovely ladies would be good cleaners too? Yes, they clean outdoor and indoor air well. If only I could find these in my city.
20. Weeping fig (Ficus benjamina)
