Separate names with a comma.
The lichens aren't the problem. Possibly doing something to improve drainage....maybe a dry well near the plant?
There's severe limits to what's possible with genetic engineering. For example, monocot "trees" are organized entirely differently from plants...
Timber Press has a useful new, short book on "how plants work." Plant strategies for dealing with water shortage (and relatively short periods of...
I think that's harmless lichens. They show up pretty readily--I've got some on the delivery box for newspapers, not to mention branches on young...
Day lilies seem to get complicated--they've been cultivated in China for a long time and of course they spread vegetatively, so it's easy to...
They are quite different. The seed pods of Nelumbo are distinctive (easy to find photos) and are popular for dried flower arrangements....
In Florida, most of the Justicia brandegeana are fairly small, but there's also tall (2 meters at least) plants like the bright red "shrimp cocktail".
Many amaryllises go dormant before flowering, some don't, and they make reasonably good ornamental foliage in our climate, where they grow happily...
I have no experience with indoor mangos and my "condo mangos" (Mallika and Lancetilla) are growing larger than I would like. Fairchild Tropical...
I think you got it. A quick Google search didn't turn up much on B. guatemalensis, but here's a beautiful page on Beacarneas in Mexico. Those...
I concur with Junglekeeper (who's much better at houseplants than me). The leaves look fine. I don't recall seeing a Beaucarnea with reddish...
The lists look good. Bougainvillea notoriously likes dry, sunny conditions. The palm genus Chamaedorea has a number of great indoor species. I...
Monocots, alas, are rarely very good for cuttings (I can think of one exception: some palms can be persuaded to grow roots from the trunk, so you...
I don't know what's bothering the plant, but I'm far enough south that ponytails (Beaucarnea) live happily outdoors and can reach perhaps 15-20...
Everything looks quite accurate, including the info on air layering. Chamaedoreas make great indoor plants, even here in Florida, where they'll...
