Acrostichum grows in various water gardens around Houston. Mercer Garden has it growing in the ground, nowhere near visible water. I finally found a good sized one for sale at Nelson's for $10. I will try growing it in the sun. Moving from a jammed 1qt pot to a gallon tomorrow. I'm setting it in a ceramic pot with an inch or so of fresh water in the bottom. I expect it will do well, though I will likely have to take it in during winter cold snaps or take it to a friend's greenhouse with some other ferns over the winter.

PROPAGATION : I have propagated them by sowing the new little leaf that grows on top of the old leaf with good results.

This plant will only thrive outdoors in Zone 10 or higher. It will do well in low light, but needs high humidity in order to survive. I had mine in the kitchen window and it was failing, but it is now in a terrarium with nearly 100% humidity and doing well.

I have had this plant since early spring 2010. It is making small plantlets at the point where the stem joins the leaf. Can I propagate from these? I am borderline zones 8 & 9 so I will keep it potted and sheltered.

I love ferns and can generally grow them well but in past years I have killed two of these cuties.

Still not sure what I did wrong, but next time I see one of these at a nursery, I will try again - not to kill it, but growing one to large size must be quite a sight.

I have tried growing this fern outdoors twice here in zone 9b, and failed both times. Soon after planting the fern wilts and dies, probably because it requires much higher humidity than is available here. (It is sold as a terrarium plant).

When I saw this plant at the nursery, I just HAD to have it. So unusual. Planted outside in shady area. Protect from bright light as it will burn leaves; otherwise, pretty trouble free. It needs consistently moist soil.

I have rated positive b/c its a gorgeous plant but it s/b rated neutral b/c not the easiest plant to grow. Not easily available either.

Iv had the best success growing in a terrarium. But on 5/21 in growing in a no drain container as a covered patio plant. I will have to closely monitor moisture level since using a no drain container. It is a hassle but its beauty justifies the trouble IMO

Very unusual tropical fern: the leaves are small heart within a larger heart. They are medium green, leathery, glossy, beautiful. They need to be kept moist; allowing them to dry out will result in a possibly terminal loss of vigor; they also need to be protected from bright sun or the foliage will burn. Otherwise they are a carefree plant of uncommon beauty.
