Staurogyne sp. ‘Low Grow’

Posted in Emersed Culture on November 22, 2009 by Bhushan Dalvi

Staurogyne sp. ‘Low Grow’ bloom.

I have been growing Staurogyne sp ‘ Low Grow’ for about 8 months in my emersed Cryptocoryne set-up. I have two more Staurogyne species (Staurogyne sp ‘Porto Velho’ & Staurogyne stolonifera ) growing along with this one under similar conditions and this one proves to be one of the slowest growing one for me. When I received a couple of stems initially they were grown submerged. It took a while for them to acclimatize to emersed culture. Finally Staurogyne sp ‘ Low Grow’ decided to flower yesterday. I think a recent increase in photo-period on my emersed set-up could have triggered the bloom.

Staurogyne sp ‘Low Grow’ grow very slowly in emersed culture even under good light. An interesting thing I observed with this species is its rate of growth does not change much even after moving it to a shaded location from a well light location. It grows about an inch every month in my experience under both high and low light conditions.




Polygonum hydropiperoides

Posted in Emersed Culture with tags on May 4, 2009 by Bhushan Dalvi


Polygonum hydropiperoides in my emersed Cryptocoryne set-up put out an inflorescence last weekend. P.hydropiperoides is native to both North and South America and is generally found growing along ponds and swamp margins.  Typically flowering from June through November,this plant had flowered for me in July of  2008 when I had just started my emersed set-up.


P.hydropiperoides is one of the less popular Polygonum sp. in the hobby. This is probably due to its less flashy colors as compared to the other Polygonum species.  P. hydropiperoides is a moderately difficult plant to grow submerged.


P.hydropiperoides has a straight upright growth pattern and tends to grow out of water if given a chance. Although this plant is not available from any of the aquatic plant nurseries it is easily obtained by collection throughout United States.

Hygrophila sp. ‘Araguaia’

Posted in Emersed Culture on February 8, 2009 by Bhushan Dalvi


I have been growing a few stems of Hygrophila sp ‘Aragaia’ emersed for about six months now. The stems were initially planted in a small 5gallon cube which has a 1.5” layer of old Aquasoil Amazonia II and Bright Sand. I had a 26 W 6700K CF bulb on it. The stems I initially got were grown submerged. I cut the top of the stems to approximately 2” and planted them. After not seeing any significant growth for about 3 weeks I moved them to my emersed Cryptocoryne set up. Initially the stems were planted in a pot with some Cryptocoryne willisii. After a couple of weeks I could see some improvements in the growth. The plant was putting out new leaves but the growth was very very slow. In December, 2008 I decided to plant the stems in their own pot and moved the pot directly under the 65W CF light I had over this tank.


Over the next few weeks the growth increased significantly but I would still consider it slow for a Hygrophila sp. Finally after six months it flowered for me confirming it was a Hygrophila sp.
