Rarely do Cryptocoryne’s flower fully submersed, but when they do you commonly hear it happening with something easy like a Wendtii species; to wake up and see that my Cryptocoryne Sp. Affinis was sending up a spathe SUBMERSED made me jump for joy.
There are only two known photo’s of a fully submersed Cryptocoryne Sp. Affinis spathe, and only one of the two is an actual real submersed spathe. The reason I say this is the second spathe is going out of the water since the plant is only submersed in a few inches of water; I attached both known photo’s below for all to see:
Photo 1 True Submersed – http://crypts.home.xs4all.nl/Cryptocoryne/Gallery/aff/aff_x_M_988.jpg
Photo 2 Not Truly Submersed – http://www.fnzas.org.nz/wp-content/gallery/plant-database/cryptocoryne-affinis-flower.jpg
Even in the emersed state Cryptocoryne Sp. Affinis is not easy to flower, nor cultivate, which is why most international plant nurseries have stayed away from this plant OR can only offer it at certain times of the year. This makes this submersed spathe all the more special (in my opinion), especially since the plant is in a tank that is 22 inches tall.
The spathe is probably not fully developed yet but I don’t imagine it will get much larger then the pictures below as my research shows the spathe’s to commonly stay between 30-40cm.
The pictures are in order from when I first saw the spathe (3 days ago, Dec 9th) to now (Dec 12th):
I recently started dosing fertilizers in this tank on a more regular basis, as well as I removed the shade cloth and increased CO2, I’m not sure if this has anything to do with the plant sending up the spathe but it only started to develop after increasing light/ferts/co2.
As always here are the specs of the tank:
Lighting – Marineland Aquatic Plant LED
Filtration – Marineland C220
CO2 – 2 BPS
Fertilization – Micro + Macro alternate days
Substrate – FAKE Plastic Gravel (Surprising eh?)
