Well quite big I think. We get these one's from the wonderful Aquadip who really grow quite terrific plants as you can see from the pictures. This particular plant is called Echinodorus Argentinensis
and they are by far the largest Mother Plants we have in stock at the moment. Part of the reason they grow so big in down to the care and attention they have received over the summer from Aquadip the end result is spectacular. You can also see a normal 5cm sized pot and the difference between that and the Mother Plant. And the 5cm pot isn't that small either at about 25cm tall.
and all for £13.99! So if you have a large tank or even a 4 foot one with an open top, you can be really creative with these plants and have an aquarium that would be the envy of your friends.
At this moment in time, these plants stand about 80cm+ - impressive heh! You can find this plant and all the other Mother Plants by clicking here.
