I can recommend Tropica plants from The Green Machine (TGM), as they're often grown on considerably from the Danish nurseries.
I have recevied a lot of plants direct from Tropica in Denmark and the condition is second-to-none. However, with TGM's plants, they're top quality
and even bigger than usual.
You do pay a premium for Tropica though, so if you're on a tight budget then consider another supplier.
The plants received from another UKAPS sponsor, Fluid Sensor Online, were very good quality.
Aqua Fleur have a good reputation for quality vs. cost and supply various Maidenhead Aquatics stores. Ordering them in especially is worth considering as some stores are unable to keep their plants healthy in the long-term.
Aqua Essentials still supply their plant collections so they may be worth a look too.
there plants come already grown submersed
A lot of TGM's plants are also grown-on emerged (out of water) using hydroponics. This actually makes them more adaptable to a wider range of aquarium conditions.
Plants grown submerged (under water) in shops have adapted to the shops' water chemistry, so if yours differs, the plant may have a harder time adapting.
