Established plants attached on some rock or wood

wanted, or help practical advice Hi admin I hope this ask is ok Brighton /sussex area I have 2 tanks, A corner unit jewel trigon 180 and a small 20x20x60. both have common and albino plecs the corner unit has as above plus red robin gourami and yellow labs My issue is plants, or lack of established healthy plants too improve water quality etc. the problem with any plant and I though is im clueless and useless keeping anything green alive. That or the fish manage too eat what is left of any withering greenery. the smaller tank has far less gravel than the larger so rooting anything is an issue, the corner unit has a mix of substrate & gravel 2-3cm deep but putting new plants in seems always a bust Is there anyone out there that has any plants that are established already attached on some rock or wood that are willing too part with I can collect within a few miles of Btn/hove via a mobility scooter & happy too trade decorations and air line filters of various types. the fish are health but without stating the obvious, active plants would be a bonus in either tank. when green fingers were being handed out I guess I was sat on my hands !
