Well... underplanting here is a sport.. with no ground space.. everything is underplanted with everything else.. little thought to food preferences..on anything.. only sunlight .and then only at planting time.. the sport is ...it's like a battle.. Iplanted ahoneysuckle with another vine.. A variegated Pandora's vine...both invasive to some degree... so they are pitted (planted ) together.. may the strongest survive... oh but they both do well...filling in neglected space the other leaves.. brugs aresimilarly planted...newseedlingsgoinoapot with it'sgroundcoverrirght away...sothey have to push up to stay above the competition..
trailing verbena is popular here.. as is bacobia.. which does real well till the shading starts...but by then the relieffrom the heat is welcomed..
is this considered an underplanting.. if it is bigger than the brug..
