They should be fine as long as they get enough light and any fish in the pond don't eat them. Goldfish will usually demolish the softer plant leaves. Other then that they should do OK. Vals is probably a good choice since most ponders I have encountered have harder water and high pH.

Hi
I find that most aquarium plants actually grow better in a pond. lol
Val makes a beautiful carpet given enough time. Swords,Cryps and Aponogetons also. Goldfish or Koi will be a problem as they will uproot them.. Of course there is always the problem of winter. I doubt most could survive a freeze. gary

Actually; all FW aquarium plants are pond/lake or stream/river plants in their native habitats and as Gary noted; will grow better outdoors than in an aquarium, but Koi or Goldfish will either uproot or nibble away on most of them.

However, they won't touch Java fern and will leave most Anubas alone. But Crypts and Aponogetons wouldn't last a minute with the smallest Goldie and generally need warmer water than a carp finds comfortable.

thank you all for your help! I'll be getting some plants soon.
