and I know what you mean--I struggled with English ivy and Bermuda grass for quite a while in Berkeley...I can call plants names in more than one language...odd skill, but there you are...
Sometimes it's difficult to be sure that we're talking about the same plant (a client's office space is dealing with bindweed...) without the scientific names.
However, in the case of this little beast, the scientific name itself
has been a source of confusion.
Most of the beautiful morning glories gardeners *like* to grow--the reds, purples, blues, etc.--are different varieties of Ipomoea
spp., which belongs to the Convulvaceae family
of plants (which is absolutely huge).
Bindweed's scientific name is Convulvulus arvensis *and* it's a member of the Convulvaceae family as well. So a very selective and [sorry
] truncated family tree looks like this:
Convulvaceae => Convulvulus => arvensis [aka prairie morning glory, aka noxious pest , Demon from h***, Spawn of Chaos, etc.]
Convulvaceae => Ipomoea => purpurea ("purple") [aka Common Morning Glory]
Scientific names may also help us discover previously unknown relationships among plants:
Convulvaceae => Ipomoea => batatas ("potato") [aka Sweet Potato]
Good luck with C. arvensis
