Ephemeral plants

Hello, I am a student studying a BTEC national diploma and I am in need of some help acquiring 10 ephemeral plants for my plant profiles of which we have to do 200 over the course. If anyone can help it would be greatly appreciated. Many thanks,
Lewis

 

Ephemeral is a broad topic.
Do you have specific info that will help members.

See below for a broad definition:-

You'll have to be quick then, if it's 'ephemeral' you're after.

 

Thanks for responding to my post, I'm afraid I haven't much info other than we need 10 of any plant that is 'ephemeral'. This is new to me and is why I am asking whether there are any obvious or well known ephemeral plants (can be any you know of). Sorry I can't provide clearer information, this is the only one I have become stuck on. Many thanks, Lewis

 

When I saw this I immediately thought of desert ephemerals, probably because that kind interest me most.
One that we grow in gardens here is possibly Livingstone Daisy, (Mesembryanthemum), I even think there are certain kinds of melons that fit the bill.

 

How about poppies? They're the most ephemeral plants that I can think of
