Limnanthes douglasii, the poached egg plant native to Oregon seed was collected by David Douglas in 1820.

I don't think so Moon grower. Are there pink Limnanthes? They're "poached egg plant" as they're white with yellow "yolk" centres.

There is something called "easter egg plant" but it's the fruit that looks like eggs.

The Easter egg plant is actually a member of the Aubergine (or eggplant) family: Solanum melongena. MG is right about Limnathes douglasii.

Limnanthes douglasii is called poached egg plant, but Guest says the low growing plant has a large pink flower. Poached egg plants have yellow and white flowers. There is a species, L. douglasii ssp rosea, that is white with pink veins, but that's not the description given by the questioner.

Good point Beattie - didn't read question properly!

Ah well, never mind! Doesn't look as if anyone knows what it is. Please could you post a photo Guest? This guessing game isn't working.
