What is this plant?

Someone who knew someone gave me this Its getting pretty big and looks like it has yellow buds.

I am no expert, but it looks like sweet basil to me. I am sure someone else will come along and correct or confirm though!

Hi there I agree the leaves do look like basil but I have never seen or heard of yellow flowers on basil...does anyone know of a certain kind?....the flower looks like an evening primrose...no I can't say for sure what it is but I would like to know too ???:)

The yellow flower is a buttercup (weed) growing very low in front of the mystery plant.

good on ya mate! ha ha ha....ooooh better pull the buttercups out quick...but the basil is looking good!

The yellow buds have appeared. Can anyone identify this mystery plant now?

You know what? I think it might be yellow loosestrife? I ordered plants from Rose Franklin's Nursery that look like that. Check it out @butterflybushes.com

Does anyone know if it's too late to prune a rugosa. Mine is really out of shape and I'm also wondering if a nice shaping might encourage more blooms once some new growth is pruned. Any ideas on this? Generally speaking, when is it too late to prune a flowering shrub?

The best time to prune any flowering shrub is AFTER it has flowered, as with Rosa Rugosa, to keep them from over taking everthing in sight,
(they are what is called the wild Roses or Ramblers) you should prune it right back after flowering, then give a rose feed around the roots, unless you want to enjoy the rose hips that appear in winter, the birds love them, if you need to prune these off, then take the shrub right down to about 8 inches from ground, as for other flowering shrubs, it all depends on what one it is, like Rhododendrons/Azalias, dont get pruned as you will cut of the next years flower buds, others just need a light prune WHEN they get too big, while others need a real short back and sides, so try look up the shrub or give the name on this thread and someone will come in and help you out, Good luck and happy gardening, WeeNel.

Lula61 you figured it out. It is yellow loosestrife. Thanks so much.

Lula61 - have you asked this question before? Sounds familiar, and I don't want to repeat everything....just curious?
