Design Journey: Business Set--Take One

Alright, fellow designers, this is a call for help. I've been staring at this for awhile now. As pretty as this logo is, it is causing problems applying itself to a business set. This is what I've come up with so far. But I'm not sure how I feel about it.

Front of business card. Standard 3.5" x 2" card.

Back of card.

Letterhead. Standard 8.5" x 11" size.

Front of envelope. I need to make sure that the yellow flower is up to USPS shipping code.

Back of envelope.

Feedback would be greatly appreciated. 

Working the contact info the for the company around the logo was tricky...So my solution was to simply move it to a different part of the piece. Does it work? 

What about the flow from piece to piece. Consistency? Is it there or does everything look just kind of thrown around. 

I've been trying to think of another solution but I think I have simply been looking at it too long and need some fresh eyes.
