Question
QUESTION: I have a clematis that is approx 2 years old. It appears to be seeding itself in various other places in my garden. Is this possible?  We have noticed several new plants and they appear to be clematis

ANSWER: Hi Tina,
Thanx for your question.  Yes, species clematis can and do self-seed and can become invasive pests.  I have clematis autumn glory I have been fighting for 15 years.  It's beautiful when blooming but it gets into everything.  I hope this helps.

QUESTION: Thanks so much, One other question.The clematis in the above question blooms purple that are good sized in early spring. Now what I think is the same plant, seems to be blooming small white flowers. Is this normal or do I have 2 separate plants for the cost of one?  Thank you again, you have been a great help. Tina

Answer
Hi Tina,
Thanx for your question.  You have two separate plants.  The purple is a hybrid you probably bought at a nursery or someone had planted.  The white one is the result of floating seed.  The species clematis you describe as small, white flowers I believe is Autumn Glory.  It has seeds with cotton on them and they float everywhere and get into everything.  The seed most likely, was blown into the area where your purple flowered plant is and now it is growing.  If you're not careful, it will choke out the weaker hybrid.  I would cut it off and try to dig up the roots.  They will grow sometimes right next to a desired plant making it impossible to remove them without harming the other plant.  In that case, label the one you want to keep, prune them both back and dig up the whole mess.  Separate them, treat pot the one you want to keep temporarily or move it to another place and treat the area both plants were in with Roundup.  Follow the directions on the Roundup package as I don't recall how quickly you can replant in the same spot.  I hope this helps.
