  1. 1. Gardening with Clematis Lessons Learned <ul><li>Presented by Marilyn Glenn </li></ul>
  2. 2. What usually drives our first choice of a clematis to plant? <ul><li>Color Preference </li></ul><ul><li>Memories </li></ul>
  3. 4. Bloom Time – a primary consideration <ul><li>Winter </li></ul><ul><ul><li>“ clematis armandii” </li></ul></ul><ul><ul><li>Evergreen – no pruning; prune after bloom as needed to manage size </li></ul></ul><ul><li>Autumn </li></ul><ul><li>“ clematis paniculata” </li></ul>
  4. 6. Bloom Time – a primary consideration <ul><li>Spring </li></ul><ul><ul><li>“ Early small-flowered” </li></ul></ul><ul><ul><li>- Good for Beginners * </li></ul></ul><ul><ul><li>- Alpinas, Macropetalas, Montanas </li></ul></ul><ul><ul><li>- No pruning required </li></ul></ul>
  5. 9. Bloom Time – a primary consideration <ul><li>Spring </li></ul><ul><ul><li>“ Early large-flowered” </li></ul></ul><ul><ul><li>- most popular & most challenging to establish </li></ul></ul><ul><ul><li>- most prone to ‘wilt’ </li></ul></ul><ul><ul><li>- most challenging to prune – bloom on year old wood, prune after bloom as needed; unsightly foliage in winter </li></ul></ul><ul><ul><li>- the most suitable for containers; particularly </li></ul></ul><ul><ul><li>the doubles * </li></ul></ul>
  6. 18. Bloom Time – a primary consideration <ul><li>Summer </li></ul><ul><li> “ Late small-flowered” </li></ul><ul><li> - Good for Beginners * </li></ul><ul><li> - Integrifolias, Texensis, Viticellas & Others </li></ul><ul><ul><li> - easiest to grow </li></ul></ul><ul><ul><li> - least susceptible to ‘wilt’ </li></ul></ul><ul><ul><li> - extended bloom time (i.e. up to 2 months and even into fall) </li></ul></ul><ul><ul><li> - provide support structure, other plants to scramble onto and lots of room </li></ul></ul><ul><ul><li> - prune hard in late fall or early spring </li></ul></ul><ul><li> </li></ul>
  7. 19. Summer - “Late small-flowered” <ul><li>Integrifolias </li></ul><ul><li>- Non-climbing </li></ul><ul><li>- Least well known </li></ul><ul><li>- Can be divided as a perennial </li></ul><ul><li>- Do not take up a lot of space </li></ul>
  8. 26. Summer - “Late small-flowered” <ul><li>Texensis </li></ul><ul><li>- Nodding or upstanding tulip shaped flowers </li></ul><ul><li>- Derive from a wild species native to Texas </li></ul><ul><li>- Characteristic red color in most cultivars </li></ul><ul><li>- Grows vigorously - can be a “space hog” </li></ul>
  9. 28. Summer - “Late small-flowered” <ul><li>Viticellas </li></ul><ul><ul><li>- Produce an abundance of flowers on a substantial plant </li></ul></ul><ul><ul><li>- Excellent over arbors, arches and through climbing roses </li></ul></ul><ul><ul><li>- Great diversity of colors in cultivars </li></ul></ul><ul><ul><li>- Prune hard in winter, no unsightly foliage </li></ul></ul><ul><ul><li>- Not suitable for containers </li></ul></ul>
  10. 35. Bloom Time – a primary consideration <ul><li>Summer </li></ul><ul><li> “ Late large-flowered” </li></ul><ul><li> - Good for Beginners * </li></ul><ul><li> - prune hard in late fall or early spring </li></ul><ul><li> - can sometimes suffer from mildew </li></ul><ul><ul><li>“ New patio clematis” </li></ul></ul><ul><ul><li> - Ray Evison is the hybridizer </li></ul></ul><ul><ul><li> - good in containers </li></ul></ul>
  11. 43. 1 st Most Important Lesson to Learn <ul><li>“ The First Pruning” </li></ul><ul><ul><li>- Is when you bring the new clematis home </li></ul></ul><ul><ul><li>- Cut to the lowest pair of leaf buds on each stem </li></ul></ul><ul><ul><li>- If bloom buds are formed, prune as soon after bloom as possible </li></ul></ul><ul><ul><li>- You are forcing growth into the roots and promoting new stems to develop </li></ul></ul>
  12. 45. 2 nd Most Important Lesson to Learn <ul><li>“ Keep your clematis roots cool” </li></ul><ul><ul><li>- Provide lot’s of water (especially in July & August) </li></ul></ul><ul><ul><li>- Shade the roots with companion plants (i.e. roses, shrubs and perennials) </li></ul></ul><ul><ul><li>- cover with mulch or even flat stones to keep water evaporation down </li></ul></ul>
  13. 46. Common Mistakes to Avoid with Clematis <ul><li>Avoid planting two different pruning types together (i.e. Duchess of Edinburgh with Duchess of Albany) </li></ul><ul><li>Never plant two clematis plants in the same hole (one will survive at the expense of the other) </li></ul><ul><li>Avoid planting any clematis at the base of a tree </li></ul><ul><ul><li>- a “water hog” tree will kill the clematis </li></ul></ul><ul><ul><li>- a “space hog” clematis could kill the tree </li></ul></ul>
  14. 47. Common Mistakes to Avoid with Clematis <ul><li>Make sure you are able to provide water with ease </li></ul><ul><li>When ‘wilt’ strikes </li></ul><ul><li> - immediately cut the stems back to the lowest set of unaffected buds </li></ul><ul><li> - try moving the clematis to a new location </li></ul><ul><li> - act on the “3 strikes and your out” rule </li></ul>
