LATER FLOWERING
LARGE FLOWERED CLEMATIS
All this group can be hard pruned during the winter period, and are often referred to as the Jackmanii group. Generally speaking they are relatively easy to grow and usually flourish with a modicum of assistance.
Flowers tend to be slightly smaller than the early summer flowering clematis but the plus factor is that the flowers tend to be much more numerous.
These like the viticella group are ideal for growing through and over shrubs and other plants because the plants have time through the winter and early spring to recover and grow without being smothered.
If you are growing in this way don't cut back too far but leave the stems well into the host plant where they will easily grow in the spring well out of the way of the majority of marauding slugs and other creepy things.
I think that the individual flowers quality of many varieties is not of the best but the overall effect is generally very good. It always brings to mind the saying 'Never mind the quality feel the width' which I think says it all.
NAME AND DESCRIPTION
- AI NOR
- A new colour that I have not met before in clematis from Estonia. A well rounded flower which is a peachy pink on the edge toning to a white centre. Best out of all direct sun .
- ALLANAH
- A rounded flower with spaced tepals. One of the clearest reds in the genus. Can be difficult to get to flower regularly. Try planting in full sun and pruning to 1.5m this usually works for me.
- AOTEAROA
- A New Zealand variety, very dark purple pointed tepals, said to be vigorous, I have not had it long enough to confirm if this is true.
- ASCOTIENSIS
- A clear mid blue with pointed tepals and green stamens Looks well with roses.
- BELLA
- Another clematis of East European origin. Well presented round flower of pure white with a contrasting centre, like all from the region masses of flowers.
- BLUE ANGEL
- The English version of the Russian name light blue flowers, which are simple and on the small side countered by the quantity of flowers. A heavenly asset to every garden.
- CARDINAL WYZYNSKI
- Nice red quite bright often confused with E. Markham within the trade which is unfortunate, tends to fade less and flower for longer.
- CAROLINE
- Pale pink flowers that somehow are very ladylike in appearance. I suppose I mean neat and charming!
- COMTESSE DE BOUCHAUD
- Bright pink with a touch of mauve lots of flowers over a long period
- CUBA
- Deep purple red with a distinct darker stripe a very well rounded flower. As the flower fades the colour changes and is still very acceptable, unlike some I can think of.
- DOROTHY WALTON
- Mauve pink long pointed tepals vigorous and floriforous providing a good later show. Height to 5m
- EMILIA PLATER
- This is not a clinging lady she must be given more than moral support. A mid sized rounded open mid blue flowers with the veins showing slightly darker. I have yet to be convinced but others rave.
- EMOJOGI
- Don't ask how to pronounce this plant it is well beyond even me. This is I suppose what you would call a different plant the semi pointed periwinkle blue tepals are not on first glance special. A closer inspection reveals as if the best watermarks were reserved for this plant.
- ERNEST MARKHAM
- Bright petunia red flowers over a long period
- ESPERANTO
- New from Estonia. Purple with a distinctive contrasting bar. Not normally as tall as the general run only reaching 2m with me.

- JACKMANII ALBA

- J. L. DELBARD
- Correctly 'souvenir de' violet edges to tepal with darker central stripe, not too bright for my taste.
- JOHN HUXTABLE
- A later flowering white of translucent quality with green centre when grown well is most attractive. Not terribly reliable some of the newer Estonian varieties are probably better.

- MEELI
- Well pointed purple crimson tepals that loose the red element as they fade. Like many Estonian clematis this does not lack vigour.
- MINISEELIK
- Or miniskirt for those that must know. Possibly the lowest growing of the group, this does not mean to say that it shy in flowering or has any other bad habits. Very round rose pink flowers fading to an off white centre.

- MONTE CASINO
- Another from the renowned Polish stable. I have difficulty in describing the colour to my satisfaction but a sort of maroon red.

- Long pointed greeny white tepals with a pale centre. Masses of flowers like all the East European varieties. One of my personal favourites.
- ROMANTICA
- Deep velvety purple certainly the darkest that I have ever seen I think that this plant is superb. Awarded a prize by the British Clematis Society.
- ROUGE CARDINAL
- Much darker and nicer red than the other red cardinal you may remember from polishing the doorstep many years ago. Pruning optional.
