I wouldn't plant any Clematis with Lilys..not only are their needs different(watering..would rot the Lilys)..it just wouldn't do..the Clematis needs something to climb up and will get much taller than your Lilys and last longer..
I have C. Rosa "Zephrine Drouhin" companioned with Clematis "Hagley's Hybrid" and love it...I have them planted with the Umbrella Trellis I bought from J&P.
I think training a Clematis up your Cherry Tree would be nice..altho, I am worried about the sun requirements...I am sure there is someone here who can attest to which variety would do well with the amount of sun you get..as Mine all get more than that..so I am loss as to giving you an answer..goodluck...Jeanne

Thanks for the feedback. The cherry is horizontal, not vertical. There will be enough sun...however, it may be too far away from the water source for me to be consciencious about watering.

I have two zephirine drouhins on either side of an arbor. And I have paired one of them (on one side) with clematis called fujimusume. In its second year, I got one bloom which is noe fully opened. I am overjoyed. I never doubted the twp would do well togewther, but to see the two blooming side by side makes me very confident they are a fine match.

I would try asking this question in the clematis forum they may have an answer.

I have Zephirine Drouhin paired with Clematis 'Anna Louise', a group 2. I think this might be the same combo as in the WFF catalog?

Choosing among your list: I have Ville de Lyon and while they would overlap bloom, the color is too similar for my taste. My 'President' just finished blooming as Rosa ZD just started, so not much overlap in my yard at least. I like the idea of Polish Spirit-mine just started a few days ago, about the same time as ZD. I think the color contrast of purple and dark pink would be nice.

Does anyone know the bloom time for H.F. Young clematis? I just bought a few on clearance that I planned on planting with my Zephrine Drouhins, which I also have planted on either side of an arbor (great minds think alike, fasare). My Zephrines bloomed a few weeks ago and I probably won't have anything again until well into the summer. I'm hoping the H.F. Youngs will perk things up till then. What do you think?

I have 2 polish spirit and 1blue angel growing with my 2 Zephrine Drouhins climbing my deck. I really like the combo. They are all in full bloom right now.

HF Young's major bloom (in my experience) is very early-- too early, I think, for your ZD.

color choice is such a personal thing, but sounds like you're going for a purple/pink combo. The blues/purples you already own, Jack, Prez and Polish Spirit are usually very vigorous and would be pretty. They are blooming now in my area.
I agree with Jeanne about the lilies. I have a Carnaby in my cherry tree but they are so dense. Your light colored ones would show up but I'm not sure I understand about it being horizontal. One thing you'd miss planting your sweet autumn far away is the beautiful smell.

The cherry tree fell down! It is contorted and the shapeis too interesting to saw up and use for stove wood. Frankly, the reason I have the clem.s I do is that I got a "pallet' that came to about 4 bucks apiece. Thought I'd give some away, but haven't gotten round to it. I rather like the idea of complimentary colors, not contrasting.

At this point in the summer, If I use one of the "established" ones (one season, no blooms yet) when should I transplant it?

I also noticed that you with arbors are using one on each side.. That certainly makes more sense than just one, I guess.
