I’ll answer the easy part of your question. Lilies can’t not be deadheaded (old bloom removed) for additional bloom nor have its stalk pinched out (no bloom). They are basically a once and done plant.

Where are you located? How has the weather been? I'm guessing Z5? since you're just getting a first flush. What roses are you growing? All these things affect the answer. My big flower ones take up to 6 weeks to rebloom, but little singles such as Ballerina never stop.

I’m in zone 8b.

These are recently planted 2 yr old roses

Update- the flowers weren’t very big for wedding but they are now! Yesterday’s pic

That is just glorious!!! What exactly do you have planted there?

Front to back- alyssum, sweet potato vine, salvias, roses, cleome, envy zinnias, delphys. I don’t remember what’s the tall white one is. I didn’t intend on it being there. I planted the alyssum, cleome, zins and delphys from seed.

Didn’t the fountain covered in tile as planned. Stained it slate instead. We will finish it next summer. Grass took a beating from the guests and neglected during our 2 week vacation. Time to prune the flowers and re-seed.

Need to take the screen down. We used it for showing a video during the reception.

Absolutely unbelievable! It looks like something you would rent it some estate. Gorgeous!

Thank you for the kind comment. It was a lot of work but totally worth it.

Wow, the reflection in the water is awesome! And the ladies' hair is all so pretty, what a beautiful photo to memorialize the day!

The white flower is a Delphinium. Must have been a rogue seed in your packet.
