Trees / Platanus / Exclamation! London Planetree

Exclamation! London Planetree

Platanus x acerifolia

Exclamation! came out of the Morton Arboretum's Chicagoland Grows program, selected for a strong central leader and a uniform upright-pyramidal shape that it keeps from the nursery row all the way to maturity. It also carries better resistance to anthracnose and to frost cracking than the older London planetrees. Sixty feet tall, forty-five wide, with the same peeling green, tan and brown bark.

Sizes and pricing

Off-the-lot means you pick it up and plant it yourself. Planted means we deliver it, plant it right, and back it with our Year One warranty. Tap a price to add it to your list, then send the whole list to Matt in one request. Want several of one tree, or a mix? Add them all and Matt quotes the count.

What does "gallon" mean? It is the size of the container the tree is growing in, not how many trees you get. The bigger the number, the bigger and more established the tree you take home, so a 30 gallon tree gives you shade and privacy years sooner than a 15 gallon one.

The Year One warranty

Planted by us? Then keeping it alive is our job.

Full warranty for one year after planting. This comes with any needed care and free check ups upon request. All needed treatments or pruning are included for first year. If tree fails to thrive, no cost replacement.

Planted right

Picked, delivered, and planted by a Board Certified Master Arborist.

We come back

Follow-up visits through the whole first year, not a wave goodbye.

Fed and pruned

Deep root feeding and structural pruning while it takes hold.

If it fails, we fix it

That is the warranty. No fine print, no chasing us down.

Want eyes on it longer? Year Two for 20 percent, Year Three for 15 percent of the planted price. Just say so in your quote.The sweet spot: most yards land at 15 to 30 gallon. Big the day it goes in, quick to take hold.Farther out? Ask for details if the project is more than 30 miles from Columbia.

Where it should go

Pick a spot with full sun. This one matures past 40 feet, so give it room: at least 20 feet from the house and 15 feet from other trees. Heavy Missouri clay is not a problem for this tree. Growth rate is fast, so you know what to expect season to season.

Not sure about your spot? Send us a photo of the yard with your quote request and we will tell you straight if it will work.

The first year in the ground

Water deeply once or twice a week through the first growing season, and step it up in July and August heat. Keep a 2 to 3 inch mulch ring around the base, pulled back from the trunk. Spring and fall are both good planting windows in mid-Missouri.

Or skip the checklist: have us plant it and Year One covers all of this. We feed it, prune it, and come back to check on it.

How is it different from Bloodgood?

Shape and reliability. Bloodgood is the older standard and grows into a big spreading tree at seventy to ninety feet. Exclamation! is smaller at sixty by forty-five and holds a tidy upright pyramid on one strong leader, which is why it gets specified along streets and drives. It was also bred with better anthracnose and frost-crack resistance, and that is the more meaningful improvement of the two.

What is frost cracking?

A long vertical split that opens in the trunk when winter sun warms the bark on the south side and the temperature then drops hard after sundown. It looks bad and it lets decay in. London planetrees are prone to it. Exclamation! was selected partly because it resists it, which matters a good deal in Missouri, where that exact swing happens most clear winters.

Do these photos show Exclamation! itself?

No. It is a patented introduction and there is no free-to-use photo of it, so these show London planetree generally. The bark, the seed balls and the leaf are all accurate to what you are buying. What they cannot show is Exclamation!'s tighter upright form, which is the main reason to choose it over a seedling planetree. Ask us for a photo of our current lot.

Can I buy a tree without having you plant it?

Yes. Every tree on the lot has an off-the-lot price, you pick it up and plant it yourself. The planted price adds delivery, planting, and the Year One warranty.

What does the Year One warranty cover?

Every planted tree comes with follow-up visits, deep root feeding, and structural pruning through its first year. If the tree fails in Year One, we make it right. You can extend it to Year Two for 20 percent and Year Three for 15 percent of the planted price.

When is the best time to plant a tree in mid-Missouri?

Spring and fall are both good windows. Fall planting gives the roots time to settle in before summer heat. Request a quote and we will work out timing with you.

Do you sell to landscapers and tree services?

Yes. The whole lot is open to trade buyers. Ask about volume pricing when you reach out.

Not sure which tree is right for your yard?

Tell us the spot and the job. A Board Certified Master Arborist picks with you, plants it right, and stands behind it for Year One.
