Hi Jeff,
I bought very small plant at a native plant sale back in 2008. Two years later, it has grown quite a lot. It isn't a huge plant, but I'd say it's 2 feet across and 2 feet high. I love the white blooms. Got lots of seed from it this season.~~Angie

I had one, but it didn't survive. So far, you are doing better than I am.

Jeff, How old are your plants and where do you have them planted?

Gosh, Fine Gardening says they only have a 5-10 year life span.

Here is a link that might be useful: Ceanothus americanus (Mountain sweet, New Jersey tea, Redroot, Wild snowball)

Jeff, I've had one for two years, and it's only about 18 inches tall. I'd say a very slow grower! I got one of the Marie Bleu variety--has blue flowers, and it has grown to about 24 inches in one year. It is really healthier looking than the white flowering one.

I started seeds of the white flowering variety this past spring. The plants are about 5 inches tall. Hope to put some more out next spring.

This has been one of those plants that has taken me quite a lot of effort to really get some going. I lost a few before any of them took off.

I have one started from seed two years ago - it's 10" tall. I have two others planted bare-root this spring - they're a bit larger. But certainly not 36", the advertised full-grown height.

Thanks for your experiences. It gives me some perspective.

Jeff

What is the bloom time on it? And, where did you get your blue flowering one, Sandy?

Susan

Mine blooms early in the Spring Susan. I think it's in bloom when my Forsythia is. You are welcome to some seed if you'd like some.
