It's probably 'New Gold'... I get most of my size listings from buchholz. I find that normally they have correct information listed. However, I don't think this is one of those times... it looks like this plant can grow to somewhere around 12' x 6' in 10 years.

hey .. photobucket is free.. but it isn't limitless .... i don't leave the pix floating in the ether forever .... hey .. i thought i would have to reload the tag line.. but all i had to do was upload them back to PB ... go figure ... if you find blanks of my pix in posts that do NOT reply to me.. you might try a direct email to me .... i hope it is all you dreamed of.. lol .. ken

its a conifer.. and a tree .. but not really a shrub ... though that term is commonly used ... just look at the bark ... you should be able to see .. how much it has grown this year... its still green... last year.. part green/part brown.. and all brown the year before that ... this will give you an idea of its ANNUAL GROWTH RATE .. and it will grow at that rate .. for the rest of your life ... size estimates in conifers are all at ten years ... presume at 20.. twice as big unless you go at it ... if a conjifer grows a foot per year.. its 10 year estimate is 10 feet .. etc ... where you are can affect size ... e.g. my MI growing season is a lot shorter than down south ... or the PNW ... google your latin name.. flip to images.. and you should see all kinds of sizes ... ken

Hey Bill thanks for the the help. I’ll keep things updated. I’m almost done working on the new cutting specific propagation chamber so I’ll have two chambers. One with blue LED, heat mat, and hopefully a misting system. That chamber will also only be 12” tall so the light can be closer to the cuttings. LED should also make it easier for me to control the temps. The other chamber I’ll use mostly for grafts without the misting just a humidifier. I’ll put some cuttings in there too, just to widen the possibilities of success. I read through an old thread that mentioned successes at times throughout the year. The broom is so easy to access I might try taking 5 or 6 cuttings in June, but the vast majority of my effort will be in winter. I’ve been in touch with someone who has had success rooting Tsuga brooms. Things are pretty straight forward: Dip n grow, mist, bottom heat, cool tops, wait 5-6 months. He does his in winter. I just want to be sure my due diligence is done and that I’m ready when the time comes. Here is what I have so far It’s roughly 2’ square. I will just use duck tape and plastic to seal off everything. The frame and base are all PVC and the top is plexiglass. I like PVC over wood. It’s still fairly inexpensive, but no rotting or fungal issues. I don’t glue most of the joints so I can take it apart or make adjustments later.
