Deanna your ASK is beautiful. This summer has been kind of weird, it was hot/cold/hot/cold with humidity, many of my plants got some kind of moldy fungus including my coleus and autumn joy sedum. Anyway, I am thinking of transplanting a mature one to another spot of my shade garden this weekend, has anyone tried transplanting in September? Will there be enough time for the roots to settle before frost hit? I prefer to do it now because temp is cool so easier on my body, doing it in spring is cold and wet :) I remember FrozeBudd has done dividing a mature ASK before but I can’t remember if it was spring or summer or fall…how much root did you have per division, like 1 - 1.5 feet long? I remember you mentioned the roots were woody and difficult to cut, how are your 2 ASK doing now?

Thank you for posting your pictures. I just picked up one of these a couple weeks ago and am still deciding where to plant it. Think I have a good spot now =)

I have grown both. The Sun King can take from light shade to full sun. Mine was grown in light shade, but probably in the PNW with less sun and temperature would have done better in full sun. I bought two Pseudopanax laetus spring of 2014. One I planted under the canopy of large hemlock trees, the other out in full sun. Deer chewed the one under the trees down to a nub, but after I sprayed it with deer repellant it has recovered. The one in the sun was missed by the deer but I spray it with repellent which makes them lose interest after they did find it. It has gone from the one foot tall plant I bought to over three feet tall. They went through both winters without any damage, but then our last two winters weren't very cold. The 2014/15 winter got down to around 20 degrees, while this winter only got to 27 degrees. From what I have read they can't handle much below 15 degrees, but these being from Dan Hinkley's collection that Monrovia Nursery is selling, with him claiming them to be hardy into zone 7 I thought I would give them a try. Mr. Hinkley is known to find the hardiet sources of plants he collects. When we have a real Arctic storm with temperatures into the low teens or lower, then we will know how they will do here. I do like the look of the plant with evergreen palmate leaves giving that jungle look. If you like the look of P. laetus I would suggest you get Schefflera delavayi, Schefflera taiwaniana, or Schefflera fengii. All of these are very hardy west of the Cascades in the PNW. The director of the Rhododendron Species Foundation, Steve Hootman, says these three are the hardiest of the Schefflera. I believe him since I have all three of them and they have handled temperatures into the low teens. The owner of Cistus Nursery, a mail order source for S. delavayi, claims S. delavayi is hardy to 0° F. You can buy S. fengii from Far Reaches Farm, if they haven't been sold out yet. They also sold S. delavayi in the past. Their source of S. fengii is from Steve Hootman's collection from the RSF which also sells it from time to time. The RSF have Schefflera minutistllata in their spring catalog, and I saw three plants for sale at their gift shop nursery. I don't know how hardy they will be since I have only had them for three seasons. Schefflera taiwaniana has been sold throughout the PNW nurseries that handle Monrovia plants. This is another Dan Hinkley plant.

A NH gardener who isn't on the forum much has one about that size. I don't know how long it takes to get there, but I'm wondering how much moisture plays a part. As an example, hosts are drought tolerant, but they come from a high moisture environment. They reach their full potential with adequate water. Wondering if Aralia is the same. At least I know with our short growing season that this size is possible! Wish I knew more about how to get it this size, other than time.
