An excellent greenhouse or conservatory foliage plant this much improved once rare variety has recently become more widely available. The original plain green Fatsia japonica has long been useful as a decorative foliage plant for shady cool positions and has proved just hardy enough to go outside in summer or even permanently in sheltered courtyards and similar. (However for planting outdoors I’d recommend instead you go for the very similar but much tougher hybrid with Ivy, Fatshedera.)
This form of Fatsia (the origin of the name is lost), Spider’s Web, is attractively variegated with silvery leaf markings that are much more appealing than either the older plain or original variegata forms. Though to be fair it’s a tad more prone to burn or bleach if allowed to get too hot in dry air. So you do need to be careful as this can suffer rapidly in the wrong place, it needs dappled shade and preferably humid conditions not arid. Also be careful to water into the compost as splashing the leaves can cause marks.
On the other hand this is pest and disease resistant seldom suffering any such problems, indeed the only other thing to watch out for is waterlogging as that can soon rot the roots especially during colder times. Thus pot into a well draining gritty compost suits best.
You cannot start this from seed however small plants are inexpensive and soon bulk up if given large tubs, indeed given the root run these can eventually reach head height. However they stay conveniently compact in smaller pots, can be pruned if necessary, and the cuttings will root to make more plants.
The connoisseur could with diligence build a small collection with a half dozen Fatsia species and varieties available.
