About Fuchsia 'Red Spider'

Fuchsia 'Red Spider' · also called Red Spider fuchsia, trailing red fuchsia · flowering

Fuchsia 'Red Spider' is a graceful trailing cultivar with slender, spidery single flowers in shades of crimson-red with reflexed sepals, giving a delicate, airy appearance. It is particularly well suited to hanging baskets and wall baskets where its elegant pendant blooms can be appreciated close-up. Not listed as toxic by the ASPCA.

Mature size: Trails 40-60 cm; individual flowers are narrow and elongated, up to 7 cm long

Indoor size vs how big it gets in the wild

Fuchsia 'Red Spider' does not get tall — it gets long. Size here is about stem length and how you train or cut it, not how much floor it claims. Indoors and in a pot, expect trails 40-60 cm. In the ground with no restriction it is a completely different plant — individual flowers are narrow and elongated, up to 7 cm long — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

Growth shows up as lengthening stems that trail down or climb up a support; the plant can be kept tiny or grown metres long from the exact same root system.

Growth rate and years to mature

Fuchsia 'Red Spider' is a moderate grower. Realistically, expect three to six years to reach mature indoor size, gaining a steady amount each growing season. Its feeding profile backs this up: feed weekly with a high-potash liquid fertiliser (tomato feed) from late spring through late summer. in a hot, sunny summer increase frequency to every 5-7 days to compensate for leaching caused by frequent watering.

Want this turned into the right next pot at the right moment? The pot size calculator and the fuchsia 'red spider' repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast fuchsia 'red spider' grows.

How to keep fuchsia 'red spider' smaller

You are not stuck with the maximum size. For fuchsia 'red spider' specifically, these are the levers, in order of impact:

Trim the longest vines back to the length you want — fuchsia 'red spider' takes hard cutting well and bushes out from the cut.
Cut just above a leaf node; each trimmed stem usually branches into two, so pruning makes it fuller, not sparser.
The cuttings root easily in water or mix, so "keeping it smaller" doubles as free new plants.
A trim once or twice a season is usually enough to hold its length.

The keep-it-smaller method, step by step

Decide the length you want. Pick the point each vine of fuchsia 'red spider' should stop — you can be aggressive; it regrows readily.
Cut just above a node. Snip about 0.5 cm above a leaf node so the stem branches there instead of dying back.
Root the cuttings. Drop the trimmed pieces in water or mix — they root in 2-4 weeks and can fill the same pot for a bushier look.
Repeat as it runs. Re-trim whenever it overshoots; regular light pruning keeps it both smaller and fuller.

How to grow fuchsia 'red spider' bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for fuchsia 'red spider' the accelerators are:

Good light plus a moss pole or trellis triggers the longest, fastest, largest-leaved growth.
Give it something to climb — many vines grow far faster and bigger up a support than trailing.
Feed through spring and summer and keep it consistently watered while it is actively running.

Light is almost always the ceiling. The fuchsia 'red spider' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When fuchsia 'red spider' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for fuchsia 'red spider':

Vines pooling on the floor or wrapping past where you want them — purely a trimming cue, not a repot one.
Bare, leggy stems with leaves only at the tips (usually a light problem, not a size one).
A tangled mass that has outrun its support and needs cutting back and re-training.

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the fuchsia 'red spider' repotting guide. If you want more of this plant instead of a bigger one, the fuchsia 'red spider' propagation guide turns prunings into new plants.
