Can Creeping Jenny and Creeping Ludwigia Grow Together?

Creeping Jenny and Creeping Ludwigia share a workable water window around 15 to 26 °C, pH 6 to 8, and 4 to 15 dGH.

Both plants are comfortable in freshwater, so salinity is not a meaningful obstacle.

Both prefer moderate flow, so circulation can be planned as one steady pattern.

Their light and CO2 needs are close enough for one routine: Creeping Jenny does best with moderate light and no added CO2, while Creeping Ludwigia does best with moderate light and optional added CO2.

Both plants naturally lean toward the midground and background, which is why spacing, pruning, and final mature size matter more than they do in a more staggered planting mix.

Creeping Jenny reaches about 40 cm tall by 5 cm wide, while Creeping Ludwigia reaches about 40 cm tall by 8 cm wide. Use those mature sizes for the layout, not the small nursery portions you bring home.

Shade is worth watching, but it is usually manageable through trimming and a little spatial separation.

Creeping Jenny is typically rooted in substrate with inert substrate is fine and feeds mainly as a water column feeder. Creeping Ludwigia is typically rooted in substrate with inert substrate is fine and feeds mainly as a mixed feeder. That difference can make the pairing easier to arrange than two plants fighting for the exact same root or attachment zone.

Mature size is not the main thing working against this pairing, so normal maintenance is usually enough to keep the scape readable.

Both plants have fast growth, moderate maintenance, and beginner difficulty. That makes the maintenance rhythm predictable: watch for crowding, remove old leaves, and avoid letting one clump shade the other for weeks at a time.

The practical watch-outs are that both plants tend to work in the midground and background, so spacing matters more than usual; and that the layout needs a little thought so one plant does not slowly dim the other.

The strongest reasons to try the mix are that they share a workable temperature window around 15 to 26 °C; and that their flow preferences sit close enough to tune one layout around both plants.

Use this pairing when you want two plants that can share one routine without forcing a compromise at every step. It is strongest in tanks where mature spacing is planned before the plants fill in.

The simple success test is whether both plants still look healthy after the faster grower has been trimmed several times. If one keeps declining after routine care, the layout is probably asking too much of it.
