About Veronica longifolia 'Blauriesin'

Veronica longifolia 'Blauriesin' · also called long-leaved speedwell, Blauriesin veronica · flowering

Veronica longifolia 'Blauriesin' is an upright clump-forming speedwell producing dense, tapering spikes of lavender-blue flowers from mid to late summer above narrow, toothed leaves. Long-flowering and excellent for cutting, it draws bees and butterflies and suits sunny mixed and herbaceous borders. Deadheading prolongs the display, and sturdy stems usually stand without support.

Mature size: 80-120 cm tall, 45-60 cm wide.

Watch for — Reduced flowering without deadheading: Spent spikes slow rebloom. Cut back faded flowers promptly to encourage a second flush.

Indoor size vs how big it gets in the wild

Veronica longifolia 'Blauriesin' stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward. Indoors and in a pot, expect 80-120 cm tall, 45-60 cm wide.. A pot, your light levels and a little pruning are what set the final size in a home, far more than the plant's theoretical potential.

Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Growth rate and years to mature

Veronica longifolia 'Blauriesin' 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: light feeder. a balanced general fertiliser or compost mulch in spring supports steady growth and flowering; avoid excess nitrogen, which can cause floppy stems.

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

How to keep veronica longifolia 'blauriesin' smaller

You are not stuck with the maximum size. For veronica longifolia 'blauriesin' specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting veronica longifolia 'blauriesin' is the main way to control its spread and refresh it.
Remove runners, plantlets or offsets as they appear if you want it to stay a single tight clump.
Keep it slightly pot-bound; a snug pot naturally limits how wide the clump can get.

The keep-it-smaller method, step by step

Lift the whole plant. Slide veronica longifolia 'blauriesin' out of its pot in spring when the clump has filled it.
Split the clump. Tease or cut the rootball into two or more sections, each with healthy roots and growth.
Repot one division. Put a single division back in the original pot to reset it to a smaller size; pot or give away the rest.
Remove offsets as they form. Through the year, detach new runners or pups to stop it spreading again.

How to grow veronica longifolia 'blauriesin' bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for veronica longifolia 'blauriesin' the accelerators are:

Give it a wider pot and let the clump fill it — width is exactly how this plant gets bigger.
Good light plus regular feeding maximises offset and runner production.
Leave plantlets and offsets attached and feed through the growing season for the fastest spread.

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

When veronica longifolia 'blauriesin' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for veronica longifolia 'blauriesin':

The clump bulging over the pot rim or splitting the pot — the cue to divide, not to find a bigger room.
A dense centre that goes bare or tired while the edges keep spreading.
Runners or offsets escaping across the shelf or into neighbouring pots.

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