About Daylily 'Catherine Woodbery'

Hemerocallis 'Catherine Woodbery' · also called Catherine Woodbery daylily, lavender daylily · flowering

Hemerocallis 'Catherine Woodbery' is an award-winning daylily prized for its unusual soft lavender-pink blooms with a green throat, produced in mid-summer. It is lightly fragrant and exceptionally heat-tolerant. Like all daylilies, it is highly toxic to cats and potentially fatal if any part is ingested.

Mature size: 65-75 cm tall in bloom; clumps 50-60 cm wide

Indoor size vs how big it gets in the wild

Daylily 'Catherine Woodbery' 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 65-75 cm tall in bloom. In the ground with no restriction it is a completely different plant — clumps 50-60 cm wide — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

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

Daylily 'Catherine Woodbery' 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: apply a balanced granular fertiliser (10-10-10) in early spring. a mid-season liquid feed with a bloom formula in late may/early june supports the long flowering season. excess nitrogen dulls the lavender colouring — keep nitrogen moderate.

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

How to keep daylily 'catherine woodbery' smaller

You are not stuck with the maximum size. For daylily 'catherine woodbery' specifically, these are the levers, in order of impact:

Divide the clump every year or two — splitting daylily 'catherine woodbery' 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 daylily 'catherine woodbery' 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 daylily 'catherine woodbery' bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for daylily 'catherine woodbery' 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 daylily 'catherine woodbery' light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When daylily 'catherine woodbery' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for daylily 'catherine woodbery':

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 daylily 'catherine woodbery' repotting guide. If you want more of this plant instead of a bigger one, the daylily 'catherine woodbery' propagation guide turns prunings into new plants.
