About Daylily 'Chicago Apache'

Hemerocallis 'Chicago Apache' · also called Chicago Apache daylily, red daylily · flowering

Hemerocallis 'Chicago Apache' is a vigorous, award-winning daylily producing vivid scarlet-red, ruffled blooms in mid-summer. It thrives in full sun with average moisture and forms clumping, grass-like foliage. Extremely toxic to cats — even small ingestions can cause acute kidney failure. Dogs may experience gastrointestinal upset.

Mature size: 60-75 cm tall in bloom; clumps spread 45-60 cm wide

Indoor size vs how big it gets in the wild

Daylily 'Chicago Apache' 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 60-75 cm tall in bloom. In the ground with no restriction it is a completely different plant — clumps spread 45-60 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 'Chicago Apache' is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: apply a balanced granular fertiliser (e.g. 10-10-10) in early spring as growth resumes, then a low-nitrogen, high-phosphorus feed just before bud set to boost bloom. avoid over-fertilising with nitrogen, which promotes foliage at the expense of flowers.

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

How to keep daylily 'chicago apache' smaller

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

Divide the clump every year or two — splitting daylily 'chicago apache' 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 'chicago apache' 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 'chicago apache' bigger or faster

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

When daylily 'chicago apache' outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for daylily 'chicago apache':

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

Daylily 'Chicago Apache' size — frequently asked questions

How big does daylily 'chicago apache' get?

Daylily 'Chicago Apache' reaches 60-75 cm tall in bloom when grown indoors, and far larger where it grows unrestricted (clumps spread 45-60 cm wide). Size here is about width, not height: the plant builds an ever-wider clump or sends out plantlets and runners while staying relatively short.

Is daylily 'chicago apache' slow or fast growing?

Daylily 'Chicago Apache' is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Daylily 'Chicago Apache' stays fairly low but widens over time — it spreads into a bigger clump by offsets, runners or rhizomes rather than shooting upward.

How long does daylily 'chicago apache' take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.

How do I keep daylily 'chicago apache' smaller?

Divide the clump every year or two — splitting daylily 'chicago apache' 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.

How can I make daylily 'chicago apache' grow bigger or faster?

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.
