Common name: Day lily
The common name for Hemerocallis results from the fact that each flower lasts for only one day
However, they do continue to produce flowers in succession, for over two months, generally from June to August.
Remove the dead flowers daily to promote more flowering.
Due to their adaptability to hybridise, they come in literally thousands of varieties and colours.
They are a relatively easy plant to grow and are suited to wet or dry borders and or containers.
They grow in clumps of around 800-900mm (30"-36") high.
Hemerocallis in the Border
Daylilies appreciate good soil and sunlit conditions, and ample amounts of water throughout the growing season.
An annual mulch will help them through a dry summer.
Too much shade tends to result in plants producing fewer and or inferior flowers, this also leads to the plants leaning towards the light.
Cut the stems down to 50mm (2") above ground level after flowering.
Circa Week; 15-18:
Apply a low nitrogen fertiliser around the planted area
Add a mulch if required.
Plant out 500mm (18") apart in any good garden soil, in a sunny or semi-shaded location any time between now and April providing conditions allow.
If plants appear relatively dry give them a good soak prior to planting.
When planting out dig a hole larger than the root system you are planting.
Form a mound in the bottom of the hole and sit the plant on top of this and drape the roots down the sides of the mound.
The crown should be planted to no more than 25mm (1") below finished soil level.
When backfilling take care not to damage the roots, and do not tread it in as is done with some types of plants.
Adding compost / manure to the backfill soil will ensure that it is water retentive where it is needed most.
On completion give the planting area a good soaking and add a 75mm (3") mulch over it.
After planting, leave undisturbed for a number of years.
Divide and replant any time between now and April when conditions allow.
Poor flowering is often a sign that plants require dividing.
The divisions should be tidied up prior to planting.
Do this by trimming the roots and tops prior to replanting to reduce stress.
Plant divisions as described above for new plants.
