Plant performance

The daylily is a relatively low maintenance perennial.  It prefers full sun (six hours or more), but many will do well in partial shade.  Most of the cultivars we offer were developed in a Zone 5 or warmer growing zone.  Here in SW Ontario, our growing zone is in the 5/6 range.  Many cultivars will thrive in a Zone 4 environment and tolerate a Zone 3.  It is strongly recommended that for Zone 3 gardens, winter mulching be done. 


A daylily is not a bulb based plant like the Oriental/Asiatic lily such as the Easter lily, or the Tiger lily that most people know.  Those are bulbous perennials, whereas the daylily (scientific name is Hemerocallis), has long, slender, fibrous roots.


Between the roots and leaves is a solid white core.  This core is referred to as the “crown”.  The leaves and scapes (i.e. flower stalks) are produced from the top of the crown, while the roots come from the bottom and sides of the crown.  The crown must be planted below the surface, but not too deep – usually only 1 – 2 inches.


Our plant heights will generally range from about 12 inches to 40 inches high.  Most of the miniatures (flower size is normally less than 3 inches in diameter) that we offer are in the 14 to 20 inch high range.  Most of the full size plants are in the 20 to 36 inch range.  These would have flower sizes that are normally between 4 and 6 inches, however, a number will exceed that and some will have a “wingspan” that will be in the 8 – 11 inch range.


It is hard to generalize, so that is why we provide size indications within our descriptions of each plant.  Please note that measurements,  descriptions, colours and characteristics are as  those provided by the hybridizer and/or the American Hemerocallis Society (AHS) and may vary in your garden based on the various environmental conditions.


Daylilies have multiple flower buds on each scape.  Each flower is in full glorious bloom for one day (hence the name day lily).  Because of the multiple buds, the plant will have a bloom period that normally spans a number of weeks.  The “season” descriptor on the website is a generalized indicator of when that particular cultivar (variety) blooms based on the hybridizer’s experience.  Many of the cultivars that we offer are registered as rebloomers, which means that the plant, given the right conditions, is capable of sending up new scapes after the initial bloom period and rebloom.  This however is dependent on growing conditions.  To clarify, a cultivar that was hybridized in Florida and is listed as a rebloomer, will rebloom in Florida, probably not rebloom in Manitoba with its short growing season, but may in other areas such as Halifax, Vancouver or Toronto.  Here in SW Ontario, I expect that most will rebloom.  Those cultivars that have demonstrated rebloom in our gardens have been marked as such with a “D”.

The bloom season tends to start in mid June for the Extra Early plants, and by mid July virtually all plants are in bloom, although some of the Late classified plants might hold off until the very end of July or very early August.  The rebloomers may produce flowers  until ????  We have actually seen  some plants that continued flowering until November snow fell in Keswick.  Here in our SW Ontario location we cut back the scapes on more than 60 different reblooming cultivars in the third week of November 2013.


One of our favourite things to do is to make our “rounds” each and every morning during the bloom season just to see what’s in bloom.  With multiple cultivars, it is different each and every day!


The colours you experience in your own garden may vary somewhat from those used in the descriptions, and from those seen in the sample pictures.  Keep in mind that the cultivars offered within this website, originate from many different locations.  Some of the originating locations include among others: Florida, Texas, the Carolinas, mid-western USA, Ontario & Quebec.  As such, temperature, precipitation, soil condition, sunlight hours and other growth factors may vary.  Each of these may have an impact on colour, size, bud count, bloom period, rebloom characteristics and plant spread.


That being said, all plants offered on this site, have wintered here (Zone 5B) and for almost every cultivar, the sample pictures have been taken in our gardens by either Cathy, or Daniel John O’Brien.  Generally, the daylily is reported hardy to zone 3.  If you are concerned and don’t have a heavy winter snow cover, mulching would be helpful.

“Sold Out – No Inventory” Items


There may be a some plants that are showing as Sold Out or No Inventory.  In reality, these plants are in our fields, but are of a low count (generally 4 or less) and we are either holding them for increase, or ensuring that they establish themselves following a relocation.


Many would be available for sale as single fan and are marked as such in the detail page of that specific plant.  Should you have interest, please inquire, and we will advise.


Display Only


Plants listed as “Display Only” are new acquisitions and are being held for increase prior to being offered for general sale.  Because these are new, we have not seen them in bloom, and as such can not state with certainty that they are true to name.  For this reason, we will not sell these plants until after their first bloom which is anticipated the summer following acquisition.  Dependent on their performance, we expect that these cultivars will be available for general sale the following year.  Photos for “Display Only” are those as provided from the hybridizer to the AHS at time of registration.  Once we have taken a picture of our plant, we will then substitute our picture for the registration picture which then illustrates that plant’s performance in our gardens, rather than those conditions under which the cultivar was developed.
