Click on the flowers at left to see each previous introduction. I am cultivating and expanding the supply of previous introductions so that those of you who collect Mercer cultivars may add them if you choose to in coming years.

Meanwhile, this is a nice sampling. I have chosen some that delighted me most over the years to list here. They remain unique and offer qualitites that make them special despite the passing of time.

How to grow them
If you are buying previous inroductions, you probably are a collector or breeder looking for something specific to add to your collection or gene pool.Then again, you could be a relative newcomer buying for low prices and excellent value. Even customers who buy the high-priced spread sometimes need advice. One customer called to complain that all her new introductions from me died. All seven of them. After a few questions, she admitted she had planted them just like all her other bulbs: Six inches deep!

Here are some tips useful to beginners and experts alike:

  • Improve the soil with organic matter, such as chopped leaves, compost, bark, peat or composted manures
  • Add enough lime to raise your soil pH to at least 6.5 before planting. If you have alkaline soil (pH above 7.5), use powdered sulfur or other acid-forming material to lower your pH well below 7 before planting. Wait a few weeks to plant after adding large quantities of any amendment to let the soil recover its balance and to avoid burning your plants.
  • Plant the crown, the place where the roots meet the leaves, no more than 1.5 inches below the soil surface. Too-deep planting is probably the most common killer of daylilies.
  • Water every four or five days when there's no rain. Water every three days in hot sandy spots.
  • Fertilize lightly when planting and two or three times more a year, in spring and in late summer or early fall, with balanced fertilizer or a fertilizer high in nitrogen, if you have plenty of phosporus in the soil.
  • Mulch well if you live in the coldest states
  • Water is the most important of the above guidelines. More water almost always means better daylilies.
