I'm particularly fond of Species Daffodils because they naturalize, or multiply, over time. One bulb becomes two, then four and eventually my one-time investment in bulbs delivers a garden overrun with yellow flowers in early Spring.
Bonus for mountain gardeners: Critters hate the taste of Daffodil bulbs. Moose and deer aren't thrilled about the flowers.
Daffodils don't like rich soil. Putting fertilizer in the planting hole will hurt, not help, the blooms. If you're a real fanatic, you can lighten heavy clay soils with a little sand worked into the bed. (I'm too lazy.)
Squish 'em together. They look better in clumps vs. rows. Think about planting them under deciduous trees. Daffies need sun but they generally bloom long before the trees leaf out. Water until the snow flies. Bulbs put down roots as soon as they're planted. In bud and bloom, they require lots of moisture but Mother Nature generally pitches in with those proverbial April showers.
Species Daffodils and some of the older varieties multiply quickly:
- King Alfred Daffodils have stems reaching 20 inches, and flowers with a span of four inches or more.
- Dutch Master is an improved King Alfred, bred to multiply quickly in the landscape. 14" solid yellow flowers.
- Daffodil Carlton is prized for the speed and ease with which it grows and multiplies. 14-18" yellow flowers.
** I was shocked to discover that Walmart is selling King Alfreds this year. I'm giving them a try, though I suspect it's a cheaper hybrid version.
