Phacelia purshii

Miami mist

 No garden should be without this uncommon annual with its delicate charm. No more than two feet tall it produces pale blue flowers with deeply fringed petals that produce a blue haze. Bees adore all the Phacelias and this one is no exception. It blooms in mid-May, starting bloom as Phacelia bipinnatifida is ending bloom, doing well in open fields and wood edges.

This plant wants to germinate in early winter so scratch in place in the fall. It will bloom for about three weeks, set seed and the whole plant will die quickly. Gather the seed and scratch it in where you want next year's display or let it drop; pull the plant and throw it on the compost heap or let it fade away under the new growth of other plants.

It spreads slowly by seed and is not aggressive. It covers the Miami Valley in Ohio in a blue mist, hence the name, Miami mist. This is the easiest plant to grow and provides a late spring display that can't be beat.

Easy Starters for Beginners

Easy Starters For Beginners

Here are some suggestions for easy starters. Some of them have large seeds that provide a lot of food for the seedling; others are just full of get-up-and-go. This doesn't mean that species not mentioned are difficult; they just require a little more care and experience.

Some seeds can be planted in situ, that is, where they will be growing as adult plants. There are advantages and disadvantages to this approach. On the good side, the plants don't experience transplant shock, this is a consideration for plants that resent transplanting or have tap-roots or brittle roots. On the bad side, the seeds may not be able to push through the duff and debris, and they have to compete with the other plants in the area.
Quantity of seed is another consideration. Seeds scratched in have a lower rate of return than seeds that receive more care in a pot or seed bed. So, if you have 100 seeds, scratch in, if you only have 10 seeds, baby those babies.

It is useful for the gardener to think of seedlings and fully mature plants as two different things. A mature plant can push through a thick layer of fallen leaves, seedlings seldom can. That's why it's best to plant seeds either in pots or in a seed-bed where you will remember to pull off the winter mulch, and weed and water the little ones.

*  Few insects or animals bother this one.

Actaea pachypoda                               doll's eyes

a good candidate for direct sowing into rock crevices.

Coreopsis tripteris

Tall coreopsis, Coreopsis tripteris, is a prairie remnant species found growing in the scour zone of the Susquehanna River along the York County line. Five to seven feet tall, this slender, open plant is a graceful accent in any garden.

Blooming from July into August, these three-inch flowers are showy and yet not gaudy. This species grows well in a wide variety of soil, from rich to poor, moist to dry. The plant slowly increases as a clump and is not thuggish. It does well in poor soil, as it doesn't compete well in a thickly planted setting. Pinch the leaves and enjoy the anise scent. Finches will enjoy the seed in the fall.
