Editor's Journal: Stonecrop

In the Flower Garden, Alliums are continuing to be important and it is getting tall fast with Cannas and Gingers that were wintered over under glass being planted out along with more tender perennials than can be counted. It should be quite a show with many new plants being tried this year. The big are getting bigger in the Woodland--the Gunnera leaves are up to four feet across and the plant is up to six feet high and ten feet wide, and the Petasites is up to five feet high with leaves up to three feet wide. Also in the Woodland, a don't miss Arisaema and a Pulmonaria named after its price! And in the Gravel Garden, a Syneilesis and a Baptisia with just the right neighbor. Continue.

Rhododendron, Petasites, and Gunnera
Gunnera manicata inflorescence
The three foot high flower stalks have a series of thick "fingers" radiating out and curving up and carrying the amazingly small flowers. A member of its own family, Gunneraceae and native to southern Brazil, the genus is named after J. E. Gunnerus, a Norwegian bishop and botanist.
There is a clump with about a dozen of these amazing flowers--the long, thin, pointy spadix seems to be a continuation of the stem which turns black as it makes a right angle through the spathe and then turns back to green as it makes another right angle and turns upward after being pinched by the spathe.
Pinellia tripartita
Kerria japonica
A member of the Rosaceae family, native to China and Japan, brightening up the Woodlands with its clear yellow flowers. A shrub growing to six feet, this is the only species of the genus, although there are several cultivars including the double--'Pleniflora' and the variegated--'Picta.'
A spectacular cultivar that may have been named for its price!
Pulmonaria 'British Sterling'
Anemone sylvestris
Bright white flowers with large deeply cut leaves of a very spreading perennial.
A light purple Geranium with small finely cut leaves.
