A genus of hardy annuals and perennials, native
Three annual species are worthy of mention here.
Leptosyne douglasii, with delicately feathered foliage
and yellow flowers, one and a quarter inches across,
freely produced on twelve-inch stems, makes a
neat and compact plant.
Leptosyne stillmanii has large, single golden-yellow
flowers, one and a half inches across, on eighteen-inch
Leptosyne calliopsidea also bears bright yellow flowers
on eighteen-inch stems in September.
These hardy annuals are sown in April out-of-doors
where the plants are to bloom, thinning the seedlings
to appropriate distances apart when large enough
They may also be sown under glass, temperature
55º to 65º F., in March, for planting
out in May. A position in full sun is essential
and a soul that is well drained.
They are excellent dry-soil plants and withstand
drought very well.
Propagation is from seed.
The flowering season is from midsummer until frost.
