|Other than the Ivy Geraniums all these annuals have North American heritage: |
Lantana camera, Melanopodium divaricatum, Zinnia 'Profusion' series, Salvia farinacea.
|This Beach Sunflower grew to about 4 ft in a pot.|
|These Sulfur Cosmos are competing|
for space with some culinary mint.
|After blooming the flowers of this Sneezeweed turn white |
and disappear into the foliage. These did reseed
into the pot the following year.
The native ranges of these next two plants actually include the Mid-Atlantic region.
|Adlumia blooms from late June to frost. The shiny black seeds |
are easily collected by shaking the dried flowers on the vine.
Miami Mist, Phacelia purshii, is a winter annual that is native to Mid-Atlantic states and lower Mid-West. It has small, fringed lavender-colored flowers that bloom in spring. As a winter annual, it needs to get its start in the fall, as temperatures cool and moisture increases. From what I have read, the seed should be exposed to warm summer temperatures to break the seed dormancy. So I will direct sow some of these in June and also put some outside in small pots where I can keep an eye on them. They overwinter as a rosette of leaves, then put forth a flowering stalk the following spring.
North American Annuals Not Hardy in Maryland
|These Bluebonnets were growing at the Lady Bird Johnson Wildflower Center in Austin, Texas. |
I doubt I will have such good results in Maryland, but I'll try.
Spanish Flag, Ipomoea lobata, is an annual vine from Mexico that grows to 5-10 feet. I found no records that show it to be self-sustaining in the contiguous US. It produces racemes of tubular flowers in mid-to-late summer that change from red to orange and then white as they mature. These flowers are favored by hummingbirds. I've seen this vine used to quickly cover a chain-link fence. When starting from seed, scarification and presoaking in warm water is recommended.
|Texas Sage blooms from late July to frost.|
As I recall, bumble bees would get nectar by landing on the top of the flower and sticking their tongues into the calyx tube at the base of the flower. It will be interesting to see how our hummingbirds approach this flower.
