The species are now starting to bloom aggressively. H flava and H middendorfii are heavy in bloom. We have added H altissima, from Ollalie, and the roots are shown below. H altissima roots appear to be filamentous and fibrous, in contrast to say H fulva which is bulbous.

 

 

 

 

 

 

 

 

 

 

 

 

H dumortieri is in bud but not bloom yet. The H dumortieri flower has the brown tint on the sepals on the outer sides and one can see this pigmentation on the buds. The buds are also sessile, not branching, and they expand from the cluster.

 

 

 

 

 

 

 

 

 

 

 

Below is H flava. It shows a modest amount of short branching, not full branching as H minor or H multiflora but not sessile like H middendorfii. This shows great blooms and the plant was from Olallie and planted two years ago. It has multiplied extensively in that period of time.

 

 

 

 

 

 

 

 

 

 

 

Below is H middendorfii. It bloomed May 12, 2008. It was grown from seed and took three years to reach an aggressive bloom stage. It has naturalized well along the edge of a driveway, just eight feet from the street. It thrives in full sun and wet soil. The flower is full chrome yellow, is a day bloomer and is sessile like H dumortieri.

 

 

 

 

 

 

 

 

 

 

We also show the seedlings from 2007. Our process is as follows:

1. We place all seedlings in market petri dishes when picked. The we refrigerate at 38 F from time picked until mid December.

2. In mid December we then place them in growing flats which are heated and under growing lights.

3. In late March, first of April we placed them outside in 6" pots. This was the first year we did this. The pots were placed on planks in full sun. They were then hardened off and this years there were four or five days with the temps in mid 20s, a hard freeze. This killed off all of the initial foliage. Of the almost 120 pots we lost 10.

4. We then placed them in an unheated green house after a two week hardening off and kept them there for a month. Foliage returned and was quite strong.

5. We then placed the pots outside in mid May after return of growth. The hardened off plants are now growing very rapidly.

We show the results below.

 

 

 

 

 

 

 

 

 

We will be counting the seedling growing in the hardened off pots and will report accordingly. Many have only a single plant growing and others have multiple. We will also examine what plants failed to be hardened off.
