Randy:

I've used a soap and water solution as my first attempt at controlling a pest.

If you can get a liquid Castillian soap that would  be perfect.

I use one ounce in a quart of water for a dilution.

It's the soap molecule that dissolves the waxy coating of many bugs that does them in.

Second shot would be Neem or a product called Spinosad which is an organic composed of a bacteria.

David:

I purchased an aluminized HDPE cover for the greenhouse.

it is available in different percentages of transmission.

I use 40%.

it's a pain to drape it over the greenhouse.  My greenhouse is a lean to and it's hard to get up on a small roof to drape the cover over the glass.

I have a Biarum that is attributed as dispar but flowering time is off as well.

Couple of Ledebourias.

David:

I found a paper indicting that not all of the Biarum's flower in the fall. 

"Taxonomic Revision of Biarum - [Aroideana 29, 2_36] - Boyce 2006.pdf"

This came as Biarum aff. dispar.

Our Wiki states all Biarum's flower in October.

What gives?

Flowering today.

Thanks, I can put a name on it now.

No not sure of the ID.  I would consider sending a box full to the BX. Just wanted to be sure of the ID.

Corresponding with Rimmer we both  think it's H. non-scripta

 From B. Mathew, The larger Bulbs.
 
"Regarding H. non-scripta:  It grows to 35 cm in height with a rather one sided lax raceme of blue, pink or white long bell-shaped flowers. The raceme bends over at the apex , a point of difference between it and H. hipanica, and in addition the anthers are creamy-white."


So it  the apex that is bent over not necessarily the individual flowers.

I've had these at my home forever.  Not sure of the ID. As you can see from the images colors range from blue to pink and white. My best guess is Hyacinthoides hispanica due to the nodding flowers.

See PBS Apparently distinguishable from Hyacinthoides non-scripta by upright, not nodding, scapes.

"Conservationists believe the main threats to native bluebells in England are 'global climate change' and hybridization with 'Spanish bluebells' (Hyacinthoides hispanica) escapees from gardens, for now they remain prolific. Compared with other species, H. non-scripta has white anthers, as against blue anthers."

The Anthers in these cases  have the color of the petals in this case.
