Definitely not wind 8-). Something picked up and moved a blossom before decimating it...

I do not have deer here but others have complained about deer damaging their azaleas and camellias.

Of our local plant nurseries, local nursery Calloways (known as Cornelius in Houston) has the largest selection of camellias. However, I should point out that new camellias appeared for sale a while back (as early as in the Fall in some nurseries) so there may be limited supply of camellias in local stores now. Lowes usually has a small showing that includes 4-6 different camellias. HD has a smaller yet sampling... 3-5 maybe.

These are some of the nurseries that the American Camellia Society recommends: Camellia Forest, Camelliashop, Camellia Haven, Gene's Nursery, Glen Read Camellia Nursery, Jarvis Nursery, Larry Bates Nursery, Mizzell's Camellia Hill Nursery, Nature Hills Nursery, Nuccio's Nursery

Texas hints:

Japonicas bloom late & have large leaves that do not tolerate the summer sun and will require afternoon and evening shade starting around 11am or so during the summer. Sasanquas bloom early (Fall-ish) & have smaller leaves but they can tolerate full sun in our daily 100+ summer days from July-September. I have seen them in almost full sun conditions in a local shopping center. They are planted in large pots but would definitely look better if they watered them more and had afternoon shade. Higo camellias are simply a subset of japonicas and should get afternoon and evening shade during the summer too. Camellia reticulatas have equally large sized leaves and should get shade like Japonicas. Since the sun is not as strong in the Winter and Spring, they all can get full sun at that time. For example, when tree canopies loose their leaves in the Fall and Winter, that would be ok. Sometimes, the leaves may turn bronze-dark green for a few weeks in the winter but then, they return to regular dark green. Amend the soil to acidify the soil if your location has alkaline soil. Plan on watering the soil only... about 1 gallon of water per watering at first. Water if the soil feels dry when you insert a finger to a depth of 4". Use 3-4" of mulch past the canopy. If you expect a drastic drop in temperatures that includes below freezing temps, water deeply the night before in order to minimize the chances of bud browning and drop. In response tocold temps, the shrubs may temporarily stop blooming for one or two months and then resume. For example, Japonicas bloom later than Sasanquas. The ones that I have start blooming in December or January. But once cold weather in Janary made them stop blooming. I kept them well watered until they resumed blooming in mid-March. You can add fertilizers in the Spring and later but in the hot summer and Fall I tend to use low nitrogen fertilizers only.

Yeah, fall is a great time to buy in Houston. I have bought from Calloways, arbor gate and buchanons

They do well in part shade or even full shade as long as its bright shade and no root competition
