Sweetgum's fall color

Sweetgum (Liquidambar styraciflua) is one of the last trees to show fall color. The fall colors are brilliant. A sweetgum tree typically shows a wide range from orange to yellow to red to purple. Often more purple than this one shows here. When all the other trees are bare, the sweetgum stands out far in the distance.

Sutera cordata

This is Sutera cordata 'Giant Snowflake'. For some reason this is called Bacopa. Maybe it is just to confuse us. The true Bacopa is in the Plantaginaceae family. Sutera cordata is one of the Scrophulariaceae family. Pictures taken October 18, 2009.

Revision 10/19: OK maybe this link will help explain this mess:

The plant itself doesn't care what you call it. It's only us humans that worry about such things. Here is another link to this plant, under what is (I hope) the correct name of Chaenostoma cordatum: Link

Arundo donax

This is Arundo donax, the giant cane. I have been seeing this planted in Indiana in a few places as an ornamental, it has the potential to become invasive and present a real problem. Its normal habitat is a semitropical environment but this is in Indiana in October and this plant is still green and vigorous. If you have some of this don't dump any part of it in the creeks or ditches or we may never see the end of it. Picture taken October 14, 2009.

Imperata cylindrica

This is Japanese blood grass, a cultivar of Imperata cylindrica. It’s on display at Purdue Horticulture Gardens, right along Marstellar St.

This red leaved variety of Imperata cylindrica is being used for landscaping in Indiana but it has the potential to be invasive. Imperata cylindrica has been rated as one of the ten worst weeds worldwide. The Japanese blood grass that you see around here is not supposed to spread via seed. Probably best not to plant this stuff at all, though. If you have it planted and want to get rid of it, don’t rip it out and dump it out in the woods!

As an indicator of this plant's ability to spread you might notice that it has taken over the space in the cracks between the bricks of the retaining wall.

Maximilian Sunflower

This Maximilian sunflower (Helianthus maximiliani) has so far failed to flower. The picture was taken September 30, 2009, and this plant still hasn't flowered, so I figured I might was well post it now without any flowers showing.
