My summer poinsettia is gorgeous, but I'm afraid to take it off the porch for fear the deer will eat it. Does anyone know if it is deer resistant?

I live in upper east Tn. (Kingsport, Tn near Bristol) and got a seed in with another plant a friend in Bristol had given me. When it came up she told me it was called Summer Poinsettia. I love how it reseeds and I never know where it will come up. It is such a unique plant and I love that it is at it's best in the hottest part of the summer. It is not aggressive at all in my garden but very easy to pull out if it is where I don't want it.

Have had success growing this plant. Love, love this plant! - - but so do the deer.

Neutral muttlover On Mar 29, 2011, muttlover from Quincy, IL (Zone 5b) wrote:

I've never seen it in real life, but the University of IL Extension service has an on-line video where they are recommending it for longer lasting color in the back of gardens. I was surprised because I thought it was strictly a southern plant, but the U of I guy said it's an annual (assuming in IL) that reseeds very heavily so you have a show continuing the next years too.

Does anyone have experience using the leaves or seeds as food (for humans) ?

I grew the Joseph's Coat here in central WV for the first time this year. It was spectacular and is continuing to form new flowers along the stem. I'd like to collect the seeds to sow more freely next year but I'm not sure how to "bag the seed head". Any advice?

Unusual burgundy-colored seedheads. Striking appearance from summer into fall. I left the seed heads on into the winter for the birds.

This plant can be seen at Disney's Epcot Garden and Flower Show each spring. That is where we fell in love with it. We just sow them directly into the soil and the plants seem to last through most of the summer. But, then they die back and actually re-seed during the end of the summer. Have not been able to keep them blooming on into Sept. and Oct. Does anyone else have this problem here in south Florida?

Fast growing beautiful plant loves direct sun. Planning on planting more next spring. Does anyone have suggestions about caring for these plants during the winter season? Thank you

This plant is very easy to grow and definitely likes the humidity of the south. I have noticed that if it is planted where it receives direct sunlight all day it stays a beautiful fuschia color with the hot pink (flowers)tips at the top. I planted some in shade and some in full sun. The ones in the shade stayed green with yellow tops and pink tops. The ones planted in full sun have stayed the beautiful hot pink and fuschia. My plants are loaded with seed pods so I should have enough for years to come...definitely an oddity but beautiful to look at. My tallest is appx. 4 1/2 foot but the person I received the seeds from, has some that are appx. 6-7 foot and just gourgeous to look at. Definitely would make you proud to have it in your garden. I am hooked.

An easy to grow, full-sun loving plant. Grew very well in my garden which contained at least 50% clay soil. I live in mid-north south australia which is very dry and hot in the summer when the plant has excelled but now it has died off in the winter (we are a frost prone area).

Nice quick growing herb/not frost tolerant/can take lots of heat/real easy to grow/good flaver,eat as you would spinach/grows from seed on most soils,even poor soils/does not need much fertilizer or water.I think it should be grown more.

Neutral Schmetterling On Sep 7, 2001, Schmetterling from Louisville, KY (Zone 6a) wrote:

Grown more for its brilliantly-colored foliage than its flowers. The foliage can be red, yellow, or green in various combinations.

Some red-leaved cultivars are referred to in catalogs as "Summer poinsettia". Provide a sunny growing area for this plant; it will also tolerate some dryness.
