Gardeners' Notes:

Positive prkist On Jun 30, 2006, prkist from Virginia Beach, VA wrote:

It came with the house here in Va Beach, VA and I nearly pulled it out as a weed this spring. So Glad I did not!! It is very petite and just so lovely. It gets 60% sun and seems totally happy with that. Thanks for telling me to deadhead to prolong the blooming. A friend saw it and identified it so I could learn more about it here. I have been gardening for 62 yrs and there is enough new info out there to see and learn about to keep me going to 100.

This is the cutest little plant! They dont take up much space, and the buds do resemble hot air balloons before they open. It does like a little more water in really dry spells, and once established can tolerate drought. Very easy, beautiful plant to care for.

This old fashioned favorite is one of the last to sprout up in the spring. It is easy to overlook its sprouts and pull it out for a weed!

My oldest daughter picked this plant out for us and it really bloomed a lot at first, then slumped all summer and started back blooming again this fall. I wonder if it just doesn't like quite so much heat. It's planted in full sun here in OK.

Positive kooger On Apr 19, 2004, kooger from Oostburg, WI (Zone 5b) wrote:

I enjoy this plant, it spreads slowly every year and is about 2 ft. across in it's 4th year. It is a sleepyhead and is the last plant to come up in the spring. I thought it had died the first 2 years and then finally it came up! Needs deadheading.

Neutral dogbane On Nov 9, 2003, dogbane from New Orleans, LA (Zone 9a) wrote:

This plant is a hybridized native of the southern US. The native form is tall and sparse, but has the same gorgeous flowers, though a somewhat lighter color. The native is usually found in very harsh environments like sand ridges or along the edges of salty or brackish marsh. With this in mind, know that the biggest problem with cultivating Balloon Flowers is killing them with kindness. This little masochist wants to be in hot, dry, nutrient poor places and won't survive long if over tended.

Positive MartyK On Jun 4, 2003, MartyK from Memphis, TN (Zone 7b) wrote:

It grows in full sun or dappled sun. If you deadhead, it blooms from late May til October. Mine in dappled sun reach 15-20" in height. The ones in full sun are 8-10".
