Gardeners' Notes:

This is a big beautiful plant that gets around 5' tall in full sun; tolerates sandy soil; transplants well if done in the late fall or early spring; sometimes gets droopy and needs caging. Large beautiful flowers for many weeks in mid to late summer.

I bought two of these plants half-dead on clearance from Lowe's in June. I left them in the pot in a shady locale for a month to see if they would survive. I then planted them in a partly sunny locale. Not only have they survived but they thrived. In three months they have doubled in size and I am getting a few blossoms which I did not expect this first year -- and what blooms! Huge 7-8" fushia blossoms in late September! They are not fussy about soil or watering. I love these plants!

'Flare' was chosen as a Texas Superstar performer by the A&M Horticulture Dept. Tolerates a variety of soils. It continues to bloom profusely on new growth all summer and fall. Easy care, beautiful 6"-10" flowers are visible from afar. I also enjoy the hummingbirds they attract.

I purchased 'Rose Flare' as a 5' pot-bound bush.

After trimming away the root-bound portion, I repotted into larger pot with new soil and it continued to bloom. I'll do air-layering to get a shorter-fuller plant.
