'Glitters' has an interesting shape to the petals in it's corolla. And it has a very definate upright growth pattern. I mention this often because there are varieties which can go either way, upright or hanging (aka lax). Even some which are obviously uprights, are sometimes dense and bushy with allot of sideways growth occuring at the same time. Whereas others shoot straight upwards without a doubt! Glitters is one of those. The bamboo stake was a temporay necessity for this one because it had been in too much shade and had not grown the nice upright trunk it was capable of growing once it had been moved into a sunnier location.
