H. ‘Post-it’

Overview

'Post-it' is a sport of 'Mango Tango' registered in 2012 by G. Heemskerk of the Netherlands. It drops the parent's green margin entirely: the leaf is solid yellow, nearly round, 5.5 in (14.0 cm) by 4.7 in (11.9 cm), slightly shiny on top, moderately wavy and with a cordate base.

In the Garden

The original sport was measured at three years old as an upright plant 23.6 in (59.9 cm) across and 13.75 in (34.9 cm) high, with a moderate growth rate. Yellow scapes of 17.7 in carry near-white tubular flowers from early July to late August, and the plant does not set seed.

How it compares

'Mango Tango', the parent, has the same nearly round leaf shape but a broad medium green margin of 3 to 3.5 in around a yellow center, on a mound registered at 36 in across and 20 in high. Its registrant singled out how wide that margin is relative to the center. 'Post-it' is the solid yellow version, registered smaller.

'Peach Salsa' is in the same show class: pale yellow leaves, bright red scapes and petioles, and a fast registered growth rate on a mound registered at 20 in across and 12 in high. It received a Benedict Honorable Mention in 2025. 'Post-it' has yellow scapes.

'Firestorm' is a gold-centered option with a thin medium green margin of 0.1 to 0.2 in, registered at 25 in across.

Flowers and other notes

The registry gives no note on whether the yellow holds through summer. For general care, see the hosta growing guide.
