Expectations:
really?? not mine . . .
Provide good drainage and avoid overwatering. 

This plant forms a low, dense mat of foliage and has sunny yellow pompom flowers that bloom a long time starting in May. Leathery leaves are evergreen in winter, turning scarlet. Long lived.

Poncha Pass had pretty red seedheads. Kannah Creek is larger, but also has rusty red showy seedheads -- don't cut them back in winter as the seedheads are attractive.

What Kannah Creek should look like:



Experiences:
What am I doing wrong? Too dry? Too much water? Soil not lean or gritty enough? 'Poncha Pass' never thrived, and 'Kannah Creek' looked so good at first but through the summer and fall of 2020 declined badly.

The first fall when planted, 'Kannah Creek' had glossy leaves that were spectacularly red in winter.

In spring of 2020 it came back nicely and had cute green foliage and happy yellow flowers. Then it declined.

(I also planted 'Poncha Pass' in the kitchen courtyard in 2018. It didn't thrive in 2018 and 2019. It flowered, had cute tiny green leaves like a boxwood, but got smaller and finally only had a few leaves left. I took it out at the end of 2019.)

'Kannah Creek' is bigger. I planted it in fall 2019, at the front of the kitchen courtyard border fronting the 'Royal Candles' Veronica, but moved it to the center of the garden.

The first winter Kannah Creek had great winter color, deep garnet red and shiny. Nice. But it shriveled in fall 2020. In 2021 I potted it up.

I planted it finally in the birdbath garden in 2023 along the outer ring. And I got another in 2023 as well.

Kannah Creek flowers in 2020, foliage in 2022 and in its new home 2023

It stays a tiny plant. Fall color in winter 2024 was okay, but the plant is so small, and the newly planted one is even tinier, that it's hard to appreciate.
