Rainy Side Notes
I love to pronounce this botanical name: zan-te-DES-kee-uh ee-thee-OH-pik-uh. It took many repetitions before I could speak her name accurately, but, as everyone knows, when dealing with a goddess—green or not—it is imperative to get her namesake correct.
The cultivar ‘Green Goddess’ is a stately calla lily beauty. However, if you stand next to her, you appreciate her gorgeous large flowers, made up of spathes camouflaged in white and green. From across the garden, this is not so conspicuous. You admire her beauty when you are close to this tropical-looking plant and see her blossoms fully exposed.
Even without the flowers, the plants stand stately in the garden. They reach three feet high and show off their undulating, arrow-shaped frondescence.
Like any self-respecting goddess, she demands special care in our Pacific Northwest gardens. As you know, our climate is dry in the summer, and she detests drought conditions. If we want to keep her happy, we need to water her.
She can grow in shallow water, provided you lift her out before winter. The plant does not like her feet frozen in water. If you want her in the garden, provide her with a deep drink of water once a week and mulch, mulch, mulch around her skirts to conserve moisture at her feet.
In the warmer areas of our region, where temperatures stay above 15 (0°F), mulching your plants ensures their survival. Some sources say it can survive down to zone 7 (0°F) gardens with mulching. However, if you live in the coldest areas of our maritime climate, you can lift and store the tubers like you would dahlias rather than risk losing your goddess.
‘Green Goddess’ is a fantastic choice as a cut flower. Pick stems when the flower begins to unfurl, and it will last up to or over a week in a vase.
